Conservation Currents, Northern Virginia Soil and Water Conservation District, Feb 2004). Polluted soil poses a severe problem for both ecosystem health and land development. Because soil lies at the confluence of many natural systems, soil pollution can be spread to other parts of the natural environment. Groundwater, for instance, percolates through the soil and can carry the soil pollutants into streams, rivers, wells and drinking water. Erosion can create the same problem. Plants growing on polluted soil may contain harmful levels of pollutants themselves, and this can be passed on to the animals and people that eat them. Dust blown from polluted soil can be inhaled directly by passersby. Additionally, in an urban setting such as Fairfax County, polluted soil makes valuable open land unusable for parks, recreation or commercial development.. Despite the benefits of cleaning polluted soil, remediation often never takes place because of the cost and effort of the work. Both soil minerals and ...

By B.DULGUUN. The public should stay alert of soil-borne diseases because the risks of flood and soil pollution is increasing as the weather becomes warmer, warns experts.. Doctors say that a large number of people are infected with intestinal infectious diseases such as diarrhea and dysentery in early April as a result of floods, water contamination and soil pollution. They call this period the infectious disease season.. Soil-related diseases are extremely harmful, particularly to the health of children. However, most people arent aware of its cause, consequences or ways to prevent it. Government agencies conduct research and study on this issue, but the public still remains ignorant as they are not being informed about the findings.. The General Agency of Specialized Inspection, Mongolian Academy of Sciences Institute of Geography and Public Health Institute, and others have already studied soil pollution. The study shows that the main cause of soil pollution are the increasing number of ...

Metals released by the extraction with aqua regia, EDTA, dilute HCl and sequential extraction (SE) by the BCR protocol were studied in urban soils of Sevilla, Torino, and Glasgow. By multivariate analysis, the amounts of Cu, Pb and Zn liberated by any method were statistically associated with one another, whereas other metals were not. The mean amounts of all metals extracted by HCl and by SE were well correlated, but SE was clearly underestimated by HCl. Individual data for Cu, Pb and Zn by both methods were correlated only if each city was considered separately. Other metals gave poorer relationships. Similar conclusions were reached comparing EDTA and HCl, with much lower values for EDTA. Dilute HCl extraction cannot thus be recommended for general use as alternative to BCR SE in urban soils.. ...
The zero waste trend could have a friend in the form of biosolids. Biosolids are the materials produced after domestic waste is treated in urban wastewater systems. In the past, most of this solid material was transferred to landfills. But, processes developed over the past few decades can create exceptional quality biosolids. These new EQ biosolids are low in pollutants and pathogens, but high in nutrients. They can be applied to agricultural or urban soils needing fertilizer and other soil health improvements. That reuses a former waste material - and helps the environment along the way.. Biosolids are valuable because they are rich in nitrogen, a key nutrient for plants. But, only a fraction of the nitrogen in biosolids used as fertilizer becomes available to plants. This fraction is called bioavailable nitrogen. We need to know how much nitrogen becomes bioavailable when we add biosolids to the soil, says Odiney Alvarez-Campos, a researcher at Virginia Tech. We want to supply ...
Hydrocarbon-contaminated aquifers can be successfully remediated through enhanced biodegradation. However, in situ monitoring of the treatment by piezometers is expensive and invasive and might be insufficient as the information provided is restricted to vertical profiles at discrete locations. An alternative method was tested in order to improve the robustness of the monitoring. Geophysical methods, electrical resistivity (ER) and induced polarization (IP), were combined with gas analyses, CO2 concentration, and its carbon isotopic ratio, to develop a less invasive methodology for monitoring enhanced biodegradation of hydrocarbons. The field implementation of this monitoring methodology, which lasted from February 2014 until June 2015, was carried out at a BTEX-polluted site under aerobic biotreatment. Geophysical monitoring shows a more conductive and chargeable area which corresponds to the contaminated zone. In this area, high CO2 emissions have been measured with an isotopic signature demonstrating

There are a lot of eco-pros and cons to using synthetic turf. In this particular situation, where the garden is sunken one floor below the street, and very little light is able to penetrate the area, the synthetic turf is just about the only green solution for a true, clean play surface. Also, in this application, we dont have to worry about the one con usually brought up - that it gets hot. Here, that isnt a problem.. Also on the plus side, the material is made from recycled plastic and held in place by recycled tire crumbs. A two-stroke engine, the kind in lawn mowers, creates significantly more pollution than a car (since there is no catalytic converter), so with synthetic turf, that carbon load is eliminated. The surface is pervious and yet sheds water, if properly installed with 6 to 12 inches of drainage media beneath.. On the down side, synthetic turf can get hot and it doesnt put oxygen back into the air. Its not the right thing in all cases, but it is the groovy eco-solution in ...

Phytoextraction has been proven effective at a brownfields site in Trenton, New Jersey for remediation of lead-contaminated shallow soils (Blaylock et al., 1996). Approximately 50% of the lead was removed from the surface soil (~ 700 mg/kg) in order to achieve clean-up standards (400 mg/kg) in one year using Brassica juncea, a relative of the mustard family. For phytoextraction to be effective, one needs vigorously growing plants (and 3 tons dry matter/acre-yr), an easily harvestable aboveground portion, and a plant that accumulates large amounts of metals (~ 1000 mg/kg) in aboveground biomass. To achieve clean-up within three to five years, the plant must accumulate about ten times the level in soil (for example, if the level in soil is 500 mg/kg, then the concentration in the plant must be almost 5000 mg/kg to clean-up the soil in a few years). Some sites have metals that are bioavailable while others do not. Generally, cadmium, nickel, zinc, arsenic, and copper are relatively bioavailable ...

Sustainable consumption and production is about promoting resource and energy efficiency, sustainable infrastructure, and providing access to basic services, green and decent jobs and a better quality of life for all. Its implementation helps to achieve overall development plans, reduce future economic, environmental and social costs, strengthen economic competitiveness and reduce poverty.. At the current time, material consumption of natural resources is increasing, particularly within Eastern Asia. Countries are also continuing to address challenges regarding air, water and soil pollution.. Since sustainable consumption and production aims at doing more and better with less, net welfare gains from economic activities can increase by reducing resource use, degradation and pollution along the whole life cycle, while increasing quality of life. There also needs to be significant focus on operating on supply chain, involving everyone from producer to final consumer. This includes educating ...

This paper presents a quantitative method for the risk-based evaluation of Total Petroleum Hydrocarbons (TPH) in vapor intrusion investigations. Vapors from petroleum fuels are characterized by a complex mixture of aliphatic and, to a lesser extent, aromatic compounds. These compounds can be measured and described in terms of TPH carbon ranges. Toxicity factors published by USEPA and other parties allow development of risk-based, air and soil vapor screening levels for each carbon range in the same manner as done for individual compounds such as benzene. The relative, carbon range makeup of petroleum vapors can be used to develop weighted, site-specific or generic screening levels for TPH. At some critical ratio of TPH to a targeted, individual compound, the overwhelming proportion of TPH will drive vapor intrusion risk over the individual compound. This is particularly true for vapors associated with diesel and other middle distillate fuels, but can also be the case for low-benzene gasolines or even

The objective of this study was to assess the effects of heavy metals on microbial decomposition of cellulose in heavy metal-contaminated soils using a cotton strip assay. The assay is a measure of the potential of soil microorganisms to decompose the plant polymer, cellulose. Cellulolytic activity in soil was assessed by determining the reduction in tensile strength of the buried cotton strips over a 25- and 45-day period. Soils were obtained from a rifle range that contain high levels of lead, copper and zinc. The site has been used for approximately 50 years, resulting in metal levels of up to 30,000 mg/kg of lead, 4000 mg/kg of copper and 600 mg/kg of zinc in the most contaminated soils. All the metal-contaminated soils had lower degradation rates than the uncontaminated soils tested. Among the contaminated soils, however, the heavy metal concentration was not the major factor in determining the loss in tensile strength of the cotton strips, where cellulose decomposition was governed by ...
Background Soil pollution with heavy metals seriously threatens soil quality, food safety, and human health. This study was conducted to determine the soil pollution level and ecological risk assessment of different heavy metals in agricultural soils around Nakhlak Pb-Zn mine, located in Anarak district, Nain county of Isfahan province.Methods A total of 50 soil samples were collected from agricultural land around Nakhlak mine and analyzed to determine the concentrations of Pb, Cd, Zn, Ni, Cu, and Mn. The geo-accumulation index (I geo), enrichment factor (EF), and potential ecological-risk index (Er) were used to assess the level of soil pollution with heavy metals.Results The mean concentrations of Pb, Cd, Zn, Ni, Cu, and Mn were 355, 2.72, 347, 26, 36, and 505 mg/kg, respectively, which were higher than the background values of world soils. Based on the Igeo index, the study area was moderately to heavily contaminated with Pb and Zn, uncontaminated to moderate contaminated with Cd and Cu, and

This three-day symposium was organized by the US EPA, the USAF AL/EQ, Tyndall AFB FL, and the US AFCEE Technology Transfer Division, Brooks AFB TX. Natural attenuation, the biodegradation or chemical destruction or stabilization of contaminants, can reduce contaminants to levels protective of human health and ecosystems. The symposium was intended to increase understanding of the natural attenuation process and to review methods for screening sites and making decisions to determine the feasibility of natural attenuation at chlorinated solvent-contaminated sites. The symposium obtained feedback from the regulatory and industrial communities on the appropriate application of natural attenuation and the developing protocol for natural attenuation of chlorinated organics. The symposium featured invited platform presentations covering both laboratory studies and field demonstrations conducted in support of natural attenuation at government and industry sites.

Chemical analyses performed on the invasive weed Phytolacca americana (pokeweed) growing in industrially contaminated (Ulsan) and noncontaminated (Suwon) sites in South Korea indicated that the levels of phenolic compounds and various elements that include some heavy metals (Al, As, B, Cd, Co, Cu, Fe, Mn, Ni, Pb, and Zn) were statistically higher in Ulsan soils compared to Suwon soils with Al being the highest (|1,116 mg/l compared to 432 mg/l). Analysis of metals and nutrients (K, Na, Ca, Mg, Cl, NH4, N, P, S) in plant tissues indicated that accumulation occurred dominantly in plant leaves with Al levels being 33.8 times higher in Ulsan plants (PaU) compared to Suwon plants (PaS). The ability of PaU and PaS to tolerate stress was evaluated under controlled conditions by varying atmospheric CO2 and temperature and soil pH. When grown in pH 6.4 soils, the highest growth rate of PaU and PaS plants occurred...

Introduction Heavy metals are types of elements naturally present in soil or enter into soil as a result of human activities. The most important route of exposure to heavy metals is daily intake of food. Crops grown in contaminated soil (due to mining activities, industrial operations and agriculture) may contain high concentrations of heavy metals. Also closeness to cities and industrial centers can have a great influence on the accumulation of heavy metals to agricultural products grown in the region. The study aimed to determine the concentration of heavy metals in soil and agricultural products around urban and industrial areas of Zanjan province (North West of Iran) and consumption hazard probability. Materials And Methods Soil (75 samples of soil from a depth of 0 to 10 cm) and plant 101 samples) samples, in the summer 2011, were randomly taken from industrial areas as follow: tomatoes (Lycopersicum esculentum M), wheat seed (Triticum vulgare), barley seeds (Hordeum vulgare), alfalfa shoots
Soil and subsoil pollution is not only significant in terms of environmental loss, but also a matter of environmental and public health. Solid, liquid and gaseous residues are the major soil contamination agents. They originate from urban conglomerates and industrial areas in which it is impossible to emphasize the chemical, petrochemical and textile industry; thermoelectric, mining, and ironmaster activities. The contamination process can thus be defined as a compound addition to soil, from what qualitative and or quantitative manners can modify soils natural characteristics and use, producing baneful and deteriorative effects on human health. Studies have shown that human exposition to high concentration of some heavy metals found on soil can cause serious health problems, such as pulmonary or kidney complications, liver and nervous system harm, allergy, and the chronic exposition that leads to death. The present study searches for the correlation among soil contamination, done through a ...
This research project is a case study of the Asarco Tacoma smelter and the historical antecendents of widespread soil contamination in the Puget Sound region. From 1890 through 1985, Ruston, a small town near Tacoma, Washington, was home to one of the countrys most polluting smelters, which produced lead, copper, precious metals, arsenic trioxide, and sulfuric acid at various points during its operation. Owned by the American Smelting and Refining Company (Asarco), and primarily a copper smelter, the Tacoma smelter was unique for two reasons: it was able to process ore with high arsenic content; and it was located in an urban area. The environmental consequences of nearly a century of smelting include widespread arsenic, lead and other heavy metal soil contamination, contamination of sediments in Puget Sound, and arsenic slag, a by-product of smelting, dispersed throughout the region. The social consequences include: residents concerns about health, as awareness of potential exposure to toxins ...
Municipal Solid Waste (MSW), being a rich source of organic materials, can be used for agricultural applications as an important source of nutrients for soil and plants. This is also an alternative beneficial management practice for MSW generated in developing countries. In the present study, MSW treated soil samples from last four to six years at farmers field in Rohtak and Gurgaon states (Haryana, India) were collected. The samples were analyzed for all-important agricultural parameters and compared with the control untreated soil samples. The treated soil at farmers field showed increase in total N by 48 to 68%, P by 45.7 to 51.3%, and K by 60 to 67% compared to untreated soil samples. Application of sewage sludge at different sites led to increase in microbial biomass C by 60 to 68% compared to untreated soil. There was significant increase in total Cu, Cr, Ni, Fe, Pb, and Zn in all sewage sludge amended soil samples; however, concentration of all the metals were still below the current ...

Industrial contamination is one of the biggest concerns nowadays. The town of Mitrovica is located in the northern part of Kosovo, around 40 km north of the capital Pristina, with around 330 km2 and approximately 71,600 inhabitants, excluding the northern part of the city, in an altitude of about 500-550m. The town has the largest complex of mining and metallurgy in Europe -Trepça, known for exploitation of Pb, Zn and Cd, and, as a consequence, Mitrovica continues to be one of the most polluted cities in Kosovo as in air, soil and water. The anthropogenic source of heavy metals in the environment are either as a consequence of mining, smelting and aerosol deposition, or as an outcome of working on the soil such as the application of fertilizer (agriculturally induced), waste pollution via water and landfill sites. Mining is the largest anthropogenic source of heavy metal contamination. The purpose of this paper is to assess the soil pollution with heavy metals in Mitrovica towns surroundings and to
Concentrations of Al, Fe, Cr, Cu, Ni, Pb and Zn in soils, sediments and water samples collected along the Oued Boufekrane river (Meknes, central Morocco) were determined. In soils, a homogeneous distribution of metal concentrations was observed throughout the study area except for Pb, which presents high enrichment at sites located at the vicinity of a main highway. In sediments, high enrichment, with respect to upstream sites, were observed downstream of the city of Meknes for Al, Cr, Fe and Ni and inside the city for Cu, Zn and Pb. In water samples, the metal contents showed to correlate with their homologues in sediments suggesting that the metal contents in water and sediments have identical origins. Descriptive statistics and multivariate analysis (principal factor method, PFM) were used to assist the interpretation of elemental data. This allowed the determination of the correlations between the metals and the identification of three main factor loadings controlling the metal variability in soils

Heated Soil Vapor Extraction (HSVE) is a technology that has been used successfully to clean up subsurface soils at sites containing chlorinated solvents and petroleum hydrocarbons. The costs have been extremely high due to the large amount of energy required to volatilize high molecular weight polycyclic aromatic hydrocarbon (PAH) compounds present in the soil matrix. One remediation contractor states that hydrocarbons are oxidized in situ by achieving temperatures in the ,1000 F range near the heaters [1]. A critical question is whether the volatile portion of manufactured gas plant (MGP) hydrocarbons (VOCs) can be stripped out at lower temperatures such that the remaining contaminants will be unavailable for transport or subsequent dissolution into the groundwater. Soil remediation by heated soil vapor extraction system is a relatively new technology developed by Jay Jatkar Inc. (JJI) along with the University of Wisconsin-Milwaukee [2]. The areas around chemical companies or waste disposal ...

The presence of heavy metal contamination in soils is a global problem that prevents the development and use of significant amounts of industrial and agricultural land.
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous in the environment due to accidental spills during use, transport and storage of petroleum and coal derivatives. Their high chemical stability and hydrophobicity confers them recalcitrance. Because of their great persistence in the environment, toxicity and carcinogenicity, these compounds are on the list of priority pollutants. The most sustainable way to remove these compounds from soil without damaging its ecological structure and function is bioremediation. This technology uses the metabolic capabilities of microorganisms to decontaminate (degrade) polluted sites. Microorganisms act on the environment interconnected by metabolic networks, in which the byproducts generated by certain populations are utilized for others as a carbon source. Until recently, the PAH biodegradation studies were conducted by exposing individual compounds to pure strains. However, to improve the technology of bioremediation is necessary to unravel how these ...
Landfills are a common method of solid waste disposal. However, not many people are aware of the dangers posed by landfills and the toxic substances which are a substantial threat to the environment. Here are some facts about landfills which many people may not be aware of.
Landfills Infrastructure Essay, Research Paper THE LANDFILLS INFRASTRUCTURE What is the largest construction you can think of? Does a landfill come to your mind? Probably not. One of the largest buildings on the face of the earth is the Pyramid of the sun, constructed in Mexico and covers approximately thirty million cubic feet of space.
Picture 1: A serological pipette has been discarded in the regular trash. Even if the pipette was not contaminated with a biohazardous agent, it is considered a sharp because it can puncture the skin. Non-contaminated pipettes should only be discarded in the regular trash if properly packaged inside a puncture-resistant cardboard box. Picture 2: Serological pipettes have carelessly been thrown into a biowaste box sticking out in different directions. Biologically contaminated pipettes should always be discarded in a sharps container or a puncture-resistant carboard box before being deposited into a biowaste box. Non-contaminated plastic sleeves that could go in the regular trash have also been discarded in the biowaste box. In addition, biowaste boxes and containers should be closed when not in use.. Picture 3: An overpacked box is bulging and exposing the inner biohazard lining bag. Biowaste boxes should be properly closed in a way that the inner contents are not exposed to the outside. In ...

pH is the measurement of hydrogen ions in a substance; the lower the number of ions, the more acidic, and the higher the number of hydrogen ions, the more alkaline or basic. It is also the third primary factor used to identify the type of topsoil you have. Rainwater affects the pH of soil. Unpolluted rainwater has a normal pH of 6 to 6.5. The organic and mineral content of the topsoil play a part in the overall pH of the soil. The higher amount of rainfall will leach elemental ions from the soil leaving behind acidic combinations of hydrogen and aluminum. Sandy soil is typically high in minerals that combine with water to form acids because it lacks organic content. Loam top soil stays close to a pH level of 7, which is considered neutral, because of the balance of organic matter and mineral content (acids and bases will neutralize each other). Clay soil is more likely to become alkaline because the minerals that make up the basic structure of clay form bases when mixed with water (ammonia and ...
EcoLox Blue Pond & Lake Dye is distinctly different from all other pond and lake colorants and aquatic plant growth inhibitors on the market today because EcoLox has recently acquired exclusive rights to a unique formula of Acid Blue 9, developed by Annulox, LLC. With the development of AnnuLox®, a proprietary oxidation catalyst, we are able to eliminate heavy metal toxicants and environmental pollutants (primarily chromium, lead and manganese) commonly found in traditional Acid Blue 9 dye manufacturing processes. While these pollutants may not be present in measurable amounts in our competitors pond and lake dye formulas, they are produced in massive quantities as a by-product of the Acid Blue 9 dye manufacturing process. Through the use of this unique, proprietary manufacturing process, EcoLox Blue Pond & Lake Dye can conceivably reduce heavy metal contamination of the earth and its waterways by thousands of metric tons per year.. ...

Eggs have been found to be sensitive indicators of persistent organic pollutant (POP) contamination in soils or dust and are an important exposure pathway from soil pollution to humans, and eggs from contaminated areas can readily lead to exposures with exceeding thresholds for the protection of human health (Van Eijkeren, Zeilmaker et al. 2006, Hoogenboom, ten Dam et al. 2014, Piskorska-Pliszczynska, Mikolajczyk et al. 2014). Chickens and eggs might therefore be ideal active samplers and indicator species for evaluation of the level of contamination of sampled areas by POPs, particularly by dioxins (PCDD/Fs) and PCBs. Based on this assumption, we have chosen sampling of free range chicken eggs and their analyses for selected POPs as one of the monitoring tools within the project Strengthening the capacity of pollution victims and civil society organizations to increase chemical safety in China.. The data and analyses of free range chicken eggs discussed in this report were obtained during ...
Fapas, the proficiency testing arm of Fera, has introduced a new proficiency test for the control of heavy metal contamination in mussels.
Were not sure ourselves! To achieve organic status in Australia skin care products just have to have 70% organic content. Explain that one! Thats like eating an apple thats 70% organic... it makes no sense to us and we think the certification is weak and is used for marketing purposes. Our herbs are medicinal grade which means one thing only - of a standard, grade and efficacy that can be used to make remedies for prescription by Herbalists. Plant extracts in most products are also invariably weak (certified organic doesnt mean effective); the amount used can be so very tiny - to say it is a drop in a bucket would be being generous. This wont give positive, lasting results for skin. David has been sent samples of organically grown herbs and he always has these analyzed. They usually are organic as claimed; free of pesticides, herbicides and heavy metal contamination but they often are very low in what are called active principles ie the constituents that make the herb work! ...

A transfer station in waste terminology is a location that facilitates the transport of refuse (trash disposed of in the black bins). Our transfer station serves to temporarily store refuse collected throughout the City before a larger truck is ready to pick it up and transport it for the long haul to the nearest landfill. As the Citys own landfills are all closed, the destinations are private landfills. In 2004, the City of Los Angeles purchased Central L.A. Recycling & Transfer Station (CLARTS). As the recycling operations that were previously done at the facility have ceased, the City continues to operate the facility as a transfer station. Learn more about transfer stations and their operations.. ...
