The PVC membrane of an ion-selective electrode (ISE) sensitive to dibasic phosphate ions (HPO4-ISE) has not been optimized for maximum selectivity, sensitivity, and useable ISE lifetime and further work was necessary to improve its performance. Two areas of investigation are reported here: include the parameters for the lipophilicity of the plasticizer compound used and the amount of cyclic polyamine ionophore incorporated in the PVC membrane. Six candidate plasticizers with a range of lipophilicity were evaluated for their effect on the useable lifetime, sensitivity, and selectivity of the ISE against 13 different anions. Selectivity was determined by a modified fixed interferent method, sensitivity was determined without interferents, and the usable lifetime evaluated at the elapsed time where 50% of the HPO4-ISE failed (L50). The results show that choosing a plasticizer that has a lipophilicity similar to the ionophores results in the best selectivity and sensitivity and the longest L50.

Plasticizers (UK: plasticisers) or dispersants are additives that increase the plasticity or decrease the viscosity of a material. These are the substances which are added in order to alter their physical properties. These are either liquids with low volatility or may be even solids. They decrease the attraction between polymer chains to make them more flexible. Over the last 60 years more than 30,000 different substances have been evaluated for their plasticizing properties. Of these, only a small number - approximately 50 - are today in commercial use. The dominant applications are for plastics, especially polyvinyl chloride (PVC). The properties of other materials are also improved when blended with plasticizers including concrete, clays, and related products. According to 2014 data, the total global market for plasticizers was 8.4 million metric tonnes including 1.3 million metric tonnes in Europe. Plasticizers for plastics are additives, most commonly phthalate esters in PVC applications. ...

Phthalates are ubiquitous, carcinogenic estrogenic chemicals that contaminate food, indoor air, soil, sediment and drinking water. They are added to plastics to make them soft, to polyvinyl chloride (PVC) products to impart flexibility and durability, to cosmetics and conditioner to make them sticky, and are used in childrens toys, food containers and wraps, and medical devices, including IV bags and tubing. They are present as micropollutants in many rivers and contaminate drinking water. The ozone/UV process efficiently eliminates them from water sources. Some of the phthalates contribute to breast cancer risk by inhibiting an enzyme called sulfotransferase, which prevents inactivation of estrogen, particularly in the liver, by a detoxification process called sulfation. Estrogen levels may be higher when we are exposed to phthalates present in food containers, water and juice bottles, cosmetics and drinking water. Phthalates mimic estrogen and are capable of binding to the estrogen receptor, ...

The increasing use of plastic materials has modified several aspects of design and management of water distribution systems. With reference to the numerical modeling of transients, the definition of a correct rheological model of the pipe material is receiving an increasing interest. In this paper the behavior of the molecularly oriented polyvinyl chloride (PVC-O) pipes during transients is investigated, by means of tests on a PN16 DN110 pipe installed at the Water Engineering Laboratory of the University of Perugia, Italy. Pipe characteristics, such as wave speed and Kelvin-Voigt parameters, are estimated by the comparison of experimental and numerical results. Analyses are performed both in time and frequency domain. The variation in time of the wave speed is investigated. The results show that, while the wave speed value is close to that of other polymeric material pipes, such as Polyethylene, the viscoelastic behavior is less evident for PVC-O pipes. This feature is of particular interest ...

MAIN CONCLUSION - Banning the use of chlorine chemistry in the manufacture of only three of the major uses of chlorine (steel, Polyvinyl Chloride (PVC) and Titanium Dioxide) would result in a requirement to landfill an additional 24.6 billion pounds of waste each year (4.2 billion pounds auto related), raise serious issues regarding recycling with regard to PVC substitutes and raise the cost of related parts by some $2.0 billion a year. In addition, the use of available substitutes for chlorine-based compounds would result in a serious degradation in the quality and performance of automobiles manufactured in North America.PROCESS - Essentially, the process consisted of a micro economic analysis of the impact on the cost and performance of a representative automobile manufactured in North America and the differential environmental impact arising from the use of available substitutes.This entailed breaking the representative car down into its major systems, subsystems and 12,500 components to ...

Nuclear power plants generate a significant part of the worlds electrical power consumption. However, many plants are nearing the end of their designed lifetime, and to extend the lifetime it is important to verify that every component can withstand the added service time. This includes polymeric materials, which become brittle with time. By predicting their lifetime and monitoring their condition, unnecessary downtime of the plant can be avoided, and secure operation can be ensured. The lifetime can be predicted by extrapolating results from accelerated ageing to service conditions, or by simulation of the degradation process.. In this study, lifetime predictions through extrapolation were performed on samples of a polyvinyl chloride (PVC) core insulation and an acrylonitrile butadiene rubber (NBR) membrane, which were thermally aged in air. The lifetime of the PVC cable was predicted using Arrhenius extrapolation, and using a method based on Langmuir, Clausius-Clapeyron, and Kirchhoffs ...

TY - JOUR. T1 - XRCC1, CYP2E1 and ALDH2 genetic polymorphisms and sister chromatid exchange frequency alterations amongst vinyl chloride monomer-exposed polyvinyl chloride workers. AU - Wong, Ruey Hong. AU - Wang, Jung Der. AU - Hsieh, Ling Ling. AU - Cheng, Tsun Jen. PY - 2003/8/1. Y1 - 2003/8/1. N2 - Vinyl chloride monomer (VCM) is a known human carcinogen, which may be metabolized by cytochrome P450 2E1 (CYP2E1), aldehyde dehydrogenase 2 (ALDH2), and glutathione S-transferase T1 (GSTT1). A DNA-repair gene, X-ray repair cross-complementing group 1 (XRCC1, exon 10), may also be implicated in the process of VCM-related carcinogenesis. Thus, VCM-exposed workers with inherited susceptible metabolic and DNA-repair genotypes may experience an increased risk of genotoxiciy. This study was designed to investigate whether metabolic and DNA-repair genotypes affected sister chromatid exchange (SCE) frequency in occupationally VCM-exposed workers from polyvinyl chloride (PVC) manufacturing plants.

Immunoglobulin E (IgE), directed against components of Acacia (wattle) pollen, has been detected by (RAST) in the sera of some children and adults who develop allergic symptoms in the presence of flowering Acacia trees in Australia. All these subjects also had high levels of IgE directed against Lolium perenne (rye grass) pollen. Inhibition by RAST showed that most of the IgE molecules which bound to Acacia pollen components also bound to L. perenne pollen extracts, and to Glycoprotein 1, the major allergen of L. perenne pollen. In these assays, the allergens have been immobilized on polyvinyl chloride microtitre trays: the sensitivity of this approach is compared to that of commercial RAST kits [3]. Sensitization to gum arabic carbohydrate structures occurs casually in atopic patients with pollen sensitization without obvious exposure to gum arabic. According to the study of Sander I, et al (2006) allergy to gum arabic is mediated preferentially by IgE antibodies directed to polypeptide chains ...

OxyChems affiliate OxyVinyls, LP is the worlds largest Vinyl chloride monomer (VCM) producer.. Vinyl chloride monomer (VCM) is the key chemical precursor to PVC. It is produced commercially by combining a hydrocarbon feedstock, namely ethylene, obtained by cracking natural gas or petroleum, with elemental chlorine.. Chlorine is derived from brine - a solution of common salt and water. Since both raw materials are inexpensive, readily available commodities, PVC is less sensitive to fluctuations in the world oil market compared to other polymers. Chlorine also has excellent inherent flame-retardant properties that are directly passed on to vinyl end-products, such as electrical conduit and wiring, which require high resistance to flame.. OxyVinyls offers VCM as a commodity sold in large, commercial quantities for PVC manufacturing. ...

Many chemicals used in the electronics sector have negative consequences for human and environmental health. These include chemicals such as lead, mercury, brominated flame retardants, halogenated flame retardants, polyvinyl chloride (PVC) and phthalates. Typical electronic waste handling practices in developing countries are detrimental to the health of workers, their environment, and their communities. There are issues associated also with formal recycling in modern facilities, and the production phase is often problematic as well, with electronics workers potentially being exposed to carcinogens and reproductive toxicants. In addition, it is becoming apparent that recycling of valuable materials must be made more efficient as the price of virgin materials, metals, and minerals increases and their availability decreases. The problems are exacerbated by the fact that there has been a rapid increase in sales of electronics in the past several years, making e-waste one of the fastest-growing waste

Care has to be taken in handling and storing VCM. Mostly because it is a highly flammable and potentially explosive gas (like the lighter fuel butane). But also because, if breathed in quantity, it is a strong narcotic (like chloroform). In fact, during the 1950s VCM was trialled as a potential anaesthetic gas for medical applications. However, studies conducted during the 1970s on workers in PVC polymerisation plants revealed that VCM is a carcinogen, and significant exposure over a prolonged period can cause a rare form of cancer, known as angiosarcoma (cancer of liver blood vessels), if there is significant exposure over a prolonged period. Once industry discovered this link, major action was taken to reduce levels of exposure amongst industry personnel.. All manufacturing processes involving the use of VCM today are closed, and all personal exposure is avoided and closely monitored. Workers are regularly tested for even the lowest levels of exposure and there have been no incidences of ...

South Africa. Most feeding tubes today are made of polyurethane or silicone. These materials have tended to replace the older polyvinylchloride feeding tubes that tend to stiffen when exposed to digestive juices and are more irritating to patients, necessitating frequent tube replacement. Silicone is softer and more flexible than other tube materials with a greater tendency to stretch and collapse. Polyurethane is stronger than silicone, allowing for a tube of this material to have thinner walls and thus a larger internal diameter, despite the same French size. The flexibility and decreased internal diameter of silicone tubes may lead to clogging or kinking of the tube. Both polyurethane and silicone do not rapidly disintegrate or embrittle in situ, providing a longer wear . The French (F) unit measures the outer lumen diameter of a tube (each French unit is equal to 0.33 mm). Tubes that are too flexible may be chilled before placement to increase stiffness. Nasoesophageal. Simple and efficient ...

With global production of plastic exceeding 280 metric tons every year, a fair amount of the stuff is bound to make its way to the natural environment. However, until now researchers havent known whether ingested plastic transfers chemical additives or pollutants to wildlife. A new study conducted by an NCEAS researcher shows that toxic concentrations of pollutants and additives enter the tissue of animals that have eaten microplastic. The findings are published today in Current Biology.. There were two primary objectives for the study: to look at whether chemicals from microplastic move into the tissues of organisms; and to determine any impacts on the health and the functions that sustain biodiversity. Lab experiments exposed lugworms (Arenicola marina) to sand with 5 percent microplastic (polyvinylchloride) that also contained common chemical pollutants (nonylphenol, phenanthrene) and additives (Triclosan, PBDE-47). Results showed that pollutants and additives from ingested microplastic were ...
