Microplastic particles are increasingly being discovered in diverse habitats and a host of species are found to ingest them. (researchgate.net)
While previous work has shown that microplastics were up to 10 times higher in the feces of babies compared with adults, and that infants fed with plastic bottles are swallowing millions of microplastic particles each day, the common assumption was that adults are less exposed to these dangerous pollutants. (earth.com)

However, fiber cement siding when cut can create fine dust particles containing silica that when breathed in, can lead to serious lung diseases, such as silicosis . (cdc.gov)
The only published study on fiber cement cutting suggests that the fine dust particles result in high concentrations of silica exposure, putting workers at risk for silicosis [i] . (cdc.gov)
We then cut the siding in an isolated chamber in our laboratory and found that many of the generated dust particles are small enough to reach the deepest part of the lung. (cdc.gov)

The observed changes can be interpreted as indications that the degradation processes in the bumblebees' organism are promoted by the degradation particles ingested with food over a longer period of time, while processes of biosynthesis are slowed down. (uni-bayreuth.de)

Study co-author Neil Loneragan, a professor at Murdoch University, said that it is difficult to assess exactly how many plastic particles are actually ingested by manta rays and whale sharks because conventional methods of studying animal diets, like stomach analysis, aren't feasible for threatened species like these.

Most scary - since I drink only bottled water - is that I may be ingesting an additional 90,000 particles annually, compared to 4,000 microplastics for those who only drink tap water (Cox et al. (saturdayeveningpost.com)
People who drink exclusively from plastic water bottles ingest an additional 90,000 microplastics each year, researchers found. (smithsonianmag.com)
The study authors found that people who drink exclusively from plastic water bottles ingest an additional 90,000 microplastics each year, compared to 4,000 among those who only consume tap water. (smithsonianmag.com)

Humans also ingest microplastics via food: they have already been detected not only in fish and seafood, but also in salt, sugar and beer. (sciencedaily.com)
Based on this data, the researchers calculated that our annual consumption of microplastics via food and drink ranges between 39,000 and 52,000 particles, depending on age and sex. (smithsonianmag.com)

Therefore, these results support the conclusion that in most cases the transfer of organic pollutants to aquatic organisms from microplastic in the diet is likely a small contribution compared to other natural pathways of exposure. (researchgate.net)
Further research is needed to assess the short- and long-term effects of exposure to these particles, and to urgently find ways of limiting plastic pollution, before it turns into a huge public health hazard. (earth.com)

Communities on the fenceline of petrochemical and plastics infrastructure face chemical pollution of air, land, and water, in addition to pollution of dangerous plastic particles, noise, and risk of deadly industrial accidents like fires and explosions. (plasticpollutioncoalition.org)
As plastics are ingested up the food chain, these chemicals accumulate, causing problems for marine predators and potentially humans. (oceanconservancy.org)
Most plastics aren't degradable and only a small proportion is recyclable - plastics are slowly broken down into smaller particles, called microplastics. (studiorepublic.com)
That means that plastics are being ingested by the filter feeders, which are thus likely being exposed to toxic chemicals and pollutants while the plastics are in their digestive systems. (mongabay.com)
Measuring less than five millimeters in length, microplastics derive from a variety of sources , including large plastics that break down into smaller and smaller pieces. (smithsonianmag.com)

And then it would be a matter of understanding exactly what risk the tiny plastic particles -some of which differ considerably in their chemical composition -pose to humans and the environment, in other words: how dangerous they ultimately are. (phys.org)
It's hardly surprising, then, that the tiny fragments have also been found in humans . (smithsonianmag.com)
These new properties may cause a problem if nanoparticles are unintentionally released - very few of these particles exist in nature and we as humans have not been exposed to them throughout evolution. (lu.se)

Additionally, microplastics, which are plastic particles smaller than 5 mm, can be ingested by marine fauna and accumulate in the food chain. (dominicantoday.com)
Unfortunately, these microplastics remain with the food and accumulate in these animals' stomachs. (nmlc.org)
When tiny, tiny plastic particles accumulate in our lakes, they are absorbed by phytoplankton and zooplankton. (lu.se)

Tiny zooplankton can also mistake very small plastic particles for food and ingest them either accidentally or by chance (when the particles have combined with organic particles). (geomar.de)
That means that manta rays and whale sharks are also at risk of accidentally ingesting tiny pieces of plastic known as microplastics (which are typically said to be less than 5 millimeters in length), the result of plastic bags, single-use packaging, and other plastic waste making its way into the ocean and breaking down over time. (mongabay.com)

Researchers from IGB have demonstrated in earlier studies that microplastics might be harmful to ecosystems when ingested by aquatic key organisms. (sciencedaily.com)
They say the miniscule spheres could harm aquatic animals that mistake them for food. (acs.org)
After entering waterways, these particles can be absorbed by aquatic flora and ingested by aquatic fauna - they have been detected in creatures from plankton and fish right through to whales. (ifamagazine.com)

Bad smells arise when to much food (more than the worms can eat) is allowed to rot and becomes Anaerobic (bacteria that doesn't need oxygen to live). (wormcity.co.uk)
The blood-brain barrier or placenta, for instance, prevents particles and macromolecules from passing through until they reach a certain size-or rather, smallness-thereby protecting the tissues and organs "behind" them, i.e. the brain and fetus, respectively, from potentially dangerous substances such as viruses and bacteria.

The direct effects of such microplastic ingestion on zooplankton are poorly understood, but the broader effects on ecosystems of zooplankton replacing some of their food with plastic are much less well understood. (geomar.de)
Now, for the first time, a research team has used an Earth system model to simulate how zooplankton that ingest microplastics could affect the base of the ocean food web and nutrient cycling. (geomar.de)
These findings are significant because there has long been scepticism in the scientific community that microplastic concentrations in the ocean are high enough to have any impact on nutrient cycling", says Dr Karin Kvale "Our study shows that even at levels present in the ocean today, it may already be the case if zooplankton replace some of their natural food with microplastics. (geomar.de)
If zooplankton eat the microplastics and thus take up less food, this can have far-reaching ecological effects that can, for example, lead to increased algal blooms via a reduction in feeding pressure that affect the oxygen content of the oceans almost as much as climate change", Kvale continues. (geomar.de)
Due to their filter feeding strategy, manta rays and whale sharks must swallow hundreds to thousands of cubic meters of sea water every day in order to catch enough zooplankton, microscopic organisms that float passively in the water and are an important source of food for the filter feeders. (mongabay.com)
Studies have found that even the smallest marine organisms, zooplankton, are able to ingest these particles and pass them up the food chain due to the fact that they cannot be digested. (nmlc.org)
Food-web contamination may begin with MP ingestion by zooplankton, which is the primary consumer, and constitute the lowest heterotrophic trophic level of many ecosystems (e.g. (frontiersin.org)

Half of these samples contained PET plastic (commonly used in drinks bottles), a third of them contained polystyrene (used for packaging foods and various other products), and a quarter contained polyethylene (from which plastic carrier bags are manufactured). (earth.com)
When it erodes, you may notice that you react more to hot or cold foods, drinks, and sweets, since they can get through holes in your enamel to the nerves inside. (webmd.com)

Approximately 45% of ingested Po-210 is deposited in the spleen, kidneys, and liver; 10% is deposited in the bone marrow and the remainder is distributed throughout the body. (cdc.gov)
In general, approximately 30-50% of lead ingested by children is absorbed, compared with approximately 10% of that ingested by adults. (medscape.com)

There's no denying that tobacco product waste produces massive plastic pollution causing irreparable damage to our environment, our food supply, and our bodies. (sacobserver.com)
However, Kvale points out that the results are "very preliminary" because little is yet known about how the base of the food web interacts with microplastic pollution. (geomar.de)

Then you slowly start adding your food waste. (wormcity.co.uk)
In the water, the plastic slowly breaks down into smaller and smaller particles. (lu.se)

An even more serious peril to animal and human health occurs as plastic disintegrates, breaking down into small pieces no bigger than a raisin. (marinefm.org)

Ingesting large doses of antimony can cause vomiting. (cdc.gov)
A potential explanation for the lack of correlation with childhood asthma is the large mass of the particles, preventing them from reaching the lower airways. (who.int)

Malathion is not widely dispersed or persistent in the environment, but is detected frequently in foods. (cdc.gov)
Malathion has been released to the environment mainly as a result of its use as an insecticide on food and feed crops, noncrop agricultural use, home and garden use, and public health use (for medfly and mosquito control). (cdc.gov)
It is applied in the environment mainly by aerial, ground spraying, or fogging equipment, but is also used in bait type formulations (i.e., applied to food baits). (cdc.gov)
The things in nano technology that might pose a risk to us or to the environment are related to the fact that we need to make sure that we handle these new particles and materials in a safe way. (lu.se)

An integrated methodology for assessing the impact of food matrix and gastrointestinal effects on the biokinetics and cellular toxicity of ingested engineered nanomaterials. (bvsalud.org)
To assess potential hazards , efficient in vitro methodologies are needed to evaluate particle biokinetics and toxicity . (bvsalud.org)
An in vitro transwell triculture epithelial model was used to assess biokinetics and toxicity of ingested Fe2O3 ENM. (bvsalud.org)
The importance of food matrix and GIT effects on biointeractions was demonstrated, as well as the incorporation of these critical factors into a cellular toxicity screening model. (bvsalud.org)

Hoping to fill in some of these gaps, a research team led by Kieran Cox , a PhD candidate at the University of Victoria and a former Link Fellow at the Smithsonian Institute, looked at 26 papers assessing the amount of microplastics in commonly consumed food items, among them seafood, sugars, salts, honey, alcohol and water. (smithsonianmag.com)
serum , respectively, suggesting that use of serum proteins alters iENMs biokinetics and raises concerns about commonly-used approaches that neglect iENM - food -GIT interactions or dilute digestae in serum -containing media. (bvsalud.org)

In another study, the focus was on how the particles affect the insects' immune system. (uni-bayreuth.de)
