Shuanghui apologized on its website and said it discontinued partnerships with producers using the contaminant.
For example, contaminant removal may include the separation of unwanted materials like electronics, PVC and minerals.
The difference is that plastics with their accumulated contaminant load are directly ingestible by organisms.

Environmentalists argue that fracking is a serious groundwater contaminant, a claim supported last week by leading Democrats.

Given the potential for the accidental introduction of contaminant DNA into this experiment, the conclusions cannot be safely generalised.
FORBES: Big Study Linking Chronic Fatigue To Virus May Be Fatally Flawed
The norovirus is the most common food contaminant that makes people sick, with symptoms including diarrhea, vomiting and nausea.

Chloride, considered a secondary contaminant, could affect drinking water's taste, smell and color.
The association between XMRV and mouse DNA in this study is imperfect whereas in a contaminant scenario it would not be.
FORBES: Big Study Linking Chronic Fatigue To Virus May Be Fatally Flawed
So, anything when it comes to in the disease area or any type of contaminant both in healthcare and also industrial.
But when the instruments were flushed out and new samples tested, the methane all but disappeared just a contaminant brought over from Earth.
Microplastics have larger surface to volume ratios, potentially facilitating contaminant exchange and have been shown to be ingested by a range of organisms.

Since joining Abertay, Dr Farrugia has written a set of guidelines that explain which technique should be used for which contaminant, on which type of material.

Milk samples from Phoenix and Los Angeles contained iodine-131 at levels roughly equal to the maximum contaminant level permitted by EPA in drinking water, the data shows.
FORBES: Radiation Detected In Drinking Water In 13 More US Cities, Cesium-137 In Vermont Milk
This method can let the team know whether the contaminant-degrading microbes are healthy and growing, or, under some types of stress, possibly signal the need for more active remediation efforts at a site.
One of the greatest uncertainties is whether this leads to the bioaccumulation of the contaminant load (absorbed and plastic additives), and hence whether micro-plastics represent an additional and significant vector for transferring pollutants.

The EPA maximum contaminant level is 3.0, but this is a conservative standard designed to minimize exposure over a lifetime, so EPA does not consider these levels to pose a health threat.

An environmental remediation team could use qPCR to count the population of specific contaminant degrading microbes, or to assess the genetic biochemical pathways (e.g. microbial cellular machinery) that cause the degradation of environmental contaminants.
Mixing it up reduces the chances that you are getting too much of a single contaminant, he says, adding that the lower one eats on the food chain, the less of an impact one has.
Since data from some homes showed elevated contaminant levels and several residents expressed concern, EPA determined that well sampling was necessary to gather additional data and evaluate whether those residents had access to safe drinking water.

In my opinion, the best solution would be to go with a brand that carries the seal of USP or NSF, two nonprofit organizations that certify that vitamins are contaminant free and made according to good manufacturing practices.
Because of the indirect mechanism of its toxicity and its specificity for human cells, the contaminant had been undetectable in both the standard, sophisticated screening tests that are supposed to assure a drug's purity and quality, and in studies in animals.
