The Colombia Environment Agency issued its first fish consultation based on the presence of PFAS or “forever chemicals” in a fish caught in the rivers passing through the nation’s capital. The consultative warns people who eat fish caught by the portions of the Potomak and Anacosty rivers in the field to consider eating less or none of the certain fish.
Issued in December, consultations are based on fish tissue studies conducted by the Ministry of Energy and the Environment of the District. For the first time, these studies have been tested for the presence of per- and polyfluoroalling substances or PFAS, in addition to the search for PCB (polychlorinated biphenyls), PAH (polycyclic aromatic hydrocarbons), metals and certain pesticides. PCBS are also considered a “chemical of concern” in the fish tissues taken from the same water bodies.
The group of synthetic substances known as PFAS are called chemicals forever because they do not fall apart in the environment. Instead, like other chemicals that can be toxic to both humans and the environment, they tend to accumulate over time. Long -term PFAS exposure, including by consuming foods containing chemicals, can pose health risks such as cancer, liver problems and reduced immunity.
For decades, PFA has been widely used in various industrial and consumer products, from fire foam to non -stick cookware, which makes it difficult to track and address the sources of pollution in surface water.
The US Environmental Protection Agency publishes project criteria to limit certain PFAs in waters that maintain water life but still have no final standards.
It is better to understand how too much it is when it comes to widespread chemicals. Although federal drinking water standards have been issued for PFA, the process of determining the standards for fish consumption can be even more complicated.
The Ministry of Energy and the Environment said her PFAS notice was “in advance” as the EPA has not yet issued its final guidelines “How to Interpret” PFAS concentrations in fish tissue.
Fish consumption warnings do not relate to fish purchased from restaurants, supermarkets or fish sellers in the city.
So far, the agency advises the general public not to eat eel, carp, striped bass or Largemut bass from every waterway of DC; to limit the consumption of blue catfish to three servings per month; And to have no more than one serving per month brown catfish, canal catfish, Gizzard Shad, Smallmouth Bass, Snakehead, Sunfish, white perch and yellow perch.
