Health: If you eat fish grown in dirty water, then there may be chances of cancer and brain stroke, read this research..
Freshwater Fish Have High Levels Of Chemicals: If you are fond of eating non-vegetarian food, especially fish, then this news may disturb you a bit. In fact, according to a report published in the Environmental Working Group (EWG), freshwater fish can prove to be harmful to health. It was revealed in this report that a special type of chemical is being found in freshwater fish, especially largemouth bass, lake trout, or catfish. Which is called perfluorooctane sulfonic acid (PFOS). This chemical is being found 278 times in freshwater fish. This chemical is so dangerous that it can cause cancer as well as many other serious diseases.
The environmental working group presented the report
According to the report of the Environmental Working Group (EWG), if the fish found in sweet lakes and ponds of America is eaten, then one fish can be equal to a month's dirty water. This dirty water can be equivalent to water contaminated with PFOS. This is equivalent to 48 times the average in a trillion.
US Environmental Protection Agency
Data collected by the US Environmental Protection Agency (EPA) found that the average amount of PFOS and other chemicals classified as PFAS is. Perfluorinated alkylated substances were 280 times more chemical in freshwater fish than in commercially caught fish.
Rensselaer Polytechnic Institute in New York
Dr Kevin C. Rose, an associate professor of biological sciences at Rensselaer Polytechnic Institute in New York, told Healthline that top saltwater fish are finding high levels of the chemical in freshwater fish like pike, trout and bass.
High levels of mercury are also found in saltwater fish, especially swordfish and tuna.
There are many dangerous chemicals in freshwater fish.
The research in the US included data from more than 500 samples from the EPA, the National River and Streams Assessment, and the Great Lakes Human Health Fish Fillet Tissue Study and Program from 2013 to 2015.
The average level of total PFAS in fish fillets was 9,500 nanograms per kilogram, with an average level of 11,800 nanograms per kilogram in the Great Lakes.
What is forever chemical
Per-and-polyfluoroalkyl substances (PFAS) are found in freshwater fish. This is the chemical that is on nonstick or water-resistant clothes. For example, it is on the cover of a raincoat, umbrella or mobile. This chemical is also found in shampoo, nail polish and eye makeup. This has been clearly stated in many types of research.
Why this forever chemical is considered dangerous for humans
This chemical is considered dangerous for humans because it has a direct effect on human growth and hormones. Because of this the risk of thyroid and cholesterol increases. The risk of a miscarriage in pregnant women increases. Children's body also affects growth. Along with this, the risk of brain stroke also increases. In 2017, the International Agency for Research on Cancer declared PFOA a clear human carcinogen – these chemicals increase the risk of cancer and kidney and testis cancer.
