‘Eating a wild fish like month of drinking tainted water’

Researchers say the US study provides the first evidence for widespread transfer of PFAS chemicals directly from fish to humans

New research says that eating one freshwater fish caught in a river or lake in the United States is the equivalent of drinking a month's worth of water contaminated with toxic chemicals

Eating one freshwater fish caught in a river or lake in the United States is the equivalent of drinking a month’s worth of water contaminated with toxic “forever chemicals”, new research said on Tuesday.

The invisible chemicals called PFAS were first developed in the 1940s to resist water and heat, and are now used in items such as non-stick pans, textiles, fire-suppression foams and food packaging.

Pollutants everywhere

But the indestructibility of PFAS, per- and polyfluoroalkyl substances, means the pollutants have built up over time in the air, soil, lakes, rivers, food, drinking water and even our bodies.

There have been growing calls for stricter regulation for PFAS, which have been linked to a range of serious health issues including liver damage, high cholesterol, reduced immune responses and several kinds of cancer.

To find out PFAS contamination in locally caught fish, a team of researchers analysed more than 500 samples from rivers and lakes across the United States between 2013 and 2015.

The median level of PFAS in the fish was 9,500 nanogrammes per kilogramme, according to a new study published in the journal Environmental Research.

Nearly three quarters of the detected “forever chemicals” was PFOS, one of the most common and hazardous of the thousands of PFAS.

Eating just one freshwater fish equalled drinking water with PFOS at 48 parts per trillion for a month, the researchers calculated.

Last year the US Environmental Protection Agency lowered the level of PFOS in drinking water it considers safe to 0.02 parts per trillion.

The total PFAS level in the freshwater fish was 278 times higher than what has been found in commercially sold fish, the study said.

‘Greatest chemical threat’

David Andrews, a senior scientist at the non-profit Environmental Working Group which led research, told AFP he grew up catching and eating fish. “I can no longer look at a fish without thinking about PFAS contamination,” said Andrews, one of the study’s authors.

The findings were “particularly concerning due to the impact on disadvantaged communities that consume fish as a source protein or for social or cultural reasons,” he added.

“This research makes me incredibly angry because companies that made and used PFAS contaminated the globe and have not been held responsible.”

Patrick Byrne, an environmental pollution researcher at the UK’s Liverpool John Moores University not involved in the research, said PFAS are “probably the greatest chemical threat the human race is facing in the 21st century”.

“This study is important because it provides the first evidence for widespread transfer of PFAS directly from fish to humans,” he told AFP.

Andrews called for much more stringent regulation to bring an end to all non-essential uses of PFAS.

The study comes after Denmark, Germany, the Netherlands, Norway and Sweden submitted a proposal to ban PFAS to the EU’s European Chemicals Agency on Friday.

The proposal, “one of the broadest in the EU’s history,” comes after the five countries found that PFAS were not adequately controlled, and bloc-wide regulation was needed, the agency said in a statement.

  1. Thank you so will not eat fish, but vegetables have pesticides so what is safe to eat only option it seems is to grow your own vegetables as pesticides free vegetables seller could lie.

CPR or cardiopulmonary resuscitation is an emergency lifesaving procedure performed when the heart stops beating. According to American Heart Association, immediate CPR can double or triple chances of survival after cardiac arrest. Keeping the blood flow active, even partially, extends the opportunity for a successful resuscitation once trained medical staff arrive on site. It is an important lifesaving first-aid tool that can be performed by anyone.
