"Levels of ‘forever chemicals’ in North Atlantic pilot whales have declined by more than 60% due to greater regulations, according to new research from Harvard.

PFAs chemicals are ubiquitous in modern life. First produced at the end of World War II, they are found in everything from furniture and cosmetics, to food packaging, non-stick pans and clothing. They take thousands of years to degrade naturally, and have infiltrated into our water, soil and food – making them a major concern for human and ecological health. 

The damage of PFAs chemicals have been well-documented. From disrupting seabirds’ energy production and reproductive success, to weakening immunity in sea otters, and being associated with serious health implications, like liver and kidney disease in humans."
