Over 300 wildlife species showed traces of the nearly indestructible synthetic chemicals, according to a report from the Environmental Working Group's (EWG) PFAS Project Lab.
The mapping of over 125 peer-reviewed scientific studies is the first global scoping of the problem in wildlife, the authors said.
An in-depth investigation in Europe, where more data is available than in other parts of the world, on Thursday revealed so-called perfluoroalkyl and polyfluoroalkyl substances (PFAS) in 17,000 sites across the continent.
More than 2,000 are classified as hazardous to human health.
"No matter the country or continent, if species are tested for PFAS contamination, these harmful chemicals show up," said the EWG.
The report estimated that PFAS place a burden of tens of millions of euros on European health systems each year.
Blank spots on the global map -- notably in Africa and South America -- are likely due to a lack of data, according to the report.
Non-degradable repellent PFAS, also known as "forever chemicals", were introduced in the 1940s. The best known is the Teflon used for non-stick cookware.
Persistent chemicals pollution is present in air, water and soil, and has been shown to pose health risks -- including cancer -- to humans.
The European survey was the result of a months-long investigation by 18 European newsrooms collectively called "The Forever Pollution Project."

Their analysis concluded that Europe is far more contaminated by PFAS than previously understood, and that it will cost tens of billions of euros (dollars) to rid nature of these hazardous chemicals.
"They don't degrade in the environment and are very mobile, so they can be detected in water, air, rain, otters and cod, boiled eggs and human beings," the researchers said.
Their investigation found 20 producers of PFAS in Europe and 232 industrial manufacturers -- predominantly in Germany -- where PFAS turned up in plastics, pesticides and water-proof textiles.
The map also reveals over 2,100 "hotspots" where the concentration of PSAS reached the more than 100 nanograms per litre of water -- the health hazard threshold for human health.
Some "forever chemicals" are known to cause cancer and reproductive problems, but little is known about their combined effect.
A study published Wednesday in Environmental Health Perspectives found that exposure to multiple PFAS found in the environment can lead to developmental disorders, cardiovascular disease and many types of cancer.
"Most people carry a mixture of the chemicals in their blood," the study noted.
PFAS emissions are not regulated at a US- or EU-wide level, but the European investigation uncovered an "extensive lobbying process to water down the proposed EU-wide bans".
Last year a peer-reviewed study found that widespread concentration of synthetic chemical pollutants has already spilled deep into the danger zone.
