Another alarmist theme debunked: PCF’s and PCB’s don’t affect fertility

A major EU study concludes that environmental contaminants have little if any impact on human fertility and certainly much less than the alarmist meme has portrayed for 2 decades. Moreover “data indicates that global warming will not increase the spread of contaminants around the Arctic areas and the rest of the planet”.

The event marked the culmination the three-year-long EU study ‘Climate Change, Environmental Contaminants and Reproductive Health (CLEAR)’, which is headed by Danish scientists. 

Since 2010 the CLEAR project has aimed at assessing whether global warming causes an increase in the spread of the already widespread environmental contaminants such as PCB and PCF and whether increased exposure is a threat to human reproductive health.

The short answer to both questions is no, said Professor Jens Peter Bonde of the Department of Public Health at Copenhagen University.

“Most people probably feel they already know about the negative effects of environmental contaminants but with this study we can conclude that these contaminants really pose no major threat to human fertility,” he said.

On top of that, he added, their data indicates that global warming will not increase the spread of contaminants around the Arctic areas and the rest of the planet.

Some 1,400 pregnant women and 600 spouses from Greenland, Hungary and Poland were examined for the CLEAR project, which is the largest project so far to study the effect of more than 20 known environmental contaminants’ toxicity on human fertility.

While no major negative effects were found on the subjects’ reproductive health, the scientists did see cases of harmful properties from the contaminants of which most have been banned by the UN since 2004.

”We found some minor correlations between contaminants and lowered sperm quality plus hormone changes in men,” conceded Bonde.

He did, however, add that it these effects may not be of clinical relevance.

”We’d rather emphasize on the fact that we’ve carried out extensive analyses of contaminant levels in men and women and that the general picture looks peaceful.”
