Eine neue Studie zur Pestizidexposition in Peru stellt einen mechanistischen Zusammenhang zwischen Exposition und Krebs fest und zeigt, wie „komplexe Pestizidmischungen“ zur Entstehung von Krebs bei Menschen beitragen können, selbst bei derzeit als sicher geltenden Expositionsniveaus.

From the article:

>The authors of the study, published in *Nature Health*, said the findings call into question classical toxicological approaches that are based on the evaluation of isolated substances and the setting of safety thresholds, and demonstrate the importance of looking at the impacts of multiple pesticide mixtures.

>The US Environmental Protection Agency (EPA) and other regulatory agencies around the world typically evaluate pesticides individually and not in combination, a practice that has drawn criticism.

>“We have long assumed that pesticide risks are assessed one at a time, but in reality people are constantly exposed to complex mixtures in their everyday environment — and our findings suggest this overlooked reality may be an important component of cancer risk,” said study co-author Stephane Bertani, who is research director in molecular biology at the French Institute for International Scientific Research (IRD).

>In addition to the IRD, the research team included scientists from the Pasteur Institute and the National Institute of Neoplastic Diseases (INEN).

>The team said their study is the first to highlight the biological mechanisms by which pesticide exposure can contribute to the development of certain cancers.
