Two different studies by Berkelay and Columbia university confirm that children of women who assumed food with pesticides during their pregnancy, after 7 year from birth, perform worse in IQ tests than peer whose mothers ate free-pesticide food in the same period. The researchers controlled for eduction and environmental elements which could bias the results, too. Unfortunately, the paper is not downloadable freely (it would be interesting to analyse for some selection bias issues). As a development economist, I am concerned with poverty issues. That is, it is likely that poorer families are more exposed to pesticides than wealthier ones, pushing poorer children into a pesticide poverty trap which does not allow (at best, obstacles) them to social climbing. Especially, I am thinking to developing countries or BRICS, where need for growth could lead government to subside cropping technologies which spur agricultural productivity at the expense of health conditions.
Pesticides, IQ, social climbing – A pesticide poverty trap
