Household Pesticides may Be a Hidden Danger to Child IQ
Professor Brian Gulson at Macquarie University, however on one hand agrees that lead is harmful for children's intellectual development, but at the same time he supports many studies showing that low level exposure to organophosphate pesticides may be equally detrimental to childrens IQ.
He also stated that the confusion in the effects of lead and pesticides must have resulted because of the similarity in effects and the overlap in timing of the major use of these pesticides in the community and lead exposure studies. But other scientists have dismissed his comments as an "interesting idea" that is "not well supported" by the science.
Gulsons comments come in line with the review of guidelines for acceptable levels of lead in the blood by the regulatory bodies in the US, Canada and Australia. He said that the US is under pressure to halve the current blood lead level of 10 micrograms per decilitre.
He disagrees to the shift to 5 micrograms per decilitre saying that they do not have the technology to measure impact on IQ, or intellectual quotient, at that level. Besides, he even suggested that lead couldnt be solely blamed for all the neurodevelopmental effects.
"Many of the lead studies have been undertaken in communities where the subjects may be exposed to rodents and insects [and] the chemicals used to eradicate them," Live Science quoted him, as saying.
