Findings of the study, "Chlorpyrifos Exposure and Urban Residential Environment Characteristics as Determinants of Early Childhood Neurodevelopment," are online in the American Journal of Public Health.
The study examined the association between exposure to the pesticide and mental and physical impairments in children in low-income areas of New York City neighborhoods in the South Bronx and Northern Manhattan. Chlorpyrifos was commonly used in these neighborhoods until it was banned for household use by the U.S. Environmental Protection Agency (EPA) in 2001. It is still used as an agricultural pesticide on fruits and vegetables. The EPA registration of chlorpyrifos for agricultural use is currently under review, with a public comment period scheduled for the coming months.
"This study helps to fill in the gaps about what is known about the effect of the pesticide chlorpyrifos on the development of young children by showing that there is a clear-cut association between this chemical and delayed mental and motor skill development in children even when there are other potentially harmful environmental factors present," said Gina Lovasi, PhD, lead author and Mailman School of Public Health assistant professor of epidemiology. Dr. Lovasi conducted the research as a Robert Wood Johnson Foundation Health & Society Scholar at the Mailman School.
Chlorpyrifos is not restricted at all in Australia and in fact it is sprayed under most homes and arround the outside of the slab. Studies have shown it is in indoor air if sprayed under the slab. I have mislaid the link to that but my personal experience is that if I go into a house that has been sprayed I get symptoms of OP poisoning
If you garden next to the house it will be what you grow. in suburbia it will be in the ground water .Plus of course farmers love it and spray it on wheat and fruit and veggies.
