Washington, Mar 31 : A new study in the U. S. has found a link between an increased number of birth defects in children of women who got pregnant in spring or summer and elevated levels of pesticides in surface water across the country.
Studying all 30.1 million births, which occurred in the U. S. between 1996 and 2002, the researchers found that women whose last menstrual period occurred in April, May, June or July were at increased risk for delivering infants with birth defects.
They also found that this period of increased risk correlated with elevated levels of nitrates, atrazine and other pesticides in surface water across the country.
