current methods of assessing short-term intake of pesticide residues by humans need to be modified. So concludes a study conducted by an international team of researchers. Their assertion is significant, as single exposure to some pesticide residues can be unsafe. A single high dose of organophosphates, for instance, can lead to chronic headaches. Ironically, to date attention has been mostly focussed on the long-term intake of pesticide residues.
The researchers, led by Denis Hamilton of Australia's Queensland department of primary industries, analysed worldwide data on pesticide residues in fruits and vegetables. The data had been collected via field studies and market-place surveys. Based on the information, the researchers assessed both short-term and long-term risk from pesticide residue exposure. They found that short-term exposure had been underestimated in many cases. Reason
