ORGANOPHOSPHORUS PESTICIDES FOUND IN SOME TEAS
Many of us drink tea because it is a "health drink." But
nothing is perfect. Researchers reporting in Environmental Monitoring and
Assessment discovered organophosphorus (OP) and other pesticides in certain
teas. Researchers assessed the levels of OP and other pesticide residues
in the teas and ecosystems of two tea-growing regions in Northeast India.
One ecosystem was at a lower elevation and the other at a higher elevation.
Researchers assessed pesticide levels in fresh tea leaves,
brewed teas and the ecosystems where each were grown. Teas originating at
lower elevations had higher levels of OP residues than those originating at
higher elevations. It is possible that lower elevation ecosystems (soil and
water) retain pesticides for longer periods of time than ecosystems at higher
elevations.
It is not known if teas grown in other parts of India contain
pesticide residues. Nor is it known if these residues pose a health risk to tea
drinkers. drpaulsupdates.org
