Prolonged exposure to organophosphates in low concentrations caused diarrhoea in 38 students, lecturers
and other personnel at an agricultural college. The symptoms
of those affected, plasma pseudocholinesterase levels, topography of the orchards and vegetable gardens,
the various insecticides and quantities used, and the
exposure due to prevailing winds have been studied. We
conclude that safety and precautionary measures must
be strictly enforced.
