These may include pallor, nausea, vomiting, diarrhea, abdominal cramps, headache, dizziness, eye pain, blurred vision, constriction or dilation of the pupils, tears, salivation, sweating and confusion.
Methyl parathion has a half-life in aqueous solution of 175 days, and 10 days to two months in soils. The rate of degradation increases with temperature and with exposure to sunlight.
