Levels of metabolites (breakdown products) of malathion and chlorpyrifos in the urine of children taking part in a study of effects of an organic diet:

Malathion metabolite Chlorpyrifos metabolite
Study phase No. of samples Mean (µg/L) Maximum (µg/L) Mean (µg/L) Maximum (µg/L)
Nonorganic 87 2.9 96.5 7.2 31.1
Organic 116 0.3 7.4 1.7 17.1
Nonorganic 156 4.4 263.1 5.8 25.3
