Summary Introduction
To analyze:
Whether switching from phase 1 to phase 2, that is, nonorganic to organic, lowers the amount of pesticides secreted in the urine of the children or not in the following experiment.
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 |
Introduction:
Organic foods are produced using methods that meet the standards of the organic farming. The organic food tends to limit the accumulation of the toxic compounds, which one might be consuming along with the nonorganic food substances.
