| Abstract | ||
| This experiment was conducted to study the effect of irrigation with treated sewage water (TSW) on the levels of pesticide residues in plants cultivated in loamy sandy or silty loam soil. The results indicated that an increase of organochlorine (OC) level when the two soil types were irrigated with agriculture drainage water (ADW) and ground water (GW) compared with sewage water (SW), at the 111 and rd growing seasons. Lower pesticide residues were found when the soils were irrigated with TSW. Also, water source affects greatly the level of pesticide residues observed by plants. According to the total detected pesticide residues, GW caused high contamination in wheat grains or radish leaves, followed by SW, while TSW caused the lowest. However, all detected pesticide residues in wheat grains or radish leaves did not exceed the MRLs contamination of Codex, 2000. | ||
