Detection of Pesticides Residues and Metals in Water and Soil Systems from Certain Industrial and Agriculture Areas at Kalubia Governorate, Egypt.

Abstract

The pesticide residues in drainage water. ground water, sediment and agriculture soil samples collected from different locations through four different seasons at Kalubia govemortae were monitored within the year 2OOO/2OOI. The obtained results showed that the detected pesticide residues were varied in their types and structures between the five sites. The positive frequencies of pesticides contamination in summer reached 44.44, 40.74, 48.15, 48.15 and 51.85 % as total monitored compounds at El-esmalia, EI Kanater, EI-sanafen, El-mazallate and EI-happy land waters. respectively. On the contrary, winter water samples were found contained the lower number of compounds. As for ground water, organochlorine insecticides were detected in very small amounts in some areas and seasons. In water sediment. few pesticides were detected. especially in autumn. On the contrary, agriculture soil samples recorded high pesticide residues than that detected in sediment. The seasonal distribution of pesticide residues was varied from site to site. In general. Pesticide residues were found in more numbers and amounts in summer, while winter samples were contained the 100vest values. In general, it was found that the detected amounts of pesticides residues were always under the permissible levels of pesticide residues. In case of the detected metals in the samples of drainage water and/or ground water, the obtained results indicate tile negligible existence of metals, i.e. Co, Ni, Cr and Pb, while Mn was the only exception" which exhibited the high amounts in water samples at the three selected sites.
