Comparative and Quantitative Appraisal of Pesticide Residues in River Water and Soil Samples from Jere Bowl Nigeria

This study assessed the concentration levels of five different pesticide residues in water and soil samples that were collected from river Ngadda in Jere bowl, Nigeria. Pooled samples from different locations within five villages were determined by using GC / MS SHMADSU (GC - 17A) with an electron capture detector (ECD) and standard operating procedures were followed. The pesticides (Hexachloro hexahydro dimethanonaphthalene, Dichlorodiphenyl trichloroethene, Cypermethrin, Chlorpyrifos and Dichlorvos) were analysed. Results obtained (µg / g for soil and µg / l for water) revealed a variation in mean concentration levels of the pesticide residues analysed. Bololo, ranged from 9.13 to 38.14 for soil and 1.01 to 15.01 for water. Dusuman; Soil (5.17 to 32.16) and water (5.17 to 32.16). Gongulon; soil (5.27 to 42.10) and water (1.03 to 5.07). Kachallari; soil (17.15 to 24.16) and water (1.11 to 3.7). Masu village; soil (13.13 to 32.19) and water (1.11 to 3.71). The concentration levels were observed to be at alarming levels higher than the maximum residue limits (MRLs) for surface water and soil as described by WHO. The occurrence of the pesticide residues in the river water and soil, are major threats to farmers that are depending on river water for their daily activities and irrigation farming, and the public that is consuming the farm produce. Hence, there are needs for monitoring of pesticides applications and their usage in the said study area and its environs.
