Abstract

The aim of this research was to assess the level of pesticide residues in biota (three staple vegetables) commonly cultivated in gboko. Telfairia occidentalis (fluted pumpkin), Talinum fruticosum (waterleaf) and Vernonia amygadalina (bitter leaf), were collected from three selected farms in gboko, Benue state. The vegetables were analysed for the presence of three pesticides (Relisate, weed crusher and reliquat) using UV-visible spectrophotometer. The results of the pesticide residues analysis revealed that fluted pumpkin leaves and waterleaf contains  all the pesticides analysed at different concentration of 1.30, 0.343, 0.117 mol/l respectively and 1.30, 0.822, 0.617 mol/l respectively. The analysis indicates that, Bitter leaf contains only two pesticides: weed crusher; 0.051 mol/l and reliquat; 0.069 mol/l while Relisate was below detection. Also, all the pesticide residues were non- compliant with the FAO/WHO and CNH MRL standard for leafy vegetables; 0.07 and 0.2 mg/kg. This implies that continuous monitoring and education of farmers about proper use of pesticides is necessary. The evaluation and determination of water quality in biota within Gboko Local Government area of Benue State have provided valuable insight into the current aquatic ecosystem. The various parameters analysed show that, the PH for four samples collected are, sample A 6.76, (30.20c), sample B=6.45(30.3oC),  Sample C, 6.56(30.4oC), Sample D=5.91 (30.70C). The total dissolved solid (TDS) were Sample A, 374PPM, Sample B, 125PPM, Sample C, 107PPM, Sample D, 47PPM. The chloride concentration were, Sample A=0.0465mol/l, Sample B=0.025mol/l, Sample C=00.043mol/l, Sample D=0.0265mol/l. The total suspended solid (TSS) were, Sample A, 8.55x10-10mg/l, Sample B, 6.85x10-10mg/l, Sample C=1.4x10-10mg/l, Sample D=8.7x10-10mg/l. The total solid (TS) were:  Sample A=4.450mg/l, Sample B=35.145mg/l, Sample C=8.950mg/l, Sample D=170mg/l. The phosphate concentration was: Sample A=0.25mg/l, Sample B=11.28mg/l, Sample C=3.8mg/l, Sample D=6mg/l. The sulphate concentrations were: Sample A=33.9mg/l, Sample B=30.4mg/l, Sample C=24.86mg/l, Sample D=26.62mg/l. The overall results of this study highlight the current state of water quality in Gboko local government area of Benue State. The variation observed in the measured parameter indicates the presence of potential challenge to water quality in the standard ecosystem.
