Abstract EN
The use of organochlorine pesticides has been banned worldwide due to their toxicities.
However, some farmers use them illegally because of their potency.
The aim of this study was to assess the level of organochlorine pesticide (OCP) residues and the potential health risk associated with vegetables, soil, and groundwater obtained from farms in Ayigya, Nsenie, Gyenyase, and Kentinkrono in Kumasi, Ghana.
A total of 15 samples were analyzed using a gas chromatograph equipped with an electron capture detector.
The highest mean concentration of 184.10 ± 12.11 µg/kg was recorded for methoxychlor in cabbage from Ayigya.
Beta-hexachlorocyclohexane (beta-HCH) recorded the lowest mean concentration of 0.20 ± 0.00 µg/kg in cabbage from Ayigya.
The combined risk index showed significant health risk to children than adults.
The soil samples mainly contained methoxychlor followed by dichlorodiphenyltrichloroethane (DDT), aldrin, and other OCPs.
Concentrations of total HCHs, total DDTs, and total OCPs in the soil samples ranged from <0.01 to 49.00, <0.01 to 165.81, and <0.01 to 174.91 µg/kg, respectively.
Among all HCH and DDT isomers, only β-HCH and p,p′-DDT were detected in some of the water samples.
Carcinogenic risk values for β-HCH, aldrin, and p,p′ DDT in the groundwater were found to be >10−6, posing a potentially serious cancer risk to consumers.
Moreover, the hazard quotients (HQs) of aldrin exceeded the threshold value of one, indicating that daily exposure is a potential concern.
