Pesticide residues in fruits at the market level in accra metropolis, ghana, a preliminary study.

A number of pesticide residues in fruits were monitored at five markets in the Accra Metropolis for almost a year. Locally produced fruits (pawpaw and tomato) and imported apple were purchased from these selected markets in the metropolis and analyzed for pesticide residues by gas chromatography equipped with electron capture detector. In all, 320 sampled fruits were extracted and analyzed for pesticide residues, mainly organochlorines (gamma-HCH, delta-HCH, aldrin, heptachlor, gamma-chlordane, heptachlor epoxide, alpha-endosulfan, p,p’-DDE, endrin, beta-endosulfan, o,p’-DDT, endrin aldehyde, p,p’- DDT, endrin ketone, and methoxychlor). The data revealed that 32.8% of the fruit samples analyzed contained residues of the monitored insecticides above the accepted maximum residue limit (MRL) whereas 48.7% were below the MRL. Nonetheless, the continuous consumption of such fruits with modest pesticide levels can accumulate and could result in deadly chronic effects.
