Abstract

A locally formulated pesticide product with a trade name FIACO sold in a Nigerian market was investigated for the actual chemical composition aimed at specifying the number of chemical constituents and the actual active ingredient(s) present in the pesticide product. Gas Chromatography - Mass Spectrometry (GC-MS) technique was used for the analysis. Results indicated that the pesticide product contains nine (9) chemical constituents with percentage compositions as follows: Toluene (5.48%), Cumene (5.88%), 1,2,3-Trimethyl- Benzene (8.99%), Decane (6.09%), Undecane (6.25%), Dichlorvos (50.96%), Dodecane (8.02%), 11, 12-Dibromo- tetradecan-1-ol acetate (3.2%) and Pentadecane (5.13). Results equally pointed out that one of the identified components named Dichlorvos is a pesticide active ingredient which confirms its presence in the product. The identities of the chemical constituents in the product were revealed by mass spectra data. Therefore, it is a matter of public health significance and environmental sustainability to frequently monitor labeled and unlabeled pesticide products sold in the Nigerian markets in order to ascertain their true chemical composition.
