Abstract
The present study investigated volatile organic compounds pollution based on the principles of dilution, diffusion and
dispersion in a rural fishing community of Take, Lagos state Southwestern, Nigeria. The air samples were collected by
passive sampler (ORSA 5). The air samplers were exposed to a height of 1.5-2.0 m and sampling was carried out four
times a month for a period of 12 months. The adsorbed VOCs were desorbed with carbondisulphide (CS2) and the
solution analysed using Gas Chromatography (GC) fitted with Flame Ionization Detector (FID). The results from
analysis of the air samples collected showed that twenty (26) VOCs were captured in Take area. The VOCs were
classified thus: aromatics 43%, halogenated 28%, esters 4%, ketones 13%, alcohols 6%, ethers 6%. There is a significant
difference (Pvalue < 0.05) between the levels of VOCs in Take area. The meteorological parameters showed significant
correlations with the ambient concentrations of VOCs. The principal component analysis revealed that the major sources
of VOCs in Take areas are mainly Anthropogenic and three (3) factors were identified as sources of VOCs in the studied
area with emissions from the waste dump dominating.
