“…The resulting correlation coefficients between soil physico-chemical properties and the mean total organochlorine pesticides residues, revealed high significant (p<0.05) correlation only between the organic matter content and the OCP measured in the soil throughout the entire study area. This suggests that pesticides residues levels in the soil are possibly more associated with organic matter content of the soil, and which could be attributed to the fact that organochlorine pesticide molecules have high tendency of binding to organic carbons in soil, similar to fats or lipids of plants and animals as reported by Swackhamer et al (1988) and Bentzen et al (2008). The observed correlations coefficients between other measured physico-chemical parameters of the soil and the OCP showed no significant correlation, indicating little influence of these soil characteristics on the OCP level.…”

Ondo State being the highest producer of Cocoa in Nigeria constitutes the most probable area with the highest use of chemical pesticides to enhance cocoa production. As effective as these chemicals may be in achieving this goal, the incidence of their residues on non-targeted substances and the total environment, with the attendant adverse effects have being of serious concerns. Our objective in this paper is to assess contamination of farm soils by organochlorine pesticides applied on cocoa farms within the Central Senatorial District of Ondo State, Nigeria. Soil samples were collected from selected cocoa farms and analysed for organochlorine pesticides residues using GC-MS. Some soil physicochemical properties including pH, particle size and organic matter that may influence the dynamics of the pollutants were also determined. Organochlorine compounds detected at varied concentrations include Endosulfan I and Endosulfan II occurring most frequently with highest concentrations of 350.10 mg/kg and 3.55 mg/kg respectively. Other organochlorine compounds detected were Heptachlor, Heptachlor epoxide, Aldrin, Deldrin,, isomers of Benzene hexachloride: α-BHC, β-BHC, δ-BHC, and Ƴ-BHC (lindane). The concentrations of the organochlorine pesticides (mg/kg) measured in the soil samples showed significant (p<0.05) correlation with the total organic matter contents of the soil. Findings from this research thus, provide information on the current and health risk residue levels of organochlorine pesticides in soil from this region with which future environmental performance on the use of pesticides on cocoa farms could be progressively monitored.

“…It has been estimated that the degradation of DDT in soil ranges from 4 to 30 years, while other chlorinated OCPs may remain stable for many years after their use (Afful et al, 2010). Because of their inability to break down in the environment, their degradation is restricted by chemical, physical, biological and microbiological means (Afful et al, 2010;Darko and Acquaah, 2007;NCEH, 2005;Swackhamer and Hites, 1988). They are liposoluble compounds and are capable of bioaccumulating in the fatty parts of biota such as breast milk, blood and fatty tissues (William et al, 2008) in the food chain.…”

“…Furthermore, the model is only an approximation and useful mainly for neutral organic compounds (5,(7)(8)(9). SM 2 is an ionizable compound and would not be expected to have a predictable BCF, because the ambient pH value would be a contributing factor.…”

A steady-state bioconcentration and elimination of sulfamethazine (SM2) in the sturgeon (A. schrenkii) was conducted in flow-through aqueous conditions. Two treated groups of fish were exposed to concentrations of 1.00 and 0.10 mg/L of SM2, respectively. SM2 and its main metabolite, N4-acetyl-SM2, were determined in both fish muscle and water during the 8-day uptake period and the subsequent 6-day elimination period. Rapid uptakes of the drug were observed in both treated groups. Muscle tissue residues plateaued after ∼3 days. The bioconcentration factor in muscle (BCFm) in the low-concentration drug solution was 1.19 and that in the high-concentration-treated level was 0.61. The calculated biodegradation index was 3.72%. The elimination half-times (t1/2) of the two treatment levels were 19.44 and 23.52 h, respectively. The result indicates that SM2 will neither bioconcentrate in individual aquatic organisms nor biomagnify in the food chain, although the BCFm was relatively higher under the low-concentration exposure.
