INFANT HEALTH RISK RESULTING FROM HUMAN MILK AND CEREALS CONSUMPTION IN NORTH OF COTE DIVOIRE USING THE THEORICAL EXCESS CALCULATION

Organochlorine pesticides have been widely used in the north of C?te dIvoire in agriculture (cotton field) and in vector-borne disease eradication programs (tse-tse fly). The residues of these compounds were determined in a total of 100 samples of human breast milk and in 80 samples of cereals (maize and rice) collected in Korhogo and Sinematili, in the north region of C?te dIvoire, using gas chromatography with electron capture detector. The results showed the presence of the same type of organochlorine pesticides in human milk and in the foodstuffs. The DDT and its congeners and the cyclodiene compounds recorded the higher average concentrations in both cereals and human milk. However, p,p-TDE, p,p-DDE and p,p-DDD constituted the main metabolites of DDT in the cereals samples. As Children have lower weights than adults, they are more vulnerable by eating food contaminated by the organochlorine pesticides. Risk assessment for infant from 0 to 18 months resulting from cereals and milk consumption was carried out by using the theoretical excess calculation (f). The high values of f were obtained for infants from 0 to 6 months.
