Atrazine residue in waters of Ijebu-North local government, Nigeria: implications on human health, hematological, and biochemical parameters.

Knowledge and implications of atrazine in waters from rural areas in Nigeria remain diminutive. Meanwhile, recent findings have shown presence of atrazine residue in water bodies. Atrazine level in six communities (Mamu, Oru, Ilaporu, Awa, Ijebu Igbo, and Ago-Iwoye) of Ijebu North local government, Ogun State, Nigeria using 69 hand-dug wells (HDWs), 40 boreholes (BHs) and four streams are monitored.

Implications of atrazine concentrations in drinking water from Ijebu-North, Southwest Nigeria on the hypothalamic-pituitary-adrenal axis.

There is an increasing overdependence and use of atrazine herbicide for the control of pre-and post-emergence broad leaf weeds on maize farms in rural agricultural communities in Nigeria. We carried out a survey of atrazine residue in 69 hand-dug wells (HDW), 40 boreholes (BH) and 4 streams from all the 6 communities (Awa, Mamu, Ijebu-Igbo, Ago-Iwoye, Oru and Ilaporu) in Ijebu North Local Government Area, Southwest Nigeria. The effect of the highest concentration of atrazine detected in the water from each of the communities on the hypothalamic-pituitary-adrenal (HPA) axis of albino rats was investigated.

Outcome of the first survey of atrazine in drinking water from Ijebu-North, South-West, Nigeria: Human health risk and neurotoxicological implications.

No recognised study has been conducted to monitor atrazine residue in drinking water from rural agricultural areas in Nigeria and its potential health implications. In this ecotoxicological study, we monitored atrazine residue in 69 hand-dug wells (HDW), 40 boreholes (BH) and 4 major streams from all the 6 communities (Ago-Iwoye, Ijebu-Igbo, Oru, Awa, Ilaporu and Mamu) in Ijebu North Local Government Area, Southwest Nigeria. Values of atrazine obtained were further used to evaluate the non-carcinogenic risk associated with ingestion and dermal contact in adults and children as well as neurotoxicity assessment.
