Occurrence of bisphenol A, nonylphenol, octylphenol and heavy metals in groundwater from selected communities in Ibadan, Nigeria.

Endocrine disruptors (EDs) such as bisphenol A (BPA), nonylphenol (NP), octylphenol (OP) and heavy metals in drinking water supply represent a significant threat to human health. In Nigeria, little is known about the presence of EDs in various environmental media. This study was conducted to determine the concentrations of BPA, NP and OP in groundwater samples from selected communities in Ibadan, Nigeria.
