Resumen

MAHOMED, SI; VOYI, KVV; ANECK-HAHN, NH  y  DE JAGER, C. Oestrogenicity and chemical target analysis of water from small-sized industries in Pretoria, South Africa. Water SA [online]. 2008, vol.34, n.3, pp.357-364. ISSN 1816-7950.

Increasing concern about endocrine disrupting chemicals (EDCs) and their effects on humans, animals and the environment resulted in this study being conducted. Water from 7 sites in the Pretoria West area (South Africa), with significant numbers of small-sized industries, was screened for oestrogenicity, using the Recombinant Yeast Cell Bioassay (RCBA). Target chemical analyses were carried out to establish the presence of EDCs, including p-nonylphenol (p-NP), bisphenol A (BPA), phthalate esters, polychlorinated biphenyls (PCBs) and various organochlorine pesticides, including dichlorodiphenyltrichloroethane (DDT). p-NP, PCBs and organochlorine pesticides were detected using LECO Pegasus II MSTOF and BPA and phthalates were detected using the GC-MS method. Oestrogenic activity was detected in all the samples collected from these sites. Lindane, an organochlorine pesticide, was detected at one site. p-NP, PCBs and phthalate esters were detected at some of the other sites. Small-size industries were found to contribute to EDC pollution of water in the Pretoria West area.

Palabras clave : oestrogenicity; endocrine disrupting chemicals (EDCs); p-nonylphenol (p-NP); polychlorinated biphenyls (PCBs); bisphenol A (BPA); phthalate esters; organochlorine pesticides; dichlorodiphenyltrichloro-ethane (DDT); lindane.
