Removal of Nonylphenol Ethoxylates by Water Treatment Processes Reference: 98/TX/01/5 ISBN: 1 84057 131 4 Published Date: 17/04/2002 Examines the effect, under laboratory conditions, of aeration, chlorination, ozonisation, coagulation and powdered activated carbon on nonylphenol ethoxylates, a class of compounds, that may have oestrogenic properties. The report makes several preliminary conclusions on their removal, but suggests that further experiments under a wider range of conditions may be required. Price: £10   Add To Cart

The Implications of Oestrogenic Substances in the Environment Reference: 95/DW/05/3 ISBN: 1 84057 046 6 Published Date: 17/04/2002 There is increasing scientific and public concern about the potential effects of oestrogenic compounds in the environment on male reproductive health. Research in the UK has shown that male fish exposed to sewage effluents appear to undergo biochemical changes normally found only in sexually mature females. This has led to public fears regarding possible contamination of drinking water with oestrogens, as a consequence of indirect re- use of water. This report critically reviews the available evidence for a possible link between oestrogenic substances and reproductive disorders and the relevance of these findings to the Water Industry. It concludes that the data are sufficient to require that the subject be taken seriously, but insufficient to suggest that major changes in pollution legislation and control should be precipitated. Recommendations on further research are given. Price: £10   Add To Cart

Effect of Water Treatment Processes on Oestrogenic Chemicals Reference: 96/DW/05/10 ISBN: 1 84057 006 7 Published Date: 17/04/2002 Preliminary investigation into the effect, under laboratory conditions, of chlorination, coagulation, ozonation and powdered activated carbon (PAC) on a range of chemicals (steroids and nonylphenols) that have demonstrated oestrogenic activity in laboratory assays. Indicates the likely effects of the various treatments but concludes that confirmation, under a wide range of conditions, requires more extensive investigation. Price: £10   Add To Cart
