Tannage Résumé : Kenyan tannery and associated environmental samples were selected for ecotoxicological assessment. A tool-kit of techniques was developed, including whole cell biosensor and chemical assays. A luminescence based bacterialbiosensor (Escherichia coli HB101 pUCD607) (via a multi-copy plasmid) was used for toxicity assessment. Samples were manipulated prior to biosensor interrogation to identify the nature of the toxic contaminants. Untreated samples (before any manipulations) showed a strong toxic effect at the discharge point in comparison to other sampling points. Sparging was used to identify toxicity associated with volatile organics. The toxicity of contaminants, removed by treatment with activated charcoal, was identified for all the sampling points except for those upstream of effluent discharges. Filtration identified toxicity associated with suspended solids. Changes in availability of toxic contaminants due to pH adjustment of most samples from the tannery effluent treatment pits were also associated with the extreme pH values (4.0 and 8.0). The approach used has highlighted the complexity of toxic pollutants in effluent from the tanning industry. Dissection of toxicity points suggests possible remediation strategies for effluents from the tanning industry.

Tannage Résumé : With a wide experience spanning over thirty years in the Leather subsector Dr. M Mwinyihija embarked on his doctoral studies at the University of Aberdeen, focusing on the latest ecotoxicological and novel techniques that could provide environmental diagnostic insights to the tanning industry. Certain criterion was fundamental in writing this book; that the tanning industry is a major source of pollution worldwide, particularly in developing countries. Indeed the developed ecotoxicological and analytical techniques were deliberately designed on the basis of being rapid, simple and inexpensive and directed towards resolving the tanning industry challenges on terrestrial and aquatic systems. Thus the resultant research data reported, incorporates both field related and laboratory based techniques to address underlying environmental problems in the tanning sector.
