Phytotoxicity of Tunisian Municipal and Textile Sludges Compared to the Produced Composts

Mohamed Anis El Hammadi, Melika Trabelsi and Belgacem Hanchi

Abstract:
In this study objective was to determine the phytotoxicity of textile sludge, municipal sludge and their produced composts made from a mixture of sludge and greenwaste (1:1 ratio w/w). The toxicity of the different materials was investigated using sunflower germination bioassays. After the incubation period, percentage of viable seeds and root length as well as germination index were determined. The germination index varied from 30.73 to 95.05% and both textile and municipal sludges presented higher phytotoxicity level than their produced composts. An important observation was that the inhibition of root growth appeared as more sensitive phytotoxicity indicator than the percentage of viable seeds. The germination index indicated the reduction of sludge phytotoxicity with composting. This research provides a basis for the further improvement of composting and for future risk assessments of compost application.
