Book Description
This standard specifies a method of the determination of primary biodegradabilty of surfactants by aerobic micro-organisma. This standard is applicabl to determination of biodegradability of anionic surfactants characterised by sulphate and sulphonate group;polyoxyethylene nonionic surfactants characterised by single EO chain with EO number ranging from 3 to 40,or multi EO chains(double,triple,quadruple EO chains)with total EO number ranging from 6 to 60;alkyl polyglycoside surfactants;cationic and amphoteric surfactants and surfactants capable of producing rich foam during test.This standard is also applicable to determination of the biodegradability of above surfactants in detergents.

Book Description
Using renewable fuels and materials, drinking clean water and food, and breathing safe air are major issues for a sustainable world. This book reviews biodiesel production from microalgae, a promising energy source that does not compete with food production. Several advanced techniques to clean polluted waters, such as electrochemistry, ferrites photocatalysis and low-cost filtration are presented. Chapters also show various living organisms used as bioindicators of toxic metals. Decreasing ecotoxicity of pesticides using suitable surfactants is reviewed. The last chapter evidences new pollutants in urban soils, halogenated polycyclic aromatic hydrocarbons.
