Occurrence of booster biocides around peninsular Malaysia : implication of its toxicity on selected coral reef organisms

Abstract

Booster biocides were introduced as alternative antifouling products to replace tributyltin (TBT) since 1987. Irgarol (2-methylthio-4-tert-butylamino-6-cyclopro-pylamino-s-triazine) and Diuron (N-(3,4-dichlorophenyl)-N,N-dimethylurea) are the most commonly used biocides in recent decades. This thesis therefore provides the baseline information of Irgarol and Diuron from various coastal compartments such as ports and coral reef Islands waters of Malaysia Peninsular as well as the eco-toxicology effect data of the biocides to the coral reefs using fatty acid composition as biomarker.
