Abstract

Pollutants such as biocides, ballast, exhausts and spilled oil and chemicals from vessels are investigated for marine environmental protection by many scientific techniques. We reported the environmental fate of booster biocide from antifouling paints and micro-analysis of particulate matter from diesel engine for environmental assessment. Photolysis of zinc pyrithione (ZnPT) was investigated by HPLC and xenon lamp. Photolysis is main degradation process of ZnPT. The HPLC study successfully identified the photo-degradation products which are Pyridine-2-sulfonic acid (PSA) and 2, 2'-Dipyridyl disulfide (DPS). Exhaust particle from diesel engine were analyzed by Scanning Microscopy and X-ray diffraction. Edge Particles include carbon and oxygen mainly and edgeless particles include CaSO4 were observed. These techniques for speciation were useful tools for environmental fate analysis and risk assessment.
