Abstract
Since the ban of tributyltin in antifouling paints, many alternative biocides have been introduced to prevent settlement and growth of marine organisms on ship hulls. Zinc pyrithione (ZnPT) is one of the most frequently used alternative biocides in antifouling paints. This paper reviewed the overall chemical properties, toxicological characteristics, and environmental fates of ZnPT, as well as the analytical challenges of studying pertinent processes. ZnPT is generally toxic to a wide range of marine organisms, including algae, bivalves, sea urchins, polychaetes, crustaceans, and fish, typically at mu g/L levels. ZnPT can be transchelated into other compounds in the presence of metal ions, and photodegrades when exposed to UV light. ZnPT is also reported to be biodegraded or hydrolyzed forming several metabolites of their own toxicity and stability. However, ZnPT accumulates in the water column or sediment, if it does not degrade at certain environmental conditions. To determine potential risks caused by ZnPT in the marine environment, studies have evaluated the environmental distribution of ZnPT with various chromatographic or voltammetry methods. Unfortunately, rapid transchelation and degradation of ZnPT in both the marine environment and laboratory interfered with most of the methods employed, making it difficult to evaluate its environmental distribution. More robust and sensitive analytical methods need to be developed to reliably describe the environmental release and distribution of ZnPT. To comprehensively understand the risk posed by the input of ZnPT into the marine environment, total degradation processes and its potential products also need to be adequately addressed.
