Antifouling biocide zinc pyrithione (ZnPT) and its biological fate have received little attention because this compound was assumed not to be persistent in marine ecosystems. An analytical procedure was developed that has proved to be efficient and very sensitive in extracting ZnPT and its main secondary products, Zn and ionized pyrithione (PT(-)), from both seawater and biological samples, namely in the gills and digestive gland of the bioindicator species Mytilus galloprovincialis. Short-term experiments were carried out to investigate ZnPT toxicity and bioaccumulation. The effects on survival and tissue bioaccumulation of ZnPT and its secondary products were studied on adult mussels from a natural population, collected in the harbor area of Porto Santo Stefano (Italy) and exposed to sublethal doses of the biocide for up to 7 d. Zinc pyrithione was shown to be persistent in the experimental seawater in the short term. A basal level of ZnPT and ionized PT(-) was detected in the mussels, indicating that ZnPT availability in the sampling site is already high enough to induce a detectable accumulation in individuals of the native population. Zinc pyrithione rapidly accumulated in the tissues of the exposed mussels, proportionately to both exposure concentration and time, identifying the gills and digestive gland as important targets in the biological pathway of the contaminants. Even though the 7-d median lethal concentration (LC50) = 8.27 µM established here appears high with respect to reported ZnPT environmental concentrations, the results indicate that this biocide could represent a threat for marine organisms in coastal environments and that further investigations on its biological effects at sublethal doses are needed.

“…For instance, ZnPT was extremely toxic to embryo development of the sea urchin Anthocidaris crassispina with a particularly low no observed effect concentration (NOEC) at 1 × 10 −11 g/L (Kobayashi and Okamura, 2002), while the 28-d LC50 of ZnPT on juvenile rainbow trout O. mykiss was only 4.6 g/L . ZnPT at as low as 0.16 and 0.32 g/L was found to affect the long-term survival and reproduction of the polychaete Dinophilus gyrociliatus (Marcheselli et al, 2010a).…”

“…Also, somewhat in a reverse trends, after many legislations prohibited the use of the highly toxic tributyltins antifoulant biocide [8], novel antifouling agents are appearing such as zinc pyrithione [9] or arsenic oxides, acetoarsenite and sublimated arsenic polysulfides which are now used as biocides in the production of antifouling coatings [10]. …”

A review is presented of how one defines emerging contaminants and what can be included in that group of contaminants which is preferably termed “contaminants of emerging concern”. An historical perspective is given on the evolution of the issues surrounding emerging contaminants and how environmental scientists have tackled this issue. This begins with global lead contamination from the Romans two millennia ago, moves on to arsenic-based and DDT issues and more recently to pharmaceuticals, cyanotoxins, personal care products, nanoparticles, flame retardants, etc. Contaminants of emerging concern will remain a moving target as new chemical compounds are continuously being produced and science continuously improves its understanding of current and past contaminants.
