Both the elements are present in antifouling marine paints and are released inadvertently into ambient sweater. Especially, Sn has often been used in the form of tributylin (TBT). Based on a step-wise pretreatment examination, Sn and Cu both inside and outside the aragonite lattice of the coral skeleton show a potential for providing marine pollution indicators. High values of extra-skeletal Cu/Ca and Sn/Ca atomic ratios were found between late 1960s and late 1980s during a period of active use of TBT-based antifouling paints worldwide. However, a significant decrease in both the ratios in the beginning of 1990s can be attributed to regulation of the uses of TBT on cargo ships by countries such as the USA, Japan and Australia.
