“…Six studies have analyzed organotins in sediments from areas under the influence of important harbors from the southern (São Francisco do Sul, Itajaí-Navegantes, and Imbituba (Oliveira et al 2010); Paranaguá Bay (Santos et al 2009); southeastern (Coast of São Paulo (Godoi et al 2003b)); Guanabara Bay (Fernandez et al 2005;Almeida et al 2004); and northeastern (Todos os Santos Bay (Felizzola et al 2008)) Brazil.…”

Organotin compounds (OTs) were used in antifouling paints for more than four decades. However, due to their widespread intensive use and high toxicity, undesirable effects in non-target marine organisms have been detected since the early 1980s. Consequently, the International Maritime Organization banned new maritime applications of these products on January 1, 2003 and their presence on ship hulls from January 1, 2008. Although extensively studied in Europe, North America, Oceania, and Asia, environmental levels and effects of organotin contamination are still poorly known for South America. Thus, the current review aimed to present the actual status of this problem in South America by summarizing and comparing the available data in the literature. An overview of the OTs concentrations in sediment and biota and their effects, mainly imposex in marine gastropods, are presented. This work showed that in Atlantic coastal areas of South America there are "hot spots" of OTs contamination, similar to that observed in industrialized countries of Northern Hemisphere. On the other hand, the number of accomplished studies in the Pacific coast is extremely low. Despite the limitation on studies about OTs environmental levels and their related effects, the available data pointed out for a widespread TBT contamination along the South American coastal areas. Therefore, the establishment of baselines of organotin contamination in the Pacific coast and the implementation of temporal trend studies in the South American coastal areas is crucial to verify the effectiveness of local regulations and OTs global ban, and to map the most sensitive areas related to present and future antifouling impacts.

“…Some BTs might be associated to the circulating suspended matter and cannot reach the sediments due to local dynamics. Felizzola et al (2008) suggested that the current driven dispersion in the water phase prior to sedimentation would explain low BTs values in areas of Todos os Santos Bay far away from major sources. However, degradation and loss processes of sedimentary BTs may occur along the way from the port to the beaches.…”

The distribution of butyltins (BTs) and polycyclic aromatic hydrocarbons (PAHs) were studied in surface sediments to assess how relevant is Mar del Plata port (Argentina) as a source of contamination to the surrounding environments. Within the port, TBT concentrations ranged from 24.2 to 150 ng Sn g(-1) and PAHs (Σ16) from 180 to 17,094 ng g(-1). At the surrounding beaches, PAHs were detected at low concentrations and TBT concentrations reached 10.9 ng Sn g(-1). Although those low levels indicate that the Port might not be an important source of contamination to the surrounding beaches, the very low TOC content and the coarse grain size of the beaches sediments could explain the sedimentary levels. The results show a reduction in TBT levels in Mar del Plata port after national and international use restrictions of TBT-based antifouling paints.
