“…In general, low concentrations of BTs detected in surface sediments may be a result of (i) sampling location, as some samples may be located far from the main sources, (ii) a decrease in input because of the TBT-based antifouling paint ban, and (iii) degradation in the environment caused by hydrodynamic processes and human activities, such as dredging and ship traffic (Radke et al 2008). Whereas in some environments, TBT impact was reduced after the antifouling ban (Airaksien et al 2010;Garg et al 2009), in other areas (mainly development countries), the concentrations detected after the ban were higher (Filipkowska et al 2011;Kim et al 2011;Kim et al 2015). Corresponding with these results, Paranaguá and Itajaí (located along the Brazilian southern coast) were the most impacted estuaries, as the presence of BTs was observed in biotic and abiotic matrices.…”

Butyltin compounds (BTs), including tributyltin (TBT) and its degradation products, dibutyltin and monobutyltin, have been found in a diversity of aquatic systems and causing toxic effects in target and nontarget organisms. They enter in coastal systems through different sources (as antifouling paints, industrial effluents, etc.) where they interact with biotic and abiotic components, and their distribution is commonly determined by the morphological and hydrodynamic conditions of the coastal systems. In this study, we discuss the contamination by BTs on a spatial scale (eight estuaries with three subareas each) and in different compartments of the estuaries (sediments, suspended particulate matter (SPM), and estuarine catfish tissues (liver and gills). Lower concentrations of BTs were found in the sediments (n.d. to 338 ng g(-1)) in comparison to studies before a ban of TBT in antifouling paints was enacted, mostly indicating an old input or preservation related with sediment properties and composition. For SPM samples (n.d. to 175 ng L(-1)) as well as in fish tissues (n.d. to 1426 ng g(-1)), the presence of these compounds was frequent, especially in the fish due to their movement throughout the estuaries and the potential to assess point sources of BTs. These results indicate that BTs persist in the environment, with variation in amounts between investigated estuaries and even at locations inside the same estuary, because of ideal preservation conditions, transport to remote areas, and input from different sources.

“…High TBT concentrations in relation to the sum total of DBT and MBT (butyltin degradation index; BDI < 1) in the samples indicate the recent input of TBT into the environment. 63 In the current study, the BDI ranged from 0.3 to 4.6 (Table 1), and the highest BDI was observed in sediments collected along the Swedish coast. The calculated BDI in sediments collected from stations KM, UW, and 20 located along the Polish coast was a little larger than 1, which indicated no recent inputs of TBT into the environment.…”

In order to know the occurrence of butyltins in water environment in Three Gorges Reservoir Region (TGRR), China, surface water samples from Chongqing to Yichang in TGRR were collected in March 2012. All water samples were extracted by solid phase micro-extraction (SPME) and measured by gas chromatograph (GC) with mass spectrum (MS). Results showed that both the mainstream and tributaries of Yangtze River in TGRR were polluted with butyltins, and the concentrations of butyltins did not exhibit any specific trend of variation in surface water along the Yangtze River. Most of butyltins were MBT which was found in 21 of 28 sampling stations, and concentrations varied from ND to 38.90 ng Sn/L. TBT was the next most commonly found in 9 of 28 stations with the highest level of 393.35 ng Sn/L. DBT had the lowest detection rate and was detected only in 1 of 28 stations with the level of 23.09 ng Sn/L in Tongguanyi. Butyltin degradation index (BDI) in the surface water in TGRR suggested that fresh TBT inputs or may also be attributed to very slow degradation in this region. Our study indicated that the main source of TBT contamination in TGRR may attribute to shipping activities and that particular attention should be paid to the issue of butyltins pollution in TGRR.
