“…Quase toda radiação ultravioleta emitida pelo sol, com comprimento de onda menor que 290nm, é absorvida pela camada de ozônio. Entretanto, a luz de 290nm possui uma energia de aproximadamente 300kJ mol -1 , o suficiente para romper as ligações estanho-carbono, que requerem uma energia de dissociação entre 190-200kJ mol -1 (Omae, 2006;Hoch, 2001).…”

“…A degradação biótica por microorganismos é a principal forma de decomposição destes compostos (Alzieu, 2000;Omae, 2006). A meia-vida do TBT neste processo, em águas doces e salgadas, é de seis dias até muitas semanas, mas a biodegradação pode ser muito mais lenta em sedimentos, principalmente em condições anaeróbias, cuja persistência está estimada entre dois anos até várias décadas (Antizar-Ladislau, 2008;Rüdel, 2003).…”

ResumoOs cascos das embarcações estão constantemente sujeitos à bioincrustação, o que resulta na diminuição significativa da eficiência operacional, elevando os custos devido ao aumento no consumo de combustível. Dentre os diversos sistemas antiincrustantes desenvolvidos para contornar este problema, os que apresentam compostos organoestânicos em suas formulações tornaram-se o foco das discussões entre órgãos ambientais nas últimas décadas. Estes compostos são considerados uma ameaça à biota aquática em áreas com intensa atividade naval e podem agir como disruptores endócrinos em invertebrados. Após as restrições impostas para o uso de tintas à base de organoestanhos, outros biocidas vêm sendo utilizados. No entanto, tais produtos também apresentam efeitos tóxicos ao meio ambiente. Este artigo apresenta uma revisão da literatura relacionada aos riscos da exposição de organismos aquáticos aos compostos que constituem as tintas anti-incrustantes, assim como as alternativas propostas para substituir os produtos atualmente comercializados.Palavras-chave: Bioincrustação, biota aquática, ecotoxicologia, embarcações, organoestanhos, tintas anti-incrustantes. Risks to aquatic biota by the use of antifouling paints AbstractThe ship hulls are constantly subject to marine biofouling, wich results in a significantly diminution in operational efficiency, rising the costs due to the increase of fuel consumption. From the antifouling systems developed to prevent this problem, those whom present organotin compounds in their formulations became the center of discussions among environmental organs in the last decades. These compounds are considered a threat to marine life in areas with intense naval activity and can act as endocrine disruptors in invertebrates. After restrictions imposed on the use of organotin antifouling paints, others biocides have been used. However, these products also have adverse effects on marine ecosystems. This article reviews the literature related to the risks of the exposure of aquatic organisms to antifouling paints compounds, as well as the alternatives proposed to replace the products yet commercialized.

“…This fouling not only detracts from the beauty of the view in a ship but also increases the surface roughness at macro-scale and augments the resistance of the marine vehicle in the sea. The conventional anti-fouling paint used to contain a toxic organ Tin compound and is now strictly prohibited by International Maritime Organization (IMO), because it causes genetic mutations in aquatic organisms when it is released into seawater (Omae, 2006). On the other hand, antifouling paint (metal-type Tin-free SPC) with antifoulant Cu 2 O is now widely used because it has little effect on marine pollution, compared to the conventional paint containing Tin.…”

“…Organotins have been widely used for decades in industrial activities such as oil refining and the manufacture of antifouling chemicals [13,14]. Tributyltin (TBT), a compound of butyltin (BuT), was developed in the 1950s as the most effective commercially available antifouling system for decades [15]. TBT is known to have serious ecotoxicological impacts like imposex (females developing male sex organs such as a penis and vas deferens) in the gastropod Nucella lapillus or severe calcification defects in the oyster Crassostrea gigas, resulting in a population decline [16][17][18].…”

Marinas are semi-enclosed environments characterised by reduced hydrodynamic energy, high sedimentation rates, and reduced oxygen levels. The ongoing development of activities and infrastructure construction are leading to deterioration in the quality of coastal aquatic environments, creating environmental risks. Trace metal elements (TMEs) and organotins are significant contaminants, prompting this study to evaluate the added value of spatiotemporal monitoring compared to one-time sediment assessments. Two Mediterranean harbours, Port Camargue (PC) and Port Carnon (C), differing in morphology and size, were monitored for a year with regular water sampling, focusing on TMEs and organotins. Sediment contamination, notably in the technical zone, revealed concentrations of Cu (309 and 1210 mg kg−1 for C and PC, respectively), Zn (242 and 425 mg kg−1 for C and PC, respectively), and tributyltin (TBT) (198 and 4678 µg (Sn) kg−1 for C and PC, respectively) surpassing the effect range medium (ERM), while other marina stations generally stayed below this threshold. Spatiotemporal water monitoring highlighted concentrations above environmental quality standards (EQS) at all stations of the larger marina. This exceedance was systematic for Cu and Zn in all samples, ranging respectively between 2.54 and 37.56 µg (Sn) L−1 and 0.63 and 33.48 µg (Sn) L−1. A notable temporal dynamic for TBT and Cu was also observed. Conversely, the open marina, connected to the open sea, rarely exhibited concentrations above EQS in water, despite sediment concentrations occasionally exceeding ERM values. This underscores that risk assessment in these ecosystems cannot rely solely on sediment characterisation.
