“…In comparison with those values reported in other countries, the levels of BTs obtained in this study were similar with those in São Vicente Estuary (Brazil) [13], Coast (Vietnam) [30], North coast of Kyoto (Japan) [31], but significantly lower than those in Kochi Harbor (India) [32], estuaries of Gipuzkoa (Spain) [33], Northern Adriatic Sea (Slovenia) [34], Santa Catarina Harbors (Brazil) [13] and coast of Mediterranean (Spain) [24].…”

“…Coastal zones, including harbors, are usually seriously polluted areas of OTCs because of intensive human activities and heavy marine traffic [13,14]. Fishing port is a harbor or a part of harbor for landing and distributing ocean products, where OTCs could be released not only from antifouling coatings on vessels, but also from many land sources, such as manufacture and maintenance of fishery-related facilities.…”

The concentrations and species of organotin compounds (OTCs) in 52 surface sediment samples from nine fishing ports along the Chinese coast were studied. Butyltins (BTs) and phenyltins (PhTs) were derivatized using sodium tetraethylborate (NaBEt 4 ) and determined by head-space solid-phase microextraction (HS-SPME) gas chromatography coupled with a flame photometric detector (GC-FPD). The concentrations of OTCs ranged from <3.6 to 194 ng (Sn) g −1 dry weight (dw) for monobutyltin (MBT), <2.3 to 41.5 ng (Sn) g −1 dw for dibutyltin (DBT), <0.7 to 86.0 ng (Sn) g −1 dw for tributyltin (TBT) and <5.1 to 66.1 ng (Sn) g −1 dw for monophenyltin (MPhT), respectively. The concentrations of diphenyltin (DPhT) and triphenyltin (TPhT) were below the limit of detection (LOD). BTs were the main species in the sediments except for the samples collected from Shazikou fishing port in Qingdao. The concentrations of MBT were higher than DBT and TBT. The concentrations of OTCs in the sediments varied widely among different sampling locations. The concentrations of BTs were much higher in the samples collected from fishing ports close to the South China Sea than those in coast of the East China Sea and the Yellow Sea. MPhT was prevalent in most sampling stations except for those in coast of the East China Sea. The environmental and ecotoxicological risks of TBT in most sediment samples were low.

“…Therefore, MDPP sediments can be considered as low to moderately contaminated by TBT. However, the current TBT concentrations observed in sediments of Mar del Plata are in the same range as those reported for harbors from Brazil (Oliveira et al 2010), Ecuador (Castro et al 2012b), and two other Argentinian ports (Bigatti et al 2014). Thus, the present TBT levels for MDPP are still high and represent a risk to marine life.…”

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.

“…141 Presentes até recentemente em tintas anti-incrustantes (de segunda geração) utilizadas em embarcações, os compostos organoestânicos têm sido bastante avaliados em amostras de águas e sedimentos, principalmente em ambientes aquáticos estuarinos, por estarem inequivocamente relacionados ao imposex, fenômeno que consiste no surgimento de caracteres sexuais masculinos em fêmeas de neogastrópodes. [142][143][144][145][146][147][148][149][150][151][152] Nos anos mais recentes tem havido um crescimento dos estudos envolvendo os contaminantes químicos emergentes, ou simplesmente contaminantes emergentes, em ambientes aquáticos, dados que estas substâncias, frequentemente presentes em águas naturais e de abastecimento público, assim como de sedimentos, entre outros, não são determinadas nos programas oficiais de monitoramento da qualidade da água. Muitas destas substâncias são suspeitas de provocar interferência no sistema endócrino de organismos intactos, incluindo os seres humanos.…”

ENVIRONMENTAL CHEMISTRY IN BRAZIL IN 40 YEARS IN THE SBQ. This paper aims to present an overview of the ongoing of the Brazilian environmental chemistry over the last forty years inserted in the context of the Brazilian Chemical Society (SBQ). Initially, a brief history presents the main milestones and premise of its "birth" in the 1980s, as well as the set of major actions taken within the SBQ to consolidate and strengthen this area of research. Then, in a separated approach between atmosphere, hydrosphere and lithosphere, we present the evolution of the main topics covered in Environmental Chemistry in Brazil, as well as the contribution of the chemists in the interdisciplinary scenario that constitutes this area. Finally, an overview of the evolution of the teaching of Environmental Chemistry in Brazil is presented.Keywords: environmental chemistry, atmosphere, hydrosphere, lithosphere, HISTÓRICO DA QUÍMICA AMBIENTAL NO BRASILNo Brasil, a Química Ambiental se desenvolveu a partir de um vínculo estreito com a Química Analítica, que se consolidou com base em uma escola consolidada e tradicional, com uma visão clássica sobre seu papel e voltada, em primeira instância, para o desenvolvimento de protocolos analíticos e elucidação de problemas estabelecidos dentro do laboratório. Portanto, boa parte dos primeiros químicos ambientais tinha uma forte ligação com a Química Analítica e eram poucos aqueles com experiência em trabalhos de campo e amostragem ambiental. Nos anos 1980, a pesquisa em Química Ambiental conduzida em nosso país tinha como base o monitoramento de espécies químicas presentes na hidrosfera, atmosfera e biota.1 Existem documentos evidenciando a escassez de atividades de pesquisa dedicadas ao estudo da reatividade química e comportamento de poluentes não apenas nos três compartimentos mencionados anteriormente, mas igualmente em suas interfaces.2 Estas circunstâncias resultaram em um desenvolvimento mais lento da Química Ambiental brasileira, quando comparada com a de outros países, especialmente os desenvolvidos. Não obstante estes aspectos, nos dias atuais a Química Ambiental ocupa posição de destaque no cenário científico nacional, tendo igualmente alcançado projeção internacional. Vários eventos científicos também têm contribuído para isso, tais como as Reuniões Anuais da Sociedade Brasileira CENÁRIO DE ESTUDO DA QUÍMICA AMBIENTAL NO BRASILPara contemplar o cenário das pesquisas em Química Ambiental no Brasil, decidimos dividir os estudos em hidrosfera, atmosfera e litosfera, embora estes compartimentos sejam integrados e não haja um mais importante que o outro e tampouco podem ser vistos separadamente. Além disso, este texto não tem a pretensão de fazer uma revisão exaustiva das publicações nestas áreas dentro da Química Ambiental, mas sim de apresentar um panorama da evolução e dos temas que foram e estão sendo estudados nestes 40 anos da Sociedade Brasileira de Química, apresentando exemplos de alguns destes trabalhos.
