“…Further research has shown that plastic debris sorb, concentrate and transport POPs in the marine environment that can subsequently be ingested by marine organisms (Teuten et al, 2009;Zarfl and Matthies, 2010;Browne et al, 2013;Schirinzi et al, 2016). However, little is known about pollutant's desorption rate during digestive processes hence chemicals' potential ability to accumulate in tissue and organs and disrupt key ecophysiological processes in organism of ecological relevance (Bakir et al, 2014).…”

Plastic micro litter represents an emerging contaminant as well as a multiple stress agent in aquatic environments. Microplastics are found even in the remote areas of the world. Together with their occurrence in all environmental compartments, there is a growing concern about their potential to adsorb pollutants co-occurring in the environment. At present, little is known about this source of exposure for aquatic organisms in the benthic environment. Exposure conditions were set up to mimick the contribution of microplastics through different exposure routes. Potential biological effects resulting from these exposures were investigated in the model organism Hediste diversicolor, an annelid worm. Cellular effects including alterations of immunological responses, lysosomal compartment changes, mitochondrial activity, oxyradical production and onset of genotoxicity were assessed in coelomocytes while temporary and permanent effects of oxidative stress were also performed at tissue level. In this study polyvinylchloride (PVC) microparticles were shown to adsorb benzo(a)pyrene with a time and dose-dependent relationship. The elevated bioavailability of the model pollutant after ingestion induced a clear pattern of biological responses. Toxicity mainly targeted impairment of cellular functioning and genotoxicity in H. diversicolor coelomocytes, while permanent effects of oxidative stress were observed at tissue level. Coelomocytes responded fast and with a higher degree of sensitivity to the adverse stimuli. The results showed that microplastic particles in sediments may play a significant role as vectors for organic pollutants. The highest adverse responses were observed in those H. diversicolor exposed to sediments spiked with PVC particles pre-incubated with B[a]P when compared against sediments spiked with B[a]P and plastic microparticles separately.

“…If microplastic densities continue to increase, then substrate-associated biota such as H. sericeus may be expected to increase as well, potentially at the expense of prey such as zooplankton or fish eggs [3,4]. Future work should incorporate the dynamics of substrate-associated assemblages with ongoing work in toxicology [17], microbial ecology [21] and faunal interactions [13][14][15][16] to provide a better understanding of the impact of microplastic pollution on pelagic marine ecosystems. …”

Increased oceanic microplastic debris enhances oviposition in an endemic pelagic insect

Plastic pollution in the form of small particles (diameter less than 5 mm)—termed ‘microplastic’—has been observed in many parts of the world ocean. They are known to interact with biota on the individual level, e.g. through ingestion, but their population-level impacts are largely unknown. One potential mechanism for microplastic-induced alteration of pelagic ecosystems is through the introduction of hard-substrate habitat to ecosystems where it is naturally rare. Here, we show that microplastic concentrations in the North Pacific Subtropical Gyre (NPSG) have increased by two orders of magnitude in the past four decades, and that this increase has released the pelagic insect Halobates sericeus from substrate limitation for oviposition. High concentrations of microplastic in the NPSG resulted in a positive correlation between H. sericeus and microplastic, and an overall increase in H. sericeus egg densities. Predation on H. sericeus eggs and recent hatchlings may facilitate the transfer of energy between pelagic- and substrate-associated assemblages. The dynamics of hard-substrate-associated organisms may be important to understanding the ecological impacts of oceanic microplastic pollution.

“…68 Em todos esses ambientes estão presentes itens grandes (inteiros ou fragmentados), facilmente identificáveis, mas a atenção tem atualmente se voltado para as frações menores, possivelmente mais danosas à fauna e flora marinhas, que são os microplásticos. 78,79 Os microplásticos (< 5 mm) em ambientes marinhos têm recebido bastante atenção da comunidade cientifica na última década, 50,78 tendo inclusive merecido mais de uma dúzia de revisões da literatura (considerando-se apenas os artigos revisados por pares) nesse período de tempo. 80 Essa fração de tamanho dos plásticos tem fundamentalmente duas naturezas, a primária que são os plásticos virgens (pellets) e a secundária que são os fragmentos resultantes da degradação física, química e biológica de itens maiores.…”

Recebido em 17/7/13; aceito em 2/9/13; publicado na web em 18/9/13 OCEANOGRAPHY AND CHEMISTRY: BRIDGING KNOWLEDGE IN FAVOR OF THE OCEANS AND SOCIETY. The marine environment is certainly one of the most complex systems to study, not only because of the challenges posed by the nature of the waters, but especially due to the interactions of physical, chemical and biological processes that control the cycles of the elements. Together with analytical chemists, oceanographers have been making a great effort in the advancement of knowledge of the distribution patterns of trace elements and processes that determine their biogeochemical cycles and influences on the climate of the planet. The international academic community is now in prime position to perform the first study on a global scale for observation of trace elements and their isotopes in the marine environment (GEOTRACES) and to evaluate the effects of major global changes associated with the influences of megacities distributed around the globe. This action can only be performed due to the development of highly sensitive detection methods and the use of clean sampling and handling techniques, together with a joint international program working toward the clear objective of expanding the frontiers of the biogeochemistry of the oceans and related topics, including climate change issues and ocean acidification associated with alterations in the carbon cycle. It is expected that the oceanographic data produced this coming decade will allow a better understanding of biogeochemical cycles, and especially the assessment of changes in trace elements and contaminants in the oceans due to anthropogenic influences, as well as its effects on ecosystems and climate. Computational models are to be constructed to simulate the conditions and processes of the modern oceans and to allow predictions. The environmental changes arising from human activity since the 18 th century (also called the Anthropocene) have made the Earth System even more complex. Anthropogenic activities have altered both terrestrial and marine ecosystems, and the legacy of these impacts in the oceans include: a) pollution of the marine environment by solid waste, including plastics; b) pollution by chemical and medical (including those for veterinary use) substances such as hormones, antibiotics, legal and illegal drugs, leading to possible endocrine disruption of marine organisms; and c) ocean acidification, the collateral effect of anthropogenic emissions of CO 2 into the atmosphere, irreversible in the human life time scale. Unfortunately, the anthropogenic alteration of the hydrosphere due to inputs of plastics, metal, hydrocarbons, contaminants of emerging concern and even with formerly "exotic" trace elements, such us rare earth elements is likely to accelerate in the near future. These emerging contaminants would likely soon present difficulties for studies in pristine environments. All this knowledge brings with it a great responsibility: helping to envisage viable adaptation and mitigation soluti...
