“…However, there are some indications that MPs adversely affect algae in a concentration and size-dependent manner [41][42][43]. For instance, 1 μm PVC fragments inhibited the growth and negatively affected photosynthesis (50 mg L À1 ) of the marine algae Skeletonema costatum [43], while 1 mm PVC fragments did not induce such alterations.…”

The ubiquitous detection of microplastics in aquatic ecosystems promotes the concern for adverse impacts on freshwater ecosystems. The wide variety of material types, sizes, shapes, and physicochemical properties renders interactions with biota via multiple pathways probable.So far, our knowledge about the uptake and biological effects of microplastics comes from laboratory studies, applying simplified exposure regimes (e.g., one polymer and size, spherical shape, high concentrations) often with limited environmental relevance. However, the available data illustrates species-and materialrelated interactions and highlights that microplastics represent a multifaceted stressor. Particle-related toxicities will be driven by polymer type, size, and shape. Chemical toxicity is driven by the adsorption-desorption kinetics of additives and pollutants. In addition, microbial colonization, the formation of heteroaggregates, and the evolutionary adaptations of the biological receptor further increase the complexity of microplastics as stressors. Therefore, the aim of this chapter is to synthesize and critically revisit these aspects based on the state of the science in freshwater research. Where unavailable we supplement this with data on marine biota. This provides an insight into the direction of future research.In this regard, the challenge is to understand the complex interactions of biota and plastic materials and to identify the toxicologically most relevant characteristics of the plethora of microplastics. Importantly, as the direct biological impacts of This chapter has been externally peer reviewed.

“…In physical terms, MPs can influence water (e.g., translucency [42]), sedimentation (e.g., feces [95]), and sediment (e.g., thermal conductivity [96]) characteristics. In ecological terms, MPs can affect the aquatic biocoenosis on a large scale (Fig.…”

“…Similar results were obtained for a green alga Scenedesmus obliquus exposed to polystyrene (PS; 0.07 µm particle size) by Besseling and co-workers (Besseling et al, 2014), who reported ~3% inhibition rate at 1000 mg/L and non-significant effects at lower concentrations. However, for another green alga Dunaliella tertiolecta, even lower concentrations of similar test material (PS; particle size 0.05 µm, 250 mg/L) caused a severe growth inhibition (57%) (Sjollema et al, 2016). However, the effect mechanisms for nanoparticles are likely to be different from the micrometer-sized particles, as shown for nanoparticle-cell interactions that involve extracellular proteins in the algal cell membrane with downstream effects on nutrient acquisition (Yue et al, 2017) or changes in colloidal stability affecting bio-physical interactions with cell walls (Gonzalo et al, 2014).…”

“…So far, most efforts have focused on animal responses to microplastic exposure (Foley et al, 2018;Ogonowski et al, 2018b), whereas far less research addressed possible effects of microplastic on primary producers (Yokota et al, 2017). The reported consequences of the interactions between primary producers and particles of fossil-based polymers in nano-and microparticle size range include alterations in algal photosynthesis (Bhattacharya et al, 2010), growth (Sjollema et al, 2016;Bergami et al, 2017a), and colony morphology (Yokota et al, 2017). These effects are important as they can propagate in the food web, affecting consumers and system productivity.…”

Hazard assessment of microplastic is challenging because standard toxicity testing is mostly developed for soluble (at least partially) chemicals. Adverse effects can occur when test organisms are exposed to turbid environments with various particulate matter (PM), both natural, such as sediment, and anthropogenic, such as microplastic. It is, therefore, relevant to compare responses to PM exposure between the microplastic and other suspended solids present at ecologically relevant concentrations; this can be done by using reference materials when assessing hazard potential of microplastics. Here, we evaluated growth inhibition in unicellular alga Raphidocelis subcapitata exposed to different suspended solids (microplastic, kaolin, and cellulose; 10, 100 and 1000 mg/L) during 72 h; algae without added solids were used as a control. In addition, aggregate formation in the exposure systems was analyzed using particle size distribution data. At 10 and 100 mg/L, no adverse growth effects were observed in any treatments; moreover, algal growth was significantly stimulated in kaolin and cellulose treatments compared to the control. However, at 1000 mg/L, all tested materials exerted growth inhibition, with no significant differences among the treatments. The comparison among particle size distributions across the treatments showed that both PM concentration and size of the particle aggregates were significant growth predictors for all materials tested. Therefore, at high concentrations, both natural and anthropogenic materials have similar capacity to cause adverse effects in algal growth inhibition tests, which must be taken into account in hazard assessment of plastic litter.

“…Prata (2018) menciona que microplásticos têm mostrado reduzir o processo fotossíntetico e crescimento de microalgas, provocado efeitos negativos na cadeia alimentar de zooplâncton, que acumula e possivelmente provoca sequelas em brânquias, estômago e hepatopâncreas de caranguejos e induz alterações nos tecidos e biomarcadores de peixes. Estudo realizado por Sjollema et al (2016) corroba que microplásticos afetam os processos fotossíntéticos e crescimento de microalgas.…”

RESUMOOs plásticos são lançados no ambiente de diferentes maneiras, podendo ser degradados por fatores abióticos e bióticos. Entretanto, quando degradadas, as partículas de dimensões na escala micro e nanoplásticas, podem se acumular no ambiente, gerando uma série de fatores hostis à flora e fauna, principalmente nos organismos. Dessa maneira, esse artigo tem como objetivo fornecer informações relevantes sobre as possíveis fontes de inserção de partículas plásticas no ambiente, bem como potencial efeito sobre os organismos. Para tal, foi realizado uma busca de artigos científicos na área da pesquisa, cadastrados em bases de dados, da comunidade científica. Nota-se que nas últimas décadas houve uma acentuada expansão de pesquisas relacionadas aos efeitos dos nano e microplásticos sobre os organismos vivos, pois esses polímeros quando presentes no ambiente podem afetar direta ou indiretamente à saúde, ecologia e economia. As consequências à saúde são em decorrência da adsorção, que posteriormente pode causar efeitos tóxicos letais aos indivíduos. Dada a crescente necessidade de detecção de nano e microplásticos no ambiente, isso se torna um grande desafio, pois, embora muitos estudos utilizem técnicas amplamente semelhantes, ainda não existe um protocolo padrão. Diante desse impasse, muitos estudos estão identificando novos critérios e relatos mais consistentes. Em suma, estudos relativos a nano e microplásticos ainda são incipientes, necessitando de mais pesquisas para preencher as lacunas existentes. PALAVRAS-CHAVE:Polímeros, resíduos, saúde.
