Microplastics inside bodies: contamination of MPs in Phallusia nigra
AI summary Read the abstract
Researchers investigated microplastic contamination in Phallusia nigra, a sessile marine invertebrate ascidian that filter-feeds via inhalant and exhalant siphons and commonly inhabits artificial coastal structures, harbors, and ship hulls in warm waters from Bermuda to Brazil. The study examined P. nigra as a potential bioindicator for microplastic pollution given its proximity to coastal contamination sources and existing use as a sentinel species for heavy metals and organic pollutants.
Ascídias são invertebrados marinhos sésseis, tanto solitários quanto coloniais. Possuem sifões inalantes e exalantes conectados ao cesto branquial para funções de respiração e alimentação. Esses animais habitam ambientes costeiros e estuarinos e sua distribuição é determinada pela temperatura, salinidade e hidrodinâmica. Phallusia nigra é uma espécie comum distribuída em águas quentes que vão desde Bermudas (32N) até São Sebastião, Brasil, e outras regiões como Mar Vermelho, Golfo de Áden e Golfo da Guiné. P. nigra se fixa em substratos artificiais e naturais, mas prefere plataformas de ancoragem, estruturas portuárias e cascos de navios. Esta proximidade com áreas costeiras e fontes de poluição expõe P. nigra a uma série de contaminantes. Esta espécie tem sido investigada como bioindicadora de poluição por metais pesados e compostos orgânicos. Sua potencial bioindicação para mercúrio e compostos aromáticos policíclicos foi relatada, incluindo o potente composto mutagênico 3-nitrobenzatrona e seus metabólitos.

Rising tide of microplastics: contamination in filter-feeding ascidians
AI summary Read the abstract
Researchers assessed microplastic contamination in filter-feeding ascidians, which serve as bioindicators in marine pollution monitoring and evolutionary biology models. Microplastics were detected in ascidian tissues, with accumulation patterns reflecting local water contamination levels.
Detection of Microplastic Contamination in Shallow Marine Habitats Using Solitary Ascidians: Influence of Morphology and Habitat in a Tropical Bay, SW Atlantic
AI summary Read the abstract
A study of four ascidian species in Ilha Grande Bay, Brazil found that Styela plicata, with simple tentacles and branchial folds, retained significantly more microplastic particles than species with different morphologies, and contamination was higher near harbors and in winter. Filter-feeding invertebrates serve as effective bioindicators of local plastic pollution sources, and their morphological variation influences how much microplastic accumulates in marine food webs.
