Microplastic pollution has become pervasive. Identifying a bioindicator species to track the occurrence and effects of microplastics (MPs) on ecosystems is crucial for determining their impact environment. The digestive tract Procambarus clarkii was thought be interest investigating MPs accumulation in freshwater organisms. Our hypothesis that same type found abiotic compartments (water sediment) could P. clarkii, which would make it an ideal candidate use as MP ecosystems. Water, sediment, specimens were collected from four sites lentic ecosystem (Lake Candia; northwestern Italy) two consecutive years (2021–2022). mean abundance 1.75 ± 0.95 items/m3 2021 2 0.81 2022 water samples 6.75 1.5 items/kg 8 sediment 2022, respectively. In 2021, average 0.06 0.07 items/g males 0.05 females; 0.04 females, fibers fragments (black, white, blue, light blue) polypropylene polyethylene terephthalate biotic compartments. generalized linear mixed model revealed number predicted only by total weight: lowest recorded crayfish with highest weight probably due feeding habits clarkii. findings suggest invasive (smaller individuals, particular) good since items Further research needed better understand behavior dynamics aquatic

Microplastics in Freshwater Sediments Impact the Role of a Main Bioturbator in Ecosystem Functioning

Environmental Science & Technology, Год журнала: 2023, Номер 57(8), С. 3042 - 3052

While microplastic transport, fate, and effects have been a focus of studies globally, the consequences their presence on ecosystem functioning not received same attention. With increasing evidence accumulation microplastics at sediment–water interfaces there is need to assess impacts engineers, also known as bioturbators, which direct indirect health. This study investigated impact bioturbator Tubifex tubifex alongside any biogeochemical processes interface. Bioturbators were exposed four sediment concentrations: 0, 700, 7000, 70000 particles kg–1 dry weight. Though no mortality was present, significant response oxidative stress detected in tubificid worms after exposure medium concentration (7000 weight). accompanied by reduction worm bioturbation activities assessed ability rework stimulate exchange water fluxes Consequently, contributions organic matter mineralization nutrient significantly reduced microplastics. demonstrated that environmentally realistic concentrations had an interface reducing worms.
