As these particles infiltrate various habitats, they are ingested by a wide range of organisms, from plankton to large marine mammals. The ingestion of MPs disrupts the food web, causing physical and chemical harm to animals at multiple trophic levels. Here, we studied the accumulation of MPs in the gastrointestinal tracts (GITs) of a terrestrial lizard species after long-term monitoring using museum specimens in the collection of the Fauna and Flora Research and Application Center at Dokuz Eylül University from decades ago. These museum samples were from 1986 to 2013, but not consecutive years. GITs from 300 individuals were analyzed and MPs were detected in the GITs of only 25 individuals. In 25 individuals, the most dominant form of microplastic was fiber. The highest number of MPs was detected in 2001, followed by 1995. It is thought that this accumulation is caused by human activities in the lizard's environment and that it enters the food web indirectly because it lives in areas with high human interaction. Overall, this study shows that MPs have been present in the past, entering the food web of terrestrial species, and that MPs can inherently transfer to other living things. It is understood that MPs will pose significant threats to biodiversity and ecosystem health as they are transferred through the food chain.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":546,"journal":{"name":"Environmental Sciences Europe","volume":"37 1","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s12302-024-01042-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142939264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although these substances can enter the aquatic environment directly through bathing, authorisation for use in cosmetic products does not require a specific environmental risk assessment, whereas risks to human health are specifically assessed. Furthermore, no environmental quality standards have been proposed at EU level. For the current review, data on freshwater ecotoxicity, physicochemical properties, environmental fate and measured exposure were retrieved from ECHA registration information and public databases and assessed for reliability and relevance. Environmental quality standards (EQS) were proposed based on the EU technical guidance for EQS for the Water Framework Directive (WFD).</p><h3>Results</h3><p>From a WFD perspective, there were significant or complete gaps for acute and chronic effects data, sediment organisms and rarely tested organisms at the time of data retrieval, as well as gaps for measured environmental concentrations in the assessed databases.

To address this, we conducted a field experiment involving five tobacco varieties (K326, K394, XL, Y87, and Y97) and two types of soil (continuous cropping obstacle soil and normal soil). We examined microbial responses to different tobacco varieties in each soil type. Our results revealed that soil available nutrients and organic matter were decreased in obstacle soil compared to normal soil. The fresh biomass decreased by 18.05–27.92% in obstacle soil (except K394 and Y97). The microbial community composition in the rhizosphere soil remained consistent in various tobacco varieties in obstacle soil. The connections between soil fertility nutrients and microbial communities were reduced in obstacle soil compared to normal soil. The alteration of bacterial community composition was a stochastic process, whereas the modification of fungal community composition was a deterministic process in obstacle soil. Furthermore, the abundance of differential fungi (Zoopagomycota) was notably higher in obstacle soil. Overall, our results revealed that the disturbance of microbial communities and soil degradation in the obstacle soil are primary factors contributing to reduced crop yields.
