However, less than 10% was recycled. Moreover, most conventional plastics are persistent and, therefore, remain in the environment long after their release. Although most studies on microplastic contamination focus on a single environmental compartment, an integrated and multicompartment approach is highly recommended considering the multitude of interactions between those compartments. This study addresses this knowledge gap, investigating the presence and potential sources of microplastics (MP) in agricultural soils under typical conditions of the Mediterranean region, characterised by dry summers and relatively moist and mild winters (Csa according to the Köppen-Geiger classification). For this, 19 orchards from east-central Portugal were used as case study sites, and a total of 111 samples were analysed. Soil content in MP was assessed in 3 soil layers (0–5, 5–15 and 15–25 cm). To quantify potential sources to soil, information from farmers was used, and samples from irrigation water, atmospheric deposition and manure were analysed. Optical assessment with the assistance of a stereomicroscope was used for MP quantification. The 0–5 cm soil layer showed a lower content (average of 2.2 particles·g⁻¹) and higher particle sizes (average of 168 µm) than deeper soil layers. The identified sources contributed with 1.02 × 10⁵ particles·m⁻²·year⁻¹. Irrigation water was the main source, representing 55.9% of the aforementioned input rate encountered for the 3 identified MP sources. Additional knowledge is needed regarding the possible variation in MP content throughout the year and between years and the polymer identification, not only in samples collected from soil but also from its main contamination sources. Furthermore, this study should be extended to other crops and regions as part of broader soil health monitoring.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 6","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10661-025-14072-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143929927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

This is the first study to analyze the abundance of MP in the compost leachate from one of the Isfahan compost plant (S1), located in one of Iran’s major cities with high population density, during the summer season. MPs were counted using a stereomicroscope, and fourier transform infrared spectroscopy (FTIR) was utilized to identify polymer types. The results revealed an average abundance of MPs in the S1 leachate during the summer of 992.66 ± 100.85 items/L. Over 62% of the MPs identified in this study fell within the 1000–5000 μm size range, with a concentration of 610.28 ± 59.26 items/L. Polystyrene and polyamide emerged as the most frequently identified polymers (18.46% and 16.8%), and fragments were the most commonly observed shape among the MPs.

The Indicators of Hydrologic Alteration—Range of Variability Approach method (IHA-RVA) was applied to calculate the degree of hydrologic alteration after the dam impoundment. Then, the Spearman correlation method is used to identify a number of key indicators driving shifts in species composition. Results indicate that fish species richness increased during the early impoundment phase of the Three Gorges Dam, corresponding with rising water levels. However, following the operation of the Xiangjiaba Dam, species richness began to decline. The traditionally dominant Cyprinidae family has diminished in prevalence, while taxonomic diversity and community complexity have increased. Rheophilic species remain dominant, though the proportion of limnophilic species has risen, now constituting nearly 50% of the total species composition. Altered hydrological conditions, particularly increased long-term dry season flow, have emerged as key drivers of changes in fish community structure.
