Abstract

The integration of data on environmental microplastic concentrations, in vivo concentrations within organisms, and organism tolerance is poorly known. This study introduces the tolerance value (TV) and in vivo microplastic concentrations as factors to monitor and analyze the bioaccumulation and toxicity of microplastics. The bioaccumulation of microplastics in wild Cipangopaludina chinensis and Semisulcospira libertina in the Songhua River was investigated. The bioaccumulation and effects on biochemical markers were subsequently examined over a 28-day period. The findings revealed that the concentration of microplastics in C. chinensis (32.37 ± 6.03 items/g) is higher than that in S. libertine (22.81 ± 12.72 items/g). Prolonged exposure led to acetylcholinesterase activity inhibition and notable abnormalities in redox and energy metabolism markers. S. libertina exhibited a lower TV (TV=3.1), and greater sensitive to microplastics (sensitivity coefficient=0.73), making it a better indicator organism. In contrast, C. chinensis (TV=5.4) accumulates greater pollutant loads but shows reduced sensitivity (sensitivity coefficient =0.48). This study addresses the gap in understanding the differential bioaccumulation and biological responses to microplastics in freshwater species, providing new insights into species-specific pollutant burdens and sensitivities, and highlighting the advanced use of S. libertina as a novel indicator organism for microplastic pollution assessment.

期刊介绍： The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice. PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers. PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
