The samples were collected from three site categories: port, residential area, and aquaculture floating net cages. Water quality in each site was also observed. Three marine animals with different feeding regimes were selected to assess MPs contamination, including pompano (<i>Trachinotus blochii</i>), crab (<i>Ocypode kuhlii</i>), and oyster (<i>Crassostrea</i> sp.). A series of extraction protocols followed by stereomicroscope observation were conducted to identify the MPs' abundance, form type, and color. Next, the MPs polymer type was characterized using Fourier Transform Infra Red (FT-IR) at a frequency range 4000–400 cm-1 resolution 4.0 with Bruker Alpha II spectrometer. The results showed no significant difference (P &lt; 0.5) in MPs abundance in water (15.75–20 part.L⁻¹) and sediment (10.25–12.3 part.kgDW⁻¹) samples between the sites as well as between marine animals (23.20–27.03 part.ind⁻¹). Various MPs types and color proportions were observed from water and sediment from different sampling locations and marine animal body parts. The MPs form types found include fragment (6–58%), film (7–49%), fiber (2–25%), and pellet (20–78%), while based on the MPs particle colors, the proportion were black (14–78%), yellow (7–33%), blue (2–25%), red (8–30%) and green (2–30%). Analysis of functional groups and polymers from water, sediments, and marine animal samples indicated the presence of PS (Polystyrene) and PE (Polyethylene). The study results indicated widespread MP contamination in the Kodek Bay area. The results serve as a scientific-based recommendation for policymaking to further prevent MPs contamination in the area.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142579529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study also finds that some other formal institutional factors, which include marketization, the development of intermediate organizations, the legal system environment, and GDP levels, have moderating effects on the impact of distrust environment on corporate sulfur dioxide emissions. In addition, climatic conditions including temperature, humidity, and precedence, as well as the location of the enterprise, have certain moderation effects. Mechanism analysis indicates that distrust environment affects corporate sulfur dioxide emissions through the increase in coal sulfur content in enterprise production, the decrease in exhaust gas processing capacity, the reduction in financing capacity, and the decline in social and environmental responsibilities.

Especially, the simultaneous extraction of several analyte groups from sediment samples is currently uncommon, but from the perspective of green analytical chemistry, it is highly desirable. In simultaneous analysis, multiple groups of substances are determined at once instead of through several individual analyses, saving energy, time, and chemicals while significantly increasing laboratory throughput. This review reports different approaches for monitoring the presence of environmental contaminants from four different groups of contaminants from river sediments. There are plenty of sampling techniques, with the core and grab sampling being the most employed at present. Sample preparation is a challenging part of the whole analytical method, providing ample opportunity for optimization in accordance with green analytical chemistry principles. Various extraction schemes, including ultrasound-assisted extraction techniques, accelerated solvent extraction, and microwave-assisted extraction are energy-intensive techniques but may be considered \"green\" due to their possibility to reduce the consumption of organic solvents, which are usually considered toxic. Quick, Easy, Cheap, Effective, Rugged and Safe extraction (QuEChERS) in the case of satisfactory validation parameters is well-evaluated and utilized. The most recent developments in extraction and clean-up techniques for simultaneous analysis of two, three or four groups of contaminants are showing promising results. Separation and detection techniques are shortly discussed. Further optimizations of analytical methodologies are needed, and future developments in the field of analytical methods for sediment samples are expected for more efficient and faster acquisition of data on the presence of contaminants in real monitoring samples.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11270-024-07559-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142555210","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}
