As the innovation in modelling, the spatial weight matrix was based on three-dimensional coordinates with a modification on the height factor. The data we used are real-time data of water level on the peatlands in Pulang Pisau Regency, Central Kalimantan Province from 20 February 2021 to 18 March 2023. We then used Ordinary Kriging interpolation on the prediction results to create contour maps on different dates. There were empty data on several dates, especially from 24 March until 3 August 2022. To fill the empty data, we used linear interpolation and then we added white noise to the interpolation results. From the data, the water level has a downward trend pattern from around November to September and an upward trend pattern from October to November. Furthermore, we found that the best model for water level was GSTAR (2;0.1) with a modified matrix <span>(a=0.1)</span> and <span>(b=1.1)</span>. Based on the predicted water level, there is a risk of changes in the properties of the peatlands in several areas in Pulang Pisau Regency.</p></div>","PeriodicalId":546,"journal":{"name":"Environmental Sciences Europe","volume":"36 1","pages":""},"PeriodicalIF":6.0,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s12302-024-00979-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142434918","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}

Aquaculture and fisheries provide a means of livelihood to an estimated 58.5 million people globally, according to the United Nations Food and Agriculture Organisation. However, the sector is impacted by the ubiquity of microplastics and toxic chemicals. Although many studies have reported plastic pollution in the aquaculture environment, less attention has been paid to the coexistence of toxic chemicals with plastic particles and the role of climate change in aquaculture food contamination. This review evaluates the occurrence of microplastics in organisms, feeds, water, and sediment in the aquaculture ecosystem and the detection and hazardous effects of toxic chemical contaminants. We also highlight novel insights into the role of climate change in plastic and chemical contamination of aquaculture organisms and ecosystems. We report that the extent of aquaculture’s contribution to global climate change and global plastic pollution is yet to be adequately quantified and requires further investigation for appropriate risk assessment and prevention of food safety crisis. Possible mitigation strategies for the highlighted pollution problems were suggested, and some identified gaps for future research were indicated.

This paper concentrates on the Inde River, where lignite mining led to the relocation of a 5-km-long river section.

The assessment of the cooling potential showed that convection heat gains make it difficult to create an all-year round cooling material. The comparison with a conventional building material, a concrete roof tile, hence shows great potential for these RC materials as heating gains during summer are significantly reduced.
