“…Microplastics enter freshwater environments through various routes including discharge of domestic wastewater [10], application of sludge from wastewater treatment plants in agriculture [11], landfill leachate [12], surface run-off (little is known about transport by run-off ), and atmospheric deposition [13]. Previous studies have shown that once in the aquatic environment, microplastics are ingested by a range of organisms, with further impact due to the leaching of toxic plastic additives including bisphenols and Open Access *Correspondence: luzhibo@tongji.edu.cn 1 College of Environmental Science and Engineering, Tongji University, Shanghai 200092, China Full list of author information is available at the end of the article phthalates [14,15]. As for processes, there is insufficient understanding of appropriate sampling and analysis techniques for microplastics in freshwater [9], with variations in methodology hindering comparisons of study results.…”

Background: The Yangtze Estuary acts as gateways where microplastics transport from freshwater into marine environments, with one of the largest discharge volumes in the world. The occurrence of microplastics in surface water and sediments of the Yangtze Estuary has been reported. However, little is known about microplastics in and around Chongming Island in the estuary. In this study, the distribution of microplastics in surface water and sediments of Chongming Island was investigated and compared in different environmental medium.Results: Abundances of microplastics in surface water and sediments were in the ranges of 0-259 items m − 3 and 10-60 items kg − 1 dry weight, respectively. Microplastics were more abundant in the surface water of the Yangtze River shores than in the inland rivers (p < 0.01). Proportions in fiber form in surface water and sediment were 33% and 67%; and those in fragment form were 39% and 24%. Most particles (> 72%) were < 1 mm in the longest dimension; 65% were white and 30% were transparent. Of the 11 compositions identified, polyethylene, polypropylene, and α-cellulose predominated in both phases.Conclusion: This is the first study to focus on microplastics in inland watercourses on Chongming Island and along the Yangtze River's shores in both phases. There were differences between the island and estuary in composition and density due to the distinct vertical mixing processes. The in situ filtration of surface water (100 L) sampling method was well employed in various freshwater environments and free of plastic materials in front of the filter, analysis results of which provided an important baseline reference for evaluating microplastic pollution in the Yangtze Estuary.

The distribution and abundance of microplastics into the world are so extensive that many scientists use them as key indicators of the recent and contemporary period defining a new historical epoch: The Plasticene. However, the implications of microplastics are not yet thoroughly understood. There is considerable complexity involved to understand their impact due to different physical–chemical properties that make microplastics multifaceted stressors. If, on the one hand, microplastics carry toxic chemicals in the ecosystems, thus serving as vectors of transport, they are themselves, on the other hand, a cocktail of hazardous chemicals that are added voluntarily during their production as additives to increase polymer properties and prolong their life. To date, there is a considerable lack of knowledge on the major additives of concern that are used in the plastic industry, on their fate once microplastics dispose into the environment, and on their consequent effects on human health when associated with micro and nanoplastics. The present study emphasizes the most toxic and dangerous chemical substances that are contained in all plastic products to describe the effects and implications of these hazardous chemicals on human health, providing a detailed overview of studies that have investigated their abundance on microplastics. In the present work, we conducted a capillary review of the literature on micro and nanoplastic exposure pathways and their potential risk to human health to summarize current knowledge with the intention of better focus future research in this area and fill knowledge gaps.

“…e performance of WAS anaerobic fermentation is closely related to the microbial community structure and microbial abundance of the sludge system [35,51]. In order to better explore whether DEHP has a potential influence on microbial community structure, the Illumina Hiseq16S DNA genes technique was used to conduct a comparative analysis of microbial communities in two long-term reactors (control reactor: without DEHP; DEHP reactor: DEHP concentration is 100 ppm).…”

“…Existing WWTPs are being scaled up to satisfy the needs of a growing city, resulting in more and more WAS [35]. Anaerobic fermentation of WAS can produce energy biogas methane and achieve sludge reduction while minimizing the number of pathogenic microorganisms in the sludge [35][36][37][38]. A large number of microorganisms, such as acetogens, hydrogenogens, and methanogens, are linked to the anaerobic fermentation process of WAS [1,39,40].…”

Diethylhexyl phthalate (DEHP) is a common plasticizer in industrial production. Recently, environmental problems caused by microplastics have drawn wide attention. As the microplastics have a large specific surface area, the release rate of the plasticizer from the microplastics to the environment is accelerated. e DEHP in the wastewater enters the wastewater treatment plants (WWTPs) along with the urban pipeline. After DEHP enters the WWTPs, it may affect the anaerobic fermentation with waste activated sludge (WAS) as raw material. So far, there has been no study on the effect of DEHP on anaerobic fermentation of WAS. Our study focused on the impact of exogenous DEHP on WAS anaerobic fermentation, and the results showed that DEHP mainly affects the solubilization stage of sludge anaerobic digestion, but has no significant effect on other stages. It does not affect the total yield and composition of short-chain fatty acids (SCFA). However, DEHP inhibited the solubilization process of WAS anaerobic fermentation, which was mainly manifested by the changes of soluble protein and soluble polysaccharide in the system. e results of the analysis of microbial communities revealed that the addition of DEHP did not change the diversity of microbial communities, but caused a change in the abundance of microbial organisms. DEHP reduced the abundance of acetogen bacteria and increased the abundance of methanogens. is work provides some insights into WAS fermentation systems in the presence of DEHP and helps to gain a better understanding of the potential environmental hazards of microplastics.
