“…56 A study showed that pollutants in plants were mainly caused by human activities, such as industrial sewage, domestic sewage, and agricultural wastewater, which was summarized by cluster analysis and principal component analysis. 57 Some plants could accumulate huge amounts of nitrates, 58 polycyclic aromatic hydrocarbons, 59 antibiotics 60 or other pharmaceutical chemicals, 61,62 trace metals, 57 and radioactivity from wastewater. 63 Although the resulting concentration of contaminants in the soil exceeded the environmental quality standards, their presence in plants might meet the food safety guidelines and would not affect the chlorophyll and carbohydrate contents in the leaves, 64 which explained normal growth of our tested plants.…”

Effect of Ultrafiltration–Reverse-Osmosis-Treated Shale Gas Wastewater on Seed Germination and Plant Growth

The safe disposal or reclaim of shale gas flowback and produced water (SGFPW) is a significant challenge given the large amounts and typically heavy contamination. The high levels of total dissolved solids, particulate matter, and organics combined with naturally occurring radioactive material (NORM) and heavy metals reflect the composition of SGFPW, bearing potential environmental hazards of bioaccumulation of contaminants in localized areas of shale gas wastewater disposal. This study investigated the effects of ultrafiltration–reverse-osmosis-treated shale gas wastewater on vegetable seed germination, plant growth performance, and ion concentration in plants, which offered a momentous exploration of the feasibility study on agricultural use for SGFPW reuse. The resulting uptake of heavy metals by vegetables is relatively low, and the radioactive elements are reduced to a safe level as a result of treating water used for irrigation, selecting appropriate crops, and greenhouse cultivation. Through reduction of the bioaccumulation and metal concentrations from SGFPW to plants, this approach decreases health risks associated with NORM intake from edible vegetable biomass.

“…Many WWTPs do not attain 99% removal efficiency of microplastics in China (Lin et al, 2018); for example, a municipal WWTP equipped with activated sludge techniques in Wuhan only removed about 64.4% of microplastics (Liu et al 2019). Another issue is that 60% of polluted sludge from WWTPs in China is disposed of in landfill sites (Sun et al, 2019). Microplastics can leach from landfills and find routes through soils to contaminate freshwaters (He et al, 2019).…”

A critical review of microplastic pollution in urban freshwater environments and legislative progress in China: recommendations and insightsFreshwater systems are vitally important, supporting diversity and providing a range of ecosystem services. In China, rapid urbanization (over 800 million urban population) has led to multiple anthropogenic pressures that threaten urban freshwater environments.Microplastics (<5 mm) result from intensive production and use of plastic materials, but their effects in urban freshwater environments remain poorly understood. Rising concerns over the ecological effects of microplastics have resulted in increased attention being given to this contaminant in Chinese freshwater systems. Some studies provide quantitative data on contamination loads, but in general relevant knowledge in freshwater environment remains narrow in China, and lacking adequate understanding of threshold levels for detrimental effects. Notably, non-standardized sample collection and processing techniques for point and non-point sources have hindered comparisons of contamination loads and associated risk. Meanwhile, legislative frameworks for managing microplastics in China remain in their infancy. This manuscript critically reviews what is known of the nature and magnitude of microplastic pollution in Chinese freshwater environments, and summarises relevant Chinese legislation. It provides recommendations for improving the legislative framework in China and identifies research gaps that need to be addressed to improve management and regulatory strategies for dealing with microplastic pollution in Chinese urban freshwater environments.

“…Different human activities such as fuel, wood and coal burning, industrial effluents discharges, oil extraction, and ship traffic [7][8][9][10][11] comprise the primary PAH sources, responsible for the input of about 200 compounds belonging to the PAH group into the environment [12]. High PAH concentrations have been detected in sediments, rivers, and fishes [3].…”

Background: Polycyclic aromatic hydrocarbons (PAHs) are persistent pollutants routinely detected in aquatic ecosystems. It is, therefore, necessary to assess the link between deleterious marine biota PAH effects, especially in commercialized and consumed animals, environmental health status, and potential human health risks originating from the consumption of contaminated seafood products. Thus, this review seeks to verify the relationships of ecotoxicological studies in determining effect and safety concentrations on animals routinely consumed by humans. Methods: A total of 52 published studies between 2011 and 2021, indexed in three databases, were selected following the PICO methodology, and information on test animals, evaluated PAH, and endpoints were extracted. Results: Benzo(a)pyrene and phenanthrene were the most investigated PAHs in terms of biomarkers and test organisms, and mussels were the most evaluated bioindicator species, with an emphasis on reproductive responses. Furthermore, despite the apparent correlation between environmental PAH dynamics and effects on aquatic biota and human health, few assessments have been performed in a multidisciplinary manner to evaluate these three variables together. Conclusions: The links between human and environmental sciences must be strengthened to enable complete and realistic toxicity assessments as despite the application of seafood assessments, especially to mussels, in bioassays, the connection between toxicological animal responses and risks associated with their consumption is still understudied.
