Journal ArticleDOI
TL;DR: In this paper, a review on the nature of available wastes, different strategies for its breakdown or hydrolysis, efficient microbial systems, and some representative examples of biomasses source that are used for bioenergy production by providing critical information are discussed.

Journal ArticleDOI
TL;DR: In this paper, the authors explored the scenarios of arsenic contamination in groundwater with an emphasis on public health concerns and demonstrated arsenic sources, biogeochemistry, toxicity mechanisms with therapeutic targets, arsenic exposure-related human diseases, and onsets of cardiovascular diseases as well as feasible management options for arsenic toxicity.

Journal ArticleDOI
TL;DR: Wang et al. as discussed by the authors used sample data to assess both soil and crop heavy metal risks, in order to explore the differences between heavy metal contamination risks in soil and crops as well as the relationships between heavy metals contents in soil, and crops.

Journal ArticleDOI
TL;DR: In this article, the authors discuss the abundance, distribution, adsorption, and desorption behavior of microplastic polymers for heavy metals, and their combined toxic effects on flora and fauna based on the limited research on this topic in the literature.

Journal ArticleDOI
TL;DR: This review aims to provide an updated overview of this emerging topic, reviewing the literature mainly from 2018 onwards and considering the effects of nanoplastics on ecosystems, their uptake and transport of polluting molecules, and the challenges that are faced by workers in this area.

Journal ArticleDOI
TL;DR: In this article, the authors evaluated the ability of new and used disposable face masks of different types to release microplastics into the water and found that the microplastic release capacity of the used masks increased significantly from 183.00 −78.42 particles/piece for the new masks to 1246.62 −403.50 particles/ piece.

Journal ArticleDOI
TL;DR: A sustainable selective mitigation method should be considered concerning the economic resources available, the ability of infrastructure to sustain water treatment, and the options for reuse and/or safe disposal of treatment residuals.

Journal ArticleDOI
TL;DR: Variation analyses of MP characteristics revealed that cereal crop farmlands (wheat, paddy land) were more likely to contain fibrous shapes and large MP particles (1-5 mm), and Economically important tree lands (orchards, woodlands) were likely to containing fragment shapes and pony-size MPs (0.02-0.2 mm).

Journal ArticleDOI
TL;DR: More than one billion nanoplastics and microplastic particles were released from each surgical or N95 face mask in the COVID-19 pandemic and most of them were nano scale sized as discussed by the authors.

Journal ArticleDOI
TL;DR: The Lijiang River was found to have a high accumulation of Cd, Hg, Zn, and Pb in the sediments, and the midstream area was the most polluted with respect to Cd and Hg and posed a relatively higher potential ecological risk than the downstream and upstream areas.

Journal ArticleDOI
TL;DR: This work on marine ecosystem health indicator species will provide valuable and comparable information in the future, and advice and best practices on research into the exposure and impact of microplastics in marine mammals are discussed.

Journal ArticleDOI
TL;DR: Results demonstrate the relatively modest contribution of traffic to air quality, suggesting that sustained improvements in air quality require actions across various sectors, including working with international and European initiatives on long-range transport air pollutants, especially PM2.5 and O3.

Journal ArticleDOI
TL;DR: ZVI and Fe3O4 NPs can be used as Fe-fertilizers to improve rice growth under Fe-deficient condition, which exist in many rice-growing regions of the world, however, dose should be carefully chosen as high dose of the Fe-based NPS can impair rice growth.

Journal ArticleDOI
TL;DR: In this article, the influence of foliar-applied nanoplastics on crop growth and nutritional quality was investigated in soil-grown lettuces (Lactuca sativa L).

Journal ArticleDOI
TL;DR: Based on collected data from China's rice cultivation dominated regions, this paper provided the Cd pollution level of paddy soils and rice grains in China and found that the Yangtze River basin, especially Hunan, required more attention due to the elevated Cd concentrations in soil-rice ecosystems.

Journal ArticleDOI
TL;DR: The detected microplastic concentrations did not exceed the derived PNEC, i.e., the current pollution levels of fragment and fiber microplastics in the size range 20-300 μm would not pose a significant threat to the marine ecosystem in South Korea.

Journal ArticleDOI
TL;DR: It is confirmed that the aging process could enhance the potential of MPs as vectors for ARGs, which would promote the holistic understanding of MP behavior and risk in natural environments.
