The Plastiverse Extends to Hydrogeologic Systems: Microplastics Are an Important Emerging Groundwater Contaminant Class

“…2021; Zhu et al. 2022). Some researchers have modified biochar through the addition of various (magnesium, zinc, and iron), metal oxides (e.g., iron oxide), and oxidizing agents (e.g., nitric acid, sulfuric acid) to improve sorption, reactive functional groups, mobility, colloidal stability, and sustainability (Magid et al.…”

“…Relative to spongebased and metal-based absorbents, biochar, because of its porous morphology and active vacant sites on its surface, is more suitable and less expensive than spongebased and metal-based adsorbents for the adsorption MPs (Magid et al 2021). Biochar can be prepared by several different methods (e.g., pyrolysis, carbonization, and impregnation) using a variety of biomass types (e.g., sugarcane bagasse, corncobs) (Ganie et al 2021;Singh 2021;Wang et al 2021;Zhu et al 2022). Some researchers have modified biochar through the addition of various (magnesium, zinc, and iron), metal oxides (e.g., iron oxide), and oxidizing agents (e.g., nitric acid, sulfuric acid) to improve sorption, reactive functional groups, mobility, colloidal stability, and sustainability (Magid et al 2021;Singh 2021;Wang et al 2021).…”

Photo-oxidation of Micro- and Nanoplastics: Physical, Chemical, and Biological Effects in Environments

“…Currently, several reviews have summarized the weathering processes of MPs and corresponding effects on the environmental behavior of MPs, mainly considering the different weathering processes and mechanisms, and the effect of weathering on the properties, adsorption, and toxicity of MPs. ,− However, few of them have thoroughly considered the physical, chemical, and biological effects of photo-oxidation of MNPs in the environment. In the last two years, an increasing number of studies have focused on understanding the process of photo-oxidation and its impact on different types of MNPs, as well as the effect of environmental constituents on this process. ,,,− Furthermore, research on the influence of photo-oxidation of MNPs on the adsorption and photochemical transformation of other pollutants has gained more attention. − The biological effect of photo-oxidized MNPs on organism activity, especially microbial community composition and function has also become a subject of interest among scholars. ,, More importantly, the photo-oxidation process and the physical, chemical, and biological behavior of MNPs are mutually associated and inseparable. Thus, it is necessary to give a critical review of recent research on the physical, chemical, and biological effects of photoaged MNPs in aquatic and terrestrial environments.…”

Do Added Microplastics, Native Soil Properties, and Prevailing Climatic Conditions Have Consequences for Carbon and Nitrogen Contents in Soil? A Global Data Synthesis of Pot and Greenhouse Studies

“…30,36−38 Many MP types (including polyacrylic, polyamide, polyester, polyethylene, biodegradable polylactic acid) have been found to markedly influence soil properties, including C and N contents. 9,10,29,32,4 To date, most studies have reported that MPs caused reduction in soil N content while increasing Cmineralization and leading to higher CO 2 emissions. 39,40 MPs descend into the soil profile, where they appear in various shapes, sizes, and compositions.…”
