[Adverse Effects and Underlying Mechanisms of Soil Microplastics on Crops and Its Preventive Strategies].

Microplastics （MPs）, as a type of emerging environmental pollutant with a particle size < 5 mm, have been frequently detected in environmental matrices. MPs pollution in soils has been attracting the scientific community due to the increasing contaminant areas and continuous accumulation, leading to a high risk to crop production. In addition, recent studies have observed that long-term exposure to MPs could seriously harm the soil ecosystem because of their fine particle size and persistence in soils.

Psychological resilience and related factors among primary care workers in Wuhan, China: A cross-sectional study.

Purpose: Primary medical workers constitute a high-risk group for mental health problems, and psychological resilience might protect them from the negative psychological impacts of their work. Therefore, this study aimed to investigate the current situation of psychological resilience among primary care workers in Wuhan, China, as well as related factors.

Methods: In this cross-sectional study, a total of 417 primary care workers (30.

Heavy metal(loid)s in agriculture soils, rice, and wheat across China: Status assessment and spatiotemporal analysis.

Heavy metal(loid)s (HMs) accumulation in agricultural soils, rice, and wheat is of particular concern in China, while the status and spatio-temporal distribution of HMs in the soil-crops system have been rarely reported at the national scale. This study aimed to summarize the overall pollution status, spatiotemporal patterns, and drivers of HMs in agricultural soil, rice, and wheat nationwide. The metal-polluted data from 1030 agricultural soils, rice, and wheat in China were collected from the literature published from 2000 to 2022.

The oral bioaccessibility and gingival cytotoxicity of metal(loid)s in wild vegetables from mining areas: Implication for human oral health.

Background: Heavy metal(loid)s are frequently detected in vegetables posing potential human health risks, especially for those grown around mining areas. However, the oral bioaccessibility and gingival cytotoxicity of heavy metals in wild vegetables remain unclear.

Methods: In this study, we assessed the total and bioaccessible Cr, As, Cd, Pb, and Ni in four wild vegetables from mining areas in Southwest China.

Heavy metal(loid)s in agricultural soil from main grain production regions of China: Bioaccessibility and health risks to humans.

Unintentional ingestion of metal-contaminated soils may pose a great threat to human health. To accurately evaluate the health risks of heavy metal(loid)s in soils, their bioaccessibility has been widely determined by in vitro assays and increasingly employed to optimize the assessment parameters. Given that, using meta-analysis, we analyzed the literature on farmland heavy metal(loid)s (As, Cd, Cr, Cu, Hg, Pb, Ni, and Zn) in Chinese main grain production regions, and collected their total and bioaccessibility data to accurately assess their human health risks.

Removal of Cr (VI) by Biochar Derived from Six Kinds of Garden Wastes: Isotherms and Kinetics.

Garden waste is one of the main components of urban solid waste which affects the urban environment. In this study, garden waste of (SS), (BY), (LS), (YS), (GH) and () (CB) was pyrolyzed at 300 °C, 500 °C, 700 °C to obtain different types of biochar, coded as SSB300, SSB500, SSB700, BYB300, etc., which were tested for their Cr (VI) adsorption capacity.

Mechanisms of Cd and Cu induced toxicity in human gastric epithelial cells: Oxidative stress, cell cycle arrest and apoptosis.

Cadmium (Cd) and copper (Cu) are widely present in foods. However, their adverse effects on human gastric epithelium are not fully understood. Here, human gastric epithelial cells (SGC-7901) were employed to study the toxicity and associated mechanisms of Cd + Cu co-exposure.
