Contaminant accumulation analysis is important in the study of sentinels. This research determined cadmium accumulation and bioconcentration factors of whole organism, liver, kidney, ovary and testis of Fejervarya limnocharis exposed to different environmental cadmium levels. Frogs from contaminated sites had significantly higher hepatic (1.939 mg/kg), renal (7.253 mg/kg) and testicular (1.462 mg/kg) cadmium than those from the reference sites (0.205, 0.783 and 0.379 mg/kg, respectively). Cadmium accumulation was the highest during the late dry and early rainy seasons. If this species is used as a sentinel for cadmium accumulation, the utilization of its whole organism, liver, kidney and testis is appropriate.

The coexistence of microplastics and heavy metals in soil can lead to more intricate environmental effects. While plant growth-promoting bacteria have been widely recognized for enhancing the remediation of heavy metal-contaminated soils, little research has been conducted to investigate whether they can alleviate the stress of microplastic-heavy metal composite contamination on plants. We investigated the effects of isolated and screened plant growth-promoting bacteria on the growth and cadmium (Cd) accumulation of under the composite pollution of Cd and polypropylene (PP) with different particle sizes (6.

To clarify the characteristics of Cd, As, and Pb concentrations in edible parts of crops and farmland soils, a key farmland survey was conducted on the field scale to investigate the characteristics of Cd, As, and Pb in soil and chili pepper (edible parts in the above-ground section) and sweet potato (edible parts under the ground) and assess the health risk of Cd-As-Pb in edible parts of chili pepper and sweet potato to humans in the typical co-contaminated agricultural soils by Cd, As, and Pb from metal smelting and sewage irrigation in North China. The results showed that the agricultural soil from chili pepper and sweet potato fields was co-contaminated by Cd and As at a moderate pollution level. The combined pollution index (2.

Heavy metals (HMs) pollution in agricultural soil-rice systems has attracted worldwide attention as it directly threatens regional ecological security and human health. To understand the heavy metal pollution of agriculture soil and rice in the high geological background areas, a total of 200 paddy soil and rice samples were collected in southeast Chongqing. The concentrations of arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb), and zinc (Zn) in paddy soil and rice were analyzed.

Soil cadmium (Cd) contamination is a non-negligible global environmental issue as it may threaten food security and human health through soil-plant interactions. Nanomaterials have a great potential to decrease Cd bioavailability and bioaccumulation, even though the effects have been inconsistent among various studies. Here we compiled data from 137 experiments on the remediation of Cd-contaminated soils by nanomaterials.

Cadmium (Cd) is a genotoxic heavy metal causing severe toxicity symptoms in plants, which has been a major threat to worldwide crop production. Recently, nanoparticles (NPs) have been employed as a novel strategy to facilitate the Cd stress and act as nano-fertilizers directly. Therefore, this study aims to explore the effects of zinc oxide nanoparticles (ZnONPs; 15 mg/L) on plant growth, photosynthetic activity, antioxidant activity and root morphology in Capsicum chinense Jacq.
