Current human health risk assessments of soil arsenic (As) contamination rarely consider bioaccessibility (IVBA), which may overestimate the health risks of soil As. The IVBA of As (As-IVBA) may differ among various soil types. This investigation of As-IVBA focused As from geological origin in a typical subtropical soil, lateritic red soil, and its risk control values.

- This study compares two amaranth cultivars, Quanhong (QH) and Liuye (LY), to investigate how salinity affects cadmium (Cd) accumulation.
- LY, identified as a high-Cd accumulator, exhibited significantly more differentially expressed genes (DEGs) under salt stress, indicating greater sensitivity to salinity compared to QH.
- Findings reveal that salinity enhances Cd mobilization in LY through increased expression of specific genes while simultaneously inhibiting crucial enzymes related to root barriers, highlighting the health risk of salt-sensitive crops.
Article Synopsis
- Biogas slurry (BS) is a nutrient-rich byproduct of biogas production often used in agriculture, but it can lead to crop quality issues and accumulation of harmful substances like nitrates and heavy metals.
- A study using microalgae (Scenedesmus sp.) found that mixing BS with tap water at a 50% ratio effectively removed major pollutants and improved growth conditions for the microalgae.
- Irrigating Chinese cabbage with microalgae-treated BS resulted in healthier crops with better nutritional quality and taste while reducing harmful residues, suggesting this approach could safely utilize BS in farming.
Article Synopsis
- Chinese flowering cabbage can easily absorb cadmium (Cd) from contaminated soil, raising concerns for food safety, leading researchers to explore low-Cd cultivars as a solution.
- A study screened 37 cultivars to identify their Cd accumulation levels under different soil conditions, revealing significant variability in shoot Cd concentrations among them.
- The study highlighted that the root-to-shoot (R/S) ratio of the cultivars was a key factor influencing Cd accumulation, with lower R/S ratios linked to reduced Cd levels in the shoots, suggesting a potential method for selecting low-Cd cultivars.
Exogenous Glycinebetaine Promotes Soil Cadmium Uptake by Edible Amaranth Grown during Subtropical Hot Season.

Exogenous glycinebetaine treatment is an effective measure for preventing crops from being exposed to drought and high temperature; however, the effects of this approach on the soil Cd uptake and accumulation by crops remain unclear. Pot experiments were conducted in this study to analyze the effect of glycinebetaine on the soil Cd uptake and accumulation by edible amaranth cultivated in Cd-contaminated soil. Results revealed that after exogenous glycinebetaine treatment on amaranth leaves during the vigorous growth period, the plant biomass, the Cd concentrations in the roots and shoots, and the Cd translocation factor (TF) were significantly higher than those of the control group.

- Reclaimed tidal flat soils often contain high salinity and heavy metal accumulation, which can pose health risks when consuming vegetables grown in these conditions.
- Previous studies identified low-cadmium (Cd) tomato cultivars in non-saline soils and, to ensure their safety, research was conducted to assess their performance in saline soils with heavy metal pollutants.
- Results indicated that cherry-type tomatoes accumulated more heavy metals like Cd, zinc (Zn), and copper (Cu) than common types, but both low-Cd cultivars showed low metal concentrations in their fruits, partly due to specific growth characteristics that reduced metal uptake.*
This study aimed to investigate the difference of osmoregulation between two edible amaranth cultivars, Liuye (high Cd accumulator) and Quanhong (low Cd accumulator), under salinity stress and determine the effects of such difference on Cd accumulation. A pot experiment was conducted to expose the plants to sewage-irrigated garden soil (mean 2.28 mg kg Cd) pretreated at three salinity levels.
