Biotic ligand modeling (BLM) approaches are already applied to predict the bioavailability and possible risk of metals in surface water, but need further development for soils. The present study investigated the effect of major cations (Ca, Mg, Na, K, and H) on cadmium bioaccumulation in the springtail Folsomia candida. To avoid the complexity of real soils and enable control of elemental speciation in the exposure medium, the animals were exposed to different cadmium concentrations in an inert quartz sand-solution medium. Accumulation of cadmium in the animals was measured after 7 days exposure at different cation concentrations. Among the cations, only Ca significantly affected the uptake of cadmium in the springtails. Mg also had higher effects compared with other selected cations. Using a BLM approach, the uptake of cadmium in the animals predicted by taking into account both Ca and Mg activities correlated well with the measured values (R = 0.68). The final estimated conditional binding constants for cadmium (log K), Ca (log K), and Mg (log K) of 1.06, 2.14, and 1.23 L/mol, respectively, were in agreement with previously reported values. The match between predicted and measured uptake data confirms the applicability and usefulness of the BLM for predicting the bioavailability of cadmium to springtails and opens the way for its application in soil.

Cocoa-growing areas in Ghana have experienced a rise in mining activities affecting cocoa cultivation and increased concentrations of potentially toxic metals in the soil, which can accumulate in cocoa beans. This study evaluated potential toxic metal contamination in cocoa beans and soils from cocoa farms in mining and non-mining areas in Ghana. We used X-ray fluorescence and an ICP-MS to determine metal concentrations, and a Zeeman mercury analyzer to determine mercury.

Rice (Oryza sativa L.) is a staple food for half of the world's population, and its biofortification is a key factor in fighting micronutrient malnutrition. However, harmful heavy metals tend to accumulate in rice grains due to soil and water contamination.

This study aims to investigate the ability of cadmium (Cd) accumulation in Peristrophe bivalvis cultivated in a pot experiment for 60 days at various Cd amounts of 0, 20, 60, and 100 mg/kg. Throughout the experiment, no toxic effects were observed, and the presence of Cd did not inhibit the growth of the plants. A linear correlation coefficient (P < 0.

Cadmium (Cd) contamination presents a serious challenges for sustainable agriculture. This study evaluated the combined impact of arbuscular mycorrhizal fungi (AMF) inoculation and intercropping with Solanum nigrum on soil microbial diversity, enzyme activity, and environmental factors in soybean cultivation under high Cd stress. The combined treatment effectively reduced bioavailable Cd in soil, with the acid-soluble Cd fraction at 19.
