Summary: The supply of sulfate has been found to reduce the bioavailability of arsenic (As) and cadmium (Cd) in paddy soil contaminated with both metals. The effect of sulfate addition, however, varies depending on the soil environment, potentially due to differences in sulfate background levels. Additionally, the addition of sulfate stimulates the activity of sulfate-reducing bacteria, which can positively affect rice growth and physiological characteristics.

Summary: This study investigates the effects and mechanisms of elevated CO2 concentration on cadmium (Cd) uptake by rice in a 3-year experiment. The results show that increased CO2 concentration leads to higher levels of dissolved Fe2+ in soil, resulting in more low-crystalline Fe oxides being deposited on the root surface. This inhibits the uptake of Cd by rice.

Summary: This study investigated the effect of oxygen nanobubbles on the growth and uptake of arsenic in rice. The results showed that oxygen nanobubbles increased rice biomass, chlorophyll content, and promoted plant photosynthesis under arsenic stress. Additionally, they decreased the arsenic content in rice roots and shoots, ultimately reducing arsenic accumulation in rice.

Summary: Soil sulfate amendment and intermittent flooding can effectively decrease the accumulation of inorganic arsenic (iAs) in rice grains. Continuous flooding, regardless of sulfate amendment, leads to rice straighthead disease and increased accumulation of dimethylarsenate (DMA) in grains. The study indicates the importance of combining sulfate amendment and intermittent flooding for improving rice yield and quality in arsenic-affected areas.

Summary: This study evaluated the effects of climate change on the accumulation and bioavailability of Cd and Pb in rice plants and paddy soils. The results showed that climate change accelerated the accumulation of Cd and Pb in rice grains, increased the bioavailability of Cd and Pb in soil, and affected the composition of soil bacterial communities. It was also found that climate change significantly increased the carcinogenic risk for children and adults, posing a major risk to future safe rice production.

Summary: The field experiment aimed to study the transport and uptake of arsenic in rice plants, as well as to assess the human health risk associated with arsenic exposure through rice consumption. Results showed that the average total As concentrations in the experimental site and brown rice were 93.02 mg/kg and 0.158 mg/kg, respectively. The study found a significant negative linear relationship between inorganic As concentration in brown rice and partition ratio values, suggesting potential cancer and non-cancer risks for Taiwan residents.

Summary: Planting rice in As-contaminated paddy soils can lead to As accumulation in rice grains, which can be aggravated by P fertilizers. However, remediation using Fe(III) oxides/hydroxides cannot effectively reduce grain As and maintain P fertilizer utilization simultaneously. In this study, schwertmannite was proposed as a remedy for flooding As-contaminated paddy soil due to its strong sorption capacity for As and its positive effect on P fertilizer utilization. The results showed that the application of schwertmannite along with P fertilization effectively reduced As mobility in the contaminated soil and increased soil P availability. Moreover, it reduced P content in Fe plaque on rice roots, benefiting P fertilizer utilization. The amendment of schwertmannite and P fertilizer together significantly reduced As content in rice grains and increased rice shoot biomass, achieving the dual goals of reducing grain As and maintaining P fertilizer utilization efficiency.

Summary: Rice production generates residues of straw and husk, and managing these residues is crucial for the sustainability of rice agroecosystems. Rice straw is usually either incorporated into the soil or burned before incorporation, while rice husk is not typically returned to rice fields. Adding rice straw instead of burned straw increased soil iron and arsenic, plant arsenic, and methane emissions regardless of husk addition. Despite its high silicon concentration, husk addition had insignificant effects on plant silicon, indicating limited short-term mobility of silicon and the need for further studies on long-term husk addition or higher rates.

Summary: This study investigates the regulatory roles of selenite and selenate on the uptake, translocation, and transformation of arsenite or arsenate in rice plants. The results show that selenite promotes root uptake of arsenite but reduces its translocation, while selenate increases the uptake and translocation of arsenate. The presence of iron plaque does not significantly affect the interaction between selenium and arsenic in rice plants.

Summary: This study investigated the effects of gallium (Ga) and indium (In) on the growth and uptake of wheat plants. It found that aluminum toxicity in wheat seedlings increased with Ga and In concentrations in acidic soils, and indium phytotoxicity was present in both neutral and acidic soils. The concentration of Ga and In in roots was approximately one order of magnitude higher than in the shoots of wheat seedlings, and Ga had a higher translocation capability from roots to shoots compared to In.

Summary: This study found that under flooded conditions, the concentrations of inorganic arsenic in soil pore water and water spinach increased significantly compared to upland conditions. Despite higher Fe plaque formation on root surfaces under flooded conditions, it was not effective in preventing arsenic uptake by the plant tissue. Consequently, the dietary risk of consuming inorganic arsenic through water spinach grown in flooded soils was higher than in upland soils.

Summary: The study on the effects of rice husk biochar and cattle manure compost on a sandy loam rural soil in southern Taiwan showed that both amendments promoted soil aggregation and enriched soil organic carbon. The addition of compost further enhanced organic carbon enrichment in microaggregates and mesoaggregates, suggesting their potential role in enhancing carbon sequestration.
