Special Issue Information

Dear Colleagues,

Two of the most pressing challenges to human health are environmental pollution and food safety. Environmental pollution (e.g., heavy metals and legacy persistent organic pollutants) has historically harmed food safety, posing serious hazards to human health. Although international and national regulatory agencies have developed control measures and policies for pollutants in the environment and in food, food safety remains threatened by an increasing number of emerging pollutants; Therefore, this Special Issue is committed to presenting the latest scientific developments and important findings in the contamination of the environment, crops and food by emerging environmental pollutants.

This Special Issue welcomes high-quality articles in the field of ‘Food Environmental Pollution Monitoring, the Transfer of Hazardous Materials in Soil–Crop Plant Systems and a Risk Assessment of Emerging Contaminants in Food'.

Cadmium (Cd) pollution in paddy soils causes a great threat to safe rice production in China. In this review, we summarized the key advances in the research of Cd pollution sources and statuses in Chinese soil and rice, explore the mechanisms of Cd transformation in the rice–soil system, discuss the agronomic strategies for minimizing Cd accumulation in rice grains, and highlight advancements in developing rice cultivars with low Cd accumulation. Anthropogenic activity is a main source of Cd in farmland. Cd in soil solutions primarily enters rice roots through a symplastic pathway facilitated by transporters like OsNRAMP5, OsIRT1, and OsCd1, among which OsNRAMP5 is identified as the primary contributor. Subsequently, Cd translocation is from roots to grains through the xylem and phloem, regulated by transporters such as OsHMA2, OsLCT1, and OsZIP7. Meanwhile, Cd sequestration in vacuoles controlled by OsHMA3 plays a crucial role in regulating Cd mobility during its translocation. Cd accumulation in rice was limited by the available Cd concentration in soil solutions, Cd uptake, and translocation in rice plants. Conventional agronomic methods aimed at reducing grain Cd in rice by suppressing Cd bio-availability without decreasing soil Cd content have been proven limited in the remediation of Cd-polluted soil. In recent years, based on the mechanisms of Cd absorption and translocation in rice, researchers have screened and developed low-Cd-accumulation rice varieties using molecular breeding techniques. Among them, some new cultivars derived from the null mutants of OsNRAMP5 have demonstrated a more than 93% decrease in grain Cd accumulation and can be used for applications in the next years. Therefore, the issue of Cd contamination in the rice of China may be fully resolved within a few years. Full article
