Challenges for utilization and management of crop straw from Cd‐contaminated soil

Soil health and ecosystem services

“…Heavy metals such as cadmium in agricultural soil represents one of the biggest threats to human health (Arao et al, 2010; Qin et al, 2023), and crops have particularly high rates of cadmium uptake (Dong et al, 2022; Zhang, Tan, et al, 2022). Open burning of contaminated straw or its usage as livestock feed can further increase exposure risks via inhalation or ingestion of meat and milk.…”

Intercropping with herbs minimizes cadmium availability through altering physicochemical dynamics and metabolite profiles in wheat rhizosphere

“…Cadmium (Cd) pollution has become an important issue related to environment and public health worldwide, and gradually threatens agricultural food safety and human health (Murakami et al, 2009; Wang et al, 2021; Wiggenhauser et al, 2016). The World Health Organization (WHO) has placed Cd in their top 10 chemicals of major public concern, with one of the main exposure pathways being the ingestion of contaminated foodstuff (Dong et al, 2022); 7% farmlands were contaminated by Cd according to a recent nationwide survey of soil contamination in China (Kang, Wang, et al, 2020; Liu et al, 2016; MEP of China [Ministry of Environment Protection of China], 2014). Wheat has always been the main crop in North Asian countries, but wheat plants have a high absorption of cadmium, which may have an adverse impact on public health.…”
