“…The application of fertilizers with beneficial metal elements can effectively reduce the enrichment of HM elements in morels by antagonizing HM ions on the cell wall, as HM sites on the cell wall of morels are not specific [31,32]. For example, Yu, et al [159] demonstrated that P fertilizer significantly increased soil pH and available P while decreasing soil available HM concentrations. Additionally, Zhou, et al [160] effectively passivated Cu, Zn, and As by adding 3% Fe 2 (SO 4 ) 3 to pig manure, which led to a decrease of 82.35% and 80.00% in available Cd and Pb concentrations, respectively [161].…”

Morel is a popular edible mushroom with considerable medicinal and economic value which has garnered global popularity. However, the increasing heavy metal (HM) pollution in the soil presents a significant challenge to morels cultivation. Given the susceptibility of morels to HM accumulation, the quality and output of morels are at risk, posing a serious food safety concern that hinders the development of the morel industry. Nonetheless, research on the mechanism of HM enrichment and mitigation strategies in morel remains scarce. The morel, being cultivated in soil, shows a positive correlation between HM content in its fruiting body and the HM content in the soil. Therefore, soil remediation emerges as the most practical and effective approach to tackle HM pollution. Compared to physical and chemical remediation, bioremediation is a low-cost and eco-friendly approach that poses minimal threats to soil composition and structure. HMs easily enriched during morels cultivation were examined, including Cd, Cu, Hg, and Pb, and we assessed soil passivation technology, microbial remediation, strain screening and cultivation, and agronomic measures as potential approaches for HM pollution prevention. The current review underscores the importance of establishing a comprehensive system for preventing HM pollution in morels.
