Heavy Metal-Contaminated Soils and Gastric Cancer Risk: Molecular Insights and the Relevance of a One Health Perspective

mycolabadmin

Heavy metals like cadmium, arsenic, and lead contaminate agricultural soils and accumulate in crops such as rice and vegetables, which people consume as part of their daily diet. These metals damage stomach cell DNA and trigger inflammation, increasing cancer risk, especially when combined with bacterial infections like H. pylori. A comprehensive approach monitoring soil quality, crop safety, and human health together can help prevent this disease and protect communities from contamination.

Soil health alterations via compost additions to natural and remediated heavy metal-contaminated mineland soils

mycolabadmin

Abandoned mining sites in Missouri left contaminated soils that couldn’t support plant growth. Researchers tested whether adding compost could restore these soils to health comparable to natural prairie. They found that applying 180 tons of compost per hectare successfully restored soil quality and plant growth while keeping heavy metal levels safe for livestock, making it an effective and affordable solution for healing mining-damaged lands.

Cadmium and Lead Tolerance of Filamentous Fungi Isolated from Contaminated Mining Soils

mycolabadmin

Researchers isolated six types of fungi from mining-contaminated soil in Mexico that can survive in extremely toxic environments with high levels of lead and cadmium. These fungi have developed special strategies to handle these dangerous metals, with one species, Paecilomyces lilacinus, showing exceptional ability to tolerate both metals simultaneously. These findings suggest these fungi could be used to clean up contaminated soils in mining regions, offering hope for environmental remediation efforts.
