This review highlights how exposure to heavy metals and nanoparticles disrupts the gut microbiota, with implications for human and animal health. The findings underscore the need for stringent heavy metal certification programs using advanced biomarker monitoring.

This review demonstrates that prenatal and early childhood exposure to lead, mercury, cadmium, and arsenic is consistently linked to neurodevelopmental harm, underscoring the need for stringent heavy metal limits in certification and regulation, especially for products targeting pregnant women and children.

This study quantified toxic metals and metalloids in Brazilian infant formulas, revealing generally low health risks except for arsenic, which exceeded recommended thresholds in most products. The findings underscore the need for enhanced heavy metal certification and regulatory oversight, particularly for arsenic contamination.

This lead exposure assessment among pregnant women and children in Karachi, Pakistan, identifies food and house dust as the primary lead sources, emphasizing the need for targeted interventions and rigorous testing for effective heavy metal certification and public health protection.

This systematic review demonstrates that heavy metal contamination in TCMs is common and poses significant health risks, especially for vulnerable populations. Rigorous testing and certification are crucial for safe regulation and effective consumer protection.

This review synthesizes how omics technologies advance our understanding of heavy metal stress alleviation through plant-microbiome interactions, enabling precision bioremediation and supporting evidence-based heavy metal certification programs.

This study found that higher dietary fiber intake is significantly associated with lower serum cadmium and lead—but not mercury—levels in US adults consuming recommended seafood amounts, suggesting fiber’s potential role in reducing certain heavy metal burdens relevant for certification programs.

This review links higher blood copper and cadmium, and lower zinc and manganese, to increased breast cancer risk, underscoring the need for specimen-specific heavy metal certification standards and further research to inform regulatory guidelines in public health.

Keystone microbial taxa in heavy-metal-contaminated soils possess diverse resistance genes and plant growth-promoting traits, providing a genetic foundation for bioremediation and informing heavy metal certification programs.

High-fat diets impair gut microbiota’s capacity to detoxify heavy metals, resulting in increased organ accumulation and toxicity. Specific gut microbes, such as Lactobacillus, play a key role in fecal excretion of heavy metals, highlighting implications for dietary interventions in heavy metal certification programs.
