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.

This research reveals that heavy metals in commercial baby foods, especially aluminum and zinc, can exceed safety thresholds. Contamination is linked to soil and food type, not packaging, underscoring the need for enhanced monitoring and industry regulation for infant food products.

This study found that most commercially available fruit juices in Lahore, both local and imported, contained heavy metals—especially lead, nickel, and chromium—at levels greatly exceeding WHO limits, signaling urgent need for enhanced HTMC regulation and industry compliance.

Heavy metal soil pollution reshapes the plant mycobiome by altering symbiotic associations rather than simply reducing soil fungal diversity, highlighting the need for certification programs to integrate biological and chemical assessments for a more accurate evaluation of ecosystem health.
