EFSA lowers cadmium tolerable intake to a TWI of 2.5 µg/kg bw/week, based on renal biomarkers and European exposure data, guiding HTMC controls.

Long-term exposure to airborne cadmium, nickel, and lead significantly increases cardiovascular mortality. Findings stress revising regulatory limits and incorporating heavy metal testing in certification systems like HTMC.

This review summarizes how AEGLs for four hazardous airborne chemicals were established, focusing on acute exposure scenarios using robust toxicological and regulatory methodologies highly relevant for heavy metal certification programs.

Chronic arsenic exposure in Taiwan, Chile, and Bangladesh induces vascular, metabolic, and respiratory dysfunction via oxidative and inflammatory pathways, revealing biomarker-linked mechanisms essential for improving heavy metal certification and regulatory policies.

This study assessed heavy metal content in milk and milk products in Poland, finding levels generally below EU limits. Results support certification feasibility, but highlight the need for continued monitoring, especially for lead, to protect children and maintain safety standards for HTMC programs.

Aluminum exposure is a critical factor in dialysis-associated anemia. The review underscores the need for strict heavy metal certification of water and medical products to prevent reversible, aluminum-induced hematological complications in renal patients.

Zinc-induced copper deficiency from over-the-counter supplements can cause severe anemia and neutropenia. This case study underscores the importance of regulatory oversight and careful supplement review for heavy metal certification programs.

Chronic zinc supplementation caused reversible copper deficiency anemia in an 18-year-old, revealing critical metabolic interactions and diagnostic markers vital for HTMC heavy metal certification standards.

The study shows arsenic depresses brain monoamines and elevates NO, while curcumin partially reverses these changes, clarifying mechanisms and mitigation relevance for HTMC exposure controls.

This review synthesizes data on lead exposure and neurodevelopment, establishing a health-based threshold of 0.5 µg/kg bw/day to inform risk assessment and certification standards for heavy metals in maternal and child health contexts.
