Heavy metal toxicity impacts multiple organ systems through oxidative stress and inflammation. Natural compounds like curcumin and quercetin demonstrate protective effects, while nanotechnology enables sensitive detection and efficient removal. Food crops account for 90% of human exposure, emphasizing certification importance.

This study detected widespread nickel contamination in Portuguese premade baby foods, with levels often exceeding EFSA’s safety thresholds, particularly in organic products. The findings underscore the need for regulatory limits and comprehensive heavy metal testing within the baby food industry.

Nickel contact dermatitis in children is rising due to widespread exposure from jewelry, clothing, and devices. Effective regulation, rigorous testing, and clear labeling are essential for prevention and management, as sensitization persists and avoidance is challenging. Certification programs must prioritize testing and consumer education.

This review finds that children’s exposure to dietary nickel often exceeds safe limits, especially from chocolate, cereals, and soy-based foods, with potential health risks. It underscores the need for monitoring, regulation, and clear guidance to protect vulnerable populations from nickel overexposure.

This review demonstrates that dietary nickel triggers dermatitis in sensitized individuals, details clinical evidence, and offers practical dietary management strategies. It underscores the need for regulation of nickel exposure from food, water, and cookware for heavy metal certification program

This review synthesizes research on low-level heavy metal exposure and its adverse effects on male reproductive health, highlighting risks from cadmium, lead, mercury, and essential trace metals, with implications for certification and regulation.

A comprehensive review of molecular mechanisms underlying Group 1 metal-induced carcinogenesis, highlighting genotoxic, epigenetic, and signaling pathways relevant for heavy metal certification and regulatory standards.

This review underscores the global health burden of heavy metal exposure, detailing acute and chronic effects, vulnerable populations, and diverse exposure routes. It emphasizes under-recognition in clinical practice, contamination in consumer goods, and the urgent need for certification, monitoring, and international cooperation to protect public health.

This large Korean cohort study found that even low-level prenatal cadmium exposure is significantly associated with reduced birth weight, underscoring the need for stringent cadmium limits in heavy metal certification programs to protect fetal health.

This systematic review identifies Klebsiella and Enterobacter as the most promising plant-associated bacteria for bioremediation of arsenic, cadmium, and lead, emphasizing the importance of both molecular and biochemical resistance mechanisms for heavy metal certification programs.
