The MercuNorth study provides essential baseline data on mercury exposure in pregnant Arctic women, highlighting regional disparities and temporal declines. Findings support the need for integrated biomonitoring and dietary assessment in heavy metal certification and regulatory initiatives.

Blood mercury concentrations in the U.S. population show marked demographic variability, with Asians and older adults exhibiting the highest values. These findings provide critical reference data for heavy metal certification and risk management.

This study recalculates safe maternal methylmercury intake using pregnancy-specific data, finding lower intake thresholds than current EPA standards. The updated model enables more precise and protective percentile-based regulatory limits for HTMC programs.

This review analyzes arsenic in drinking water, focusing on the 10μg/L WHO guideline, health risks, regulatory evolution, and technological challenges. It highlights scientific uncertainties and the implications for heavy metal certification and industry standards.

Early-pregnancy blood mercury at moderate levels showed no adverse birth outcomes; fish-eating increased mercury but correlated with slightly better anthropometrics, informing HTMC limits and guidance.

This study shows that pregnancy triggers release of lead stored in maternal bones, increasing fetal exposure even when environmental sources are minimal. Endogenous lead mobilization can elevate blood lead levels, emphasizing the need for heavy metal certification programs to account for internal as well as external exposures.

This review highlights the CDC’s approach to blood lead prevalence studies, detailing their significance for heavy metal certification, study design, laboratory methods, and policy implications, with global examples for context.

Review of Ayurvedic medicine heavy metal poisoning, highlighting prevalence, toxicology, standardization gaps, and HTMC-aligned testing priorities for safe certification.

This study revealed dangerously high lead levels in traditional kohl cosmetics sold globally, highlighting risks to children and regulatory gaps.

Evidence shows ground turmeric lead contamination, high bioaccessibility, recalls, and US regulatory gaps. HTMC can set limits, enforce lot testing, and audit supply chains to prevent adulterated spices.
