Trends and drivers of global dietary methylmercury exposure during 1995–2020
Methylmercury (MeHg) exposure primarily comes from diet, posing serious health risks. However, the trends of global dietary MeHg exposure and underlying drivers remain unknown. This study reveals the recent global trend in dietary MeHg exposure (expressed in per capita probable daily intake of MeHg), and the sources and drivers of exposure changes. Results show that global dietary MeHg exposure has increased by 29 % during 1995–2020, especially in South Asia (203 %), Southeast Asia (104 %), and Sub-Saharan Africa (77 %). Freshwater fish consumption was the main source for increased MeHg exposure. The increase in food consumption was the main driver of the growth in global dietary MeHg exposure, while dietary structure transition was the primary driver of its decline. The changes in MeHg concentrations of foods have mitigated dietary MeHg exposures in developed economies, but aggravated them in underdeveloped economies. Our findings can guide decision-making on managing increasing dietary MeHg exposure.
期刊介绍：
The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns.
Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
