“…However, it was slightly higher than other studies in Cambodia (12.7 µg/kg, range: 9.9-16.7 µg/kg) (Cheng et al, 2013). For MeHg concentration in rice, our results showed higher mean concentration than that in Cambodia (1.54 µg/kg) and some mercury mining in China, such as Guangdong (1.2 µg/kg) and Guizhou (5.7 µg/kg), but it was far lower than in Wanshan (30.4 µg/kg) and Danzhai (20.8 µg/kg) as summarized in the previous study (Zhao et al, 2019). Some studies reported Hg concentrations in rice around ASGM area in other parts of Indonesia, but Hg in fish was discussed as the main concern instead of rice.…”

“…The mean THg concentration (1.6 µg/kg, range: 1.3-2.4 µg/kg) was far below the Indonesian National Standard. Moreover, this results also lower than other commercial rice reported in Sri Lanka (1.73 µg/kg, range: 0.21-6.13 µg/kg) (Xu et al, 2020), China (4.47 µg/kg, range: 1.06-22.7 µg/kg) (Zhao et al, 2019), Pakistan (4.51 µg/kg, range: 0.44-157 µg/kg) (Aslam et al, 2020), and Cambodia (8.14 µg/kg, range: 6.16-11.7 µg/ kg) (Cheng et al, 2013). It means that commercial rice in Indonesia is still in a safe level based on Indonesian National Standard for THg in cereals.…”

“…To date, there were no reliable studies evaluated the Hg intake in Indonesian general population on rice consumption. This estimation value was far lower than general population reported in Sri Lanka (0.015 µg/kg/day) (Xu et al, 2020), China (0.0056 µg/kg/ day (MeHg), range: 0.0012-0.0134 µg/kg/day) (Zhao et al, 2019), and Kratie, Cambodia (12.6 µg/kg/day) (Cheng et al, 2013). Even though Indonesian rice consumption rate was considerably high in Asia, the THg concentrations in rice were very low for the general population.…”

“…The MeHg intake ranged from 0.01-0.21 µg/kg/day which constituted about 95% of the total MeHg exposure to residents in Wanshan Hg mining area, China. Other than that, the average daily rice consumption in China was reported to be lower than Indonesian daily consumption (Zhao et al, 2019;Liu et al, 2019).…”

Artisanal and Small Scale Gold Mining (ASGM) contributes as the biggest source of mercury (Hg) emission in Southeast Asian countries including Indonesia. Rice paddies are the most impacted agriculture area caused by Hg emission from ASGM sewage water. It may pose to health risk effect to humans due to the consumption of the rice as the staple food. This study was aimed to evaluate the Hg accumulation in rice and health effect to residents in Lebaksitu ASGM area by analysis of total mercury (THg) and methylmercury (MeHg) in hair. Two villages were selected in this study, Hg hotspot village (Lebak-1) and low Hg exposure village (Lebak-2). The THg concentration in rice ranged from 9.1-115 µg/kg with an average of 32.2 µg/kg. MeHg concentration in rice constituted 14.7-81.8% of the THg. Rice in Lebak-1 had higher THg and MeHg concentrations than those in Lebak-2. The mean THg and MeHg concentration in hair were 3.2 mg/kg and 1.78 mg/kg, respectively. Residents in Lebak-1 had significantly higher THg and MeHg in hair than those collected from Lebak-2. The MeHg ratio to THg in hair varied widely ranged from 15.68-92.43%. There was a significant correlation between high intake of MeHg from rice and the accumulation of MeHg in the hair. It was concluded that rice is the potential source of MeHg exposure to humans through daily consumption in rice consumer countries.

“…Following previous studies 16,41 , we did not consider rice from Hg-contaminated sites in the material flow analysis since previous studies suggested that rice from Hg-contaminated sites was locally consumed 14,55 , and amounts of rice produced in most Hg-contaminated sites are unknown. For example, researchers found that THg and MeHg concentrations in commercial rice were generally not high in markets across China 56 . A similar situation was also found in other regions, such as Europe 24 .…”

Rice life cycle-based global mercury biotransport and human methylmercury exposure

et al. 2019

Protecting the environment and enhancing food security are among the world’s greatest challenges. Fish consumption is widely considered to be the single significant dietary source of methylmercury. Nevertheless, by synthesizing data from the past six decades and using a variety of models, we find that rice could be a significant global dietary source of human methylmercury exposure, especially in South and Southeast Asia. In 2013, globalization caused 9.9% of human methylmercury exposure via the international rice trade and significantly aggravated rice-derived exposure in Africa (62%), Central Asia (98%) and Europe (42%). In 2016, 180 metric tons of mercury were generated in rice plants, 14-fold greater than that exported from oceans via global fisheries. We suggest that future research should consider both the joint ingestion of rice with fish and the food trade in methylmercury exposure assessments, and anthropogenic biovectors such as crops should be considered in the global mercury cycle.
