“…Thus, the BCF of Cd (0.252) was relatively high in the current study. In another study, the BCF of Cd in rice from farmland near a mine was 0.018 [ 27 ], further suggesting that the BCF of Cd in this study was high. These discrepancies may be explained by the differences in the total heavy metal content and phyto-availability, as well as by physiological differences between crops.…”

“…These discrepancies may be explained by the differences in the total heavy metal content and phyto-availability, as well as by physiological differences between crops. Lim et al, reported high concentrations of Cd and Pb in rice, soybean, sesame, and corn, in this order [ 27 ]. The hazards associated with contaminated agricultural products are proportional to the intake level.…”

Soil contamination is associated with a high potential for health issues. This study aimed to investigate the bioaccumulation of heavy metals and its associated health impact among residents near a mining area. We performed environmental monitoring by analyzing lead (Pb), cadmium (Cd), and arsenic (As) levels in soil and rice samples, as well as biomonitoring by analyzing blood and urine samples from 58 residents living near the mine. Additionally, concentration trends were investigated among 26 participants in a 2013 study. The Cd and As levels in the soil samples and Cd levels in the rice samples exceeded the criteria for concern. The geometric mean blood Cd level (2.12 μg/L) was two times higher than that in the general population aged > 40 years. The blood Cd level showed decreasing trends from the previous measurements of 4.56–2.25 μg/L, but was still higher than that in the general population. The blood and urine Cd levels were higher in those with a low estimated glomerular filtration rate (eGFR) than in those with normal eGFR. In conclusion, heavy metals from mining areas can accumulate in soil and rice, adversely impacting human health. Continuous environmental monitoring and biomonitoring are required to ensure the safety of residents.

There is an increasing concern over arsenic (As) contamination in rice. This study was conducted to develope a prediction model for As uptake by rice based on the physico-chemical properties of soil. Soil and brown rice samples were collected from 46 sites in paddy fields near three different areas of closed mines and industrial complexes. Total As concentration, soil pH, Al oxide, available phosphorus (avail-P), organic matter (OM) content, and clay content in the soil samples were determined. Also, 1.0 N HCl, 1.0 M NH 4 NO 3 , 0.01 M Ca(NO 3 ) 2 , and Mehlich 3 extractable-As in the soils were measured as phytoavailable As concentration in soil. Total As concentration in brown rice samples was also determined. Relationships among As concentrations in brown rice, total As concentrations in soils, and selected soil properties were as follows: As concentration in brown rice was negatively correlated with soil pH value, where as it was positively correlated with Al oxide concentration, avail-P concentration, and OM content in soil. In addition, the concentration of As in brown rice was statistically correlated only with 1.0 N HCl-extractable As in soil. Also, using multiple stepwise regression analysis, a modelling equation was created to predict As concentration in brown rice as affected by selected soil properties including soil As concentration. Prediction of As uptake by rice was delineated by the model [As in brown rice = 0.352 + 0.00109 * HCl extractable As in soil + 0.00002 * Al oxide + 0.0097 * OM + 0.00061 * avail-P -0.0332 * soil pH] (R = 0.714 *** ). The concentrations of As in brown rice estimated by the modelling equation were statistically acceptable because normalized mean error (NME) and normalized root mean square error (NRMSE) values were -0.055 and 0.2229, respectively, when compared with measured As concentration in the plant.

Heavy metal (HM) pollution in agricultural lands and waters, which is rapidly increasing due to social and industrial activities, such as mining and smelting. Moreover, HM contamination causes serious environmental problems and adversely influences on the safety of agricultural production. This study established the concentrations of HM on the arable lands near industrial complexes in Gangwon (GW), Chungnam (CN), Jeonnam (JN), and Gyeongnam (GN) in South Korea. Soil samples were collected and established from 600 sites of agricultural lands nearby 60 industrial complexes in the selected provinces. Eight HMs (Cd, Cu, Pb, Zn, Ni, Cr, As and Zn) were analyzed to compare degrees of the HM pollution using standard analytical methods. The average total concentration of all HMs from samples of the analyzed soils did not exceed the warning criteria as suggested by the Soil Environmental Conservation Law of Korea. The concentration of Cd, Cu, Pb, Zn, Ni, As and Hg were mostly distributed below one half concentration of warning criteria, except for the Cr and Hg. Particularly, 99.2% of Hg concentrations among the assessed samples distributed below one-twentieth values of the warning criteria. Contamination degree (  ) of GW and GN provinces were moderate degree, CN and JN province were low degree contamination. Four provinces were classified as "uncontaminated" by  (Pollution index).
