“…Cd, which was a well-known cause of ‘itai-itai’ in Japan in the past, was recently classified as a human carcinogen by the International Agency for Research on Cancer [1]. Cd accumulates in the human body through food, and the main source of dietary Cd intake among Asians is rice [2]–[4]. In rice plants at the grain-filling stage, Cd is absorbed directly by the roots, moves to the panicles, and accumulates in the grain [5], [6].…”

From Laboratory to Field: OsNRAMP5-Knockdown Rice Is a Promising Candidate for Cd Phytoremediation in Paddy Fields

Previously, we reported that OsNRAMP5 functions as a manganese, iron, and cadmium (Cd) transporter. The shoot Cd content in OsNRAMP5 RNAi plants was higher than that in wild-type (WT) plants, whereas the total Cd content (roots plus shoots) was lower. For efficient Cd phytoremediation, we produced OsNRAMP5 RNAi plants using the natural high Cd-accumulating cultivar Anjana Dhan (A5i). Using a positron-emitting tracer imaging system, we assessed the time-course of Cd absorption and accumulation in A5i plants. Enhanced 107Cd translocation from the roots to the shoots was observed in A5i plants. To evaluate the phytoremediation capability of A5i plants, we performed a field experiment in a Cd-contaminated paddy field. The biomass of the A5i plants was unchanged by the suppression of OsNRAMP5 expression; the A5i plants accumulated twice as much Cd in their shoots as WT plants. Thus, A5i plants could be used for rapid Cd extraction and the efficient phytoremediation of Cd from paddy fields, leading to safer food production.

“…In a survey conducted in 1994 [12], Cd-D intake by adult women in Busan was 21.2 lg/day, and Pb-D intake was 20.5 lg/day as GM. When the average body weight of 56.1 kg for mothers in Busan study [17] was applied, Cd-D and Pb-D were 0.28 and 0.37 lg/ kg/day. The present observation for children, 0.58 lg Cd and 0.27 lg Pb/kg/day (Table 1), may be at a similar level with what were reported in these publications [12,17].…”

“…As to be discussed later, potatoes [15,16], meats, fish (including shellfish) and seaweeds [17] in addition to cereals [8,9] were suspected as potential sources of Cd and Pb. Possible association of these food groups with Cd and Pb intake was examined by simple regression analysis (Table 4).…”

“…Women in the exposed group had significantly higher U-Cd (2.20 µg/L) and U-Cd cr (1.43 µg/g) than those in the control group (1.46 µg/L for U-Cd and 1.25 µg/g for U-Cd cr) ( p < 0.01). The U-Cd levels in previous reports of a Korean (control) survey showed 1.23 µg/L for U-Cd and 1.56 µg/g for U-Cd cr [ 26 ]. The geometric mean U-Cd levels in other locations include 1.40 µg/g cr for U-Cd cr in Bangkok [ 27 ], 1.51 µg/g cr for U-Cd cr in Kuala Lumpur [ 28 ], 1.21 µg/g cr for U-Cd cr in Manila [ 29 ], and 1.59 µg/g cr for U-Cd cr in a Taiwan survey [ 30 ].…”

A survey was conducted to evaluate the multi-exposure level and correlation among toxic metal biomarkers (Cd, Pb, and Hg). A total of 592 individuals who participated in the survey were residents near an industrial complex in Gwangyang and Yeosu (exposed group) and of Hadong and Namhae (control group) in southern Korea from May 2007 to November 2010. The Gwangyang and Yeosu area exposed groups had slightly higher blood Pb (2.21 and 1.90 µg/dL), urinary Cd observed values (2.20 and 1.46 µg/L), urinary Cd with a urinary creatinine correction (1.43 and 1.25 µg/g Cr), and urinary Hg observed values (2.26 and 0.98 µg/L) in women participants than those in the Hadong and Namhae area (control group). Blood Pb (3.18 and 2.55 µg/dL), urinary Hg observed values (1.14 and 0.92 µg/L), and urinary Hg with a urinary creatinine correction (1.06 and 0.96 µg/L) for male participants were also slightly higher than those in the Hadong and Namhae area (control group). The correlation among urinary Cd, Hg and Pb concentrations in the blood was significant. We suggest that the exposed group of residents were simultaneously exposed to Pb, Cd, and Hg from contaminated ambient air originating from the iron manufacturing industrial complex.
