“…Toxic metal exposure, e.g., lead, via food intake has been a public health concern for decades. The lead content in rice plants has been reported previously in China, Pakistan, Thailand, Bangladesh, and Indonesia [1][2][3][4][5][6]. It was reported that lead was stored up in the order of root > stalk > leaf > grain of the rice plants [2].…”

Lead (Pb) is the most common heavy metal contaminant in plants. It occurs as organic and inorganic salts in plants.Lead is harmful when its amounts in food are higher than the optimum. Rice plants with high levels of lead may trigger the generation of reactive oxygen species and eventually cell death. Our study aimed to assess lead levels in rice plant leaves planted in Sukawening Village, Jatinangor District, West Bandung Regency, West Java. The rice plant leaves were collected each month until four months. The samples were dried and wet-destructed using concentrated sulfuric acid and nitric acid. The qualitative analysis of lead in the samples was carried out using visible spectrophotometry with the addition of xylenol orange. The lead level was measured using a standard addition photometric titration method. Our results indicated that lead was present in the samples since the plant was 1 month old, as proven by the lead-xylenol orange peak at 580 nm. Lead content in the rice plant leaves was as follows, in the 1st-month plants = 0.4118 mg/kg, 2nd-month = 0.5232 mg/kg, 3rd-month = 0.6206 mg/kg, and 4thmonth = 0.5264 mg/kg. We concluded that the lead level in the rice plants is in the range of that required by the Verdict of the Director General of the National Agency of Drug and Food Control No. 03725/B/SK/89 about the Maximum Limit of Heavy Metal Contamination in Food, which is 2.0 mg/kg calculated as the dried samples.

“…However, the paddy fields located near industrial areas and highways are easily contaminated by heavy metals. Previous studies carried out in China, Pakistan, Thailand, Bangladesh, and Indonesia, have reported the heavy metals content in rice [1][2][3][4][5][6]. Lead is harmful when its amounts are higher than the optimum.…”

“…Energy-dispersive X-ray spectroscopy (EDX) may be incorporated in an advanced cutting-edge SEM setup to analyze the atomic composition of the sample surface. The concurrent application of SEM and EDX reveals the size, shape, surface texture, and the factors present in a notably short duration [18].…”

Rice is relatively rich in minerals, including iron, magnesium, and selenium. In the presence of a spark, rice dust suspended in air in a range of concentrations can ignite and explode. The explosion characteristics of brown, black, white, glutinous, and Bario rice were studied in a 20‐L spherical vessel. Brown rice recorded the highest explosion pressure and rate of pressure rise in both dried and undried forms, while Bario rice recorded the lowest. Brown rice was more combustible and tended to develop a fast flame mechanism once ignited owing to its low moisture content and high volatility, which made its explosion more severe compared to that of black, white, glutinous, and Bario rice.

“…Arsenic is of the higher bioaccumulation at both locations and the hazard index value for wild rice seeds from both sites was high. Anwarul Hasan [7] examined the level of heavy metals in soil and rice samples in Savar, Gazipur and Ashulia (Bangladesh). The order of heavy metals in the soil and rice samples was Fe > Zn > Ni > Cr > Pb > Co > Cu > Cd > As and Zn > Cu > Cr > Co > Fe > Cd > Pb > Ni > As, respectively.…”

The concentrations of the heavy metals Pb, Cd, Cr, Hg, As, Cu and Zn in soil and locally produced grain (rice) were determined in paddy soil and rice around an abandoned high-arsenic coal mine area of Xingren county, southwest China. The health risk assessment was used to assess the multimedia and multipathway health risks of HM exposure in the study area. The results showed that the concentrations of As, Pb and Cd in soil were all higher than the corresponding limits for HMs in China. In terms of the accumulation and transfer capacity, Cd was more likely to transfer from the roots to rice, and its strong mobility may pose potential risks to local residents. The non-carcinogenic risks and carcinogenic risks of HM exposure in different media and exposure pathways were higher in children than adults. The total non-carcinogenic risks and carcinogenic risks in adults and children were higher than the standard limit values because of the HM exposure through ingesting rice husk. Among the exposure pathways evaluated, the contribution of diet was the largest, and As was the most important heavy metal in terms of the non-carcinogenic risk and carcinogenic risk factors. The total non-carcinogenic risks and carcinogenic risks caused by As in dietary crop (rice) accounted for 52% of the total in both adults and children. In order to maintain the health of residents in the study area, it is necessary to strictly strengthen the monitoring of heavy metal pollution in the study area and find effective soil improvement methods to reduce the health risks caused by heavy metal exposure.
