“…Elevated arsenic concentrations in rice grain were found from many parts of Bangladesh [14]. Variation in rice grain arsenic concentration in Bangladesh was largely controlled by rice genetics [15]. The accumulation of arsenic in rice plants also varied with different variety of rice [16].…”

A green house field experiment of rice (Oryza sativa L) with arsenic amended irrigation water was conducted at Institute of Environmental Science of Rajshahi University to observe the trend of arsenic (As) accumulation into rice and soil. Sodium arsenate (Na 2 HAsO 4 ) amended irrigation water (0.0, 0.1, 0.5, 1.0, 2.0 and 4.0 mg/l As) was used for cultivating a popular HYV-aman rice variety named BR-11. Arsenic accumulation of rice straw, grain and soil were investigated. A significant (p ≤ 0.01) increasing trend of arsenic accumulation in straw, grain and soil was found with increase of arsenic in irrigation water. The highest level of arsenic in straw, grain and soil was observed in the treatment of 4.0 mg/l As containing irrigation water and lowest level in control treatment. Arsenic in irrigation water showed a strong positive correlations with arsenic accumulation into soil, straw and grain, and the trend of accumulation was found as water > soil > straw > grain.

“…The results of the variety screening trial demonstrated that the element uptake and accumulation capacities varied in different rice varieties, just like the results of Morishita et al (1987), Liu J. G. et al (2005, and Norton et al (2009). Among the 15 rice varieties tested, the highest K, Ca, and Mg contents appeared in the grains of P1; however, its As content exceeded the NFHSC, whereas the Cd content did not.…”

This study was conducted to understand why and how the technologies of variety screening, foliar dressing, and water management can reduce As/Cd accumulation and affect the concentrations of essential elements in different rice plants. In Trial I (variety screening), the grain As and Cd concentrations in Zhongguyou1361 variety (P3) were both lower than their individual National Food Hygiene Standard of China (NFHSC) under insufficient field drying condition. The P3 also had a relatively high yield and high essential element contents among 15 selected rice varieties. In Trial II (foliar dressing), selenite foliar spray showed a better ability than silicate to reduce the grain As content in Guangliangyou1128 variety (P1). However, spraying Se and Si onto the Fengliangyou1 variety (P2) both showed a limited effect on the grain As and Cd contents, suggesting a different effect of Se on grain As content in various rice varieties. The insufficient field drying in Trial II resulted in the grain Cd content being lower but the grain As content being higher than their individual NFHSC in both P1 and Fengliangyou1 (P2) varieties. Se or Si did not affect the yields and the grain contents of most essential elements in P1 and P2. In Trial III (water management), increasing field drying time enhanced the Cd content but reduced the As content in the grains of P1, P2, and P3, and maintained their yields. Similar to the results of Trial II, the changes in soil pH, organic matter concentration and elemental available concentrations could hardly be used to explain why the contents of corresponding essential elements kept approximately constant in the grains of different rice varieties. Foliar dressing with selenite combined with water regulation can simultaneously reduce the As and Cd contents, and maintain the yields and the essential element contents in the grains of rice plants cultivated in As − and Cd − contaminated soil.

“…Rice has significant genotypic differences in HM uptake and accumulation (Liu et al 2005;Cheng et al 2006;Zeng et al 2008;Norton et al 2009). The genotypic differences in HM accumulation make it possible to screen and/or breed cultivars with low metal accumulation in rice grains, which could be the best potential strategy for harvesting safe rice from slightly and moderately HM-contaminated paddy fields.…”

“…In addition, it has been well documented that there are significant genetic variations of HM accumulation in rice grains, including As, Cd, Cu, Zn, etc. (Cheng et al 2006;Zeng et al 2008;Norton et al 2009). Selecting and breeding rice varieties with low HM accumulation in grains could be the most feasible and effective approach to reduce HM levels in the diets produced in HMcontaminated regions.…”

Pig-biogas residue is widely used as organic fertilizer for rice (Oryza sativa L.) in China. To evaluate the risk of heavy metal contamination in paddy soil and rice grains caused by long-term pig-biogas residue fertilization, this study was conducted in paddy fields which had been fertilized continuously with pig-biogas residue for 8 years. We found that pig-biogas residues contained high concentrations of arsenic (As), cadmium (Cd), copper (Cu) and zinc (Zn). As a result, the concentrations of these four metals in paddy soils and rice grains sampled from biogas residue fertilized fields were significantly higher than those from control fields. In addition, in biogas residue fertilized fields, the concentrations of these four metals rapidly increased in the tillage layer compared with those in deep soil layers, and biological availability was significantly higher than in control fields. Moreover, we found that the accumulation of these four metals in paddy soils and rice grains increased in the second year compared with the first year. To reduce heavy metal accumulation in rice grains, we screened for rice genotype among 20 local rice genotypes. We found obvious genotypic differences in grains' accumulation of heavy metals, and identified some rice genotypes which had low accumulation of multiple heavy metals. These low-accumulating genotypes predicate the possibility to reduce heavy metal accumulation in rice grains grown in pig-biogas residue fertilized fields.
