Abstract | 稻米对甲基汞的累积危害居民身体健康。本文通过施用厌氧腐熟有机肥的盆栽试验,探讨有机肥施用对水稻中汞-甲基汞累积的影响。结果表明,有机肥施用水稻土中甲基汞含量显著增加,对照(10.43 g/kg) |
Other Abstract | Accumulation of methylmercury in rice is harmful to the health of consumers. A pot experiment was conducted to study the effects of organic fertilizer application on the accumulation of mercury and methylmercury in rice in mercury-methylmercury contaminated soil. The treatments included CK, no organic fertilizer + long term flooding;AWD, no organic fertilizer + dry/wet alternation;BOM1, rotten soybean meal (1%, w/w) + long term flooding;BOM2, rotten soybean meal (2%, w/w) + long term flooding;FOM1, rotten fish meal (1%, w/w) + long term flooding;FOM2, rotten fish meal (2%, w/w) + long term flooding. The results showed that organic fertilizer significantly increased CH3Hg+ content in paddy soil: CK (10.43 g/kg) < BOM1 (16.80 g/kg) < FOM1 (24.10 g/kg) < BOM2 (33.53 g/kg) < FOM2 (38.46 g/kg). After the application of organic fertilizers, total Hg accumulation in various rice organs were significantly different, the highest in root (2 812.83 g/kg), followed by brown rice (336.78 g/kg) and stem and leaf (300.44 g/kg), the abilities to accumulate CH3Hg+ by different rice organs were different: grain (180.06 g/kg) > root (59.71 g/kg) > stem and leaf (38.97 g/kg). Organic fertilizers increased the content of CH3Hg+ in rice grains compared with the CK treatment: BOM1 (16.1%) < FOM1 (19.3%) < BOM2 (41.5%) < FOM2(57.9%). Significant positive correlation was found between CH3Hg+ concentration in rice grains and CH3Hg+ content in paddy soil. This study proved organic manure can increase the accumulation of mercury and methylmercury in rice in mercury contaminated soil, and it provided scientific basis and theoretical guidance for rational fertilization. |
