摘要

通过向土壤中添加水稻秸秆生物质碳（RSB）、玉米秸秆生物质碳（MSB）和鸡粪生物炭（CMB）来减少微囊藻毒素-LR（MC-LR）在生菜中的富集.结果表明，RSB、MSB和CMB在添加量为2%时，生菜叶片中MC-LR含量较空白分别降低了58.0%、49.5%和70.4%，使得每日估计摄入量降低到WHO的每日允许摄入量限值以下.CMB显著降低了土壤中MC-LR的总含量，而其他处理则无显著影响.3种生物质碳均显著降低了有效态MC-LR含量，且生菜根系和叶片中MC-LR的含量与土壤MC-LR有效态含量均呈显著正相关关系.所有添加生物质碳处理均对生菜生长无负面影响.

Abstract

Three kinds of biochars, rice straw biochar (RSB), maize straw biochar (MSB), and chicken manure biochar (CMB), were added to the soil in order to reduce microcystin-LR (MC-LR) bioaccumulation in lettuce. Results showed that addition of 2% RSB, MSB and CMB decreased the content of MC-LR in the lettuce leaves by 58.0%, 49.5% and 52.3%, respectively, and the estimated daily intake values were much lower than the tolerable daily intake limit proposed by the WHO. All the biochars have no significant impact on soil total MC-LR concentration except CMB, which significantly decreased soil total MC-LR concentration. Bioavailable MC-LR concentrations were significantly decreased by all three biochars. The correlation analysis showed that there was a positive correlation between the bioavailable MC-LR concentrations in the soil and the MC-LR content in lettuce roots, as well as the leaves. Application of biochars had no negative impact on lettuce growth.
