Development of Rapid Monitoring and Analysis on the Dynamics of Refractory Organic Matter such as Humic Substances in Environmental Water

对琵琶湖水体中溶解有机物(DOM)和荧光团的动态及特征进行了评价。由于类黄腐酸和类蛋白质荧光DOM的分子量可能主要小于3 kDa，除3-30 kDa外，琵琶湖DOM可能与土壤中的黄腐酸和藻类DOM有关。琵琶湖类蛋白荧光团可能归因于藻类DOM中的蛋白质。

The dynamics and characteristics of dissolved organic matter (DOM) and fluorophores in Lake Biwa were evaluated. As the molecular weights of fulvic-like and protein-like fluorescence DOM may be mainly less than 3 kDa and except for 3-30 kDa, respectively, DOM in Lake Biwa might be attributed to both of soil fulvic acid and algal DOM. The protein-like fluorophores in Lake Biwa may be attributed to proteins in algal DOM.
