Received: 31 March 2011; in revised form: 9 May 2011 / Accepted: 16 May 2011 / Published: 19 May 2011 Abstract: The dissolved organic matter (DOM) is one of the important factors for controlling water quality. The behavior and constitutions of DOM is related to the risk of human health because it is able to directly or indirectly affect the behavior, speciation and toxicity o
