Abstract

Abstract

The effects of content and photobleaching degrees of choromophoric dissolved organic matter were examined based on the photoproduction rates of carbon monoxide for three water samples collected at three different locations in the Jiaozhou Bay in Qingdao. The absorption coefficient of organic compounds and dissolved organic carbon all decreased with increasing time of photobleaching, suggesting that the content of dissolved organic matter significantly decreased through photobleaching. In all eight wave bands, the photoproduction rates of carbon monoxide were significantly correlated with the absorption coefficient at 350 nm and dissolved organic carbon content. Both absorption coefficient at 350 nm and dissolved organic carbon content can represent the contents of chromophoric dissolved organic matter to some extent.
