中文摘要：
海水中的一氧化碳（CO）主要由溶解有色有机物（CDOM）光降解产生,且CO的光致生成量受到环境因素的影响。采集了胶州湾及其河口表层水样,通过实验室模拟实验开展了不同的环境条件（辐射强度、光照时间、温度、pH和盐度）以及水体中CDOM的来源对CO光致生成的影响研究。结果表明胶州湾海水中CO的光致生成速率随辐射强度的增强、水温的升高和水体pH的增大而增大;随着光照时间的延长、水体盐度的增大而逐渐减小;不同来源的CDOM对水体中CO的光致生成速率产生了不同的影响。
英文摘要：
In the ocean,CO is mainly photoproduced by chromopheric dissolved organic matter（CDOM）.It is of vital significance to study the effects of environmental factors,including radiation intensity,irradiation time,water temperature,pH,salinity and photobleaching time of CDOM,on CO photoproduction in seawater.The above mentioned variables on CO photoproduction were examined in surface seawater in the Jiaozhou Bay and its several river mouths in this paper.The results indicate that photoproduction rates of CO increase with radiation intensity,irradiation time,water temperature,pH and decrease with wavelength,salinity,respectively.Photoproduction rates of CO are different due to CDOM of various sources in the photochemical reactions.
