摘要

于2017年7—8月对中国长江口及其邻近海域表层及重要断面不同深度海水中二甲基硫(DMS)、二甲基巯基丙酸内盐(DMSP)和二甲亚砜(DMSO)的浓度进行了测定,探讨了长江冲淡水对其分布的影响,并估算了DMS的海-气通量.结果表明,表层海水中DMS、溶解态DMSP(DMSPd)、颗粒态DMSP(DMSPp)、溶解态DMSO(DMSOd)和颗粒态DMSO(DMSOp)的浓度平均值分别为(5.69±5.20)、(6.67±4.90)、(19.46±9.26)、(24.67±20.52)和(24.97±20.85) nmol·L~(-1).DMS和DMSP大体呈现出一致的分布规律,高值区出现在冲淡水与海水的混合区域,在长江口口门附近出现低值.相关性分析结果表明,DMSPp与DMSOp存在相关性,这可能与二者有相似的来源和细胞功能有关.DMSPd、DMSOd均与DMS存在相关性,这是因为DMSPd降解是表层海水中DMS的主要来源,而DMS的光氧化和微生物氧化可能是夏季表层海水中DMSOd的重要来源途径.沉积物间隙水中DMSPd浓度高于底层海水,表明沉积物释放也是底层DMSPd的一个来源.此外,夏季长江口及邻近海域DMS的海-气通量介于0.29～34.63μmol·m~(-2)·d~(-1)之间,平均值为(8.37±11.79)μmol·m~(-2)·d~(-1).
        The spatial distributions of dimethysulfide(DMS), dimethylsulfoniopropionate(DMSP) and dimethylsulfoxide(DMSO) as well as their influencing factors were investigated in the Yangtze River Estuary and its adjacent area during July-August 2017, to study the impact of Yangtze River diluting water and to estimate the sea-to-air flux of DMS. The mean concentrations of DMS, dissolved DMSP(DMSPd), particulate DMSP(DMSPp), dissolved DMSO(DMSOd) and particulate DMSO(DMSOp) in the surface seawater were(5.69±5.20),(6.67±4.90),(19.46±9.26),(24.67±20.52) and(24.97±20.85) nmol·L~(-1), respectively. Overall, DMS and DMSP exhibited the same distribution pattern, with the highest values occurring in the mixed areas of diluting water and seawater and the lowest values appearing at the mouth of the Yangtze River Estuary. A significant correlation was observed between DMSPp and DMSOp, due to their similar source and cellular function. In addition, the relationships between DMSPd, DMSOd and DMS were found, respectively, because of the degradation of DMSPd was the main source of DMS and the photooxidation and microbial oxidation of DMS might be an important source of DMSOd in the surface seawater. The concentration of DMSPd in the sediment porewaters was higher than that in the bottom seawater, indicating that the release of DMSPd in sediment might be a source of DMSPd in the underlying seawater. Furthermore, the sea-to-air flux of DMS ranged from 0.29 to 34.63 μmol·m~(-2)·d~(-1) in the study area, with an average of(8.37±11.79) μmol·m~(-2)·d~(-1).
