摘要采用固相微萃取(SPME) 气相色谱法(GC)测定了厦门海域20个站位表层海水中DMS二甲基硫的含量,并对其分布进行分析。结果表明,厦门海域DMS含量在0 65～40 69nmol·L-1,平均浓度为12 83nmol·L-1。其中,西海域的含量最高,东海域次之,同安湾最低。与其它海域海水中DMS浓度比较,厦门海域DMS含量较高,浓度变化范围大,与叶绿素a浓度及表层水温、盐度之间无明显的相关关系。 Dimethylsulfide (DMS) in surface seawater samples collected at 20 stations in the Xiamen sea area were analyzed with SPME-GC method. The results showed that the DMS concentrations varied from 0.65 to 40.69 nmol·L^(-1) with an average of 12.83 nmol·L^(-1). The concentration was the highest in Xiamen Western sea area, while was lower in Eastern sea area and the lowest in Tong'an Bay. Comparation with other sea areas, DMS concentration in Xiamen sea was higher, with the large variation. There were no clear relationships DMS with chlorophyll a, temperature and salty in Xiamen sea.
