摘要
首次报道了福建省福清市江阴岛海域溶解态Cu、Pb、Cd的含量,并探讨了它们与营养盐的关系.1990年5月溶解态Cu、Pb、Cd的平均含量分别为0.82、0.380、0.022μg/dm^3.;10月的平均含量分别为0.76、0.382、0.032μg/dm^3.其5月溶解态Cu与无机氮N(NO_3^-+NO_2^-+NH_4^-)、硅酸盐(SiO_3^(2-))间的线性回归相关式分别为Cu(μg/dm^3)=0.438+0.0377N(μg/dm^3)、Cu(μg/dm^3)=0.592+0.016Si(μg/dm^3).5月Cu分布与无机氮、硅酸盐再生循环关系密切.
The contents of dissolved Cu, Pb and Cd in the waters off the Jiang Yin Island of Fujian Province are presented and their relationship with the dissolved trace metal-nutrient are probed. The mean concentration value of dissolved Cu, Pb and Cd in May 1990 were 0. 820, 0. 380 and 0. 022ug/dm3 respectively,and that in October 1990 were 0. 76,0. 382 and 0. 032ug/ dm3 respectively. The equation for linear regression between dissolved Cu and inorganic nitrogen (NO3-+NO2-+NH4+) in May is Cu (ug/dm3) =0.438 + 0. 0377N(umol/dm3) ;that between dissolved Cu and silicate (SiO32-) is Cu (ug/dm3) = 0. 592 + 0.0155 Si (umol/dm3). Thers is good correlation between the distribution of Cu and the regeneration cycle of N and SiO32- in May.
