【摘要】 本文首次报道了福建南日岛海域溶解态Cu、PB、Cd的含量，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0．84、0．230、0．023μg／dm3；1990年10月分别为0. 78、0．290、0. 033μg／dm3。其5月溶解态Cu与无机氮N（NO3-＋NO2-＋NH4+）线性回归的相关式为Cu（μg／dm3）＝-0. 789＋0．328N（μmol／dm3），相关系数r＝0．853，原子比△Cu：△N＝5．17×10－3：1。更多还原

【Abstract】 The prsent paper first reports contents of dissolved Cu,Pb and Cd in Nanri Island wa ters,Fujian Province and the dissolved trace metal-nutrient relationships. The mean contents of dissolved Cu,Pb and Cd were 0. 84,0. 230 and 0. 023μg/dm3 in May and 0. 78,0. 290 and 0.033 μg/dm3 in Oct. 1990. The resulting equation of linear regression between dissolved Cu and inorganic nitrogen N (NO3-+NO2-+NH4+) in May was Cu (μg/dm3 ) =-0. 789+0. 328 N (μmol/dm3),r=0. 853,△Cu: △N molar ratio was 5. 17 × 10-3: 1.更多还原
