Dissolved, weakly and strongly bound particulates Cu, Pb, Zn, Cd, Co, Ni and Fe have been measured in the surface water sampled from eleven stations in Xiamen Harbor by clean laboratory methods and GFAAS. The average concentrations found in dissolved fractions are Cu: 0.41±0.12; Pb: 0.014±0.008; Zn: 0.084±0.043; Cd: 0.022±0.004; Co: 0.009±0.004; Ni: 0.15±0.02; and Fe: 0.15± 0.02 μg/kg, which make up 62%, 6%, 12%, 85%, 5%, 25% and <1% of the total metals in the surface water respectively. The results are mucn lower than those reported previously in the coastal waters of China. Industrial sources of trace metal contamination are likely responsible for the distribution of trace metals.

从13年前美国高盛公司经济学家吉姆·奥尼尔提出“金砖国家”概念至今,金砖国家不断为世界经济发展注入新活力并成为国际体系的积极建设者。而6年前,金砖国家合作机制诞生的时候,就有舆论认为“BRICS”只是由几个国家名字的缩写拼成的单词,并且认为这5个国家地理位置相距遥远,国际分工水平非常接近,竞争性大于互补性,因此他们并不看好金砖。随着当前金砖五国的经济增速放缓,“金砖失色”的唱衰声再起。  经济日报
