【摘要】 在长兴岛北岸,采集平整冰、堆积冰和搁浅冰。作了26项水质分析,采用三种行业标准评价,结果表明全盐量、氯化物和硫酸盐指标不合格,平整冰全盐量按非盐碱地区标准评价超标7.7倍,按盐碱地区标准评价超标3.8倍。氯化物超标16.6倍,硫酸盐超标2.3倍。堆积冰全盐量按非盐碱地区标准评价超标6.7倍,按盐碱地区标准评价超标2.3倍。氯化物超标15.6倍,硫酸盐超标1.5倍。搁浅冰全盐量按非盐碱地区标准评价超标3.7倍,按盐碱地区标准评价超标1.8倍。氯化物超标10.4倍,硫酸盐超标1.4倍。其余23项合格。更多还原

【Abstract】 Analysis of 26 items of water quality in onepiece, cumulate and neaped ice collected in the northern of Changxing Island and evaluate by three kinds of trade standards were done. The results shown that the total salt, the chloride and the sulfate are not up to grade. The total salt in onepiece ice is 6.7 times higher than the standard of the nonsalt area and 2.8 times higher than the salt area. The chloride in onepiece ice is 15.6 times higher than the standard. The sulfate in onepiece ice is 1.3 times higher than the standard. The total salt in cumulate ice is 5.7 times higher than the standard of the nonsalt area and 1.3 times higher than the salt area. The chloride of cumulate ice is 14.6 times higher than the standard. The sulfate in cumulate ice is 0.5 times higher than the standard. The total salt in neaped ice is 2.7 times higher than the standard of the nonsalt area and 0.8 times higher than the salt area. The chloride in neaped ice is 9.4 times higher than the standard.The sulfate in neaped ice is 0.4 times higher than the salt area. The other items are up to grade.更多还原
