摘要
20 0 0年 10月对小窑湾底质沉积物进行了 10个项目的海上调查 ,结果表明 :小窑湾底质重金属含量均为国家一类标准 ,符合渔业生产条件 ;硫化物、有机质含量虽然为国家一类标准 ,但已趋于上限 ,说明底质已被污染 ;油类已达国家二类标准 ,超出了渔业生产的许可范围 ;底质沉积物中每天向海水中释放的氮为 12 936mg/(m2 ·d) ,释放的磷为 0 4 95mg/ (m2 ·d)。
Ten monitoring items about the sediments in Xiaoyao Bay were investigated in October 2000.The results showed that the heavy mental contents in sediments were among the national first criterion and suitable for fishery production;sulfides and organic matters were also among the national first crierion but near the up limit which meant the bottoms had been polluted;the oil contents in sediment were among the national second criterion and beyond the permitting limits of fishery production.The contents of nitrogen released from sediments to seawater were 12.936mg/m 2.d,which of phosphate were 0.495 mg/m 2.d.
