| 2003年5月至2004年2月期间，对胶州湾海域进行4个航次的现场调查，根据海洋监测规范对采集水样的pH值、DO、COD、石油、重金属等化学指标进行测定，并对水质现状进行评价。结果表明，2003年5月胶州湾海域DO，COD，石油和Cu，Zn，Pb，Cd，总Hg的质量浓度平均值分别为：6.63，1.51，0.038和2.58，24.86，1.05，0.096，0.043 μg/L；2003年8月DO，COD，石油和Cu，Zn，Pb，Cd，总Hg的质量浓度平均值分别为：5.61，1.27，0.026和3.9，20.5，0.77，0.13，0.041 μg/L；2003年11月DO，COD，石油和Cu，Zn，Pb，Cd，总Hg的质量浓度平均值分别为：7.27，1.86，0.016和4.02，16.55，0.63，0.093，0.06 μg/L；2004年2月DO，COD，石油和Cu，Zn，Pb，Cd，总Hg的平均值分别为：10.1，2.38，0.011和3.45，18.18，0.64,0.16，0.051 μg/L。海泊河口和黄岛轮渡水质已接近重污染；重金属Pb和Zn在部分海区受到轻度污染；有机物污染呈现加重的趋势。

| Abstract: |
| Studying pollution conditions in Jiaozhou Bay had special values in May, August, November, and February, because in these periods climate, rainfall amount and temperature had big changes. The study was conducted to analyse sea water sampling from Jiaozhou Bay for four times during May in 2003 to February in 2004, including testing of power of hydrogen (pH), dissolved oxygen (DO), chemical oxygen demand (COD), oil and heavy meta1s,and assessing water quality. The results showed that average values of DO, COD, oil, Cu, Zn, Pb, Cd, total Hg were 6.63 mg/L, 1.51 mg/L, 0.038 mg/L, 2.58 g/L, 24.86 g/L, 1.05 g/L, 0.096 g/L, 0.043 g/L in May in 2003; 5.61 mg/L, 1.27 mg/L, 0.026 mg/L, 3.9 g/L, 20.5 g/L, 0.77 g/L, 0.13 g/L, 0.041 g/L in August in 2003; 7.27 mg/L, 1.86 mg/L, 0.016 mg/L, 4.02 g/L, 16.55 g/L, 0.63 g/L, 0.093 g/L, 0.06 g/L in November in 2003 and 10.1 mg/L, 2.38 mg/L, 0.011 mg/L, 3.45 g/L, 18.18 g/L, 0.64 g/L, 0.16 g/L, 0.051g/L in February in 2004; the sea waters were polluted seriously in Haibo river mouth and Huangdao ferry. Contents of Pb and Zn exceeded the standards; the pollution of organic compound was serious.
