| 摘要: |
| 根据2006~2007年钦州近江牡蛎天然增养殖区、合浦廉州湾贝类(文蛤)养殖区的调查监测数据,综合分析和评价广西主要海水贝类养殖区域环境质量状况。在监测和评价的环境质量因子中,广西主要海水贝类养殖区的绝大多数监测指标均符合渔业水质标准和海水水质标准(Ⅱ类)的要求,环境质量状况总体良好,适合发展贝类养殖生产。广西主要海水贝类养殖区的主要污染物为无机氮、活性磷酸盐及沉积物中重金属铜、锌、砷等,这些监测指标在贝类养殖区局部出现超标情况,其中钦州近江牡蛎天然增养殖区2007年无机氮平均含量(0.40mg/L)超标0.34倍,铜含量最高值(39mg/kg)超标0.11倍,锌含量最高值(474mg/kg)超标2.16倍;合浦廉州湾贝类养殖区的东江口监测点2007年的无机氮(0.380mg/L)和活性磷酸盐(0.0362mg/L)略为超标,但均比2006年明显降低,2007年党江深水区监测点砷含量(39.11mg/kg)超标0.96倍。超标原因是养殖区外源污染或环境本底超标,而非贝类养殖自身污染所致。 |

| Abstract: |
| According to the investigation and monitoring results of the Crassostrea rivularis natural culture areas in Qinzhou and shellfish (clams) culture areas in Lianzhou Bay of Hepu in 2006~2007,a comprehensive analysis and evaluation of major seawater shellfish aquaculture areas environmental quality in Guangxi were obtained.In monitoring and evaluation of environmental quality factors,the majority of indicators for monitoring seawater quality standards in the major seawater shellfish culture zones met the fisheries and seawater quality standards (Ⅱ type).The general quality of environment is good and suitable for the development of shellfish aquaculture.The major pollutants in main seawater shellfish culture areas are inorganic nitrogen, reactive phosphate and heavy metals in sediment such as copper,zinc,arsenic,etc.These monitoring indicators in part of shellfish culture zones was over standards.In Crassostrea rivularis natural culture areas in Qinzhou in 2007 the average content of inorganic nitrogen was 0.40mg/L that is 0.34 times of that in standards.The highest value of Cu was 0.11 times of that in standards (39mg/kg) and the highest value of zinc over 2.16 times of that in standards(474mg/kg) Data from the East Jiang monitoring points of Hepu Lianzhou Bay shellfish aquaculture in 2007 showed that the inorganic nitrogen was 0.380 mg/L and reactive phosphate was 0.0362 mg/L.The inorganic nitrogen and reactive phosphate were slightly over that in the standards but significantly lower than in 2006.The monitoring points of Dang river in 2007 reported that arsenic concentration is 39.11 mg/kg that is 0.96 times of that in the standards.However,the arsenic concentration over standard is due to pollution either from outside of culture area or environment background,rather than shellfish aquaculture. |
