Five experimental water bodies in contrast with Ganggeng Lake were chosen according to water fluoride concentration,and their hydrochemistry characteristic and the fluorine distribution of main economic fish were analyzed.

An investigation of the resources of economic fish was carried out in Meizhou for the first time between the period of September, 2008 and September,2009,using the method of on-the-spot inspections and interviews.

The research showed that the quantity of the FC in the sea watter samples ranged ≤40～≥48 000 cfu/L; in the economic shellfish samples ranged ≤200～240 000cfu/100g.

In this paper the distribution and pollution state of Arsenic remained in the economic shellfishes in the North China coast are described.

The concentrations of the organic chlorine pesticide and PCB in the economic shellfish collected from North of the Changjiang mouth were determined.
