Distribution features of oil and preventive countermeasures in Meizhou Bay, China

The content and distributive feature of oil in Meizhou Bay, China during summer were analysed on the basis of water quality survey. The result showed that oil concentration ranges between 5-51μg/dm3 with an average of 19.8 μg/dm3 . The mixed coefficient is lower. The difference of oil distribution between high tide and low tide is related to the distribution of land pollution and is mainly decided by water dynamics. Average turn- over rate and enrichment coefficient can provide fundamental information to estimate oil concentration in sea water.
