Development in coastal areas causing marine pollutionVietNamNet Bridge - Vietnam has 28 out of 63 coastal cities/provinces, where 43.51 million people reside, and the population density is 1.9 times higher than the average density of the country. The waste water from vessels contains high concentrations of mineral oil, cleaning chemicals and heavy metals which seriously threaten the quality of sea water. The waste water from coastal areas, especially from tourism activities, is the main source, contributing one-fourth of total waste water of the country. Waste from miningThe waste water from coal mines cause sedimentation, loss of aquatic resources and deterioration of water quality. It is estimated that the waste water volume from coal mining sites is 25-30 million cubic meters a year with the pH level of 3.1-6.5, while the solid waste volume is up to 150 million cubic meters.
