Hai Phong coastal water is polluted by nitrite and ammonia (in rainy season) in Bach Dang estuary. Concentrations of nutrients and organic matters at some sites have a tendency of increasing over time. Concentrations of industrial chemicals and POPs are not high, but chloride pesticide concentrations exceed the TCVN standard in rainy season in Bach Dang estuary. Oil and grease concentrations exceeded the standard by 1 to. 3 times in almost all coastal sites. Coliform and Cu and 2n in Bach Dang estuary are the main pollutants of the coastal water. Generally, coastal water of Hai Phong is at risk of pollution (Rq = 0.94). In soil - sediment environment, the concentrations of organic matter, nutrient. oil and grease and heavy metals have been increasing, particularly in Bach Dang estuary and port areas. The concentrations of pesticides in sediments are decreasing or stable over time. Coastal air environment is rather good with most environmental quality parameters being in allowable limits. However, the air quality in urban areas is degraded. indicating pollution risks.
