Ảnh hưởng của các hoạt động kinh tế đối với chất lượng môi trường phần Tây nam vịnh Văn PhongAbstract
At present, the water environment of the southwest part of Van Phong bay is relatively good. Pollution of organic matters and heavy metals (Fe, Zn) is fairly. However, the high content of heavy metals was recorded in just settled thin layer of sediment near the sea port of Hyundai-Vinashin Shipyard (April 2000). It is reasonable to say that the activity of the shipyard is the unique industrial factor that can impact upon the environmental quality of studied waters and its adjacent land. Preliminary impacts of wastes from the shipyard were noted (high contents of heavy metal concentration in water column, sediments, and high bioavailableness). Among the wastes from the shipyard NIX grain (used in cleaning the boat before painting) is the main pollutant source. The negative impacs of the NIX grain become more seriously when the shipyard extends its activity. The negative impacts of NIX can be eliminated by the recovery and treatment of this solid waste. The best solution may be the replacement of NIX by quartz sand. If this solution is impossible, reuse of solid waste is very necessary.Journal
