The urgency of the thesis Vietnam is in the process of industrialization, modernization, many industrial parks and trade villages have sprung up, this has released a large amount of inorganic and organic pollutants. Heavy metals are considered to be very dangerous pollutants due to their high toxicity and high bio-accumulation. Heavy metals like Cadmium, Lead, Mercury, Silver are highly toxic, when accumulated in the human body will cause diseases such as blood pressure, nervous system, brain damage, liver, kidney, circulatory system, severe cases can lead to death. Despite the state regulations on environmental protection, there is no guarantee that heavy metals will be collected and treated thoroughly and safely for the environment. Because of this, environmental .
