Pollution caused by heavy metals (atmosphere, water quality, soil, food, etc.) are called heavy metal contamination. In case of Korea, bullets used in the shooting range, playground's paint finishing materials are to cause metal contamination in real life. Lead content of Korea island that US army were used to the as a firing range, was more than 520 times than the average of Korea, and the content of cadmium exceeded 21 times. The heavy metals were found also, in a playground made in the past. This fact means that the local residents living in the surrounding islands are always exposed to heavy metal poisoning, and children of the leading role in the future also can be exposed to heavy metal poisoning. Because of heavy metal poisoning is very harmful to the human body, I'm try to remove heavy metals of shooting ranges and playgrounds, using Ion-exchange non-woven fabric made by radiation graft polymerization(SS, DEA). |
