Abstract
Various chemical materials have been contributed to our life remarkably. Like diaxions' case, the influence that might be caused by“ng”or“pg”on order to our body has been recently discussed. When we expose the chemical materials, we have to consider degradation, volatility, accumulation, and concentration in environment.
We can give examples that might be serious porblems in the future followed by these pollutants; sorts of dioxin and its related compounds, tin-organic and other metal organic compounds, chlorine-promine flame detardars, carcinogenic aromatic hydrocarbons, chlorinic hydrocarbons, various pestioides, dioctyl phthalate, toxic products by biological metabolism, and endocrine disruping chemicals. Furthermore, we will be under influences of water pollution itself, flowing through those chemical materials which mentioned earilier and chloride byproducts occured during the process of chlorination in the water supply.
It will be important for us to understand the properties of chemical materials, survey those dangerous sides, and manage them with the safe water and its role in order to coexist with chemical materials.
