Compared to the highly polymerized compound, therefore, the structure of the environmental hormone is very simple. A constituent unit of those is also water-soluble. However, an environmental hormone is insoluble in water, and it is soluble in oil. These are steroids. Organisms are decomposed after their deaths.
Enzymatic actions decompose materials.
On the other hand, environmental hormones are not easily decomposed in living bodies. Now, a way to change this characteristic of plastic has recently been investigated. A very small quantity can affect It is the significant character of an environmental hormone that a small amount of the contaminant affect organisms. At first, we have to make a list of environmental hormones. Next, it is necessary to settle a range of the tolerable amount of these contaminants.
