The endocrine hormones serve as signals from one body system to another regarding an enormous array of conditions, and resulting in variety of changes
GreenScreen for Safer Chemicals GreenScreen for Safer Chemicals The GreenScreen for Safer Chemicals is a transparent, open standard for assessing chemical hazard that supports alternatives assessment for toxics use reduction through identifying chemicals of concern and safer alternatives. It is used by researchers, product formulators and certifiers in a variety of industries, including building products, textiles, apparel, and consumer products. The GreenScreen prioritizes the avoidance of substances with a high hazard as a carcinogen, mutagen, reproductive toxicant or developmental toxicant or endocrine disruptor or that are a persistent, bioaccumulative and toxic substance (PBT).
