Danger assessment as formally practiced by many authorities organizations began as a way To guage the consequences of poisonous substances on human health and fitness, normally the effects of solitary substances, for example pollutants or drugs, from single sources, for instance a chemical plant. Over the nineties, the main target widened to encompass mixtures of substances and also ecological risks. By way of example, ecological risk assessment through the US Environmental Protection Company (1998) begun by asking five queries: Is there a challenge?
