Chemical Risk Assessment: Purpose, Procedure and Tasks For some people who may be exposed to sulfuric acid (scientists, workers), risk management measures (i.e, wearing goggles and gloves) can be taken to minimize the risk. It is of no or little risk to ordinary people who do not handle them. For example, sulfuric acid is very corrosive. How much of a chemical is present in an environmental medium (e.g., water, soil, air) and how much contact a person or ecological receptor has with the chemical substance ( exposure).ДЄ hazardous chemical substance poses no risk if there is no exposure.The inherent toxicity of the chemical (hazard).To be more specific, the risk of a chemical depends on the following 2 factors:

Risk however, establishes the probability of the adverse effect occurring. Hazard defines the inherent property of a chemical having the potential to cause adverse effects when an organism, system or population is exposed to that agent. When it comes to chemical management, a distinction must be made between hazard and risk.

If you have no chemistry, toxiclogy or eco-toxicology background, please start with following parts first. However, the principles given in this article are consistent with risk assessment methodologies for other sector uses such as pesticides and cosmetics. We will focus on EU REACH regulation and industrial chemicals. In this article, we will give you an introduction to chemical risk assessment.
