The rapid growth of the chemical industry leads to increased production, import, and usage of chemicals. However, introducing any new chemical substance without proper control can threaten human health and the environment.
Specific legal regulations have been introduced to ensure adequate protection and hazard assessment, including Regulation 1907/2006/EC, known as REACH (Registration, Evaluation, Authorisation, and Restriction of Chemicals). REACH mandates the registration of substances through the preparation of appropriate documentation. This documentation includes information about the substance, such as its uses, classification and labeling, safe use instructions, and (eco)toxicological data.
Toxicity data for substances can be obtained through laboratory testing, but REACH recommends using alternative methods whenever possible. Among these methods, computer-based approaches, which QSAR Lab provides, are mentioned. Utilizing these methods allows estimating a wide range of endpoints with significantly lower time and cost investments.
