Toxicological studies are resource intensive for several reasons:
1. Complexity of Tests: Evaluating the toxic effects of substances often involves complex and detailed tests. These tests can range from in vitro assays to long-term animal studies. 2. Regulatory Requirements: Regulatory bodies like the FDA and EPA have stringent guidelines that must be followed, which increases the need for specialized resources. 3. Data Management: The vast amount of data generated requires sophisticated data management systems and expert personnel to analyze and interpret results.
