Despite advances, toxicological research faces several challenges. One significant issue is the ethical concerns associated with animal testing, which has led to a push for alternative methods. Additionally, the sheer number of chemicals in use today complicates the task of assessing their potential risks. Another challenge is the need to understand chronic exposure effects, as most research focuses on acute toxicity. There is also a growing need to study the impact of chemical mixtures, as real-world exposures often involve multiple substances.
