What best describes the term 'toxicology'?

• A. The study of pesticide efficacy
• B. The study of how chemicals affect living organisms
• C. The examination of pesticide residues
• D. The evaluation of pest behavior

Answer: (B)

The term 'toxicology' is best described as the study of how chemicals affect living organisms. This field encompasses the analysis of the harmful effects that various substances, including pesticides, can have on health and the environment. Understanding toxicology is crucial for those applying pesticides, as it allows for the assessment of risks associated with chemical exposure and helps in making informed decisions about the safe use of these substances.

Toxicology includes investigating factors such as the dosage, exposure pathways, and the potential for long-term health effects, which are essential for ensuring both human safety and environmental protection. In contrast, other options describe different aspects related to pesticides but do not accurately capture the scope of toxicology itself. The efficacy of pesticides, examination of residues, and evaluation of pest behavior are important areas of study, yet they fall outside the core focus of toxicology.
