What is the focus of toxicology?

The focus of toxicology centers on the effects of chemicals on living organisms. This field studies how various substances can cause harm to biological systems, examining the mechanisms of toxicity, the dose-response relationships, and the potential health impacts of exposure to different chemicals. Toxicologists investigate the toxic properties of various agents, ranging from industrial chemicals to pharmaceuticals, and assess risks associated with exposure to these substances, making it essential for public health and safety.

In contrast, the other options pertain to different disciplines. Energy consumption relates to the study of how energy is used and managed, not directly related to the effects of chemicals. Waste management procedures deal with the processes involved in handling waste materials, focusing on their disposal, recycling, and environmental impact. Water quality testing involves assessing the chemical, physical, and biological characteristics of water to ensure it is safe for consumption and environmental health, but it does not specifically address the toxicity of chemicals in living organisms.
