What do we call the hazardous substances that are found in various chemicals, both natural and man-made?

The correct answer identifies hazardous chemicals that pose risks to health. This designation encompasses a wide range of substances, whether they are natural or synthetic, that can cause adverse effects on human health or the environment. These chemicals can include toxic materials, carcinogens, corrosives, and other compounds that can lead to serious health issues when exposure occurs.

In the context of safety regulations and environmental health, recognizing and categorizing these substances as hazardous is crucial for effective management and control. This classification helps in implementing necessary safety measures, conducting risk assessments, and ensuring compliance with safety regulations to protect individuals and communities from potential dangers associated with these chemicals.

The other options, while related, do not accurately capture the broader scope of hazardous substances. For instance, some may refer specifically to ethical concerns or may not necessarily indicate the direct health risks posed by the chemicals, thereby not encompassing the full range of hazardous substances recognized in health and safety discussions.
