Question

Which refers to potentially harmful substances inhaled by organisms/species?​

Answer 1

Answer:

A toxic substance is a substance that can be poisonous or cause health effects. People are generally concerned about chemicals like polychlorinated biphenyls (PCBs) and dioxin which can be found at some hazardous waste sites. Products that we use daily, such as household cleaners, prescription and over-the-counter drugs, gasoline, alcohol, pesticides, fuel oil and cosmetics, can also be toxic. Any chemical can be toxic or harmful under certain conditions.
