Toxicity refers to the degree to which a substance can cause harm to living organisms. It depends on the type of toxicant, its concentration, duration of exposure and the sensitivity of the organism. In this video, we explain the concept of toxicity in biology and environmental science, different types of toxicity (acute and chronic), dose–response relationship, LD50, bioaccumulation, biomagnification and toxic effects on various organs and systems. We also discuss examples of common toxic substances in the environment and methods used to assess and reduce toxicity. This topic is important for students of toxicology, environmental science and ecology, and is also useful for competitive exam preparation. Watch till the end to clearly understand the impact of toxic substances on living organisms and ecosystems.
