Adverse biological reactions can be categorized into several types:
Acute Toxicity: Immediate or short-term effects that occur after a single or short-term exposure. Symptoms can include nausea, vomiting, or respiratory distress. Chronic Toxicity: Long-term effects that develop after prolonged exposure to a toxicant. These effects can be subtle, such as changes in behavior, or severe, like cancer. Allergic Reactions: Immune-mediated responses that occur when the immune system overreacts to a substance. Common symptoms include rashes, itching, and, in severe cases, anaphylaxis. Mutagenicity and Carcinogenicity: Genetic damage that can lead to mutations and cancer. Such effects may not manifest until many years after exposure. Teratogenicity: Effects on the developing embryo or fetus, which can result in birth defects or developmental abnormalities.
