Click on the flashcard to see the answer
What is environmental toxicology?
The study of how pollutants and toxins in the environment impact living organisms.
What are some examples of environmental toxins?
Pesticides, heavy metals, air pollutants, and industrial chemicals.
How do environmental toxins enter the food chain?
Through bioaccumulation and biomagnification.
What are the health effects of environmental toxins?
They can cause various diseases, birth defects, and impairments to the immune and reproductive systems.
What are the main sources of water pollution?
Industrial waste, agricultural runoff, and sewage.
What is the difference between acute and chronic toxicity?
Acute toxicity refers to immediate harmful effects, while chronic toxicity refers to long-term, cumulative effects.
How does climate change impact environmental toxicity?
It can alter the distribution and behavior of toxic substances, leading to increased exposure and risks.
What are the potential solutions to reduce environmental toxicity?
Implementing stricter regulations, promoting sustainable practices, and developing alternative eco-friendly technologies.
What are the effects of air pollution on human health?
Respiratory problems, cardiovascular diseases, and increased risk of cancer.
How does exposure to environmental toxins affect wildlife?
It can lead to population decline, reproductive issues, and disruption of ecosystems.
What is the role of risk assessment in environmental toxicology?
It helps evaluate the potential harm of toxic substances and determine safe exposure limits.
What is the concept of bioavailability in toxicology?
It refers to the degree to which a substance can be absorbed and used by living organisms.
What are the types of chemical hazards in the environment?
Physical hazards, biological hazards, and chemical hazards.
How can individuals contribute to reducing environmental toxicity?
By adopting sustainable lifestyle choices, recycling, and supporting eco-friendly policies.
What are the potential effects of oil spills on marine ecosystems?
Harm to marine life, destruction of habitats, and long-term contamination.
