What are the harmful effects of a mixture?
These effects include enhanced acute and chronic responses, low-level concentration response, and unexpected target organ attack. Octanol:water partition coefficients are predictive of relative lipophilicity and hydrophilicity.
How can mixtures be harmful to the environment?
Microbial communities that can degrade or can degrade or can develop tolerance to, or are inhibited by chemical mixtures greatly contribute to resilience and resistance in soil environments.
What is mixture effect?

How are chemicals harmful to people and the environment?
Some wastes contain chemicals that are hazardous to people and the environment. Once these hazardous chemicals are present in the environment, people can become exposed to them. Exposure occurs when people have contact with a chemical, either directly or through another substance contaminated with a chemical.
