Describe how the use of fossil fuels contributes to the increase of organic pollutants in the atmosphere.
Describe how the use of synthetic detergents can impact aquatic ecosystems.
Describe the environmental impact of oil spills in marine ecosystems.
Describe the impact of organic pollutants on soil quality.
Describe the process of eutrophication and its relation to organic compounds.
Describe the role of organic compounds in the formation of acid rain.
A chemical plant releases a new organic compound into a river. The compound is found to have a high octanol-water partition coefficient (Kow). What does this indicate about the compound’s environmental behavior, and what are the potential ecological risks?
Consider the following scenario: A pesticide containing an organophosphorus compound is applied to a crop field. After rainfall, the compound is detected in a nearby lake. Explain the possible environmental fate and transformation processes that could affect the compound in the aquatic ecosystem.
