Questions and Answers

What are the key differences between physical, chemical, and biological determinations in measuring water and soil pollutants?

Physical determinations focus on the observable characteristics, chemical determinations analyze the chemical composition, and biological determinations assess the presence of living organisms or pathogens.

Explain how noise pollution from industrial sources differs from community noise sources and the implications for measurement.

Industrial noise sources typically produce constant and high-intensity sounds, while community noise sources are variable and often related to activities like traffic or events. This requires different measurement techniques for accurate assessment.

Describe the role of environmental toxicology in assessing the impact of pollutants on human health.

Environmental toxicology studies the effects of chemical pollutants on biological systems, helping to understand the risks they pose to human health and the environment.

Flashcards

Air pollutant

A harmful substance in the air that can affect human health, the environment, and climate. Examples include carbon monoxide, sulfur dioxide, and ozone.

Water pollutant

A substance that contaminates water and makes it harmful for drinking, swimming, or supporting aquatic life.

Soil pollutant

A substance that contaminates the soil and makes it less fertile or unsuitable for plant growth.

Noise pollution

Unwanted or excessive sound that can cause hearing loss, stress, and other health problems.
