Scrubbers are air pollution control devices that remove particulate matter and/or gases from industrial exhaust streams. They work by bringing the polluted gas stream into contact with a scrubbing liquid, which absorbs or chemically reacts with the pollutants, effectively cleaning the air before it is released. This method is widely used in various industries to meet air quality standards.

Question 84: Why is recycling important in waste management?

Increases waste.
Conserves resources (Correct answer)
Increases costs.
Pollutes more.

Correct answer: Conserves resources

Recycling is a vital component of waste management because it diverts materials from landfills and incinerators, reducing the need for new raw materials. This process conserves natural resources, such as timber, water, and minerals, and often requires less energy than producing items from virgin materials. Consequently, recycling helps reduce pollution, greenhouse gas emissions, and overall environmental impact.

Question 85: What is a common tool for monitoring water pollution?

Water sampling (Correct answer)
Noise meter.
Thermometer.
Air sampler.

Correct answer: Water sampling

Water sampling is the direct and most common method for monitoring water pollution. It involves collecting representative samples of water from various sources, such as rivers, lakes, or groundwater, for laboratory analysis. This allows for the identification and quantification of pollutants, assessment of water quality, and tracking of pollution sources.

Question 86: What factor MOST affects the validity of assessment & evaluation outcomes in Certified Environmental Inspector?
