7.6-7.8 Reducing Air Pollution and Acid Rain and Noise Pollution

The release of aluminum ions from soil

Acid deposition would most likely result in what?

Caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air

Acid rain is associated with what?

Noise from the highways have disrupted them to find their food

Bats use echolocation to find prey by emitting high-pitched bursts of sound and analyzing the reflection.Scientists studying a population of bats in a forest observed that their population size had declined in the years following the completion of a nearby highway.Based on the information above, describe how noise pollution from the highway has affected the size of the bat population?

Nitrogen oxides, carbon monoxide, and hydrocarbons

Catalytic converters reduce which of the following pairs of pollutants in car exhaust?

Leaves cold ash scrubbed out of the air

Describe an environmental disadvantage of using industrial scrubbers and electrostatic precipitators for pollution abatement.

Designed to receive dusty gas from fugitive or process sources, capture the particulates, and then exhaust clean air

Describe the use of baghouse filters in exhaust systems.

Uses static electricity to remove soot and ash from exhaust fumes before they exit the smokestacks

Describe the use of electrostatic precipitators in exhaust systems.

Use of limestone

Describe the use of fluidized-bed combustion in the boiler furnaces

Use coal that contains less sulfur

How do we reduce SO2 emissions from coal-burning power plants?

Particulates

Is the major pollutant that electrostatic precipitators are designed to remove from power-plant smokestack emissions

Sulfur dioxide and nitrogen oxide

Most often cited as the causative factor for acid deposition?

Burning of sulfur-containing fossil fuels to produce electricity

The primary cause of acid precipitation in the northeastern United States is what?

Reducing the use of fossil fuels

What actions would be the most effective in decreasing acid rain and acid deposition problems?

Nitrogen dioxide and sulfur dioxide

What is an important precursor to acid rain?

Coal burning power plants

What is primarily responsible for acid rain in the northeast United States?

Exposure to loud noise can also cause high blood pressure, heart disease, sleep disturbances, and stress

What is true about noise pollution?

The East because the wind goes West to East

What location in the US would most likely receive acid deposition?

Decreased ability of trees to withstand cold weather

What would be the most likely effect of acid deposition on a northern forest?

An increase in the concentrations of soluble heavy metals in a local pond

What would be the strongest evidence in support of a scientist's contention that a local area was experiencing acid deposition?
