7.6-7.8

Acid deposition would most likely result in what?

Acid deposition would most likely result in the release of aluminum ions from soil.

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

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

Describe the use of baghouse filters in exhaust systems.

Baghouses utilize fabric filter bags or pleated filters arranged in rows and mounted vertically in a sheet metal housing. They are designed to receive dusty gas from fugitive or process sources, capture the particulates, and then exhaust clean air.

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

Burn less coal or use baghouse filters, FBCs, etc

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

Catalytic converters are used in exhaust systems to provide a site for the oxidation and reduction of toxic by-products (like nitrogen oxides, carbon monoxide, and hydrocarbons) of fuel into less hazardous substances such as carbon dioxide, water vapor, and nitrogen gas.

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

Coal ash contains toxic levels of several different pollutants

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

Decreased abilities for the trees to survive (mainly in the cold)

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

Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials

What is true about noise pollution?

Impacts millions, can cause hearing loss

What is an important precursor to acid rain?

Nitrogen dioxide

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

The coal power plants that are west of them, in the (eastern) midwest. And the winds that take them to those cities

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

The coal power plants west of it

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?

The highway noise washes out the sounds of the echolocation and the bats cannot find food, and are therefore dying.

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

a town downwind from a coal-fired power plant.

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

particulates

Acid rain is associated with what?

sulfur

Most often cited as the causative factor for acid deposition?

sulfuric acid

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

use a FBC

Describe the use of electrostatic precipitators in exhaust systems.

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