What is a primary source of air pollution?
Industrial emissions
Volcanic eruptions
Photosynthesis
Precipitation
Industrial emissions release pollutants such as sulfur dioxide and nitrogen oxides into the atmosphere. These pollutants are major contributors to air quality degradation.
Which gas is a major greenhouse gas?
Carbon Dioxide
Nitrogen
Oxygen
Argon
Carbon dioxide traps heat in the atmosphere and is a leading contributor to the greenhouse effect. It is emitted in large quantities by fossil fuel combustion.
What is eutrophication?
Nutrient enrichment causing algal blooms
Soil erosion
Ozone layer thinning
Noise pollution
Eutrophication occurs when excess nutrients, especially nitrogen and phosphorus, enter water bodies and promote algal overgrowth. This process can deplete oxygen and harm aquatic life.
Which pollutant is commonly monitored in water quality testing?
Lead
Methane
Chlorofluorocarbons
Particulate matter
Lead is a toxic heavy metal that can contaminate drinking water and pose serious health risks. It is regulated and routinely monitored in water quality testing.
What is an example of point source pollution?
Discharge from a factory pipe
Urban runoff
Agricultural field runoff
Air emissions from vehicles
Point source pollution originates from a single, identifiable location such as a factory outfall pipe. This makes it easier to regulate compared to non-point sources.
Which of the following best describes bioaccumulation?
Increasing concentration of a substance in organisms over time
Spreading of pollutants in the air
Natural attenuation of contaminants
Removal of toxins by filtration
Bioaccumulation refers to the build-up of chemicals in an organism's tissues over time. It occurs when an organism absorbs a substance faster than it can excrete it.
Which regulation sets the maximum contaminant levels for drinking water in the United States?
Safe Drinking Water Act
Clean Air Act
Resource Conservation and Recovery Act
Endangered Species Act
The Safe Drinking Water Act authorizes the EPA to establish maximum contaminant levels in public water systems. It aims to protect public health by regulating harmful substances.
How does particulate matter (PM2.5) primarily affect human health?
Penetrates deep into lungs causing respiratory issues
Causes skin irritation
Contributes to ozone depletion
Increases noise levels
PM2.5 particles are small enough to penetrate deep into the respiratory tract and enter the bloodstream. This can exacerbate asthma and other lung diseases.
What is the purpose of an Air Quality Index (AQI)?
Communicate daily air pollution levels to the public
Measure soil acidity
Regulate water pH levels
Monitor noise pollution levels
The AQI translates complex air monitoring data into a simple scale to inform the public about health risks. It helps people decide when to reduce outdoor activities.
Which technique is commonly used for controlling industrial SO₂ emissions?
Flue-gas desulfurization
Chlorination
Bioremediation
Sedimentation
Flue-gas desulfurization removes sulfur dioxide from exhaust flue gases of power plants. It uses chemical reactions to convert SO₂ into gypsum or other useful materials.
In soil contamination cleanup, what is phytoremediation?
Use of plants to absorb or degrade pollutants
Chemical oxidation by ozone
Soil washing with solvents
Adding nutrients to soil
Phytoremediation uses plants to remove, stabilize, or degrade contaminants in soil. It is a cost-effective and environmentally friendly remediation method.
What does Biological Oxygen Demand (BOD) measure in water?
Amount of oxygen required to decompose organic matter
Total dissolved solids concentration
Heavy metal concentration
Water turbidity level
BOD indicates the amount of dissolved oxygen needed by microorganisms to break down organic material. High BOD levels suggest heavy organic pollution.
Which of the following is a non-point source of pollution?
Runoff from agricultural fields
Effluent discharge from a sewage treatment plant
Accidental oil spill from a pipeline
A single factory chimney emission
Non-point source pollution comes from diffuse sources like agricultural runoff carrying fertilizers and pesticides. It is harder to regulate than point sources.
What is the main health risk associated with nitrate contamination in groundwater?
Methemoglobinemia in infants
Lung cancer
Skin dermatitis
Hearing loss
High nitrate levels in drinking water can cause methemoglobinemia or 'blue baby syndrome' in infants. This condition reduces the blood's capacity to carry oxygen.
Which term describes the ability of an ecosystem to recover from pollution stress?
Resilience
Sensitivity
Fragility
Latency
Resilience refers to an ecosystem's capacity to absorb disturbances and regenerate. It is a key concept in assessing environmental recovery.
A river's nitrate concentration increases from 2 mg/L upstream to 8 mg/L downstream after passing agricultural land. What is the percent increase?
300%
400%
200%
150%
The increase from 2 mg/L to 8 mg/L is (8−2)/2×100, which equals 300%. This calculation represents the relative change in concentration.
Which pollutant is regulated by the Montreal Protocol?
Chlorofluorocarbons
PM10 particles
Lead
Sulfur dioxide
The Montreal Protocol targets ozone-depleting substances such as chlorofluorocarbons (CFCs). It has led to global reductions in CFC production and use.
In a closed-chamber test, a VOC concentration drops from 100 ppm to 40 ppm over 5 hours following first-order kinetics. What is the approximate half-life?
3.8 hours
5 hours
1.5 hours
6.2 hours
Using Ct=C0e−kt, 40=100e−5k gives k≈0.1833 h−1. The half-life is ln2/k≈0.693/0.1833≈3.8 hours.
Which soil property most influences the mobility of heavy metals in contaminated soil?
pH
Texture (clay content)
Temperature
Color
Soil pH affects metal solubility and adsorption to soil particles. Lower pH generally increases metal mobility and bioavailability.
Under the Clean Air Act, the primary National Ambient Air Quality Standard (NAAQS) for ozone is designed to protect what?
Public health against respiratory effects
Water quality
Soil microbial communities
Global climate change
The primary NAAQS for ozone focuses on preventing adverse respiratory health impacts. It sets concentration limits to protect sensitive populations.
