A
The Clean Air Act addresses air quality.
B
The Clean Water Act regulates pollutant discharges and surface-water quality.
C
The Safe Drinking Water Act sets health-related standards for public water systems.

A neighborhood has extensive paved surfaces, few trees, and uneven access to well-maintained housing and cooling. What should an environmental health assessment do to understand how residents may be affected?

A
Estimate neighborhood temperature only; residents' circumstances are not relevant to assessment.
B
Assume residents face the same heat exposure and vulnerability because they live in the same city.
C
Consider who experiences greater heat exposure or vulnerability, including how housing quality and access to cooling affect impacts.
D
Focus only on whether paved surfaces can generate heat, not on who lives or works nearby.

A neighborhood adds connected sidewalks and accessible transit stops. Which likely health-supporting effect best fits these changes?

A
They are natural environmental features that reduce infectious disease.
B
They are chemical controls that eliminate traffic pollution.
C
They are built-environment features that can make walking and daily travel easier.
D
They are risk-assessment steps used to estimate dose–response.

A chemical can cause harm, but people may have little or no contact with it. Which statement best distinguishes its hazard from the risk it poses to nearby residents?

A
It is risk, because risk means an agent’s ability to cause harm regardless of exposure.
B
It is a hazard, because it describes the agent’s ability to cause harm; risk also depends on exposure conditions.
C
It is exposure assessment, because it combines evidence about effects and exposure.
D
It is risk management, because it describes implementing actions to reduce harm.

After a flood, residents lose housing and local livelihoods are disrupted. Which interpretation best describes a possible environmental-health effect?

A
A flood disrupts housing and local livelihoods, which can affect health indirectly.
B
A flood is a built-environment feature because it affects homes.
C
A flood proves that residents will become ill through a confirmed exposure pathway.
D
A flood is a dose–response assessment because it changes exposure levels.
