Minnesota Air and Health Initiative

MPCA/MDH collaboration to understand and address role of air quality in our health

Common responsibility to protect and improve public health

MPCA and MDH roles

MPCA: generates air quality monitoring and modeling data, estimates risks to inform

actions

MDH: conducts disease surveillance to inform disease prevention actions, including

data on social, behavioral and environmental risks

Background

Original Life and Breath study

7-county metro area, 2015 report of air pollution impacts on health in 2008
In Metro area- PM2.5 and ozone contributed to approximately:
1,000 - 2,000 premature deaths
400 hospitalizations
600 emergency room visits
Some sub-populations – elderly, young children, areas with higher proportions of minority

populations and residents living in poverty – are particularly vulnerable to air pollution

Air and health

How can health impacts of air pollution be counted?

Epidemiological studies measure the

relationships between pollutant concentrations and health.

From these relationships, we can

estimate the fraction and count of adverse health impacts that may be attributed to air pollution.

SLIDE 7

Statewide “Life and Breath II”

Goals for “Life and Breath II”

What are the impacts of fine particulate

matter and ozone state-wide?

Are the impacts distributed equally

across the state?

What benefits can be achieved by further

reducing air pollution across the state?

Aggregate findings

We estimate:

Between 5-10% of all Minnesotans died prematurely, in part, due to fine

particles in the air or ground-level ozone.

ØThis translates to nearly 2,000 to more than 4,000 premature deaths annually

Between 1-5% of all residents who went to the hospital or emergency room

did so partly because of fine particle matter in the air or ground-level ozone exposures.

ØThis translates to approximately 500 hospitalizations, and 800 emergency room visits annually.

Key EJ/equity mortality findings

Early deaths:

Populations most impacted across the state include counties where >25% of the

population is living in poverty.

Rural areas have higher burdens of air pollution-attributable impacts (age

distribution and other social and demographic structures have larger roles than air quality differences).

Areas with higher uninsured populations have higher burdens of air pollution-

attributable impacts.

Young and elderly are vulnerable populations.

Key messages

Air quality in Minnesota currently meets federal standards, but even low and

moderate levels of air pollution can contribute to serious illnesses and early death.

Everyone can be affected by breathing polluted air, but some groups and areas of the

state are more vulnerable than others.

Because many things in addition to air impact our health – like age, health care and

socioeconomic status – areas with higher underlying death and disease rates have higher health impacts from air pollution.

Air pollution impacting health is not just a big city or metro area issue.
To reduce the impacts of breathing polluted air, multi-pronged policy approaches are

needed that address underlying causes of health disparities and improve air quality.

What is being done?

6/13/19 27

SLIDE 28

MDH action

MDH strives to:

Work toward health systems and environmental regulations that promote a

healthy environment

Expand linkages between communities and clinical care and prevention services
Advance health-based guidance for regulators on key air pollutants
Track connections between environmental exposures, inequities, and health
utcomes
Identify vulnerable populations and determine sub-groups for future risks

6/13/19 28

SLIDE 29

MPCA action

MPCA is working with partners to:

Reduce pollution in population centers focusing on areas of concern for

environmental justice

Reduce vehicle emissions
Improve understanding of air quality at the community scale
Increase awareness about air quality forecasts, alerts, and tools for communities

and health care providers

6/13/19 29

SLIDE 30

Community action

What can communities do to help decrease air pollution and vulnerability?

Vehicle exhaust is the major source of air pollution in MN, whenever possible drive

less and/or car pool

Don’t burn garbage and keep campfires small (only on non AQI days)
Check for AQI days
Switch to electric when possible (e.g. lawn equipment)
Plant trees when possible!
