IntroductionThe environment
plays a big role on human health.
Public health agencies decide policy based on the environmental factors at play in their area of jurisdiction.

IntroductionEnvironmental factors
can influence the macroenvironment that is a person’s city, province, country or continent OR the microenvironment that is a person’s home, vehicle and workplace/school.

1) Climate ChangeAs the world is
becoming warmer due to the runaway greenhouse effect, the tropical regions of the world are expanding into what was once known as a temperate climate zone (James Cook University 2009 Study).
![Page 6: Introduction The environment plays a big role on human health. Public health agencies decide policy based on the environmental factors at play in their.](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649dc95503460f94ac048a/html5/thumbnails/6.jpg)
1) Climate ChangeWith this push outward
from the equator comes with it tropical pathogens and the diseases they bring.
The majority of tropical diseases are passed through insect vectors which need a humid climate, high temperatures and lots of precipitation (for their larvae).
Once previously temperate areas now meet these criteria (i.e. Southern USA, Mediterranean Coast)

2) Air PollutionThe human health
effects of air pollution are far reaching, but mainly affect the respiratory and circulatory systems.
The negative health effects depend on the time/frequency of exposure, the type of pollutant and the person’s overall general health.
![Page 8: Introduction The environment plays a big role on human health. Public health agencies decide policy based on the environmental factors at play in their.](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649dc95503460f94ac048a/html5/thumbnails/8.jpg)
2) Air PollutionThe respiratory system
is particularly affected by pollutants because it is made up of mostly thin-walled tissue.
Many pollutants can break down these tissues and over time, damage them permanently.
Pollutant effects can be amplified by the respiratory system and spread to other areas of the body.
![Page 9: Introduction The environment plays a big role on human health. Public health agencies decide policy based on the environmental factors at play in their.](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649dc95503460f94ac048a/html5/thumbnails/9.jpg)
2) Air PollutionThe inhalation of
pollutants eventually puts them into the blood stream and brings them eventually to the heart.
Many pollutants can break down heart muscle, lead to irregular heartbeats or worse.

2) Air PollutionThis weakening of
two of the main systems in the body will generally lower the body’s immune system and leave them open to attack by pathogens.

Hospitalization and Mortality

3) Water PollutionNo matter where we live, our
drinking water originates in a watershed, a land area that drains to a single body of water that may be surface water or groundwater.
These watersheds are constantly under siege from multiple threats.
As rain washes over roofs, pavement, farms, and grassy areas, and as snow melts and soaks into the ground, it picks up pollution and deposits it into surface water and groundwater.
![Page 13: Introduction The environment plays a big role on human health. Public health agencies decide policy based on the environmental factors at play in their.](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649dc95503460f94ac048a/html5/thumbnails/13.jpg)
3) Water PollutionThe pollutants may be
chemical or biohazardous in nature.
The may be put directly into the water table (i.e. a pipe from a factory or storm sewer drain in a city) or accumulate over time (i.e. storm runoff or the gradual leaching of fertilizer into the groundwater below).
![Page 14: Introduction The environment plays a big role on human health. Public health agencies decide policy based on the environmental factors at play in their.](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649dc95503460f94ac048a/html5/thumbnails/14.jpg)
3) Water PollutionExamples:
Fertilizer runoffFats and grease
from food processingInsecticidesHeavy metals from
carsAny number of lovely
pathogens from mismanaged sewage treatment or farming operations

3) Water PollutionPoor water quality is
the leading cause of sickness/illness in the world!
Polluted water leads to increased public health risks.
![Page 16: Introduction The environment plays a big role on human health. Public health agencies decide policy based on the environmental factors at play in their.](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649dc95503460f94ac048a/html5/thumbnails/16.jpg)
4) RadiationThankfully, radiation
is not as much of a health factor in Canada as in some countries.
The adverse health effects caused by radiation are usually not seen until long after the exposure.
![Page 17: Introduction The environment plays a big role on human health. Public health agencies decide policy based on the environmental factors at play in their.](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649dc95503460f94ac048a/html5/thumbnails/17.jpg)
4) RadiationMassive radiation
exposure or continual exposure over the long term cause serious public health issues.
It can have a lasting effect on a population due to the genetic effects and increased cancer risks.

1) Air Quality
One way to ensure health is maintained in the home is the avoid lowering the quality of air the circulates.
![Page 20: Introduction The environment plays a big role on human health. Public health agencies decide policy based on the environmental factors at play in their.](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649dc95503460f94ac048a/html5/thumbnails/20.jpg)
1) Air QualityThings that
deteriorate air quality:Cigarette smokeDustMouldChemicals (paint
thinner, gasoline, etc…)
![Page 21: Introduction The environment plays a big role on human health. Public health agencies decide policy based on the environmental factors at play in their.](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649dc95503460f94ac048a/html5/thumbnails/21.jpg)
1) Air QualityPoor air quality leads to
an increase in cases of asthma and allergies.
These are public health issues because increased allergies can lead to sensitivities to medications, while asthma can lead to an increased risk of future respiratory illness (i.e. H1N1 flu).
![Page 22: Introduction The environment plays a big role on human health. Public health agencies decide policy based on the environmental factors at play in their.](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649dc95503460f94ac048a/html5/thumbnails/22.jpg)
2) Clean Drinking WaterIn the United States,
91% of the people have drinking water that meets their federal clean water standards.
In Canada, the guidelines have been updated in 2008, so now, no one on Municipal water in Canada will be drinking substandard water.
![Page 23: Introduction The environment plays a big role on human health. Public health agencies decide policy based on the environmental factors at play in their.](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649dc95503460f94ac048a/html5/thumbnails/23.jpg)
2) Clean Drinking WaterClean drinking water
lowers the occurrence of water borne pathogens and their diseases.
This lowers the cost to public health and has many positive health benefits.
![Page 24: Introduction The environment plays a big role on human health. Public health agencies decide policy based on the environmental factors at play in their.](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649dc95503460f94ac048a/html5/thumbnails/24.jpg)
3) Existing Hazardous Substances
Many older homes, workplaces and even vehicles were made before the health hazards of many of the products used to build them were known.
![Page 25: Introduction The environment plays a big role on human health. Public health agencies decide policy based on the environmental factors at play in their.](https://reader035.fdocuments.in/reader035/viewer/2022062421/56649dc95503460f94ac048a/html5/thumbnails/25.jpg)
3) Existing Hazardous SubstancesAsbestos in the
insulation of older houses.
Lead in piping and in paints.

3) Existing Hazardous Substances
Radon/Carbon monoxide released from older appliances.
All lead to public health issues and all, thankfully, have been reduced in Canada.
