This presentation explains about indoor airquality. And about the cause of indoor airpollution. And about its impact on human health. And interventions to reduce the burden of disease. And about pheumonia. About ischaemic heart disease. About chronic obstruction pulmonary disease. And about stroke and lung cancer.

1. AND HUMAN HEALTH

2. What is indoor air quality ?
What causes indoor air pollution ?
Impact on health.
Interventions to reduce the burden of disease
from SFU

3. INDOOR AIR QUALITY
Indoor air quality (IAQ) is
the air quality within and around
buildings and structures.
IAQ is known to affect the
health, comfort and well-being of
building occupants.
Poor indoor air quality has been
linked to sick building syndrome,
reduced productivity and
impaired learning in schools.

4. Main source of indoor air
pollution
Solid fuels burned in inefficient and highly
polluting stoves for cooking and heating.
Solid fuels: wood, animal dung, charcoal, crop
wastes and coal.
The resulting household air pollution led to more
than 4 million premature deaths among children
and adults in 2012.
Tobacco smoke.

5. Impact on health
3.8 million people a year die prematurely from illness
attributable to the household air pollution caused by the
inefficient use of solid fuels and kerosene for cooking.
27% are due to pneumonia,
27% from ischaemic heart disease,
20% from chronic obstructive pulmonary disease (COPD),
18% from stroke,
8% from lung cancer.

6. Other outcomes such as tuberculosis, asthma,
cataracts, still birth, low birth weight, perinatal
death and also aero-digestive tract cancer.

7. Pneumonia
Exposure to household air pollution almost
doubles the risk for childhood pneumonia and is
responsible for 45% of all pneumonia deaths in
children less than 5 years old.
Household air pollution is also risk for acute
lower respiratory infections (pneumonia) in
adults, and contributes to 28% of all adult deaths
to pneumonia.

10. ischaemic heart disease
Approximately 11% of all
deaths due to ischaemic heart
disease, accounting for over a
million premature deaths
annually, can be attributed to
exposure to household air
pollution.

11. chronic obstructive
pulmonary disease (COPD)
Women exposed to high levels of indoor smoke
are more than twice as likely to suffer from
COPD than women who use cleaner fuels and
technologies.
Among men (who already have a heightened risk
of COPD due to their higher rates of smoking),
exposure to household air pollution nearly
doubles that risk.

14. Stroke

15. Lung cancer
The risk for women is higher, due to their role in food prep

17. Carbon
monoxide
Reduced oxygen in
mothers blood.
Smoke
exposure
Cooking smoke
Tobacco smoke
(active and
passive)
Reduced oxygen
delivery to placenta.
Particulate matters
and other
pollutants.
Reduced maternal
lung function and
other lung diseases.
Reduced oxygen
supply to placenta.
Reduced nutritional
intake and reduced
nutritional delivery
to the foetus.
Impaired foetal
growth,
increased risk of
still birth,
reduced birth
weight, and
other adverse
pregnancy
outcomes.
Possible mechanisms by which exposure to solid fuel smoke and tobacco smoke might
cause adverse pregnancy outcomes

19. Interventions to reduce the
burden of disease from SFU
behavioural modifications to reduce exposure
(e.g. encouraging mothers to keep their young
babies away from the fire)
household changes to improve ventilation (e.g.
increasing the number of window openings in
the kitchen, providing gaps between the roof and
walls, or moving the stove out of the living area)

20. improvements to cooking stoves (e.g. ventilation
by flues, hoods or chimneys, or increases in
combustion efficiency - nearly all pollutants
damaging to health are products of incomplete
combustion).
interventions to enable people to use higher-
quality, lower-emission liquid or gaseous fuels
(e.g. petroleum-based kerosene and liquid
petroleum gas, or biomass-based alcohol and
bio-gas).
