This is your presentatio n title Situation and Trends Ambient Air Pollution  Air pollution is a major environmental issue affecting people across the world According to the World Health Organisation (WHO), more than million people worldwide die every year from air pollution ● the population of Asia and the Pacific is among the most highly exposed to PM2.5 in the world Indoor Air Pollution ● Globally, the number of annual deaths from indoor air pollution has fallen by more than million since 1990 ● This means that despite continued population growth in recent decades, the total number of deaths from indoor air pollution has still declined Health affected by air pollution ● Fewer than percent of the region’s people are exposed to levels of air pollution that not pose a significant risk to their health according to the World Health Organization (WHO) Guideline.  ● WHO estimates that in 2016, some 58% of outdoor air pollution-related premature deaths were due to ischaemic heart disease and strokes Causes Ambient Air Pollution  ● Common sources of air pollution are emissions caused by combustion processes from motor vehicles, solid fuel burning and industry ○ ○ ○ ○ ○ Urbanization source Stationary Sources Mobile Sources  Rural Area Sources  Marine Emissions Household Air Pollution  ● Air pollution is now considered the world's biggest environmental health threat Half of the world's population has no access to clean fuels or resources, out of 10 people are inhaling polluted air, and up to million people are killed each year because of air pollution ● The impact of air pollution on human health is increasingly concerned “ Quotations are commonly printed as a means of inspiration and to invoke philosophical thoughts from the reader 10 Valuation of air pollution’s effect on healthcare expenditure ● The analysis involved two steps: ○ Measure the reductions in PM2.5 and ozone concentration levels throughout the area for our air quality improvement scenario ○ Quantify potential spending reductions  11 “ ● China managed to calculate that for every 10 μg/m3 decrease in PM2.5 concentration, a reduction of billion $ in healthcare expenditure for air pollution will occur.  ● In order to convert this data into the Asia’s healthcare expenditure for air pollution, we will have assumptions ○ in order to reduce 10 μg/m3 in PM2.5 concentration, Asia as a whole will need at least billion $ ○ at any level, a 10 μg/m3 decrease in PM2.5 concentration will always results in  a reduction of billion $ in healthcare expenditure for air pollution and vice versa 12 From the table above, we can calculate the mean level of PM2.5 concentration in Asia is about 21,56 μg/m3 Therefore, follow our function above, we come to conclusion that the healthcare expenditure for air pollution in Asia is at least 19,5 billion $ 13
