methods. In the research process, the researchers used the location data of 3 Air Quality Monitoring stations in

Chon Buri Province, namely the air quality monitoring stations in ThungSukla Subdistrict, Bowin Subdistrict,

and Ban Suan Subdistrict, and employed the data on gases that cause air pollution, two types of gases, carbon

monoxide sulfur dioxide for the result analysis and evaluation. It is found that the entire district of Mueang

Chon Buri and Sriracha District has a total area of approximately 879.364 square kilometers wherein the

distribution of carbon monoxide gas and sulfur dioxide is found in large quantities. In addition, the analysis of

air pollution risky areas in both districts indicates that there are sources of air pollution scattered along traffic

lights, intersections, 80 intersections, 13 parking lots, 90 garages, 281 industrial factories, 156 major roads, and

5,866 minor roads, while the most affected by air pollution are health and environmental impacts (𝑥 = 3.55).

world are facing air pollution problems. The cause

of air pollution can be caused by nature such as dust

problems from wind storms, volcanic eruptions,

earthquakes, forest fires, and natural gas, and,

another is caused by human actions such as

pollution caused by cars, industries, machinery, and

construction, etc., [1]. However, polluted air caused

by nature has little effect and poses no danger to

humans because the source of the problem is far

away and the amount of pollutants entering the

Such pollution will affect human health in a wide

range like allergies, respiratory diseases, and

Bowin Subdistrict, Sriracha District, it is 36

micrograms per cubic meter. Like ThungSukla

Subdistrict, Sriracha District, PM2.5 is at 45

micrograms per cubic meter, which is in the

moderate quality criteria according to the criteria of

the Air Quality Index (AQI), [4], and, it tends to

continue to increase and affect human health and

living beings for a long term, [5].

Hence, the present study aims at integrating the

knowledge and efficiency of the Geographic

stored as a database, building data layers to create a

map showing the distribution and a map showing

the areas at risk of air pollution caused by vehicles

more clearly. Also, this research provides useful

information about the distribution and factors

caused by pollution by automobiles. As a result, it is

possible to analyze the risky areas in Sriracha

District and Mueang Chon Buri District, Chon Buri

Province. When there is data on the effects of air

2 Literature Review

Air pollution refers to an air conditioner that

contains impurities or floating in the air that we

inhale. Even though it may not be visible, such as

dust, natural gas, or pollution from car exhaust

pipes, etc., it is considered a threat to our physical

body that can create a lot of impact and danger to

our health, [6].

level of pollution constantly entering the body, even

with a strong immune system when inhaling toxic

air for a long time, it also affects the body because

the air dirty by spreading in the air throughout the
