Essay About Traffic Volume

A Correlational Study on The Traffic Volume and Traffic related CO Concentration in Manila City

CHAPTER 1

I. Introduction

Due to the increasing number of vehicles especially in urban areas, the amount of air pollutants in the environment is directly affected. From vehicle operation , refuelling , manufacturing and disposal , cars and trucks emit air pollutants that directly travel into the atmosphere and undergo chemical reaction with other pollutants. The major pollutants that most vehicles produce are particulate matter (PM) , hydrocarbons (HC), carbon monoxide (CO), nitrogen oxide (NO), sulfur dioxide (SO2 ), hazardous air pollutants (toxics), and greenhouse gases (“Cars, Trucks, and Air Pollution” , 2014).

Carbon monoxide (CO) is a harmful colourless and odourless gas produced by burning material containing carbon. In the United States, vehicle emissions

Scope and Delimitation

This research focuses only on the levels of carbon monoxide emitted by vehicles and does not include information of other pollutants. In every location, the carbon monoxide detector was put only to a certain spot. The gathering of data lasted for three (3) hours each day including the time of usual rush hour in the evening and it was performed for seven ( 7) consecutive days for each location namely, Recto- Quiapo, España Boulevard, and Rizal Avenue.

This research does not focus directly for the researching of the effects of carbon monoxide but rather on the relationship of volume of vehicles to the CO concentration of air. It also focuses on the carboxyhemoglobin level (%COHb) that people can acquire and the possible effects of occupational exposure based on the studies of other researchers. Also due to time constraint, the researchers were not able to do the experiment in more locations and for a longer time have given the researchers a more accurate data.
