"Silent killer" - carbon monoxide is a poisonous gas that reduces the ability of hemoglobin binding oxygen and therefore is called the silent killer. In addition, it is considered one of the greenhouse gases that increases the greenhouse effect causing drastic climate changes. In the past, the source of carbon monoxide in the atmosphere were volcanic eruptions. But today , the main source of the atmospheric gas is due to constitutional burnning of natural gases, cooking gas, cigarette smoke, gasoline vehicles and wood burning.
You can see in the graph below the sources sector of national carbon monoxide :
Picture was taken from EPA website https://www3.epa.gov/cgi-bin/broker?polchoice=CO&_debug=0&_service=data&_program=dataprog.national_1.sas
In our research, we are interested to find out the association between the level of carbon monoxide gas in the atmosphere and numbers of vehicles passing in the street for duration of 5 minutes intervals in different places.
So in order for you to help us answering this question , you need to do the following steps :
1. download " Automatic Car Accounter " app to your smartphone .
2. start counting number of vehicles passing in front of you by using the app.
3. At the same time , visit the website http://www.sviva.gov.il/InfoServices/Tools/Pages/GIS.aspx in order to check out the level of carbon monoxide in your current location.
Repeat these two steps(2+3) above 5 times, then build a graph to summarize your results. what is your conclusion from this research ?
