Carbon Monoxide level in different areas

"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

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 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 ?

Understanding the requirements

I want to be sure I understand the requirements:

1. Should I repeat the experiment in 5 different places? Should I insert 5 places in the map?

2. In the following site:

Carbon Monoxide count is divided to sources of cause, including cars.

Which number should I take (total count/ Monoxide count from cars)?

Data collected
I will start with the data that i have collected:
I did it for 5 times in the same place in adifferant hours:
    1. 12:36     23 cars
    2. 14:10     27 cars
    3. 16:15     45 cars
    4. 18:05     42 cars
    5. 20:00     31 cars
The level of Carbon Monoxide, from transportation in my 
current location: 175.2 [ppm]  the recommended amount is: 100[ppm] 
which means, that i live in a high risk area.

However there are additional data, which give us a "larger image" of the region,  that affecting the study.
such as :
1.the vecinity to the train rail.
 2.Many polluting factories in the region

my graph:

My conclusion:
After reading the topic, and understand the implications of carbon monoxide  and I learned about the relationship between carbon monoxide and vehicles.
After the study, I would rather not go for a walk and do other strenuous activities with my children at times when there is a load of cars in this region.
