1. Hazard Identification:
According to abstract of article, it finds that human exposures to the hazard cigarette smoking have potential to cause the specific adverse health effect on colon cancer and other kinds of cancers such as colorectal cancer (Lindsay, et al, 2009). The method of exposure is direct inhalation of non-filtered cigarettes smoking. According to the abstract, it does not mention other means of exposure, such as by water, food or second and contact.
2. Dose Response: I will compare smoker versus non-smoker as a measure of dose response, and I will take into account the number of years as smoker. According to the first abstract, there is 27% an increased risk of colon cancer in current smokers versus 23% an increased risk …show more content…
In order to identify how many people are exposed, I chose the maximum smoking rate and then multiply by 100,000 and multiply by the total number of county of each smoking rate categories.
1. (20.4÷100) × 100,000 × 20= 408,000
2. (24.2÷100) × 100,000 × 27= 653,400
3. (27.2÷100) × 100,000 × 32= 870,400
4. (30.4÷100) × 100,000 × 21= 638,400
5. (36.5÷100) × 100,000 × 15= 547,500
The total number of people who are exposed is (408,000 + 653,400 + 870,400 + 638,400 + 547,500)= 3117700
4. Risk Characterization:
The total number of Missouri population is 5,659,984. In order to know how many unexposed people will get colorectal cancer, I will subtract the people who are exposed from the total number of population, and then I will take 5% of them, as we assume that 5 % unexposed people will get colorectal cancer. 5,659,984 – 3117700 = 2542284× (5÷100)= 127114.2
* We assume that 27% of exposed of current smokers are white. The number of white exposed people will get colorectal cancer is 3117700 ×(27÷100)= 841779
* We assume that 29.7% of exposed of current smokers are black. The number of black exposed people will get colorectal cancer is 3117700 ×(29.7÷100)=
