A plan for an epidemiological study will be presented based on the findings of the previously mentioned sections. Then a final overview will be presented, where we will address the information has been provided.
2. Exposure Media The exposure media is the environmental medium that contains the pesticide. In order for there to be an exposure a receptor, an individual or population, must come into contact with the environmental medium (Simon, 2014). The environmental mediums are soil, water, air, and biota. The concentration of the pesticide present must be determined in order to calculate a dose. Also, with each individual medium there will be a level of variability and uncertainty that must be considered. Contamination concentrations in the soil will be highly variable. This is due to the application of the pesticide. The areas directly where the pesticide was applied will have the highest concentrations. As you move away from those areas the concentration should decrease. Although they can remain high due to runoff, and wind deposits. The soil depth must also be considered. The surface soil will have the highest concentration. As the pesticide leaches through the soil the …show more content…
The closest body of water is 50 miles away, therefore the primary concern with water is with the underground water table. The groundwater is used for domestic/residential purposes as well as agricultural purposes. The best way to determine the concentration in the groundwater would be to collect samples directly from the wells located in the area. Water samples should also be collected from residences and businesses. All the wells should be tested. The area should be divided into section, north, northeast, northwest, south, southeast, and southwest. From each section ten indoor water samples should be collected. By comparing the indoor samples by region and to the well samples we will be able to statistically account for the variability in the water samples. If we find the concentration to be statistically higher in the indoor samples it will be necessary to collect more samples from each
