Environmental Exposures

1. Discuss why linking environmental pic to disease is difficult. As discussed by Stanhope and Lancaster (2010), the study of environmental epidemiology is difficult because of the multi tierity of the relationships amongst armament, factor, and environment. These three elements form the classic epidemiologic triangle. (p. 89) Additionally, these conceptual elements of the triangle crapper themselves be complex. The host may refer to a alliance spanning alter ages, genders, ethnicities, cultures, and disease states. (P.89) What make argon seen from the exposure of a host to an agent is dependent on some(prenominal) factors. Some examples of this variability in the host-agent interaction include enceinte women, and COPD sufferers. The fetuses of pregnant women are more than susceptible to the damaging tackuate of exposure to mercury than are an adult male. And a COPD unhurried is more susceptible to the effects of an elevated level of ozone, than is an several(prenominal) with healthy lungs. Environmental factors are plausibly the most complex of the three legs of the epidemiologic triangle. Before the agent can happen the host, it has to exist in and pass by dint of the ambient environment. some agent are unaffected by the environment. Air and rescind can dilute or distil agents.

Sunlight can break them down, as in the strip of some bacteria, or increase their levels, as in the parapraxis of ozone. And finally, as give tongue to by Stanhope and Lancaster (2010), the usefulness of epidemiologic studies is sometimes limited by the qualit y of the cause and effect data available. ! Studies are normally performed on healthy adults whose biological systems are quite different from those of neonates, pregnant women, children, the immunosuppressed, and older adults.
