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 conformityity of the relationships amongst emcee, divisor, and environment. These three elements form the classic epidemiological triangle. (p. 89) Additionally, these conceptual elements of the triangle crapper themselves be complex. The host may refer to a alliance spanning vary ages, genders, ethnicities, cultures, and disease states. (P.89) What make be 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(prenominal) susceptible to the damaging personal accomplishments of exposure to mercury than are an adult male. And a COPD unhurried is more susceptible to the effects of an elevat ed 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 through the ambient environment. some agent are unaffected by the environment. Air and rescind can dilute or melt off agents.

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