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 strivingity of the relationships amongst legion, element, 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 varied ages, genders, ethnicities, cultures, and disease states. (P.89) What make ar 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 much susceptible to the damaging personal lay outs 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 credibly 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 means of the ambient environment. some agent are unaffected by the environment. Air and rescind can dilute or sign agents.

Sunlight can break them down, as in the upshot of some bacteria, or increase their levels, as in the fictitious character of ozone. And finally, as give tongue to by Stanhope and Lancaster (2010), the usefulness of epidemiologic studies is sometimes limite d by the quality of the cause and effect dat! a 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.
