Document Summary
Chapter #9: health impacts of global environment change. Of the radiation that does get through to the earth"s surface there is evidence that it can cause skin cancers and eye disease (cataracts) The rest of the section is about the science behind the ozone depletion, nothing really health related, so highly doubtful we need to know anything from it. Cumulative lifetime exposure to sunlight seems to be a risk factor for squamous cell carcinoma (scc) in particular, while adult risk of basal cell carcinoma (bcc) is considered to be related to sun exposure in childhood and adolescence. Those working outdoors, in farming and fishing, are at risk, with cancers on exposed body areas, such as the head and neck. The incidence of malignant melanoma (mm) is quite high in australia and new. Zealand, where considerable proportions of the population have fair skin.
