Environmental Hazards and Disasters
Discussed in this chapter are conditions that are pandemic, i.e. widespread and hence impact large numbers of people at more or less the same time; as distinct from those that people are exposed to one at a time. Most such potential dangers are controllable, but one, organic mercury, presents a risk that is not wholly avoidable. Only one is a ‘natural’ happening, as distinct from the others, which are the products of human action.
