The environmental mobilization of contaminants by “natural disasters” is a subject of much interest; however, little has been done to address these concerns, especially in the developing world. Frequencies and predictability of events, both globally and regionally as well as the intensity, vary widely. It is clear that there are greater probabilities for mobilization of modern contaminants in sediments. Over the past 100 years of industrialization many chemicals are buried in riverine, estuarine and coastal sediments. There are a few studies, which have investigated this potential risk especially to human health. Studies that focus on extreme events need to determine the pre-existing baseline, determine the medium to long term fate and transport of contaminants and investigate aquatic and terrestrial pathways. Comprehensive studies are required to investigate the disease pathways and susceptibility for human health concerns.
The environmental mobilization of contaminants by “natural disasters” is a subject of much interest, however, little has been done to address these concerns, especially in the developing world. Frequencies and predictability of events, both globally and regionally as well as the intensity, vary widely. Vulnerability of people depends on whether they live in harms way in flood plains, on the coast, at or below sea level, or near streams or near areas of known contamination. Those people living closest to the source are most vulnerable. The intersection of natural disasters, contaminants and people is the subject of this paper. The coastal environment is becoming more vulnerable to damage from natural disasters. Sea-levels are rising, subsidence of land is increasing in some regions and decreasing in others. Upper ocean heat content is predicted to increase, atmospheric water content is increasing possible leading to more downpours, exacerbated flooding and general human misery. Coastal populations are increasing as people move closer to the coast increasing risk of greater damage. Also harmful algal bloom frequency, hypoxic or “dead zones” are becoming more prevalent and spills of various substances occur at regular frequency and variable intensity
