DDT Toxicity and Malaria Countermeasures
According to the CDC, in 2010 there were over 216 million cases of malaria that resulted in the 655,000 deaths (Centers for Disease Control and Prevention, 2012). The incidence of malaria and the concomitant death toll illustrate the acute need for effective measures of prevention. Furthermore, over 91% of the deaths from malaria occur in Africa and furthering the case of preventative measures (Centers for Disease Control and Prevention, 2012). Transmission of malaria via mosquitos illustrates the difficulty in both containment and eradication of the public health risk. The World Health Organization currently permits the use of indoor residual spraying (IRS) of 12 varieties of chemical insecticides as effective means to counter malaria. The use of DDT, a chemical significantly restricted under the Stockholm Convention on Persistent Organic Pollutants, is one of the permissible compounds available for IRS to combat malaria (World Health Organization, 2011, p. 1). The acceptance of applying DDT is the result of a cost-benefit analysis of regarding longer term efficacy of the chemical, cost, and effectiveness as well as practical considerations regarding a lack of alternatives that are neither readily available nor affordable to the areas in need.
DDT Risk Assessment
The dangers of DDT arise from concerns arising from its accumulation within the food chain and the current classification as a "probable carcinogen" to
