ics to determine the positive and negative correlations between and among the prevalence and incidence of pulmonary diseases among employees and the heterogeneous contributory factors such as the duration exposure to unleaded gasoline, employee position and work practices at Nalco in Manila.
This researcher suggests unleaded gasoline use for the benefit of all employees in particular and people in general in the Philippines. This research focuses on many related aspects such as short-term and long-term social costs and benefits. While social costs of not using unleaded gasoline and its impact on health of the people in the Philippines would be investigated with reference to Nalco, benefits would be investigated with general reference to a larger population sample in the Philippines. The study in full would investigate health, social, economic and the environmental impact.
Environmental organizations and critics in the Philippines have time and again pointed out that the Filipinos’ state of health, especially in Manila, has been deteriorating over the years primarily due to air pollution caused by the ever increasing use of leaded gasoline (Brandon et al 2007; Sastry 2002). These critics have particularly sought to focus attention on the causal factor of using leaded gasoline as a direct impacting agent on the general health factor of the nation (Louella et al. 2006). This state of affairs particularly warrants a comprehensive HIA in Manila.
A series of health impact assessments will be made in this HIA to analyze the existing literature on the extent and the incidence of negative health effects on the Filipinos. One of the health impacts would be focused on the verifiable statistical measures such as the mean, the mode and the median population samples that have been affected within a particular locality (AHA 2010). Manilans become the central point of focus while most of the theoretical and conceptual references would be focused on the Nalco employees. Next,
