In the next step, we carried out the desorption of NO3 from the resin, in other words, regeneration of the resin, with high-concentration of NaCl solution and found that about 72 % of NO3 was desorbed from the resin. In the last step, we conducted catalytic decomposition of NO3 in the secondary wastewater generated by the regeneration of the resin and demonstrated that the Sn -Pd bimetallic catalyst successfully decomposed NO3 in the water along with low selectivity for undesirable NH3 formation even in the presence of high concentration NaCl. 107 23rd-25th June 2010 3rd ICYC 2010 Universiti Sains Malaysia ENV-P11 PROMOTION OF PUBLIC AWARENESS THROUGH THE ASSESSMENT OF AMBIENT AIR QUALITY: THE CASE OF TARLAC CITY, PHILIPPINES Xyris Gerard A. Fernandez, Maria Elena D. David and Lolita V. Sicat Tarlac State University, Romulo Boulevard, San Vicente, Tarlac City, Tarlac, Philippines E-mail: email@example.com This study aimed to monitor the level of air pollutant s in the ambient air of Tarlac City. Samples were collected from different parts of the city to evaluate which has the highest level of pollutants and the effect of seasons. Results were compared and interpreted using the standards specified in Republic Ac t 8749 otherwise known as the Clean Air Act of 1999. According to the Provincial Development and Physical Framework Plan (PDPFP) of Tarlac, there were no available data on air pollution levels in the different urban areas of the province. The Environmental Management Bureau (EMB), which is responsible for air quality monitoring, has not installed (as of May 2008) any monitoring station in the province to gauge the level of air pollutants in the area. Thus, in order to address this problem, the Tarlac State University Research Office has facilitated in the ambient air monitoring activities of the city. Parameters like sulfur dioxide (SO2), nitrogen dioxide (NO2), Total Suspended Particulates (TSP), carbon monoxide (CO), and lead (Pb) were analyzed and compared with the allowable limits given by the standards. The findings will be used for policy formulation...
