The Provincial Government of Palawan held a seminar/workshop on WATER CONSERVATION with assistance from the Center of Public Health&Environmental Sciences in Tokushima Prefecture on July 3-4, 2000 at the Legend Hotel, Puerto Princesa City , Palawan. We took advantage of this opportunity and carried out an investigation of the toxic air pollutants on Palawan. As a result of the air quality survey carried out on Ju}y 6th and 7th, we found the following air quality features. 1) The trichloroethylene, tetrachloroethlene and the ozone layer depletion substances levels were almost the same as Japanese results and there was no problem. 2) The benzene level at the Puerto Princesa airport site was 4.5 times higher than the standard value in Japan and the level at the Immaculate Conception Cathedral site was 2.6 times higher. These sites are near main road and they have some effects due to exhaust gases from vehicles. 3) The 1.3-butadiene results showed a high concentration at the Puerto Princesa airport site and Immaculate Conception Cathedral site. The main cause of the 1.3-butadiene pollution is also exhaust gases, too.
