<P><p><strong>Abstract.</strong> Exposure to particulate matter (PM) is a serious environmental problem in many urban areas on Earth. In the Philippines, most existing studies and emission inventories have mainly focused on point and mobile sources, while research involving human exposures to particulate pollutants is rare. This paper presents a method for estimating the amount of fine particulate (PM<sub>2.5</sub>) emissions in a test study site in the city of Cabanatuan, Nueva Ecija, in the Philippines, by utilizing local emission factors, regionally procured data, and land cover/land use (activity data) interpreted from satellite imagery. Geographic information system (GIS) software was used to map the estimated emissions in the study area. The present results suggest that vehicular emissions from motorcycles and tricycles, as well as fuels used by households (charcoal) and burning of agricultural waste, largely contribute to PM<sub>2.5</sub> emissions in Cabanatuan. Overall, the method used in this study can be applied in other small urbanizing cities, as long as on-site specific activity, emission factor, and satellite-imaged land cover data are available.</p> </P>

Winter squash 'Ebis' from Jeju Island cured for 10 days at 28±1℃ with RH of 70±5% were stored at 5℃, 12℃ and at ambient conditions for 6 months. Another batch of 'Ebis' and 'Kurijimang' from Anheung pre-treated with 200 ppm of NaOCl were stored at the same conditions for at least 4 months. Changes in quality and incidence of chilling injury were investigated. Good quality 'Ebis' can be stored for at least three months at low temperature storage. The development of chilling injury contributed much to a shortened storability. Manifestation of chilling injury in cured 'Ebis' started at 4 months storage while 'Ebis' from Anheung exhibited symptoms of the injury as early as two months. Chilling injury in 'Kurijimang', on the other hand, was apparent on the third month of storage. Chilling injury affected the firmness of both varieties by exhibiting reduction of flesh consistency. Weight loss was highest at room temperature storage while moisture loss was least at low temperature storage. Chilling injury contributed much to an increase in weight loss at 5℃ storage. The development of chilling injury was characterized by rind darkening and the development of pitting due to weakened tissues resulting in internal tissue breakdown following mold invasion.
