Where does acid rain occur in Philippines?

Acid rain in the Philippines primarily occurs in urban areas with high levels of industrial activity and vehicular emissions, particularly in cities like Manila and Cebu. The presence of sulfur dioxide and nitrogen oxides from these sources contributes to the formation of acid rain. Additionally, regions near volcanic activity, such as those around Mayon Volcano, may also experience acid rain due to volcanic gases. Overall, areas with significant pollution levels are most affected.
