In Hong Kong, the Environmental Protection Department (EPD) started an acid rain monitoring program since the middle of 1980s. The present study was a desktop review exercise on the local available data in accessing the current situation of acid rain and its potential trend for the future. Acid rain data (wet and dry deposition) collected by the EPD stations and other sources were systematically reviewed and statistically analysed. The potential impacts by acid rain per se on the local ecosystems were assessed both in physical and monetary terms as far as possible. Major conclusions drawn the studies are listed below
