Since oxides of sulphur and nitrogen cause serious air pollution, close attention is being paid to the sulphur content in petroleum products. The EPA has already set a maximum sulphur content of 1 % for petroleum products nationwide from July 1, and this will be brought down below 1 % by 1993. With this in mind, China Petroleum is already building a low-sulphur oil refinery at Talin, Kaohsiung.
我國由於硫與氮的氧化物引起嚴重的空氣汙染，因此油品的含硫量也受到重視；環保署已規定今年七月一日起，全國各界所使用的油含硫量不得超過百分之一，八二年更準備要降到百分之一以下；中油為此也正在高雄大林廠蓋低硫油煉油廠。
