A cid Rain is killing the rivers of Nova Scotia. Acid precipitation is produced from sulphur dioxide and nitrogen dioxide emitted from burning oil, natural gas and coal.
Motor vehicles emit nitrogen oxide.
Metal smelters emit sulphur dioxide. These gases combine with water in the atmosphere to form nitric and sulphuric acids, and are dispersed by winds before falling back to earth in the form of rain, dew, snow, sleet and fog, harming plant and animal life. It is coming out just as snow melt is providing maximum impact of acid rain on Nova Scotia rivers. Another 50 rivers have been seriously impacted. These numbers will grow unless the Canadian and US governments adopt stricter emission laws.
