LATEST reported figures show just one loch in the Borders is affected by acid rain.
Carter Loch is the only local freshwater loch registering levels of chemicals that could harm wildlife. Contaminants are sulphur, nitrogen and ammonia, which are likely to have come from vehicles, farms and other sources.
An SNH spokesperson said: “The Borders is probably less affected than elsewhere because of its geology. The rocks and soils are a bit of a buffer against the affects of acid rain, which means the fresh waters are less vulnerable to acidification. Carter Loch is right in the head waters of the Borders and it may be it’s (acidification) due to thinner soil and acid-sensitive rocks there.”
