Dylan Winter visits Forfar Loch in Scotland
Dylan Winter looks at the problem of pollution caused by phosphates entering freshwater lochs.ÌýÌý
High concentrationsÌýof these chemicals cause algal bloomsÌýon theÌýsurface of the water in summer. This layer of algaeÌýprevents light penetratingÌýso the plants belowÌýcan't photosynthesise. This can affect the whole food chain.
While it's a nationwide issue, DylanÌýtravels to Scotland to look at how conservation bodies and organisations are tackling the problem.
At Marlee Loch, part of the Lunan Lochs chain near Blairgowrie, Scottish Natural Heritage are working with farmers to change farming practicesÌýand avoid phosphorus entering the water courses.
At Forfar Loch it's phosphates from household waste water that cause the problem.Ìý Here,Ìýto improve the quality of the water and so benefit wildlife, the waste water treatment works has been upgraded and a Watersense Campaign has been launched, educating people about using low phosphate or phosphate free products in their washing machines and dishwashers.
