Subject: acid spikes

Daw'r dyfyniad o ddarn sy'n trafod effeithiau glaw asid ar briddoedd ac afonydd Eryri:

 

Areas such as the Migneint have naturally acidic soils, but the added acidity from high rainfall and acid deposition means the buffering capacity of the moorland is unable to neutralise the high acid content resulting in acid spikes during high rainfall spates where the PH level can drop to below 4. 

 

Unrhyw awgrymiadau, os gwelwch yn dda?
