Acid rain Surveys

The last update date:

pH Surveys of rainwater which we gathered in Saga Environmental Research Center (Saga-shi)

We gather rainwater with automatic rainwater collection container which we installed in the roof and, in Saga Environmental Research Center (Saga-shi), measure pH that is important index of acid rain Surveys.
In addition, rainy pH measures these various ion concentration to be selected with balance of (ammonium ion and calcium ion) for Kazunari among acid ingredients (AEON sulfate nitric acid ion) in the rain.

Acid rain

Than pH 5.6 rain which is heavy (pH is small) of acidity.
Because atmospheric carbon dioxide melts into, by rain which pollutants such as sulfur oxide drained from factory and car do not melt into, as for normal rainy pH, it is rain in about 5.6 (subacidity).
