Webb22 mars 2024 · The average pH of precipitation in 2024 was between 3.27 and 8.20, as recorded by Environmental Quality in Hunan Province. The EMR1 (fresh residue) sample was collected directly from the industry’s discharge, while the EMR2 (out stockpiled) sample was collected from stacks exposed in an open field for more than 3 months. WebbNAPAP (1990) reports that all forms of precipitation over much of eastern North America, on average, are quite acidic (Fig. 3). Mean annual “wet” precipitation (weighted by the volume of each precipitation event) was in the range pH 5.0–4. Individual rain episodes with pH near 3.0 are observed in the northeastern United States.
