Proposed explanation, clearly marked as a hypothesis:
Other possible causes:
Measurement source / site / period / method / quality flags:

Fictional pH example: pH 4 versus pH 5 = 10 times hydrogen-ion activity; pH 4 versus pH 6 = 100 times.
This is not a total-pollution or damage ratio.
Rainfall amount / concentration / deposition quantity kept distinct:
