"To understand the chemical composition and temporal variations of atmospheric precipitation in Beijing, the precipitation samples were collected and analyzed continuously for two years. In 65 precipitation samples, 12% were acidic; annual precipitation acidity was mainly determined by summer precipitation. SO42-, NH4+, and Ca2+ were the most abundant components with their average concentrations all near or above 200 µg/L. Comparison analysis showed that in late years, the SO42- contribution to precipitation acidity was reduced markedly and its sulfur-pollution character was weaken, while that of NO3- was enhanced markedly. The concentrations of anthropogenic and crustal-elements were all higher in winter and spring while lowest in summer.

In comparison with stated normal amounts of aluminum found in the air.

(Quote) “…..Levels of aluminum in the air generally range from 0.005 to 0.18 micrograms (1 microgram, ?g, equals a millionth of a gram, 1 gram equals 0.0022 pound) of aluminum per cubic meter of air (0.005–0.18 ?g/m3 or 0.00018 mg/L) , depending on location, weather conditions, and level of industrial activity in the area. Most of the aluminum in the air is in the form of small suspended particles of soil (dust). Aluminum levels in urban and industrial areas may be higher and can range from 0.4 to 8.0 ?g/m3 ….”
