"Abstract
Eighteen rain samples from Israel have been analyzed for their chemical composition and 87Sr/86Sr ratios. The Sr-isotopic ratios lie in the range 0.7078 and 0.7092, and the Sr concentrations vary from 1 × 10-4 to 9 × 10-4 meq Sr/l.

Soluble salts in rainwater are inherited from three major natural sources, seaspray, Recent marine minerals and mineral dust eroded from rock outcrops and soil. A mixing model is formulated to apply the chemical composition of rain (Cl- and Sr2+) and its isotopic 87Sr/86Sr ratio, for the identification and estimation of the Sr sources. All the samples fall within the mixing space predicted by the model for the three end members mentioned above. The data indicate that the most important non-seaspray source contributing dissolved salts to the rains in Israel comprises a mixture of Senonian to Eocene chalk (and its weathering products) and Recent marine minerals, from local and imported sources.

Most of the samples (67%) contain 50% or more non-seaspray Sr (i.e., Sr dissolved from dust or Recent marine minerals), whereas 56% of the samples display87Sr/86Sr ratios lower than 0.7090. The rest represent mixtures of seaspray and Recent marine minerals."

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 ….”
