| Title | Global biochemical cycle of boron | Type | Journal Article | ||
| Year | 2002 | Publication | Global Biogeochemical Cycles | Abbreviated Journal | |
| Volume | 16 | Issue | Pages | 1072 | |
| Keywords | |||||
| Abstract | The global Boron (B) cycle is primarily driven by a large flux (1.44 Tg B/yr) through the atmosphere derived from seasalt aerosols. Other significant sources of atmospheric boron include emissions during the combustion of biomass (0.26-0.43 Tg B/yr) and coal, which adds 0.20 Tg B/yr as an anthropogenic contribution. These known inputs to the atmosphere cannot account for the boron removed from the atmosphere during rainfall (3.0 Tg B/yr) and estimated dry deposition (1.3-2.7 Tg B/yr). In addition to atmospheric deposition, rock weathering is a source of boron (0.19 Tg B/yr) for terrestrial ecosystems, and humans mine about 0.31 Tg B/yr from the Earth's crust. More than 4.8 Tg B/yr circulates in the biogeochemical cycle of land plants, and about 0.53-0.63 Tg B/yr is carried from land to sea by rivers. The biogeochemical cycle of boron in the sea includes 4.4 Tg B/yr circulating in the marine biosphere, and an annual loss of 0.47 Tg B/yr to the oceanic crust via a variety of sedimentary processes that collectively remove only a small fraction of the total annual inputs to the oceans. Thus with our current understanding of the global biogeochemistry of B, the atmospheric budget shows outputs > inputs, while the marine compartments show inputs > outputs. Despite these uncertainties, it is clear that the human perturbation of the global B cycle has more than doubled the mobilization of B from the crust and contributes significantly to the B transport in rivers. | ||||

| Title | Strontium in rainwater from Israel: sources, isotopes and chemistry | Type | Journal Article | ||
| Year | 1993 | Publication | Earth and Planetary Science Letters | Abbreviated Journal | |
| Volume | 120 | Issue | 1-2 | Pages | 77-84 |
| Keywords | |||||
| Abstract | Eighteen ram samples from Israel have been analyzed for their chemical composmon and S7Sr/S6Sr ratios The Sr-Isotoplc rahos lie In the range 0 7078 and 0 7092, and the Sr concentrations vary from 1 × 10 -4 to 9 x 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 soft A mixing model is formulated to apply the chemical composmon of rain (CI and Sr 2+) and ~ts isotopic 87Sr/S6Sr ratio, for the identification and est~mahon of the Sr sources. All the samples fall within the m~xing space predicted by the model for the three end members mentioned above The data indicate that the most important non-seaspray source contributing d~ssolved salts to the rams m Israel comprises a mixture of Senoman 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 0 e, Sr dissolved from dust or Recent marine minerals), whereas 56% of the samples display 87Sr/86Sr ratios lower than 0 7090. The rest represent mixtures of seaspray and Recent marine minerals. |
