“…On the other hand, it is known that sea salt degassing from oceans and volcanic emissions are the major sources of boron in the atmosphere (Fogg and Duce, 1985;Anderson et al, 1994). The boron concentration and isotopic composition of seawater are nearly constant in all the oceans, being approximately 4.5 µg L -1 and +39.5‰, respectively, although boron isotopes are fractionated largely during seawater evaporation.…”

Isotopic evidence of boron in precipitation originating from coal burning in Asian continent

The boron concentration and isotopic composition (δ 11 B) of precipitation collected from December 2002 to March 2006 at three sites on the Japan Sea coast were measured. Those sites have been considerably affected by the long-range transport of air pollutants from the Asian continent during winter and spring when the airflows from the Asian continent are predominant. The boron concentration in the precipitation increased primarily during winter whereas the δ 11 B decreased during winter or spring. It is assumed that this decrease in δ 11 B is not associated with a Rayleigh distillation process, because the previous δD values of the precipitation collected at a site on the Japan Sea coast did not decrease in the same manner. A weak correlation (r 2 = 0.13-0.24, P < 0.01) was observed between δ 11 B and the nonsea-salt sulfate (nss-SO 4 2-)/B ratio at each site, suggesting that boron in the precipitation originate primarily from two sources. The first source, which is characterized by high δ 11 B and nss-SO 4 2-/B = 0, is seawater. At the northern site, the enrichment factor for boron in the precipitation relative to seawater approached unity during winter. This implies that much of the boron in the precipitation is derived from unfractionated sea salts rather than gaseous boron evaporated from seawater. The second source is characterized by low δ 11 B and high nss-SO 4 2-/B ratio. Most of the nss-SO 4 2-in the precipitation originates from anthropogenic combustion activities in the Asian continent based on the previous model calculations. Coal accounts for a major portion of the total primary energy supply in China. Moreover, coal enriches boron and represents generally negative δ 11 B values. Hence, we propose that the emission of boron from coal burning is the most likely second source. Thus, boron isotopes may be useful as tracers of coal-burning plumes from the Asian continent.

“…Boron has been found to come primarily from the ocean and secondarily is emitted by coal-fired power plants. 29 There could also be some emission from refuse incineration, but there are no adequate measurements to determine the contribution of these sources. Germanium, like boron, is generally enriched in the organic matter in coal, 30 and thus is likely to be emitted primarily by coal-fired power plants.…”

Two types of potential source contribution function analysis-Potential Source Contribution Function (PSCF) and Total Potential Source Contribution Function (TPSCF) analysiswere employed to study the source-receptor relationships for several trace elements (vanadium, selenium, arsenic, manganese, and indium) found in precipitation and airborne particles collected at Dorset, Ontario. This study identified areas in the United States and Canada as possible emission source areas that could contribute to the trace element concentrations observed at Dorset. The identified regions in the United States generally coincide well with the locations of known emission sources, whereas the possible source regions revealed in Canada could not be adequately explained because of the absence of emission source information. The likely emission sources for these trace elements include oiland coal-fired power plants, incinerators, motor vehicles, nonferrous metal smelters, iron and steel mills, ferrous-Mn alloy plants, and Mn chemicals production.

“…Fogg and Duce (1985) calculated the gaseous flux of B from volcanoes as 2.1 9 10 9 kg B year -1 , based on a single value for the B/SO 2 ratio of 0.14 in volcanic emanations and an estimate of the annual flux of SO 2 from volcanoes worldwide. Anderson et al (1994) supposed that this B/SO 2 ratio (available from Fogg and Duce 1985) was unusually high. The authors used a mean B/SO 2 ratio of 0.02 from Mount St. Helens (only) to calculate global volcanic emissions of 0.24 9 10 9 kg B year -1 , using an estimate of 10 9 kg S year -1 as the annual flux of SO 2 from volcanoes.…”

Boron sources, speciation and its potential impact on health

The behaviour of boron (B) and its fate in the environment remains in many respects obscure. The major B sources and fluxes seem to have been identified, although there are many uncertainties about the magnitude and importance of each; published evaluations vary greatly. Little is known about B speciation of living matter-bearing formations, i.e. soils, natural waters, and sediments. Many authors suppose that B in nature occurs only as oxocompounds, although, natural inorganic and organic B compounds and complexes have been described. Moreover, the most common approach to B biogeochemistry in terms of inorganic B compounds (as boric acid and borates) seems to oversimplify the matter. Data on the physiological functions of B are fragmentary and often contradictory. Some data exists on endemic symptoms and diseases among humans and grazing cattle that are supposedly triggered by B abundance in the natural environment. Unfortunately, the published data are scarce and vague. In this paper, we review the up-to date references on B sources, turnover, and speciation in the environment and the element potential impact on health.
