disodium tetraborate decahydrate, boric oxide (B203) and disodium octaborate tetrahydrate are likely to be similar on a boron equivalents basis. Therefore, it is justified to draw conclusions on boric oxide on the basis of data on studies on toxicokinetics and toxicity of other simple borates such as boric acid and the disodium tetraborates.Boric acid is almost completely absorbed orally by humans and animals (docu-mentation “Boric acid” 1993). Boric acid is hardly absorbed through the intact skin, but is through injured skin (documentation “Boric acid” 1993). Volunteers absorbed less than 0.5% of the Boric acid and tetraborates 3Boric acid and tetraborates Wiley Online Library
Garabrant et al. (1984) evaluated worker exposure to boron oxide and boric acid dusts. Boron oxide reacts exothermically with water to form boric acid suggesting a possible mechanism for boron oxide irritancy. The toxicokinetics of boric acid and disodium tetraborates are similar in rats and humans with regard to absorption, distributionBoric acid, boric oxide, disodium tetraborates, sodium perborates and crude borates for industrial use -- Determination of iron content -- 2,2'- Bipyridyl photometric method Newest version Withdrawn from 27.05.2002ISO 5933:1980 EVS standard evs.ee en

Often referred to as borates, boron oxide compounds find extensive industrial use. These compounds, in which boron is bonded exclusively to oxygen, are produced on a vastly larger scale than all other classes of boron compounds combined. Global consumption of borates in 2014 was estimated at 2.0 × 10 6 t of B 2 O 3 您的位置： 中国标准在线服务网 >> 全部标准分类 >> 国际标准 >> 71.060.01 >> ISO 5933:1980 EN e47dc108 Boric acid, boric oxide, disodium tetraborates and crude sodium borates for industrial use — Determination of ISO 5933:1980 EN e47dc108 Boricacid,boricoxide
