Additionally, the concentration level was slightly elevated in the stationary samples compared to personal samples. This study affirms that workers can experience exposure to sulfuric acid, even in the absence of direct handling of the substance. Consequently, there is a need to recognize and ...
Accumulation of Sulfur Compounds At the Interface of Paint and Wood Following Exposure to Sulfurous Acid 来自 ResearchGate 喜欢 0 阅读量: 5 作者:RS Williams,TA Kuster,J Spence 摘要: Western redcedar (Thuja plicata) and southern pine (Pinus sp.) strips coated on all surfaces with acrylic ...
Repeated occupational exposure to sulfuric acid mists may increase the chance of lung cancer by up to 64 percent.[33] In the United States, the permissible exposure limit (PEL) for sulfuric acid is fixed at 1 mg/m3 : limits in other countries are similar. 但风险会因暴露时间的缩短而减少...

Dimethyl sulfate can be hydrolyzed to produce sulfuric acid, methyl sulfate and methanol, leading to irritation and even corrosive effects of eyes and respiratory tract after exposure. In our cases, the symptoms were delayed for several hours after the exposure, the reason of which might be the ...
(Cambridge Isotope Laboratories, Inc., Tewksbury, MA, USA), and 10 ml of concentrated sulfuric acid were added. The mixtures were violently shaken to remove lipids, and the organic phases were further purified using a multilayer silica–alumina column. The concentration of BDE-209 was quantified...
aAfter the usual processing, the liquor contains 250 to 260 gpl titanium dioxide, 40 gpl iron, and 500 gpl active sulfuric acid. 在通常处理以后,酒包含250到260 gpl二氧化钛、40 gpl铁和500 gpl活跃硫酸。[translate] a[10:38:15] wagner9990: Tu conoces a abby? (10:38: 15) wagner9990: You...
