It indicates that lead nitrate and nickel chloride have obvious reproductive toxicity.
提示,*********、氯化镍有明显的生殖毒性。
The experimental principle, process and conditions using waste powder containing lead to produce lead sulfate and lead nitrate are introduced.
本文介绍了由含铅粉尘制备*********及硝酸铅的原理、实验流程及实验操作条件。
The result shows that the nitrate contents in vegetables has surpassed the standard content set by the World Health Organization. Lead and mercury contents have also surpassed a half.
结果表明,蔬菜的硝酸盐含量均值已超过世界健康组织规定的含量标准,铅、汞含量也有一半以上超标。
The continuous determination of arsenic and lead in the solution of the same sample by spectrophotometry is described, based on the reaction between hydrides and silver nitrate.
本文提出了以氢化物与*********反应为基础的在一份试样溶液中连续测定微量砷和铅的分光光度法。
Alveolar oxygen into nitrogen compounds, lead to the formation of nitrite and nitrate, a sharp stimulus to the lung tissue, increased pulmonary capillary permeability, leading to emphysema.
氮氧化合物进入肺泡后,能形成亚硝酸和硝酸,对肺组织产生剧烈的刺激作用,增加肺毛细管的通透性,最后造成肺气肿。
“Lead nitrate”是由“lead”(铅)和“nitrate”(硝酸盐)组成的化合物,以下是详细解释:
Lead(铅)
化学元素符号为Pb(拉丁语Plumbum),是一种重金属,常见于矿物中。在化学中,铅通常以+2或+4价态存在,此处为+2价。
Nitrate(硝酸盐)
硝酸根离子(NO₃⁻)的盐类或酯类化合物,由硝酸(HNO₃)衍生而来。
铅化合物具有毒性,接触或吸入可能导致中毒,需严格遵循实验室安全规范。
总结来看,“lead nitrate”是以铅和硝酸根为核心的无机化合物,兼具明确的化学性质与应用场景。
lead nitrate是指一种化学物质,化学式为Pb(NO3)2,是一种白色晶体粉末,在室温下易溶于水。
lead nitrate通常用于制造染料、炸药、火柴、烟花和玻璃等产品。此外,它还可用作防腐剂、生产蓄电池和其他化学试剂。
lead nitrate是一种有毒物质,吸入或摄入它会对人体健康造成严重影响。如果不慎接触到该物质,应立即用大量水清洗受影响的区域,并寻求医疗救助。
