代谢
溴主要通过吸入进入人体,但也可以通过皮肤接触。溴盐可以通过摄入进入人体。由于溴的活性,它会迅速形成溴化物,并可能沉积在组织中,取代其他卤素。
Bromine is mainly absorbed via inhalation, but may also enter the body through dermal contact. Bromine salts can be ingested. Due to its reactivity, bromine quickly forms bromide and may be deposited in the tissues, displacing other halogens. (L626)

  • 毒性总结
溴是一种强大的氧化剂,能够从粘膜组织中的水分解出氧自由基。这些自由基也是有力的氧化剂,会导致组织损伤。此外,氢溴酸和溴酸的形成会导致二次刺激。溴离子还已知会影响中枢神经系统,导致溴中毒。这被认为是因为溴离子取代了神经递质和传输系统中的氯离子,从而影响了众多的突触过程。(L626, L627, A543)
Bromine is a powerful oxidizing agent and is able to release oxygen free radicals from the water in mucous membranes. These free radicals are also potent oxidizers and produce tissue damage. In additon, the formation of hydrobromic and bromic acids will result in secondary irritation. The bromide ion is also known to affect the central nervous system, causing bromism. This is believed to be a result of bromide ions substituting for chloride ions in the in actions of neurotransmitters and transport systems, thus affecting numerous synaptic processes.

  • 健康影响
溴蒸气会引起刺激和对粘膜的直接损害。元素溴也会烧伤皮肤。溴化物离子是一种中枢神经系统抑制剂,长期暴露会产生神经元效应。这被称为溴中毒,可能导致从中枢反应嗜睡到昏迷、恶病质、昏迷、反射丧失或病理反射、阵挛性癫痫、震颤、共济失调、神经敏感性丧失、瘫痪、眼乳头水肿、异常言语、脑水肿、谵妄、攻击性和精神疾病等症状。
Bromine vapour causes irritation and direct damage to the mucous membranes. Elemental bromine also burns the skin. The bromide ion is a central nervous system depressant and chronic exposure produces neuronal effects. This is called bromism and can result in central reactions reaching from somnolence to coma, cachexia, exicosis, loss of reflexes or pathologic reflexes, clonic seizures, tremor, ataxia, loss of neural sensitivity, paresis, papillar edema of the eyes, abnormal speech, cerebral edema, delirium, aggressiveness, and psychoses.

  • 症状
溴蒸汽会引起刺激和对粘膜的直接损害。症状包括流泪、流鼻涕、眼部刺激伴有来自口咽和上呼吸道的粘液分泌、咳嗽、呼吸困难、窒息、喘息、鼻出血和头痛。溴离子是一种中枢神经系统抑制剂,会引起共济失调、言语不清、震颤、恶心、呕吐、乏力、眩晕、视觉障碍、不稳、头痛、记忆和注意力受损、定向障碍和幻觉。这被称为溴中毒。
Bromine vapour causes irritation and direct damage to the mucous membranes. Symptoms include lacrimation, rhinorrhoea, eye irritation with mucous secretions from the oropharyngeal and upper airways, coughing, dyspnoea, choking, wheezing, epistaxis, and headache. The bromide ion is a central nervous system depressant producing ataxia, slurred speech, tremor, nausea, vomiting, lethargy, dizziness, visual disturbances, unsteadiness, headaches, impaired memory and concentration, disorientation and hallucinations. This is called bromism. (L626, L627)

    fluorescence technique has been employed to investigate the kinetics of reactions of the important stratospheric species bromine nitrate (BrONO2) with ground-state atomic bromine (k1), chlorine (k2), and oxygen (k3) as a function of temperature (224−352 K) and pressure (16−250 Torr of N2). The rate coefficients for all three reactions are found to be independent of pressure and to increase with decreasing

    Kinetics for reactions of OBrO with NO, OClO, and ClO were examined using discharge flow coupled with mass spectrometer (DF/MS) technique at 298 K and total pressure of 1 torr under the pseudo-first-order condition in which OBrO was a minor reactant. The rate constant for the reaction of OBrO with NO was determined to be k2=(1.77±0.32)×10−12 cm3 molecule−1 s−1. NO2 was found to be the product for OBrO+NO
    使用排出流结合质谱仪(DF / MS)技术在假一阶条件下(OBrO为次要条件)在298 K和总压力为1 torr的条件下检查了OBrO与NO,OClO和ClO的反应动力学。反应物。确定OBrO与NO的反应的速率常数为k 2=(1.77±0.32)×10 -12 cm 3分子-1 s -1。发现NO 2是OBrO + NO的产物。OBrO与OClO和ClO反应的速率常数估计为k 3 <3×10 -14和k 4 <1×10 -13 cm 3分子-1 s -1。

    Chloride ion catalyzes the reactions of HOBr with bromite and chlorite ions in phosphate buffer (p[H(+)] 5 to 7). Bromine chloride is generated in situ in small equilibrium concentrations by the addition of excess Cl(-) to HOBr. In the BrCl/ClO(2)(-) reaction, where ClO(2)(-) is in excess, a first-order rate of formation of ClO(2) is observed that depends on the HOBr concentration. The rate dependencies
    氯离子催化HOBr与溴酸根和亚氯酸根离子在磷酸盐缓冲液(p [H(+)] 5至7)中的反应。通过向HOBr中添加过量的Cl(-),可在较低的平衡浓度下原位生成氯化溴。在BrCl / ClO(2)(-)反应中,ClO(2)(-)过量,观察到ClO(2)的一级生成速率取决于HOBr浓度。确定对ClO(2)(-),Cl(-),H(+)和缓冲液浓度的速率依赖性。在BrCl / BrO(2)(-)反应中,BrCl与过量的HOBr处于预平衡状态,因此会跟踪由于BrO(2)(-)引起的吸光度损失。对于ClCl / BrO(2)(-)反应,确定了对Cl(-),HOBr,H(+)和HPO(4)(2)(-)浓度的依赖性。在建议的机制中,BrCl / ClO(2)(-)和BrCl / BrO(2)(-)反应通过Br(+)转移进行,分别形成稳态水平的BrOClO和BrOBrO。BrCl / ClO(2)(-)反应[k(Cl)(2)]的速率常数为5

    Vibrational frequencies of gaseous Br2O and OBrO were observed using the Fourier transform infrared spectrometer. For the first time, bands at 629.0 cm−1 (ν3) and 532.9 cm−1 (ν1) were recorded for both Br–O asymmetric and symmetric stretching vibrations of gaseous Br2O. Two fundamental vibrations were observed at and for the O radical. In addition, two new peaks at 2333 cm−1 and 668 cm−1 were observed

    The BrO radical, prepared by the Br+O3 reaction, has been investigated by ultraviolet photoelectron spectroscopy. Two vibrationally resolved bands were observed corresponding to the ionizations BrO+(X3Σ−)←BrO(X) and BrO+(a 1Δ)←BrO(X). These assignments are supported by the results of complete active space self-consistent field/multireference configuration interaction (CASSCF/MRCI) calculations
