二氧化氮健康影响基准资料总结二氧化氮(NO_2)远不如二氧化硫易溶于水,故较易进入气道深部,首先影响呼吸道和肺组织的粘膜,并从肺通过血液到达和影响其他器官。动物短期暴露于NO_2的健康影响,主要是在高浓度下研究的。长期暴露于NO_2600μg/m~3时,出现组织变化。长期暴露于1500μg/m~3,肺功能方面出现呼吸率增高。长 Nitric Oxide Health Effects Benchmarking Information Summary Nitrogen dioxide (SO2) is far less likely to be soluble in water than SO2, so it is easier to enter the deep airway, affecting the mucous membranes of the respiratory tract and lung tissue first and reaching and affecting other organs through the bloodstream from the lungs. The short-term exposure of animals to the health effects of NO 2 is mainly studied at high concentrations. Long-term exposure to NO_2600μg / m ~ 3, the tissue changes. Long-term exposure to 1500μg / m ~ 3, respiration rate increased pulmonary function appeared. long
