Rapid and unchecked industrialization and the combustion of fossil fuels have engendered a state of fear in urban settlements. Smog is a visible form of air pollution that arises due to the over-emissions of some primary pollutants like volatile organic compounds (VOCs), hydrocarbons, SO, NO, and NO which further react in the atmosphere and give rise to toxic and carcinogenic secondary smog components. Smog reduces the visibility on roads and results in road accidents and cancellation of flights. Uptake of primary and secondary pollutants of smog is responsible for several deleterious diseases of which respiratory disorders, cardiovascular dysfunction, neurological disorders, and cancer are discussed here. Children and pregnant women are more prone to the hazards of smog. The worsening menace of smog on one hand and occurrence of pandemic i.e., COVID-19 on the other may increase the mortality rate. But the implementation of lockdown during pandemics has favored the atmosphere in some ways, which will be highlighted in the article. On the whole, the focus of this article will be on the dubious relationship between smog and coronavirus.
快速无节制的工业化和化石燃料的燃烧在城市聚居区产生了一种恐惧状态。烟雾是空气污染的一种可见形式,它是由于一些主要污染物(如挥发性有机化合物 (VOCs)、碳氢化合物、SO、NO 和 NO)的过度排放而产生的,这些污染物在大气中进一步反应,产生有毒和致癌的二次烟雾成分。烟雾降低了道路的能见度,导致交通事故和航班取消。烟雾中的一次和二次污染物的吸入会导致许多有害疾病,这里讨论了呼吸道疾病、心血管功能障碍、神经紊乱和癌症。儿童和孕妇更容易受到烟雾的危害。一方面,烟雾的威胁日益严重,另一方面,大流行病(即 COVID-19)的发生可能会导致死亡率上升。但是,在大流行期间实施封锁在某些方面有利于大气,这将在文章中强调。总的来说,本文的重点将放在烟雾和冠状病毒之间可疑的关系上。
