最近的研究已表明,居住在臭氧少于百万分之0.08的地方能影响儿童的肺功能,因此限制儿童在户外活动就必须慎重考虑了,因为污染会造成严重的呼吸器官疾病,包括呼吸急促和呼吸困难。臭氧是一种由3个氧原子结合而成的气体。在地面上,多数臭氧的形成是污染物质对太阳光影响起反应,是发生了化学变化而造成的,这些污染物质主要 Recent studies have shown that residing in less than 0.08 parts per million of ozone can affect children’s lung function and therefore restricting children’s outdoor activities must be carefully considered because contamination can cause serious respiratory diseases including shortness of breath And breathing difficulties. Ozone is a gas composed of three oxygen atoms. Most of the ozone formation on the ground is caused by the chemical changes that pollutants react to the effects of sunlight. These pollutants are mainly
