Question

Masks, a simple protective tool, have been used by people for a long time. They can not only prevent epidemics, but also protect us from other harmful things, such as smog (霧霾) and chemicals. When was the protective mask first invented and how did it develop? Let's take a look.

1st century At this time, lots of people in the Roman Empire worked underground in mines (礦井). Many died of lung (肺部) diseases caused by dust. Pliny the Elder (23-79), a Roman philosopher, used animal bladders (膀胱) to protect miners from the dust. This was the first recorded use of protective masks.

16thcentury Italian artist and inventor Leonardo da Vinci (1452-1519) advised people to wear a woven (紡織的) cloth dipped in water over their faces to protect against harmful chemicals.

19th century In 1848, American Lewis Hassley became the first person to patent (注冊專利) a protective mask for miners. In 1897, Polish-Austrian doctor Johann von Mikulicz Radecki designed a simple mask with one layer of gauze (紗布). He advised medical workers to wear it to prevent infection. This was the first use of a surgical (外科的) mask.

20th Century In 1910, the pneumonic plague (肺鼠疫) broke out in Northeast China. Chinese doctor Wu Liande designed a face mask called 'Wu's mask'. It was made of two layers of gauze. The mask was praised by experts around the world because it could be produced easily and cheaply.

Today With several outbreaks of flu and the air pollution in recent years, masks have continued to develop. For example, in 2012, when China suffered from smog, mask models such as N95 and KN95 became popular. They can filter out (過濾掉) fine particulate matter (微粒物). China is now the world's largest mask producer, making out half of the world's masks.
