Fireworks spark controversy

While being an age-old tradition, fireworks are also big business in China. But as the beginning of the year has seen high levels of pollution, many are beginning to raise questions on the health and environmental costs of using fireworks.

This is the sound that ushers in the Chinese New Year.

"The feelings of the new year are very important, to have to feel you have to have firecrackers."

Every year, people all across the country shell a lot of money to set off fireworks.

"We have a daily turnover of 5 to 6 thousand yuan. And as we get closer to the end of the year, demand increases."

But now, this ancient tradition is sparking controversy.

The noise, pollution and garbage it leaves behind, all seem to go against the concept for a modern city.

Qiu Jian, Zhenjiang Environment Monitoring Center, said:"The main ingredients of firecrackers can pollute the air, such as sulphur dioxides, carbon monoxides, nitrogen oxides and small particles like PM10 and PM2.5. "

He says setting off firecrackers during smoggy weather can further deteriorate air quality.

Every year during spring festival, hospitals are packed with patients with respiratory problems. And firecrackers are the main culprits.

Xia Wu, assoc. chief physican of Zhenjiang No.4 Hospital, Respiratory Dep't, said:"Those who watch fireworks can wear a mask. And it's a good idea to watch fireworks at home. Also you want to set off firecrackers in the open field. it's safe and good for the respiratory system, because the smoke goes away quickly."

Despite all the side effects, firecrackers still remain a must-have to welcome the coming year. And the debate over whether ancient traditions supersede modern realities, is still an ongoing debate.
