Setting off fireworks to celebrate festivals and happy occasions has been a tradition for Chinese people. The loud booms as well as the striking spectacles displayed by the fireworks add to the jubilance of the day. However, the most beautiful aspects of fireworks cannot compensate for the problems they generate. Whether to ban the fireworks has always been a controversial topic among people. As the Air Pollution Index in Beijing becomes incredibly high this winter, a new discussion on the necessity of firework banning policy has been raised. To ban (not simply regulate) the use of firecrackers is the right thing to do, since the positive effects of banning outweigh its drawbacks. To be more specifically, both rockets and fireworks should be banned in all areas (including rural areas). No one is allowed to sell or buy firework, even those who have been trained to set up large organized displays.
The tradition of burning bamboo to create loud noises as part of Chinese New Year celebrations goes far back in history. Scholars from the Western Han (206BC-AD8) through the Southern Song (1127-1279) dynasties all recounted a popular belief that the noises could expel or scare away a mountain demon Nian to ensure a happy, peaceful new year. Fireworks became popular in Qing Dynasty. They are propelled into the sky to create large, multicolored works as visual arts for celebration. Other countries all over the world also use firecrackers and fireworks to celebrate their festivals.
For safety reasons, most Chinese cities banned firecrackers and fireworks in the year of 1990. From 1987 to 1993, during which time the explosions of firecrackers injured 2462 citizens in Beijing, the dangerous aspect of firecrackers has been taken into concern...

In conclusion, it is clear that situations like this could easily be prevented with a few vitals steps. The first step in the line of prevention is restriction of flammable materials in nightclubs and other buildings, especially in enclosed spaces. Second is the installation of fire prevention systems—fire extinguishers, sprinkler systems and fire alarms with early notification to the local fire authorities. Also, the prevention of using dangerous pyrotechnics in enclosed spaces is imperative. Finally, the need for sufficient exits is vital to the safety of the people in any building, especially a crowed nightclub.
Since man’s first experiences with fire we have longed to control it and we wished to will it to do our bidding. For very long we failed mostly, and we still do sometimes, but with the trials and experiments we have done and died doing, we succeed now, mostly. The first formula that is still written down of an “explosive or pyrotechnic composition” are the three examples of gunpowder in the 1044A.D. Chinese military guide Wujing Zongyao which showed a few uses of this powder they had experimented with for near a hundred years. The most used formula from it was approximately 50% KNO3, also known as Saltpeter in those times, and formally called Potassium nitrate today, ~25% S, Sulfur, and ~25% carbonaceous matter (mostly charcoal and compounds mixed with impure sulfur); the other formulas move the percentages for the KNO3 around 10-15%, S 5-10%, and carbonaceous 7-20% to adjust burn rates and usefulness in certain situations. The likely only reason gunpowder was ever invented was the Chinese’s wish to live long, and their many mixtures of elixirs, which was what gunpowder was intended to be used as (more-pyrotechnics.com). “Within 200 years China had several crude weapons, mostly huge iron or alternative metal barrels and maybe a wooden grip but with no aiming attachment. They also had very many types of fireworks using no telling how many formulae for devices ranging in size, color, and purpose. People in Europe hear of this powder and its power, and then slowly find out more“(more-pyrotechnics.com). Then by 300 years they had better arsenals, larger cannons that actually worked well, and better, lighter barrels. The Indians and Islamic nations have made use of this by now, neither surpassing China’s previous ones nor Europe’s futu...
Disney world, the world’s beloved theme park, putting a smile on every child’s face and pulling them into the magical world of Disney fairies and princesses, making people awestruck by the fantastic fireworks show every night, but has anyone wondered how much pollution is caused by these fireworks? I am sure none of us think about pollution when standing beneath the firecrackers bursting in the night sky but the growing problem of air pollution is no stranger to all of us. We keep hearing and reading reports about the depletion of ozone layer and the never-ending problem of Global warming. So why do we still allow these big companies like Disney to have fireworks show every night all year round? Although the fireworks
Every year, America celebrates many holidays with fireworks. One of the most popular selections is a Roman Candle. If you want to try to make this at home, common pyrotechnics stores have all the supplies you would need. Just think of the “oohhs” and “ahhhhs” when you light off your homemade fireworks at home.
The staggering number of fatalities can be attributed mainly to the proximity of the pyrotechnics to flammable sound insulating foam, overcrowding of the facility, and the lack of sprinkler system (Graybill, 2003, para. 1). It is tragic to have any loss of life; however, it is more tragic when lives are lost carelessly.
He grew up in a time and setting where cannon blasts and fireworks where common occurrences. These experiences have been inspiration for some of his gunpowder drawings and explosion events. During his late teens and early twenties, Guo-Qiang acted in two films, The Spring and Fall of a Small Town and Real Kung Fu of Shaolin. His early work was inspired by traditional Chinese culture. His artwork consists of a variety of symbols, narratives, fengshui, traditions, shanshui paintings, flora and fauna, portraiture, Chinese medicine and fireworks. He draws on the Maoist/Socialist concepts for content in many of his pieces. Cai is among the first artist to contribute to the discussion of Chinese art and is considered very important to the history of Chinese contemporary art. As a young student, his stick figure or abstract patterns in oil and gunpowder gave him a place in the 85 New Wave movement, but he moved to Japan in 1986 just as the movement was gaining speed. His initial gunpowder drawings were meant to confront China’s controlled artistic traditions. Eventually leading him to experiment with explosives on a larger scale and resulted in the development of his signature “explosion
While traveling the globe, Marco Polo, fascinated by this black powder, brought it back to the West were it soon caught on. In Rome, King Charles V used fireworks to celebrate a victory. The fireworks were developed and made by his “fire workers” who made leaps and bounds with the projectiles and rocket shape of the fireworks. These elaborate demonstrations of fire soon spread through Europe and pleased many spectators of the King and Queens Court.
Through adventurous explorers, the knowledge of making fireworks spread west, through Arabia in the seventh century. The Arabs called the rockets Chinese arrows. The Mongols are credited with taking Chinese rockets and gunpowder to Europe around 1241. The first record of their use in Europe are around 1258. Until the 19th century, fireworks lacked a major aesthetically essential characteristic: color. Pyrotechnicians began to use a combination of potassium chlorate and various metallic salts to make brilliant colors. The salts of these metals produce the different colors: strontium burns red; copper makes blue; barium glows green; and sodium, yellow. Magnesium, aluminum, and titanium were found to give off white sparkles or a flash.
In modern times there are over 14,000 fireworks displays every year. The largest display is the Macy’s Fourth of July Spectacular were over 75,000 lbs of fireworks are set off in a half hour show. Last year it was witnessed by over 2 million spectators. President Adams would be so proud.
"Fireworks were first invented in China more than 2,000 years ago, and they continue to delight individuals today. To this day, many believe the use of fireworks scares off ghosts and evil spirits. While most associate these illuminations with New Year's Eve or the Fourth of July, they make a great addition to any wedding reception," Julian Garner, spokesperson for Fireworks International, announces.
Factories and transportation depend on huge amounts of fuel--billions of tons of coal and oil are consumed around the world every year. When these fuels burn they introduce smoke and other, less visible, by-products into the atmosphere.
...operties. Char is weak light absorption with a strong spectral dependence while Soot is strong light absorption characteristics with little spectral dependence (Han et al., 2010). By the way, Particle matter (PM) was associated with cardiovascular mortality and morbidity. Spontaneous Hypertensive Rate was the effect of single intrataracheal of PM2.5, it increased the parasympathetic nervous activity and decreased the heart rate (Ryoko, 2008). PM consists of a complex mixture of solid and liquid particles of organic matter, mineral dust, secondary inorganic aerosols and trace metals, as well as water and unspecified compounds (Katarzyna et al., 2011). In order to avoid the impact negative on public health, climate change and keep an economic growth with acceptable environmental loads, the investigations of emission sources of air pollutants are essentially important.
This paper examines the factors that led to the climate change and environmental threat particularly air pollution and also identifies the roles of the Chinese government in resolving the environmental crisis. Every single day, globalization is keeping moving forward and makes human unpredictable what will happen in the future include human security. As in the case of climate change, as the same thing occurred to human security threats because they related each other. The rapid in industrialization, the gradually growth of economics and the globalization in China contributing to the factors of environmental crisis and climate change to their society. Consequently, these transformations gave the negative impact on human security which is in economically, domestically, agriculturally and the most important thing is the health of human. Therefore, those issues will be challenges to the policy makers of the Chinese government to identify the suitable policy to implement and also find a way to confront these issues as a responds to the resolving the environmental crisis and climate change.
A main cause in the recent studies of global warming is the usage or aerosols. Aerosols are a substance enclosed under pressure and able to be released as a fine spray, typically by means of propellant gas. An aerosol can range from hairspray all the way to dust particles in the air. The new worries that are starting to show prominence in society today are the increase in carbon dioxide from t...
