Despite their beauty and popularity, fireworks also pose certain risks and negative impacts on the environment and health. 尽管烟花美丽而受欢迎，但它们也对环境和健康带来一定的风险和负面影响。
One of the main concerns with fireworks is their contribution to air and noise pollution, especially in densely populated urban areas. 烟花的主要问题之一是它们对空气和噪音污染的贡献，尤其是在人口密集的城市地区。
The chemicals and heavy metals used in fireworks, such as sulfur, potassium nitrate, and aluminum, can release harmful fumes and particles when ignited. 烟花中使用的化学物质和重金属，如硫磺、硝酸钾和铝，当点燃时会释放有害的烟雾和颗粒。
These pollutants can affect air quality, leading to respiratory issues and exacerbating conditions such as asthma and bronchitis. 这些污染物会影响空气质量，导致呼吸道问题，并加剧哮喘和支气管炎等疾病。
