Title StatementChemical analysis of fireworks and firecracker emissions during the 2002 New Year's Day celebration
Summary, Etc.In the Philippines, the New Year is always celebrated with the use of fireworks. The tradition comes from the Chinese belief that loud explosions and bright and colorful sparks will drive away all the bad luck from the previous year. The New Year of 2002 was relatively peaceful compared to the previous years. Before, many have been injured and an alarming increase of casualties forced the government to control the use of fireworks. The 2002 New Year's Day celebration had reportedly less injuries when strong explosives were banned. Along the spectacular aerial light and sound displays are thick smoke emitted by the explosions. These are by-products produced when the explosive mixture, gunpowder (mixture of charcoal, sulfur and potassium nitrate) burns by itself by creating its own source of oxygen when heated rather than using oxygen in the atmosphere. The mixture may also include metals such as aluminum and magnesium that propels rockets and sprays showers of sparks in fountains and Catherine wheels, and/or salts that make fireworks produce colored flames such as sodium salts (yellow), copper salts (blue), barium salts (green) and strontium salts (red). Afterwards, these metals blend in the atmosphere either in pure or compound form. They stay in the atmosphere as particulate matter that may cause harmful effects on health
