Millions of fireworks are set off around the world on special occasions such as New Year. Although this is a tradition that is both colorful and impressive, it results in all kinds of environmental problems. Air pollution, plastic residues, metal deposits on land and in water are just some of the consequences of New Year celebrations, yet these are often forgotten in order to maintain the celebratory tradition of fireworks.
Many of the metals released by fireworks are environmentally hazardous or toxic at high concentrations. Arsenic, for example, is highly toxic to several organisms, while aluminum can attach to the gills of fish and suffocate them. The metals pose a risk of health problems for several life forms. In concentrated amounts they can even result in death.
