Environmental effects of fireworks with special consideration of plastic emissions

In Germany, about 133 million Euro are spent annually for New Yearâ€™s Eve fireworks, which result in 38,000 to 49,000 Mg of total firework mass. By a com-bination of desk research with official fireworks approval statistics, a customer survey, dismantling experiments with fireworks debris and with packaging characterisation, the total nationwide polymer emission was estimated to be 3,088 Mg. Out of this total mass, a projected polymer debris mass of 534 Mg was identified, and about 270 Mg of polymer packaging material. The remaining 2283 Mg of polymer mass are parts that eventually may remain at the launching site.
Statistical modeling approaches for urban traffic noise

Simulation of urban traffic noise along with a statistical model of traffic noise for the road network in the city center is presented in this paper. The road network of the central park of Patras â€“Greece was used as the study area. The modelâ€™s parameters include traffic volume, with every type of vehicle, and the average speed of vehicles.
