Investigation of pollution output in felling by chainsaw

Chainsaw is an important instrument in felling. The chainsaws that use in forest are working by gas and all of them have tow-stroke cycle engine. Gas is a combined cycle hydrocarbon with a different ratio in material that burning them is polluting the air. This study was done in lower height forests of Mazandaran Wood and Paper Industries Co. (MWPI). The aim was study about amount of gas polluting the air from each cubic meter of wood production by chain saw in felling activities. Results show that the average consumption of gas for felling is 81.7 cc/m3 wood and the amount of scattered polluter were: Carbon Oxide 46.7 gr, Nitric Oxide 1.2 gr, Hydrocarbon 5.3 gr, Plumb 0.03 gr, Benzoapyrene 0.0001 gr, and Dust 0.007 gr. The lowest amount of scattered Co2 was 1.2 gr and the most amounts were 14.8 gr for felling each cubic meter of wood.
