The harvest also contaminates

The fact of working an hour with the grass cutter is the same as a car trip of 150 kilometers. This is, at least, the result of the study conducted by a group of Swedish researchers. But these machines are not the only ones that contaminate, since mechanical saws and other tools with motor have the same problem.
This type of machines have a gasoline powered engine and, according to Roger Westerholm of the University of Stockholm, when burning gasoline polycyclic aromatic hydrocarbons are formed. Some of these substances are very dangerous for health, as they cause cancer. To reduce emissions and solve the problem, it is proposed to place a catalyst similar to that of cars.
