Abstract

Considering the increase in environmental pollutants and their direct impact on human health, the necessity for research on pollution reduction factors has increased. Meanwhile, gasoline vehicles are considered one of the most important polluting factors in the country. In this research, the environmental effects of 9,000 cars, which were produced between 2007 and 2018, have been investigated. For this purpose, three cars, which include Pride, Peugeot Pars and Thunder 90, have been considered and 3,000 cars have been selected from each of them. Therefore, at the beginning, the study cars are divided into four-year categories based on the year of their production. Then the environmental pollutants HC and CO, which are very dangerous for human health, were investigated in the mentioned time periods and the effect of the car's life on the amount of these pollutants was examined. In the next step, statistical analysis was done using Pearson's correlation test in SPSS software. According to the investigations, the year of car production has a direct effect on the production of studied pollutants. By examining CO pollutant gas in the minimum range of its production, the number of cars with production years 2015 to 2018 has increased by 65% compared to cars with production years 2007 to 2010. This parameter has been evaluated at 27% in similar conditions for HC pollutant gas. In addition, according to the statistical analysis, the relationship between the life of the car and the pollutants produced by it has been evaluated as significant in all cases.
