Background and purpose: Vegetables are among the valuable foods. However, in addition to essential elements, they may contain toxins in excess of permissible concentrations, which has raised many concerns about the quality and safety of these products and human health. Therefore, the present study was conducted to investigate the effect of atmospheric pollutants of carbon dioxide, gasoline and acid rain on the resistance of basil and parsley.Materials and Methods: This factorial study was performed based on a completely randomized design with 3 replications and 54 treatments . In this study, CO2 with three concentrations of 0, 1000 and, 1800 ppm, gasoline with three conditions without adding gasoline, with ordinary gasoline and with the addition of super gasoline, and acidic solution at two levels of pH 4 and 6 were studied. It should be noted that distilled water with pH = 7 was selected as a control treatment.Results: The results showed that the concentration of 1000 ppm carbon dioxide increased plant yield by 178.63%, while its concentration up to 1800 ppm, led to the destruction of the plant in two days. It was also found that super gasoline due to the high-octane number and supplements in it has a less polluting effect (5.7%) on the plant than regular gasoline. In addition, no significant difference was observed between different concentrations of acidic solution on plant resistance. In this experiment, parsley showed more resistance to contaminants than basil.Conclusion: carbon dioxide than other pollutants and also its key role in global warming, we need effective management to promote public health and control the production sources of this gas in the atmosphere.
