Researchers compared the particulate matter in the exhaust fumes from a modern car engine, fuelled with low-sulphur diesel, and in cigarette smoke. Three smouldering cigarettes produced a 10-fold increase in air particles compared to those produced by the idling vehicle. “I was very surprised. We didn’t expect to find such a big difference in the particulate matter produced,” says Giovanni Invernizzi from the Tobacco Control Unit of Italy’s National Cancer Institute in Milan, who led the study. Ivan Vince, an air pollution expert from Ask Consultants in London, UK, says the findings are reasonable. He notes that cigarettes give off a lot more respirable particulates than the new generation of low-sulphur diesels, which help cut particulate emissions.Smouldering cigarettes Invernizzi and colleagues conducted their controlled experiment in a private garage in the small Alpine town of Chiavenna, which enjoys a particularly low level of air pollution. |

The term cigarette, as commonly used, refers to a tobacco cigarette but can apply to similar devices containing other herbs, such as cloves or cannabis. A cigarette is distinguished from a cigar by its smaller size, use of processed leaf, and paper wrapping, which is normally white, though other colors are occasionally available. Cigars are typically composed entirely of whole-leaf tobacco. |
