- Abstract
In the exhaust of "apartment" heating appliances, as a result of natural gas combustion, in addition to carbon and nitric oxydes or sulphur derivates, there is also particulate matter (PM) containing polyaromatic hydrocarbons and derivates (of which benzopyren is the most notorious carcinogenic compound). The aims of our study were to identify PM in the exhaust (emission) of "apartment" heating appliances installed in apartments in Cluj-Napoca, and to study their aspect and sizes by scanning electron microscopy. The scanning electron microscopic aspects were studied with a Jeol JSM 25S electron microscope, and the PM were sized on the digital images, proving the presence of PM in the exhaust of "apartment" heating appliances. PM size distribution confirms that PM susceptible of being inhaled by breathing: PM 2.5 (diameter below 2.5 μm) and PM 10 (diameter below 10 μm) abound in the exhaust (emission) of "apartment" heating appliances.
