Evaluating Particulate Emissions from Jet Engines ...

The results of this study suggest that the range of size of particulateemissions from some jet Engines clusters below m and that theemissions contain heavy metals. Therefore, jet exhaust particulates (JEPs) have the potential to adversely affect both the environment andhuman health. Little is known about the Particulate component of jetengine Emissions . Baseline physical and chemical data on JEPs wereobtained to evaluate their potential effects on the environment. Parti-cles collected from the exhaust stream of two types of jet Engines wereexamined using scanning electron microscopy. Analysis indicated that100 percent of the particles collected were below m in size. Parti-cles in this size range can penetrate to the alveoli of human analyses of jet engine exhaust were conducted in an attemptto identify chemical fingerprints that would distinguish aviation emis-sions in the environment from other anthropogenic Emissions . Certainheavy metals, especially vanadium, were found in jet exhaust and maybe useful chemical fingerprints.

The results of this study suggest that the range of size of particulate emissions from some jet engines clusters below 1.5 µm and that the emissions contain heavy metals.
