Detection of Free Charges from Motor-Car Exhaust Gases

Uptake of inhaled lead from motor exhaust.

To assess the contribution of lead in motor exhaust to the total uptake of lead it is necessary to know the amount deposited in the lungs, the uptake thence to blood and other tissues, and the rate of excretion from the body. There are reports of experiments in which volunteers have inhaled aerosols of lead oxide or sesquioxide (Kehoe, 1961; Hursh et al., 1969; Booker et al., 1969; Cole and Lyn...

Emission controls on cars and accidental deaths from car exhaust.

Options for Abating Greenhouse Gases from Exhaust Streams

This report examines different alternatives for replacing, treating, and recycling greenhouse gases. It is concluded that treatment (abatement) is the only viable short-term option. Three options for abatement that were tested for use in semiconductor facilities are reviewed, and their performance and costs compared. This study shows that effective abatement options are available to the photovo...

Non-thermal Plasma Treatment of Automotive Exhaust Gases

Treatment of NOx in diesel engine exhaust represents a big opportunity for the environmental application of low-temperature plasmas. In this paper NOx conversion to N2 was investigated by Plasma/Catalyst System Catalytic activity was enhanced by the assistance of plasma ,and the plasma/Catalyst system showed higher NOx conversion. It is shown that the plasma by itself cannot chemically reduce N...

Studies of MISiC-FET sensors for car exhaust gas monitoring

The increasing size of the car fleet makes it important to find ways of lowering the amounts of pollutants from each individual diesel or gasoline engine to almost zero levels. The pollutants from these engines predominantly originate from emissions at cold start, in the case when gasoline is utilized, and high NOx emissions and particulates from diesel engines. The cold start emissions from ga...
