PUR Foams as Sources of Emissions in the Vehicle Interior - Evaluation of the Present Situation and Modes of Reduction

The reduction of organic emissions from materials within the vehicle interior has noticeably contributed to the comfort of automobile customers over a period of approximately 20 years. Classes of materials that have been improved in this manner are soft PVC films, SMC, leather, textiles and, to cite a recent example, polyester wood coatings. PUR foams represent a class of materials that are widely used due to their outstanding and widely variable properties. However, they are still a source of undesirably high emissions as illustrated in a screening analysis by DaimlerChrysler.

Characterisation of gas phase organic emissions from hot cooking oil in commercial kitchens.

A large quantity of oily fumes is generated in fast food and Chinese restaurants from cooking oil kept at a high temperature in the kitchens. If these oily fumes are not properly abated, they can be a major source of organic emissions in some dense urban areas with a lot of restaurants such as found in Hong Kong. In the present study, the most commonly used cooking oil, peanut oil, was kept at 260°C in an environment typical of a commercial kitchen that consisted of a two-burner stir-frying cooking range, a single-tank electric fryer, a baffle-type grease extractor and an exhaust duct.
