Emissions from Street Vendor Cooking Devices (Charcoal Grilling)

摘要

The report discusses a joint U.S./Mexican program to establish a reliable211u001eemissions inventory for street vendor cooking devices (charcoal grilling), a 211u001esignificant source of air pollutants in the Mexicali-Imperial Valley area of 211u001eMexico. Emissions from these devices, prevalent in the streets of Mexicali, 211u001eMexico, were investigated experimentally by measuring levels of particulate 211u001ematter, particle size distributions, volatile and semivolatile organic compounds, 211u001ealdehydes, and oxides of nitrogen and sulfur, emitted when meat is cooked on a 211u001egrill over a charcoal fire. To investigate the emission rate, both beef and 211u001echicken were tested. Furthermore, both meats were marinated with a mixture 211u001esimilar to that used by the street vendors. Some tests were conducted with non-211u001emarinated beef for comparison. Two blank runs were performed sampling charcoal 211u001efires without meat. Finally, a simple control device, normally used in an exhaust 211u001efan to trap grease over a kitchen stove, was evaluated for its effectiveness in 211u001ereducing emissions.
