Carbon monoxide of carbon dioxide by electromagnetic radiation of wavelengths shorter than 169 nm. Due to its long lifetime in the mid-troposphere, carbon monoxide is also used as tracer of transport for pollutant plumes. Carbon monoxide is a temporary atmospheric pollutant in some urban areas, chiefly from the exhaust of internal combustion engines (including vehicles, portable and back-up generators, lawn mowers, power washers, etc.), but also from incomplete combustion of various other fuels (including wood, coal, charcoal, oil, paraffin, propane, natural gas, and trash). Large CO pollution events can be observed from space over cities. Carbon monoxide is, along with aldehydes, part
Lawn mower mowers have a tunnel that extends from the side discharge to the bag. Hi-vac is also the type of grass collection used on some riding lawn mowers and lawn tractors and is suitable for use in dry conditions but less suitable for long wet lush grass as they often clog up. Mulching and bagging mowers are not well suited to long grass or thick weeds. In some ride-on mowers, the cut grass is dropped onto the ground and then collected by a set of rotating bristles, allowing even long, wet grass to be collected. Rotary mowers with internal combustion engines
