ABSTRACT
Gas, odor, and aerosol emission all share the atmosphere as a common transport system. In the absence of atmospheric oxygen, intermediate breakdown products of organic matter and synthesized intermediate compounds accumulate, in addition, notably methane, carbon monoxide, hydrogen, hydrogen sulfide, and numerous volatile odorous organics. A report by Landreth and Rogers contains a list of chemical methods, some of which relate to chemical combination and some to gas control. Odor control techniques center around well-known reactions. The most effective solution to odor problems is to change the waste-treatment design or source environment from anaerobic to aerobic. Aerosols also may originate from large open impoundments and vary in emission depending on wind intensities. The greater the wind intensity, the greater the aerosol emission. Soil filter-scrubbers are designed to remove air pollutants of odor, gases, aerosols, and particulates. They are more in use in European disposal designs than in the U.S.
