Gaseous wastes from soils

Containment and Control Options for Gaseous Wastes from Soils... 

For the gaseous contaminants the release mechanism from the soil is generally based in the principles of diffusion across a porous medium. Basic diffusion equations are used for estimating the theoretical values of the gaseous flux from the waste material. The generic diffusion equation can be represented by a one-dimensional steady-state equation ... 

Hazardous wastes range from synthetic organic chemicals to heavy or toxic metals, to inorganic sludges, to solvents, to dilute aqueous streams. They may be solid, liquid, or gaseous they may be pure materials, complex mixtures, residues and effluents from operations, discarded products, or contaminated containers or soil. Most liazardous wastes are managed on the site where they are generated, mere so in some btates and... 

Respirable particulate or gaseous forms of lead may be inhaled. Sources include cigarette smoke vehicle exhaust emissions from municipal waste incinerators, iron and steel plants, smelting and refining operations, lead acid battery manufacturing facilities, and sandblasting and burning of surfaces coated with lead paint. Particulate air emissions may eventually deposit and contaminate the soil.
