Applications involving maritime surveillance, border protection, homeland security, and command and control typically use airborne surveillance to detect various types of targets in order to determine shapes, temperatures, or chemical nature.
Since it was first settled in 1841, California's San Gabriel Valley has hosted a wide variety of industries. However, industrial development has left a significant portion of the Valley’s groundwater contaminated with various organic contaminants, including N-nitrosodimethylamine (NDMA) and 1,4-dioxane.
Particulate matter (PM) in flue gas can exhibit highly variable and dynamic characteristics that are dependent on plant fuels, processes, and control parameters. The main characteristics of interest are mass concentration, particle size, defined by the aerodynamic diameter of the particle, and chemical composition, which relates to the eventual toxicity of the particulate matter in the ambient air outside the stack.
