The Stocks form allows users to add, edit or view information concerning the Stocks (stored liquids) and Pure Chemicals in the database. A Stock is a material that is entered into the database and is available for selection as the liquid stored in a Tank. A Pure Chemical is a compound that can be a component (constituent) of a Stock, available for estimating and reporting as a separate (speciated) air pollutant.
For each Stock, you can specify which Pure Chemical components are to be included for speciation. A drop-down list at the top of the form allows you to select from the Stocks and Composition, Stock Site Applicability, Flash Gases, Flash Gas Site Applicability, and Pure Chemicals forms.
