A technique for collecting relatively dry fungi by â€œstickingâ€ or â€œliftingâ€ the suspected fungus with the adhesive side of clear (not frosted) tape. This can later be transferred to a microscope slide for direct analysis.
The classification and grouping of organisms (living or post
Toxicity Characteristic Leaching Procedure used to determine the federal Resources Conservation Recovery Act (RCRA) lead hazardous waste limits. If the results equal or exceed 5 mg/L the waste is deemed to be hazardous.
Hypha involved in conversion to spore formation.
|Total Cell Count||
Cell count that includes both viable and non viable cells.
The (measured) ability of a substance, organism to be poisonous.
Toxin producing. Ex: â€œFemale Blackwidows are toxigenic.â€
A trade name for asbestos cement wallboard or pipe.
|Transmission Electron Microscopy (TEM)||
State-of-the-art analytical method for air and bulk sample analysis. Uses high magnification (typically 15,000x) to identify asbestos fibers. May utilize Energy Dispersive Spectroscopy (EDS) and/or Selected Area Electron Diffraction (SAED) to confirm asbestos and to identify the type of asbestos present. Recommended for final clearance air samples and for bulk analysis of samples with difficult-to-analyze matrices (e.g., plaster, vinyl tile). Provides the most definitive analysis of asbestos currently available.
Total Threshold Limit Concentration used in the State of California in conjunction with STLC to determine lead hazardous waste limits. If the results are equal to or exceeds 1000 mg/kg, the waste is deemed to be hazardous.
