Chemical Assays

Definition

Chemical assays are analytical procedures used to determine the presence, concentration, or activity of a specific substance within a sample. These assays are essential in bioremediation, especially in evaluating the effectiveness of microbial communities and their metabolic processes in breaking down pollutants like oil spills.

5 Must Know Facts For Your Next Test

1. Chemical assays can provide quantitative data on pollutant concentrations, which is crucial for assessing the progress of bioremediation efforts.
2. Different types of chemical assays include colorimetric assays, spectrophotometric assays, and enzymatic assays, each suitable for specific substances and conditions.
