A coating material that is applied to a surface for absorbing a toxic chemical and that is removable from the surface by the use of mechanical force is disclosed. The coating material comprises one or more polymer coatings, one or more purified enzymes immobilized or entrapped in the polymer coating for protecting a surface from contamination by one or more toxic chemicals, one or more reporter indicators that are responsive to changes in pH in the presence of the toxic chemical for detecting and disclosing the location of said toxic chemical, and one or more buffers for establishing and/or maintaining the pH of the coating ranging from 5 to 10. Preferably, the reporter indicator is one or more pH-sensitive dyes or dye blends that change colors in the presence of the toxic chemical. A method for absorbing, detoxifying, detecting and disclosing of a toxic chemical is provided. |
