Pollutant describes any irritant or contaminant—substances like smoke, vapors, soot, fumes, acids, alkalis, chemicals, and waste. This term is used in pollution-related coverage to capture the broad range of harmful substances that can cause environmental or property damage. Risk refers to the likelihood of loss, not the contaminant itself; products denote manufactured goods, not a contaminant; special damages are a damages category in tort law. So pollutant is the best fit for identifying irritants or contaminants.
