Research Excerpts

Overview

Monochloramine (NH(2)Cl) is a potent, thiol-directed oxidant capable of oxidizing thiol (S-H) residues in a wide variety of proteins. Chloramine T is a known sensitising agent in the occupational environment of health care workers.

Effects

Monochloramine has been used to provide a disinfecting residual in water distribution systems where it is difficult to maintain an adequate free-chlorine residual or where disinfection by-product formation is of concern. Monochloramines has been suggested as an alternative disinfectant to chlorine to reduce levels of trihalomethanes in treated drinking water.

Actions

Monochloramine colitis was amenable to pharmacological treatment with sulphasalazine or prednisolone, suggesting that it may be used as an experimental model of inflammatory bowel disease. Chloramines inhibit platelet function in PRP: about 1 mM CT suppresses 50% of the aggregatory capacity of thrombocytes.

Dosage Studied

Pilot-scale tests revealed that much lower dosing rate was required to maintain similar total chlorine residual. Monochloramine was less effective at typical drinking water dosage concentrations of 3 mg/L. Chloramine dosage and pH are essential influencing factors.
