Author Description

N-Nitrosodimethylamine (NDMA) is the simplest dialkylnitrosamine, with a molecular formula of C2H6N2O and a relative molecular mass of 74.08. It is no longer used industrially or commercially in Canada or the USA but continues to be released as a by-product and contaminant from various industries and from municipal wastewater treatment plants.<br> <br> In this volume are assessed the risks to human health and the environment of this chemical. Based upon laboratory studies in which tumours have been induced in all species examined at relatively low doses, NDMA is clearly carcinogenic. It is concluded that NDMA is a genotoxic carcinogen, and exposure should be reduced to the extent possible.
