NDMA formation during chlorination and chloramination of aqueous diuron solutions.
Formation of the potent carcinogen N-nitrosodimethylamine (NDMA) during chlorine disinfection of water containing secondary amines is now generally acknowledged. The phenylurea herbicide diuron is one of the most widely used herbicides in California, has been frequently detected in California's water sources with a transient nature of appearance, and has a structure that suggests it might be an...
متن کاملInfluence of nitrogen source on NDMA formation during chlorination of diuron.
N-Nitrosodimethylamine (NDMA) is formed during chlorination of water containing the herbicide diuron (N'-(3,4-dichlorophenyl)-N,N-dimethylurea) but formation is greatly enhanced in the presence of ammonia (chloramination). Groundwater impacted by agricultural runoff may contain diuron and relatively high total nitrogen concentrations; this study examines the impact of the nitrogen form (ammoniu...
متن کاملEnvironmental Fate of Diuron
This document reviews the environmental fate of diuron. The chemical (IUPAC) name for diuron is N-(3, 4-dichlorophenyl)-N, N-dimethylurea (C9H10Cl2N2O). In California, registered products containing the active ingredient diuron include Direx, Karmex, and Krovar (in combination with bromacil), among others. Diuron is often used in combination with other herbicides such as bromacil, hexazinone, p...
متن کاملDiuron degradation by bacteria from soil of sugarcane crops
The isolation of microorganisms from soil impacted by xenobiotic chemicals and exposing them in the laboratory to the contaminant can provide important information about their response to the contaminants. The purpose of this study was to isolate bacteria from soil with historical application of herbicides and to evaluate their potential to degrade diuron. The isolation media contained either g...
متن کاملIrrigation with Recycled Wastewater: The NDMA Story
BACKGROUND The scarcity of water supply in many arid regions, combined with the need for disposal of large volumes of wastewater, has led to an increased use of recycled water for landscape irrigation. Although this practice has been employed for decades in many parts of the world, public health officials recently have begun to express concerns about the potential for wastewater-derived trace c...
