One-step sample preparation technique for broad spectrum gas chromatographic/mass spectrometric determination of organic priority pollutants in water.

A rapid and cost-effective sample preparation technique is described for the qualitative and quantitative determination of a broad spectrum of organic contaminants in water. The technique involves simultaneous-in-situ acetylation of phenols with acetic anhydride and one-step extraction of phenol acetates and basic and neutral organic compounds from water. The extract is concentrated and analyzed by gas chromatography/mass spectrometry. The recovery and precision data of selected base, neutral, and phenolic compounds are given. The advantages and disadvantages of the in-situ acetylation/extraction technique are discussed.

A theoretical model of support network conflict experienced by new mothers.

Women who have had their first child often receive help from persons comprising their support network. Although this help is well-intentioned, studies show that it may be associated with conflict between the new mother and others within the support network. Identification of factors influencing support network conflict is important so that nursing interventions can be implemented to reduce or avoid conflict. This article explores the topic of support network conflict and proposes a theoretical model of factors influencing support network conflict.
