Analytical Method for Quantification of Several Phthalate Acid Esters by Gas Chromatography-Mass Spectrometry in Coffee Brew Samples.

Several phthalate acid esters (PAEs), often called phthalate esters or phthalates, are substances classified as harmful due to their carcinogenic and mutagenic properties, and moreover, as dangerous for humans because they interfere with the endocrine system. In general, phthalic esters are used as plasticizers for different polymers and more other consumer products. In the present study, we describe a simple method to quantify PAEs in coffee brew using a liquid-liquid extraction without purification processes through analysing the obtained organic phase by GCMS in the single ion monitoring mode.

Determination of Selected Phthalates by Gas Chromatography-Mass Spectrometry in Personal Perfumes.

A simple and fast method is proposed to analyze commercial personal perfumes. Our method includes measurement of phthalates, known to be major sources of endocrine disruptor chemicals (EDC), which originate from the less volatile fraction of perfumes. The quantification of phthalates were carried out directly with no sample preparation required on 30 samples of commercial products using gas chromatography and mass spectrometry (GC-MS) as a detector.

The distribution of phthalate esters in indoor dust of Palermo (Italy).

In this work, phthalic acid esters (PAEs): dimethyl phthalate (DMP), diethyl phthalate (DEP), di-n-butyl phthalate, benzyl butyl phthalate, bis(2-ethylhexyl) phthalate, and di-n-octyl phthalate in indoor dust (used as passive sampler) were investigated. The settled dust samples were collected from thirteen indoor environments from Palermo city. A fast and simple method using Soxhlet and GC-MS analysis has been optimized to identify and quantify the phthalates.

Improving end-of-life care: development and pilot-test of a clinical pathway.

Prior studies have revealed deficiencies in the care provided to patients dying from advanced medical illnesses in acute care hospitals. These deficiencies are best addressed through system change, which may include the development of clinical pathways and quality improvement models. The Palliative Care for Advanced Disease (PCAD) pathway was developed by an interdisciplinary team and includes a carepath, a daily flowsheet, and a physician order sheet with standard orders for symptom control.
