Determination of Sub-ppb Level of Phthalates in Water by Auto-SPME and GC-MS Application
A solid-phase microextraction (SPME) method for the analysis of phthalates in water samples was developed on the CTC CombiPAL autosampler GC-MS platform. In this method, the sample preparation process was automated by using a CombiPAL autosampler, including the SPME fiber precondition, adsorption, and desorption, which improve the precision of the SPME method. The extraction temperature, extrac...
متن کاملEcological Correlation between Arsenic Level in Well Water and Age-adjusted Mortality from Malignant Neoplasms1
A significant dose-response relation between ingested arsenic and several cancers has recently been reported in four townships of the endemic area of blackfoot disease, a unique peripheral artery disease related to the chronic arsenic exposure in southwestern Taiwan. This study was carried out to examine ecological correlations between arsenic level of well water and mortality from various mali...

متن کاملEffect of Well Disinfection on Arsenic in Ground Water
Domestic water wells are routinely subjected to in situ chemical disinfection treatments to control nuisance or pathogenic bacteria. Most treatments are chlorine based and presumably cause strongly oxidizing conditions in the wellbore. Water resource managers in Wisconsin were concerned that such treatments might facilitate release of arsenic from sulfide minerals disseminated within a confined...
متن کاملWell characteristics influencing arsenic concentrations in ground water.
Naturally occurring arsenic contamination is common in ground water in the upper Midwest. Arsenic is most likely to be present in glacial drift and shallow bedrock wells that lie within the footprint of northwest provenance Late Wisconsinan glacial drift. Elevated arsenic is more common in domestic wells and in monitoring wells than it is in public water system wells. Arsenic contamination is a...
