An evaluation of the 'GGP' personal samplers under semi-volatile aerosols: sampling losses and their implication on occupational risk assessment

21-10-2014 | George Constantin Dragan; Dietmar Breuer; Morten Blaskowitz; Erwin Karg; Schnelle-Kreis Juergen; Jose Manuel Arteaga ..., Journal of Environmental Monitoring, 2014

Semi-Volatile (SV) aerosols still represent an important challenge to industrial hygienists due to toxicological and sampling issues. Particularly problematic is the sampling of hazardous SV that are present in both particulate and vapour phases at a workplace. In this study we investigate the ...

Factors influencing uncertainties of in vivo bone lead measurement using a 109Cd K X-ray fluorescence clover leaf geometry detector system

21-10-2014 | Sepideh Behinaein; David R. Chettle; Leonora Marro; Morie Malowany; Mandy Fisher; David E. B. Fleming; Norm Healey; ..., Journal of Environmental Monitoring, 2014

A 109Cd K X-ray fluorescence (KXRF) measurement system consisting of four detectors in clover-leaf geometry is a non-invasive, low-radiation-dose method of measuring bone lead concentration. Its high precision in estimating the bone lead content makes it a promising tool for the determination of ...

Applications of Polyparameter Linear Free Energy Relationships in Environmental Chemistry

17-10-2014 | Satoshi Endo; Kai-Uwe Goss, Environmental Science & Technology, 2014

Partitioning behavior of organic chemicals has tremendous influences on their environmental distribution, reaction rates, bioaccumulation, and toxic effects. Polyparameter linear free energy relationships (PP-LFERs) have been proven to be useful to characterize the equilibrium partitioning of ...

Warming Influences Mg2+ Content, While Warming and Acidification Influence Calcification and Test Strength of a Sea Urchin

17-10-2014 | Maria Byrne; Abigail M. Smith; Samantha West; Marie Collard; Philippe Dubois; Alexia Graba-landry; Symon A Dworjanyn, Environmental Science & Technology, 2014

We examined the long-term effects of near-future changes in temperature and acidification on skeletal mineralogy, thickness, and strength in the sea urchin Tripneustes gratilla reared in all combinations of three pH (pH 8.1, 7.8, 7.6) and three temperatures (22 °C, 25 °C, 28 °C) from the early ...

Nitrite Reduction Mechanism on a Pd Surface

17-10-2014 | Hyeyoung Shin; Sungyoon Jung; Sungjun Bae; Woojin Lee; Hyungjun Kim, Environmental Science & Technology, 2014

Nitrate (NO3–) is one of the most harmful contaminants in the groundwater, and it causes various health problems. Bimetallic catalysts, usually palladium (Pd) coupled with secondary metallic catalyst, are found to properly treat nitrate-containing wastewaters; however, the selectivity toward N2 ...
