Extracting PCDD/F from Soil and Grass Samples
We are presenting the use of BÜCHI's Extraction Unit B-811 for isolating polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/F) from solid environmental samples (soil, grass) under standard conditions and by means of hot extraction. The extracts received will be further processed by means of an internationally recognized method and analyzed with high-resolution GC/MS in the single-ion ...

Parallel Pressurized Solvent Extraction of PCDD/PCDF, PBDE, and PFC from Soil, Sludge, and Sediment Samples
The efficacy of pressurized solvent extraction with BUCHI's new SpeedExtractor was examined for the extraction of dioxins/furans (PCDDs/PCDFs), polybrominated diphenyl ethers (PBDEs), and perfluorinated compounds (PFCs) from different environmental matrices: PCDDs/PCDFs from soil samples, PFCs from soil and sewage sludge, and PBDEs from lake sediments. The results of the extraction of PCDDs/PCDFs ...

Soil Sampling under Buildings and Solving Vapor Intrusion using Horizontal Drilling
The Issue: The New Jersey Department of Environmental Protection (NJDEP) mandated soil and groundwater sampling under an active pharmaceutical company manufacturing building in order to address vapor intrusion inside the building. Installation of vertical borings and wells through the building slab was not practicable without profound disruption of manufacturing activities inside the building. ...

Antagonism between clinical and environmental isolates of
Pseudomonas aeruginosa against coliformsWater is essential to life, yet many people worldwide do not have access to clean drinking water and suffer or die from preventable diseases caused by unsafe water. Microbiological water analysis is based on coliform bacteria, but these microorganisms can have their growth affected by others, such as Pseudomonas aeruginosa. A total of 60 isolates of P. aeruginosa was investigated in this study ...

Comparing Field Portable X-Ray Fluorescence (XRF) To Laboratory Analysis Of Heavy Metals In Soil
ABSTRACT Field portable x-ray fluorescence (XRF) continues to gain acceptance as a complement to traditional laboratory testing of metal contaminated soil. The quality of data produced by field XRF varies with site conditions, soil composition, and sample preparation. Quality assurance protocols for the field method usually require that a number of field samples be split and sent to a ...
