Analysis of PBDEs in Sediment Using GC-MS/MS
Polybrominated diphenyl ethers (PBDEs) are brominated flame retardants (BFRs) widely used in plastics. Due to their toxicity and persistence, their industrial production is to be eliminated under the Stockholm Convention. Contamination from PBDEs is widespread in the environment, including in sediments. In order to determine PBDEs in sediments, they need to be separated from a large amount of ...

Improved Determination of Volatile Organic Compounds in Water by SPME and GC/MS: ISO Standard 17943
The analysis of water for volatile organic compounds is important due to their toxicity. The current methods for this determination lack of sensitivity, selectivity or capability for automation. This paper presents the new ISO 17943 Standard using Solid Phase Microextraction (SPME) and GC/MS. The sample preparation by SPME enables low limits of detection and easy automation of the whole method. ...

Analytical methods for PCBs and organochlorine pesticides in environmental monitoring and surveillance: a critical appraisal
Abstract Analytical methods for the analysis of polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) are widely available and are the result of a vast amount of environmental analytical method development and research on persistent organic pollutants (POPs) over the past 30–40 years. This review summarizes procedures and examines new approaches for extraction, isolation, ...
