Environmental Analysis

From sample prep to low detection levels to automation, environmental analysis provides unique challenges for analytical chemists. Participants in this Technology Forum are Kory Kelly of Phenomenex (Torrance, California) and LCGC Editorial Advisory Board member Pat Sandra of the Research Institute of Chromatography (Kortrijk, Belgium).

Shimadzu Application Note

A simple and sensitive high performance liquid chromatography (HPLC) method with ultraviolet (UV) detection was developed to analyse phenylurea herbicides: – monuron, diuron, linuron, metazachlor and metoxuron – in three soft drink brands and tap water.

The level of pollutants present in water bodies is most commonly judged against set environmental quality standards (EQSs) that vary among different countries.

Chromium is a naturally occurring metal that is widely used in steel making, plating, tanning, paints, dyes, and wood preservation. The most common environmental forms are trivalent Cr(III), hexavalent Cr(VI), and the metallic form Cr.

In response to the environmental challenges during the last decades, several important laws such as the Clean Air Act, the Clean Water Act and the Pollution Prevention Act have been approved.

A method has been proposed that positively identifies over 100 common pesticides using a GC column with MS detection.

EPA Method 1664, Revision A describes the determination of oil and grease from liquid (typically water) samples.

This article describes modifications to US EPA Method 218.6 for detecting dissolved hexavalent chromium in drinking water, to permit a MDL of 0.001 µg/L

This article describes a 2D matrix elimination ion chromatography method to analyse samples containing high levels of matrix ions.

In this review, practical principles and guidelines for designing LC?LC methods are given.

A review of separations of chlorite, chlorate and bromate in water using ion chromatography and their determination.

The N-methylcarbamates and the N-methylcarbamoximes are among the most widely used pesticides in agriculture. Dionex has announced an improved HPLC method for the determination of these chemicals.

The European Union has published new regulations regarding the approved testing methods for detecting marine biotoxins in bivalve molluscs, including oysters and mussels.

Thermo Fisher Scientific?s Global Food Safety Response Centre in Dreieich, Germany has announced that it is monitoring the dioxin crisis in Germany where animal feed additives may have been tainted with industrial fats containing the toxic chemical.

A novel and sensitive approach for analysing high-molecular-weight phthalates is described.

A method based on SPME and GC–MS was developed to analyse chlorophenols and their metabolites in aqueous samples.

A simple and rapid test for cobalt in leguminous plants has been developed that Spanish and Venezuelan chemists claim could provide an alternative to more expensive methods.

Following the accident at Chernobyl Nuclear Power Plant in 1986, the surrounding area remains substantially contaminated with radioactive isotopes. A study into the adaptations of the surrounding plant life has suggested that the plant proteomes remain largely unchanged by the radio contamination.
