Triple quadrupole GC-MS

New generation of GC-MS/MS from Thermo Fisher Scientific, designed to deliver more sensitivity at faster speeds than its predecessor



Contaminants: novel methods for detection

Two new studies propose novel ways to identify pesticides in food and rogue vegetable oils in olive oil. Eugene McCarthy reports



Checking for critical amounts of residual pesticides

To address the increasing demand to reliably check for critical amounts of residual pesticides in foods, feed additives and veterinary drugs Shimadzu is releasing the company’s GC/MS Method Package Ver. 2 for Residual Pesticides in Foods. The package has been developed to improve the speed and efficiency of using GC/MS technology to analyse as many as 800 different residual pesticides



Simplifying pesticides analysis

New package from Thermo Fisher Scientific contains more than 700 pesticides, PCBs and dioxins



Organic pesticides not always greener

A new study reveals some organic pesticides can have a higher environmental impact than conventional pesticides because the organic product may require larger doses.



Storm runoff contaminated with household pesticides

Pyrethroids, among the most widely-used home pesticides, are winding up in California rivers at levels toxic to some stream-dwellers, possibly endangering the food supply of fish and other aquatic animals.



Inexpensive test for pesticides in foods

Scientists in Canada are reporting the development of a fast, inexpensive "dipstick" test to identify small amounts of pesticides that may exist in foods and beverages.



Precise screening for pesticides, mycotoxins and veterinary drugs

High resolution and precise mass accuracy is a perfect combination for food and feed analysis in complex matrices. Markus Kellmann, Andreas Wieghaus, Helmut Muenster, Lester Taylor and Dipankar Ghosh report.



Spices provide eco-friendly pesticides

Scientists in Canada are reporting exciting new research on these so-called 'essential oil pesticides' or 'killer spices' and represent a relatively new class of natural insecticides that show promise as an environmentally-friendly alternative.



Analysers detect pesticides in food

Dr Specht & Partner Chemical Laboratories, a member of Eurofins Scientific Group, has recently purchased an API4000LC/MS/MS System to work alongside two existing API2000LC/MS/MS Systems used to analyse pesticide residues for the food industry.



Pesticides not yet proven guilty of causing honeybee declines

The impact of crop pesticides on honeybee colonies is unlikely to cause colony collapse, according to a paper in the journal Science. More research is now needed to predict the impact of widely-used agricultural insecticides, called neonicotinoids, on honeybee populations.



Coffee and bats mean no pesticides

If you get a chance to sip some shade-grown Mexican organic coffee, please pause a moment to thank the bats that helped make it possible.
