Endosulfan in wind-transported African dust depositions in Crete.

The presence of endosulfan in samples of African dust after a typical red dust storm in May 2007 was investigated. The samples were collected from a remote and mountainous area of Crete (Greece) where olive groves are cultivated. Endosulfan I, endosulfan II and endosulfan sulphate were detected at concentrations of 2.7, 1.4 and 1.1 ng/g, respectively, indicating that long range aeolian dust transport could be a possible source of contamination of olive cultivations.

Facile and rapid determination of contamination in sulphur pesticide formulations by liquid chromatography-tandem mass spectrometry.

Up to 7% of pesticide products in the European market are illegal, counterfeit or of poor quality. As a result, regulatory authorities are required to determine a wide variety of impurities in many different pesticide formulations. A simple, rapid and exceptionally reliable LC-MS-MS method for the determination of carbendazim residual quantities in sulphur formulations, used in organic agriculture, has been developed and validated. Linearity of response was established (R (2) = 0.9997) over a wide range of concentrations (0.01-2 microg/mL). Recovery ranged from 94% to 101%. LOD and LOQ were 0.003 microg/mL and 0.005 microg/mL, respectively, and lack of interference was confirmed.
