Analytical methods of biological monitoring for exposure to pesticides: Recent update
Margariti, M. G.; Tsakalof, A. K.; Tsatsakis, A. M. (2007)Extensive use of synthetic pesticides for agricultural and nonagricultural purposes began in the past 50 years. As a result of their wide and extensive application, exposure to hazardous pesticides is a concern to the ... -
Correlation between plant growth regulator release rate and bioactivity for the series of newly synthesized phytoactive polymers
Shtilman, M. I.; Tzatzarakis, M. N.; Voskanyan, P. S.; Tsakiris, I. N.; Tsakalof, A. K.; Tsatsakis, A. M. (2006)Phytoactive polymers are high molecular weight systems in which a plant growth regulator (PGR) unit is attached to the polymeric chain by a hydrolyzable chemical bond. The release rate of the PGR is linked to the biological ... -
Development and application of GC-MS method for monitoring of long-term exposure to the pesticide cypermethrin
Kavvalakis, M. P.; Tzatzarakis, M. N.; Alegakis, A. K.; Vynias, D.; Tsakalof, A. K.; Tsatsakis, A. M. (2014)Cypermethrin (CPMN) is a synthetic pyrethroid used as an insecticide in large-scale commercial agricultural applications as well as for domestic purposes. In the present study a gas chromatography-mass spectrometry (GC-MS) ... -
Development and application of LC-APCI-MS method for biomonitoring of animal and human exposure to imidacloprid
Kavvalakis, M. P.; Tzatzarakis, M. N.; Theodoropoulou, E. P.; Barbounis, E. G.; Tsakalof, A. K.; Tsatsakis, A. M. (2013)Imidacloprid (IMI) is a relatively new neuro-active neonicotinoid insecticide and nowadays one of the largest selling insecticides worldwide.

Tsakalof, A. K.; Gkagtzis, D. C.; Koukoulis, G. N.; Hadjichristodoulou, C. S. (2012)Monitoring of estradiol and its metabolites in biological samples is essential for the accurate diagnosis of a number of endocrine diseases. In this study, a sensitive, precise and specific GC-MS/MS method for the ... -
Hypospadias in offspring is associated with chronic exposure of parents to organophosphate and organochlorine pesticides
Michalakis, M.; Tzatzarakis, M. N.; Kovatsi, L.; Alegakis, A. K.; Tsakalof, A. K.; Heretis, I.; Tsatsakis, A. (2014)We have currently evaluated the possible association between hypospadias and exposure to organophosphorus (OP) and organochlorine (OC) pesticides. For this purpose, we measured the dialkyl phosphate metabolites of ... -
