This study determined pesticide residue levels in some fruits Tokat province, Turkey and assessed health risks associated with the residues. A analytical method was validated to determine 260 pesticides by using liquid chromatography–tandem mass spectrometry (LC–MS/MS). Pesticide solutions (10 50 µg kg­¹) were applied pesticide-free apple matrix for validation of method. The linearities (R2), l...

A new approach for accurate quantitative determination by fluorine nuclear magnetic resonance ( 19 F NMR) spectroscopy is presented and discussed. 19 F NMR spectroscopy has similar properties to 1 H NMR spectroscopy except for the wide chemical shift dispersion, which is the main difference between the two techniques. The off-resonance effect, which is caused by the chemical shift difference be...

Mosquito larvicides derived from microbial organisms and insect growth regulators have been increasingly used to control mosquito larvae worldwide. Their relative target specif‐ icity, nontarget safety, and environmentally friendly profile have been well documented. The current chapter was intended to review and analyze the relevant information regard‐ ing resistance development and resistance ...

In 2009, Cabo Verde diagnosed the first dengue cases, with 21,137 cases reported and Aedes aegypti was identified as the vector. Since the outbreak, chemical insecticides and source reduction were used to control the mosquito population. This study aimed to assess the susceptibility of A. aegypti populations from Santiago, Cabo Verde to insecticides and identify the mechanisms of resistance. Sa...
