QuEChER method for air microbiological monitoring in hospital environments
The Journal of Infection in Developing Countries, 2020 Introduction: Nosocomial pathogens have become a priority issue for public health, since they are responsible for increased morbidity and mortality in hospitalized patients and the development of multi-resistant microorganisms, as well. Recent studies found strong evidence that airborne transmission plays a key role in many nosocomial infections. Thus,

Application of QuEChERS for Determining Xenobiotics in Foods of Animal Origin [PDF]
Journal of Analytical Methods in Chemistry, 2017 The use of pesticides and veterinary drugs results in the appearance of residues of xenobiotics in foods. Thus, several methods have been developed for monitoring them; however, most are tedious and expensive. By contrast, the QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) methodology involves a microextraction that yields small samples and

Residue Analysis of Insecticides in Potatoes by QuEChERS-dSPE/UHPLC-PDA [PDF]
Foods, 2020 Insecticides are broadly applied in agriculture to defend crops from illnesses and pest attacks, consequently guaranteeing high production. However, their residual deposits in food products are becoming a main concern with regard to human consumption. As such, sensitive analytical methods should be developed to assess, prevent and control insecticide ...
