Global burden of intellectual disability resulting from dietary exposure to lead, 2015

sources and pathways of exposure. Lead adversely affects a number of tissues and organ systems and the severity of effect on each is dependent on the level and duration of exposure. The most sensitive and ...

Development of a QuEChERS-Based UHPLC-MS/MS Method for Simultaneous Determination of Six Alternaria Toxins in Grapes

and anhydrous magnesium sulfate (0.5 g) was established to recover the six Alternaria toxins. After validation by determining the linearity (R2  > 0.99), recovery (77.8–101.6%), sensitivity (limit of ...

Towards the use of ion mobility mass spectrometry derived collision cross section as a screening approach for unambiguous identification of targeted pesticides in food
