Matrix effect (ME) is unavoidable in multiresidue pesticide analysis, even when using highly
advanced instruments, and differences in MEs can affect residue analytical accuracy due to …

The paper represents the first review of solvent extraction techniques utilizing the low-
temperature partitioning/purification (LTP) approach. Initially conceived in the 1960s to purify …

This study was undertaken to evaluate the effectiveness of several household practices
(washing with water or acidic, alkaline, and oxidizing solutions, and peeling) in minimizing …

The components of seven matrices in the analysis of 11 pesticides by GC-ECD were
analysed. The matrix effect was calculated based on the changing of chromatographic …

This work describes the optimization and validation of a method employing solid–liquid
extraction with low temperature partitioning (SLE/LTP) together with analysis by gas …

Two methods, based on dispersive liquid–liquid microextraction (DLLME) and Quick, Easy,
Cheap, Effective, Rugged, and Safe (QuEChERS), have been developed, validated and …

Urine is one of the biological matrices most used for detecting human contamination, as it is
representative and easily obtained via noninvasive sampling. This study proposes a fast …

This study aims to develop and validate a method to determine OCPs in fish tissues,
minimizing the consumption of sample and reagents, by using a modified QuEChERS along …

This paper investigates a strategy as a quality control parameter, using standard surrogate
and determination of a relation factor for determination of parathion-methyl, chlorpyriphos …

The expansion of monocultures to regions close to conservation areas has put biodiversity
at risk, mainly due to the intense use of pesticides. Anurans are highly susceptible to …
