Riassunto
This study presents an optimized analytical method for the detection
of trace and ultra-trace organo-pesticides in polar lake sediments. The method,
involving both instrumental and experimental stages, successfully identified 26 com-
pounds, including chlorobenzenes, DDX, lindanes, aldrin, atrazine, and newer syn-
thetic molecules. The instrumental stage developed a new dMRM method using
GC-MS/MS, while the experimental stage explored the optimal combination of sol-
vents for extraction and the stationary phase of the SPE technique. The method’s
validity was confirmed on a certified reference material and applied to 16 sediment
samples from Arctic and Antarctic lakes. The findings were then discussed and
correlated with existing literature data, contributing to the field of environmental
analysis.
