Abstract
A method for the analyses of pyridine in environmental samples is described. For soil samples a distillation procedure followed by an extraction, an acidic extraction or a Soxhlet extraction can be used. For water samples a distillation procedure followed by extraction can be employed. Deuterated pyridine is used as an internal standard and the extracts are analyzed by GC-MS. The recoveries of the methods are higher than 80%; the detection limits for pyridine are 0.01 mg/kg for soil samples and 0.2 μg/l for water samples.
