A Dieldrin Case Study: Another Evidence of an Obsolete Substance in the European Soil Environment

Soil constitutes a central environmental compartment that, due to natural and anthropogenic activities, is recipient of several contaminants. Among them, organochlorine pesticides are major concern, even though they have been banned decades ago in the European Union, their persistence health effects can elicit. In presented work, gas chromatographic tandem mass spectrometric (GC-MS/MS) developed method was applied soil samples after suspected potential use formulations containing active substance. One sample positive dieldrin at 0.018 mg kg−1. Predicted concentration (PECsoil) considering single application this substance potentially attributed finding its past use. The subsequent risk assessment showed negligible non-carcinogenic tolerable carcinogenic risk. latter signifies that repetitive prolonged sampling unveil pragmatic projection persistent chemicals’ residues soil.
