Chronology of Organochlorine Pesticides (OCPs) releases and interactions with sediment characterisitcs in the Eure River, France

For that, sediment cores MAR16-02 and MAR15-01 were collected downstream of the Eure River watershed, the main tributary of the Seine estuary (France). The analysis of particulate OCPs in the MAR16-02 sediment core was performed using microwave-assisted extraction, with toluene:acetone mixture for extraction.

Following the microwave-assisted extraction, a gas chromatograph (7890B, Agilent, US) coupled to a mass spectrometer (MS; 7000C) was used to measure the concentrations. Organic matter parameters from MAR15-01 sediment core was measured by Rock-Eval 6.
