PROGRESS OF TOTAL PETROLEUM HYDROCARBONS (TPHs) TREATED WITH BIOSOLVENT IN A SIMULATED OIL SPILL ON SANDY BEACH MICROCOSMS

Experiments with microcosms of sand corresponding to high, mid and low intertidal area were contaminated with crude oil and treated with biosolvent. Two treatments were done. The first (treatment 1) treating the sand 5 days before the event of contamination and the second (treatment 2) treated immed...
