The samples were collected in sterilized, sealed pack polythene bags which were later ground and sieved through a 2-mm pore size sieve and stored at 4 °C for further physicochemical and microbial assays for isolation of potential PAH-degrading microorganisms.
For each point, the doctor must open a new, sealed pack containing the sterile needle, to reinforce the credibility of the procedure.
The skulls of the six dead seals, packed in boxes marked "evidence," sit in a laboratory freezer at the Woods Hole Oceanographic Institution, where researchers conducted CT scans to confirm they were shot and necropsies to try to answer crucial questions.
