Geologist alleges Shell are hiding health hazards from oil spills in Nigeria

Royal Dutch Shell's Nigeria subsidiary "fiercely opposed" environmental testing and is concealing data showing thousands of Nigerians are exposed to health hazards from oil spills, according to a geologist.

The hazards stem from a stalled clean-up of the worst oil spills in the west African nation's history, according to German geologist Kay Holtzmann, who was contracted by the Dutch-British multinational.
