A view of the Eiffel Tower seen through thick smog, on March 14, 2014, in Paris. Fine particle pollution in several French cities continued unabated today as the modest measures taken by local authorities failed to solve the underlying problem. French non-governmental organization (NGO) Ecologie Sans Frontiere (Ecology without borders) confirmed on March 11 that they had filed a criminal complaint in Paris to denounce the "health scandal" of air pollution, as several regions of France experienced high levels of particulate pollution.
