The opinion of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) of 2010, on the health issues concerning LEDs, suggested banning public use of lamps which were in the moderate Risk Group 2, especially those with a high blue component in places frequented by children.

Problem: Though Brazilians of at least partial African heritage make up a large percentage of the population, few blacks have been elected as politicians. The city of Salvador, Bahia, for instance, is 80% people of color, but voters have not elected a mayor of color. Journalists like to say that US cities with black majorities, such as Detroit and New Orleans, have not elected white mayors since after the civil rights movement, when the Voting Rights Act of 1965 protected the franchise for minorities, and blacks in the South regained the power to vote for the first time since the turn of the 20th century.
