Oral question asked in the House of Lords, by Lord Forsyth of Drumlean (Conservative). It was answered by Lord Rooker (Labour) on Monday, 16 July 2007.

Barometers

Question: How many people have suffered harm as a result of contact with mercury barometers.

Answer: My Lords, since 2005, the chemical incidents surveillance system has reported four domestic incidents involving mercury spills from barometers. Five people were confirmed as having been exposed, of whom one exhibited symptoms. However, mercury released from barometers persists in the environment and, as such, can indirectly lead to risks to human health, such as children’s mental development. The proposed restrictions on the sale of new mercury instruments are a proportionate response to those concerns.
