§ Ian LucasTo ask the Secretary of State for Environment, Food and Rural Affairs what estimate she has made of the amount of mercury vapour emitted in each of the last five years by the burning of mercury (II) thiocyanate in pyrotechnic products. [34522]
§ Mr. MeacherThere is a wide range in estimates of the tonnage of fireworks used annually in the UK. However on current information our best estimate is that emissions of mercury from this source may be in the order of 150kg per annum.
§ Ian LucasTo ask the Secretary of State for Environment, Food and Rural Affairs if she will estimate the amount of mercury vapour emitted in each of the last five years by the detonation of caps in toy cap guns. [34524]
§ Mr. MeacherCurrently there is only limited data available on emissions of mercury from toy caps, but it is an area in which we are looking at ways to improve our estimates. Our current best estimate is that emissions from this source may be in the order of 150kg per annum.
