1984 | 1985 | Public Electricity and Heat Production | Miners strike resulting in a reduction in the consumption of coal and an increase in the consumption of alternative fuels in power stations for that year | Decrease in emissions |
Acute exposure to selenium by inhalation results in respiratory effects such as irritation to the mucous membranes, severe bronchitis and bronchial pneumonia.
Selenium emissions have declined by 86% since 1990. The majority of selenium emissions in earlier years were from coal-fired power stations in particular and coal combustion generally, but emissions from coal combustion have fallen by 99.5% since 1990 as coal use has declined, contributing only 2% of UK emissions in 2023. Whereas, iron and steel production accounted for 6% of total emissions. The use of selenium by the glass industry is also a significant source – 15% of emissions in 1990 and 10% in 2023, however the mass emitted has been reduced by 90% over that period by eliminating the use of selenium or control on particulate emissions from glass furnaces.
