Inert gas asphyxiation lacks oxygen and consists of an asphyxiant gas (one or more of argon, nitrogen or carbon dioxide), causing the animals to lose consciousness. Argon and nitrogen are important components of a gassing process which seem to cause no pain, and for this reason many consider some types of controlled atmosphere killing more humane than other methods of killing. However, "stunning" is often done using carbon dioxide. If carbon dioxide is used, controlled atmosphere killing is not the same as inert gas asphyxia, because carbon dioxide at high concentrations (above 5%) is not biologically inert, but rather is toxic and also
Phase-out of incandescent light bulbs in Europe, owing to CFLs' inferior colour representation. The European Association for the Co-ordination of Consumer Representation in Standardisation (ANEC) has called for a speedy reduction of the mercury levels contained within CFLs from the current 5mg limit to 1 mg. The European Consumers' Organisation, BEUC, said that phasing out incandescent bulbs will be detrimental for people suffering light-related health issues, and called for the continued availability of incandescent bulbs: The EU Regulation falls short of the needs of some consumers who need to use the old-style light bulbs for health-related reasons such as light sensitivity. We call on the
