Traduction de «Concentration létale 50 % - 6 heures cumulée » (Français → Anglais) :

The test piece, which shall be stressed to 20 per cent elongation, shall be exposed to air at +40 °C with an ozone concentration of 50 parts per hundred million during 120 hours.

the global nature of climate change calls for the widest possible cooperation by all countries, and their participation in an effective, cost-efficient and appropriate international response, in accordance with their common, but differentiated responsibilities and respective capabilities; the EU therefore looks forward to engaging with all Parties to the Convention in an open dialogue on what further action is required as a next step to move towards the ultimate objective of the Convention; the relevant Council formations should reinvigorate their efforts to integrate climate change objectives into their policy areas; recent scientifi ...[+++]c research and work under the IPCC indicate that it is unlikely that stabilisation of concentrations above 550 ppmv CO equivalent would be consistent with meeting the 2°C objective and that in order to have a reasonable chance to limit global warming to no more than 2°C, stabilisation of concentrations well below 550 ppmv CO equivalent may be needed; recent scientific research and work under the IPCC indicate that keeping this long-term temperature objective within reach will require global greenhouse gas emissions to peak within 2 decades, followed by substantial reductions in the order of at least 15% and perhaps by as much as 50% by 2050 compared to 1990 levels; in view of the global emission reductions required, global joint efforts are needed in the coming decades, in line with the common, but differentiated responsibilities and respective capabilities, including significantly enhanced aggregated reduction efforts by all economically more advanced countries.

According to the ECOFIN Directorate-General’s econometric simulations model, if the price of a barrel of oil stays at 50 dollars – and today I believe a barrel of Brent stands at over 51 dollars – the effect would be an accumulated growth loss over three years of almost one point of gross domestic product, if the price of a barrel remains at 50 dollars throughout that period.

The main area of concern identified is the companies' combined strong position in a number of ceramic sanitary ware products in the Nordic countries (Norway, Finland, Sweden, Iceland, Denmark), where they would account for over three quarters of the market, and in the Benelux, where the concentration would lead to combined market shares above 50%.

Concentrations are very high in the few minutes following absorption, varying between 50 and 1,000 ng/ml, but then decline very quickly in the hours that follow, though they remain detectable for an average of four to six hours.
