Heat dangers forgotten in the battle against air pollution
11 October 2005
Ozone is being wrongly blamed for many of the deaths during hot weather spells, finds a new ¹û¶³Ó°Ôº study.
The study, published online in the journal Environmental Research, modelled the daily mortality rate of people over 65 (who suffer most of the heat-related deaths) in Greater London from 1991 to 2002. The model included daily temperatures, humidity, sunshine and wind and assessed any effects of atmospheric ozone, particulates and sulphur dioxide. ¹û¶³Ó°Ôº researchers then analysed general mortality trends for days when mean air temperatures exceeded 18ËšC.
