Air pollution could be a factor in up to 2,000 cases of potentially fatal pre-eclampsia each year in the UK, a new study has indicated.
After taking account of various factors, they calculated that one in every 20 (five per cent) cases of pre-eclampsia were linked to ozone levels during early pregnancy.
Lead researcher David Olsson, of the department of public health and clinical medicine at Umea University, said the findings should lead to improved monitoring of women with asthma during pregnancy.
