Ve­hi­cle pol­lu­tion threat to un­born

Sunday Mail (UK) - - Lorna Hughes -

Preg­nant women are more likely to suf­fer a mis­car­riage if they breathe in high lev­els of air pol­lu­tion, a study sug­gests.

Re­searchers in the US found a 16 per cent in­crease in the risk of mis­car­riage among women ex­posed to raised lev­els of ni­tro­gen diox­ide, a gas cre­ated by petrol and diesel ve­hi­cles.

The warn­ing comes amid height­ened con­cern over air pol­lu­tion’s po­ten­tial links to a grow­ing list of dis­eases and con­di­tions in­clud­ing stroke, de­men­tia and autism.

The re­search saw doc­tors an­a­lyse the records of 1300 women who sought help at Utah Univer­sity’ s emer­gency depart­ment fol­low­ing mis­car­riage be­tween 2007 to 2015.

The team found a higher risk of mis­car­riage for women within seven days of a spike in the lev­els of air pol­lu­tants in­clud­ing small par­tic­u­late mat­ter and ni­tro­gen diox­ide.

The par­tic­u­late mat­ter did not ap­pear to raise the risk of mis­car­riage but the ni­tro­gen diox­ide did.

The find­ings were de­scribed as “up­set­ting” by pro­fes­sor Matthew Fuller, who led the study at the univer­sity.

He added: “We need to work to­gether as a so­ci­ety to find con­struc­tive so­lu­tions.”

Fuller said preg­nant women can man­age their risk by try­ing to avoid out­door phys­i­cal ac­tiv­ity on poor air qual­ity days.
