Japanese researchers publishing in the May issue of Environmental Research have found a link between prenatal exposure to dioxin-like compounds -- such as the pollution that comes from waste burning from forest fires -- and an increased risk of ear infections later in life.
The team followed 364 children from before birth to 18 months of age. Those tots who were in the highest exposure group while in the womb were five times as likely to be predisposed to ear infections as the least exposed infants. Baby boys were especially at risk.
So for expecting moms: no dancing near forest fires or holding bonfire parties to burn all you hubbies favorite man-toys. You'll just have to find other ways to have some fun.
