Important factors in this exposure were the place of residence, maternal age, passive exposure to tobacco smoke and consumption of oily fish. The results suggest that fish consumption is the main source of exposure to mercury in the sample population studied.
The work carried out at the University of Granada also suggests that in Granada, children's health risk from exposure to trihalomethanes via drinking water can be considered to be significantly lower than in other areas of the country, and that air pollutant NO2 concentrations (measured in the external environment of the study area) were also lower than those described in other Spanish cities. Traffic of motor vehicles is the main source of emission of these pollutants in the study area.
Moreover, the research also revealed that there is a direct relationship between children's passive exposure to tobacco smoke and the use of gas stoves inside houses, and the presence of 1-hydroxypyrene, an indicator of exposure to damaging health air pollutants.
Researchers warn that although environmental exposure levels found in children are low enough not to cause any obvious concern, they could have an impact on child development in the long-term, only appearing as symptoms many years after first exposure. Consequently, they explain, "whatever the extent of involvement of environmental exposures in the etiology of the disease, the simple fact of acting very early in life opens the door to a transcendental field in public health: the possibility of applying early prevention measures to minimize problems."
