Man-made pollution is managing to poison babies before they're even babies.
Scientists have found the first evidence that particles of air pollution travel through pregnant women’s lungs and lodge in their placentas.
Toxic air is already strongly linked to harm in foetuses but how the damage is done is unknown. The new study, involving mothers living in London, UK, revealed sooty particles in the placentas of each of their babies and researchers say it is quite possible the particles entered the foetuses too.
...The research is being presented Sunday at the European Respiratory Society’s (ERS) international congress in Paris. “This research suggests a possible mechanism of how babies are affected by pollution while being theoretically protected in the womb,” said Prof Mina Gaga, who is ERS president and at the Athens Chest Hospital in Greece.
“This should raise awareness amongst doctors and the public regarding the harmful effects of air pollution in pregnant women,” she said, noting that harm to foetuses can occur even below current European Union pollution limits. “We need stricter policies for cleaner air to reduce the impact of pollution on health worldwide because we are already seeing a new population of young adults with health issues.”
Unicef executive director Anthony Lake recently warned of the danger of air pollution to babies: “Not only do pollutants harm babies’ developing lungs, they can permanently damage their developing brains – and, thus, their futures.”
Separate research, also presented at the ERS congress, found that children with early onset and persistent asthma fared far less well in education than those without the condition. Asthma in children has long been linked to air pollution.
