Yet another study that confirms the urgent need to switch to cleaner energy sources for health reasons. Here we have unborn children affected by the air pollution their mothers breathe. Burning fossil fuels releases polycyclic aromatic hydrocarbons (PAHs) which we all breathe in but these chemicals affect the mental development of unborn children. Other new studies show smog causes increases in heart attacks, and reduces blood’s ability to transport oxygen.

So why the high-profile fight over climate change and urgent need to reduce fossil fuel use? Might it happen that fossil energy companies desperate to protect hundreds of billions of dollars of profits, actively encourage (if not directly fund) confusion regarding the inconvenient scientific results on climate and public health? — Stephen

April 2010 — A study by the Columbia Center for Children’s Environmental Health (CCCEH) carried out in Krakow, Poland has found that prenatal exposure to pollutants can adversely affect children’s cognitive development at age 5, confirming previous findings in a New York City (NYC) study.

Researchers report that children exposed to high levels of polycyclic aromatic hydrocarbons (PAHs) in Krakow had a significant reduction in scores on a standardized test of reasoning ability and intelligence at age 5. The study findings are published today online in Environmental Health Perspectives. Continue reading →
