Since his early years, the Viscount has never been a fan of automobile pollution. One of his earliest memories was of writing a charming haiku about the dangers of carbon dioxide. Since then, he has dedicated a portion of his life, albeit a small portion, to fighting the dangers of pollution. Growing up in a small charming rural villiage, he was not subject to the noxious exhaust fumes, that at the time, carried poisonous lead along with many poisonous gases. Of course, now all the rage is to concern ourselves with carbon dioxide and its impact on climate change. It is easy to forget that the exhausts remain a poison.
Upon this era of gaseous concerns for climate change emerges
a study demonstrating the impact of automobile exhuast on childrens' intelligence. These types of study are difficult to conduct. Does one take a test group of children and expose them daily to a set dose of poisonous gas? While this would be an interesting approach, it is entirely unethical and inappropriate. Instead, these studies are often done through epidemiological analysis. There are many confounding factors that must be examined through these studies such as schools, family life, and income. However, in the study under discussion today, the researchers gave air samplers to pregnant women and examined the exposures they had during their last trimester of pregnancy. The researcher then studies the eventual health outcomes of the children, including IQ. Of course, there still could be confounding factors to the study, but it is clear that the children exposed to high levels of automobile exhaust developed lower IQ's. Intersting stuff, and a confirmation of the Viscount's early efforts at poetry.
