A new, comprehensive survey of day care centers by UC Berkeley researchers found that, overall, the environmental quality in child care settings was similar to other indoor environments, but that levels of formaldehyde and several other contaminants exceeded state health guidelines. Cleaning- and sanitizing-related chemicals were also present in the air, and sometimes at higher levels, than in comparable studies on homes. |

Are gasoline-fueled cars or large diesel trucks the bigger source of secondary organic aerosol (SOA), a major component of smog? UC Berkeley researchers have stepped into this debate with a new study, published today in the Proceedings of the National Academy of Sciences, that says diesel exhaust contributes 15 times more than gas emissions per liter of fuel burned. |

Bisphenol A (BPA), an estrogen-like compound that has drawn increased scrutiny in recent years, has been linked to changes in thyroid hormone levels in pregnant women and newborn boys, according to a new study by researchers at UC Berkeley. The new findings add to growing health concerns about BPA, a chemical found in hard plastics, linings of canned food, dental sealants, and sales receipts on thermal paper, which is coated with a chemical that changes color when exposed to heat. |

Routinely used to help clean up toxic metals at contaminated sites, bacteria and other soil microbes are fed to boost their ability to turn soluble metals into solids that won’t leech into streams or aquifers. UC Berkeley scientists have now dug into the soil of one of these heavy metal contaminated sites to analyze the genes of the underground microbial community in hopes of finding ways to help improve the microbes’ ability to remediate toxic metal contamination. |

Two new studies by scientists at UC Berkeley provide a clearer picture of why some species move in response to climate change, and where they go. The two studies exemplify the type of research being explored through the Berkeley Initiative in Global Change Biology, or BiGCB, an ambitious effort to better understand and predict how plants and animals will respond to changing environmental conditions by studying how they have responded to earlier periods of climate change. |
