The research by scientists at the Maxine Dunitz Neurosurgical Institute and Department of Neurosurgery at Cedars-Sinai will be done in laboratory mice and will focus on three - naphthalene, butadiene and isoprene - that often are associated with polluted air.
Long, flexible chains of polyisoprene, which is made up of many individual units of the hydrocarbon isoprene, form an interlocked tangle that allows rubber to compress, stretch and bend without breaking.
However, in 2004, researchers, contrary to popular assumptions, revealed that isoprene likely was involved in the production of particulate matter, tiny particles that can get lodged in lungs, lead to lung cancer and asthma, and damage other tissues as well as the environment--but exactly how was anybody's guess.
These include ethanol, n- and iso-butanol, poly(hydroxyalkanoates), lactic acid, 3-hydroxypropionic acid, diacids (such as succinic, fumaric, and adipic), diols (such as 1,4-butanediol and 1,3-propanediol), isoprene, farnesene, and other olefins from alcohol dehydration: ethylene, propylene, and butadiene.
Poplar, willow or eucalyptus trees, all used as fast-growing sources of renewable wood fuel, emit high levels of the chemical isoprene as they grow, the study said.
