TheDevelopmentalEffectsofNicotineonChickEmbryos
More than 22 million American women smoke and approximately 25% of these women continue to smoke during pregnancy (Lambers and Clark 1996). Cigarette smoke has long been associated with increased health risks to the unborn baby. It contains thousands of different chemicals that could be harmful to various processes of development. One of the most hazardous chemicals in cigarettes is nicotine. Nicotine, the chief alka......阅读全文
