The Effects of Second-hand Smoke Exposure on Breast Milk Cotinine and Infant Urinary Cotinine
Background & Aims: Exposure to cigarette smoke affects the health of mothers and infants. The aim of this study was to examine the effects of second-hand smoke exposure on breast milk and infant urinary cotinine during breastfeeding. Methods: This cohort study was conducted on 45 breastfeeding mothers and infants exposed to second-hand cigarette smoke (exposed group), and 40 breastfeeding mothe...
متن کاملExposure to environmental tobacco smoke measured by cotinine 125I-radioimmunoassay.
We describe a polyclonal-antiserum-based 125I-radioimmunoassay for cotinine that is suitable for measuring nonsmokers' passive exposure to tobacco smoke in the environment. The standard curve ranged from 0.25 to 12.0 micrograms/L, with an estimated lower limit of sensitivity of 0.2 microgram/L (95% B/Bo = 0.2 microgram/L; 50% B/Bo = 4.0 micrograms/L). The median within-assay CVs for patients' s...

متن کاملCotinine analytical workshop report: consideration of analytical methods for determining cotinine in human body fluids as a measure of passive exposure to tobacco smoke.
A two-day technical workshop was convened November 10-11, 1986, to discuss analytical approaches for determining trace amounts of cotinine in human body fluids resulting from passive exposure to environmental tobacco smoke (ETS). The workshop, jointly sponsored by the U.S. Environmental Protection Agency and Centers for Disease Control, was attended by scientists with expertise in cotinine anal...
متن کاملCombined SPE and HPTLC as a Screening Assay of Urinary Cotinine from Male Adolescents Exposed to Environmental Tobacco Smoke**
Cotinine, as the main metabolite of nicotine, has been determined in urine using solid-phase extraction and the high-performance thin-layer chromatographic (SPE-HPTLC) method. The urine samples were collected from a group of 35 male adolescents which were moderate or significantly exposed to home environmental tobacco smoke (ETS). l-methyl-2-pyrrolidinone was used as the internal standard in th...
