BACKGROUND The evaluation of infant meconium as a cumulative matrix of prenatal toxicant exposure requires comparison to established biomarkers of prenatal exposure. METHODS We calculated the frequency of detection and concentration of tobacco smoke metabolites measured in meconium (nicotine, cotinine, and trans-3'-hydroxycotinine concentrations) and three serial serum cotinine concentrations...

GOAL Monitoring of exposure of school children to ETS as indicator of enforcement of ban of smoking in public places as tobacco control measure in the Federation of BiH. METHODS Analysis of s...

Studies of the effects of environmental exposures on domestic and wild animals can corroborate or inform epidemiologic studies in humans. Animals may be sensitive indicators of environmental hazards and provide an early warning system for public health intervention, as exemplified by the iconic canary in the coal mine. This article illustrates the application of animal sentinel research to eluc...

The present study investigated the association between reported parental smoking and exhaled nitric oxide fraction (F(eNO)) in young children. In total, 78 children (24 females, mean age 51.3 weeks) were recruited. Fourteen lived with one smoking parent and eight with two smoking parents. F(eNO) was measured using the modified single-breath technique. Mean+/-sd F(eNO) levels were 33.0+/-18.9, 3...

OBJECTIVES Students, faculty, and staff at a Pacific Northwest public university were surveyed one year after enactment of a smoke-free campus policy. Objectives were to assess levels of support for a smoke-free campus, ascertain exposure levels to outdoor tobacco smoke, and identify correlates of policy support. METHOD A 2013 Web-based survey included 5691 students (response rate 26%) and 20...

BACKGROUND Environmental tobacco smoke (ETS) exposure is a well-known health hazard for children. Poor urban children may be at increased risk of exposure from nonparental sources of tobacco smoke. The unique problems of ETS exposure in urban children have previously not been well-defined. OBJECTIVES This study was conducted: 1) to identify the sources of ETS exposure for children attending a...
