Abstract
BTEX is the commonly used term for a group of toxic compounds (benzene, toluene, ethyl benzene, ortho-xylene and meta- and para-xylene), some of which, most notably benzene, are known carcinogens. The aim of this study is to measure the BTEX levels both inside and outside the homes of 352 one-year old children from the Valencia cohort of the INMA study (Spain) and to analyze the determinants of these levels. Passive samplers were used to measure BTEX levels during a 15day period and a questionnaire was administered to gather information on potentially associated factors (sociodemographics, residential conditions, and lifestyle). The average concentrations of benzene, toluene, ethyl benzene, ortho-xylene, and meta- and para-xylene were 0.9, 3.6, 0.6, 0.6, and 1.0mug/m(3), respectively. On average, the indoor levels of all the compounds were approximately 2.5 times higher than those observed outdoors. Factors associated with higher BTEX concentrations inside the home were being the child of a mother of non-Spanish origin, living in a house that had been painted within the last year, living in an apartment, and not having air conditioning. Higher outdoor concentrations of BTEX depend on the residence being situated in a more urban zone, being located within the city limits, having living in a building with more than one story, residing in an area with a greater frequency of traffic, and the season of the year in which the sample was taken. The data thus obtained provide helpful information not only for implementing measures to reduce exposure to these pollutants, but also for evaluating the relation between such exposure and possible health risks for the children in the cohort.

Abstract
Studies on health effects of air pollutants ideally define exposure through the collection of air samples in the participants' homes. Concentrations derived from these samples are then considered as an estimate for the average concentration of air pollutants in the homes. Conclusions drawn from such studies therefore depend very much on the validity of the measured air pollution concentrations. In this paper we analysed repeated BTEX and NO(2) measurements with a time period of several months lying between the two conducted home visits. We investigated the variability of their concentrations over time by determining correlation coefficients and calculating within- and between-home variances. Our population consisted of 631 homes of participants from two cohort studies within the framework of the German study on Indoor Factors and Genetics in Asthma. Air pollutants were measured using passive samplers both indoors and outdoors. The measured BTEX concentrations were poorly correlated, with Pearson's correlation coefficient r ranging from -0.19 to 0.27. Additionally, a considerable seasonal effect could be observed. A higher correlation was found for the NO(2) concentrations with r ranging between 0.24 and 0.55. For the BTEX, the between-home variance was bigger than the within-home variance, for NO(2) both variances were of about the same order. Our results indicate that in a setting of moderate climate like in Germany, the variability of BTEX and NO(2) concentrations over time is high and a single measurement is a poor surrogate for the long-term concentrations of these air pollutants.

Abstract
Indoor and outdoor concentration levels of 21 carbonyl compounds and five BTEX (benzene, toluene, ethylbenzene and xylenes) were measured in four hospitals of Guangzhou from 2nd January to 20th March 2004. Samples were collected in five consecutive daytimes for each hospital. Among most of the samples, acetone was the most abundant carbonyl, followed by acetaldehyde, 2-butanone or formaldehyde. Toluene was the most abundant BTEX and the others were at similar levels. The relatively higher acetone concentrations might have resulted from the high level of background in Guangzhou area due to emission of the factories and LPG-fuel vehicles, and also for the special weather conditions during sampling time. The high concentration of acetaldehyde, which was even higher than that of formaldehyde, might be resulted from the wide use of ethanol in hospital. The partial oxidation of ethanol may form acetaldehyde. The indoor concentrations of carbonyls and BTEX were found a little higher than their outdoor counterparts with only a few exceptions, which showed the anthropogenic sources for these compounds. The low correlations between most carbonyls and BTEX concentrations might be caused by their complex sources. Finally, the human exposure levels of formaldehyde and acetaldehyde in hospitals are discussed.

Abstract
OBJECTIVE: An analysis of airborne nicotine measurements collected in 49 low-income, multi-unit residences across the Greater Boston Area. METHODS: Nicotine concentrations were determined using passive monitors placed in homes over a one-week sampling period and air exchange rates (AER) were sampled using the perfluorocarbon tracer technique. Residents were surveyed through a questionnaire about smoking behaviour and a visual inspection was conducted to collect information on housing characteristics contributing to secondhand smoke (SHS) exposure. Using a mass balance model to account for the air exchange rate, volume of the home and sorption and re-emission of nicotine on indoor surfaces, the effective smoking rate (SR(eff)) was determined for each residence. RESULTS: Nicotine levels ranged from the limit of detection to 26.92 microg/m(3), with a mean of 2.20 microg/m(3) and median of 0.13 microg/m(3). Nicotine measurements were significantly associated with the number of smokers in the household and the number of cigarettes smoked in the home. The results of this study suggest that questionnaire reports can provide a valid estimate of residential exposure to tobacco smoke. In addition, this study found evidence that tobacco smoke contamination in low-income housing developments is not limited to homes with smokers (either residing in the home or visiting). The frequent report of tobacco smoke odour coming from other apartments or hallways resulted in increased levels of nicotine concentrations and SR(eff) in non-smoking homes, suggestive of SHS infiltration from neighbouring units. CONCLUSION: These findings have important implications for smoking regulations in multi-unit homes and highlight the need to reduce involuntary exposure to tobacco smoke among low-income housing residents.

Abstract
Indoor exposures at home, environmental tobacco smoke (ETS) and mould/dampness adversely affect respiratory health of children. Disturbi Respiratori nell'Infanzia e Ambiente in Sardegna (DRIAS) (Respiratory Symptoms in children and the Environment in Sardegna, Italy) aims at relating the prevalence of respiratory and allergic symptoms to indoor exposures in Sardinian children. DRIAS, a cross-sectional investigation of respiratory symptoms/diseases, used a modified version of ISAAC questionnaire, included 4122 children attending 29 primary schools in the school year 2004-2005. If both parents smoke the prevalence for current wheeze and current asthma is almost doubled in comparison with never smokers, for persistent cough and phlegm a role is suggested when only mother smokes. Among mothers smoking in pregnancy, the prevalence of current wheeze and current asthma is increased. Exposure to ETS and family atopy have a joint effect resulting in an almost tripling of prevalence for current wheeze and more than four times for current asthma. Exposure to "dampness" (mould or dampness) both during the first year of life and currently is associated with increased prevalence of current wheeze, persistent cough or phlegm and current rhino-conjunctivitis; if exposure is only during the first year of life a doubling or more of prevalence is observed for current wheeze, current asthma, and persistent cough or phlegm. DRIAS results add evidence to the causal role of childhood exposure to ETS in the development of respiratory symptoms (cough, phlegm, and wheezing) and asthma. The joint effect of ETS and family atopy is corroborated. The results strengthen the evidence for a causal association between "dampness" and respiratory health, pointing to its possible independent role in causing asthma, a long-lasting exposure entails a doubled prevalence for both asthmatic and bronchitis symptoms.

Abstract
BACKGROUND: Secondhand smoke accounts for a considerable proportion of deaths due to tobacco smoke. Although the existing laws ban indoor smoking in public places in Sri Lanka, the level of compliance is unknown. METHODS: Fine particulate matter (PM(2.5)) levels in 20 public places in Colombo, Sri Lanka were measured by a PM monitor (Model AM510-SIDEPAK Personal Aerosol Monitor). Different types of businesses (restaurants, bars, cafes, and entertainment venues) were selected by purposive sampling. Only the places where smoking was permitted were considered. RESULTS: The average indoor PM(2.5) ranged from 33 to 299 microg/m(3). The average outdoor PM(2.5) ranged from 18 to 83 microg/m(3). The indoor to outdoor PM(2.5) ratio ranged from 1.05 to 14.93. In all venues, indoor PM(2.5) levels were higher than the Sri Lankan ambient PM(2.5) standard of 50 microg/m(3). All indoor locations had higher PM(2.5) levels as compared to their immediate outdoor surroundings. CONCLUSION: The study highlights the importance of improving ventilation and enforcing laws to stop smoking in public places.

Abstract
The growth of the bacterial community harbored in indoor drinking water taps is regulated by external environmental factors, such as indoor temperature. However, the effect of indoor heating on bacterial regrowth associated with indoor drinking water taps is poorly understood. In the present work, flow cytometry and community-level sole-carbon-source utilization techniques were combined to explore the effects of indoor heating on water bacterial cell concentrations and community carbon metabolic profiles in building tap pipes during the winter season. The results showed that the temperature of water stagnated overnight ("before") in the indoor water pipes was 15-17 degrees C, and the water temperature decreased to 4-6 degrees C after flushing for 10 min ("flushed"). The highest bacterial cell number was observed in water stagnated overnight, and was 5-11 times higher than that of flushed water. Meanwhile, a significantly higher bacterial community metabolic activity (AWCD590nm) was also found in overnight stagnation water samples. The significant "flushed" and "taps" values indicated that the AWCD590nm, and bacterial cell number varied among the taps within the flushed group (p

Abstract
BACKGROUND: To evaluate secondhand smoke (SHS) contribution on indoor Particulate Matter (PM) concentrations due to a single smoked cigarette in a real exposure scenario. METHODS: Total Suspended Particles (TSP) and sizes =10 (PM(10)), =4 (PM(4)), =2.5 (PM(2.5)), and =1 mum (PM(1)) levels were measured before, during and after smoking in an enclosed smoke-free environment. The measurement was stopped 30 minutes after extinguishing the cigarette, to focus the monitoring just on SHS. RESULTS: PM(1) concentrations dramatically increased during and 30 minutes after smoking (mean values: 21.1, 1544.0 and 279.0 mug/m3 before, during and after, respectively), while the other PM fractions remained almost unchanged. CONCLUSIONS: This experiment implies that smoking even one cigarette produces important indoor air pollution which may considerably increase individual exposure to ultrafine particles, and, consequently, pose a serious threat to health.

Abstract
AIM OF THE STUDY: There are International and National standards that requires hospitals and health premises to be smoke-free. According to recent data from Italy and other European Countries, smoking is a widespread habit in hospitals. To get smoke-free hospitals in an Italian region, we have adopted the European Code for smoke-free hospitals, which sets standards and provides instruments for its implementation. According to the Code, whenever possible, each step towards a smoke-free hospital, should be shared by all staff. As a mean for achieving this goal, in our region the certification of single units as smoke-free units has been chosen. For getting the certification, besides implementing the Code, we planned to use ETS (Environmental Tobacco Smoke) monitoring, as ETS should not be present in hospitals. As a marker of ETS we have chosen Particulate Matter (PM), as it can easily be measured in real-time with a portable instrument and, when other even outdoor--sources of combustion can be ruled out, it is an accurate detector of cigarette smoke. Here the first experience of measuring PM in hospitals for monitoring ETS and certificating smoke-free health premises, is described. MATERIALS AND METHODS: PM measurements were carried out without any previous notification in different areas of two Network hospitals of the Veneto Region, during a single working day. A real time laser-operated aerosol mass analyser was used. Several classes of PM (PM1, PM2.5, PM7, PM10, TSP Total Suspended Particles) were measured. RESULTS: Outdoor PM levels were found to be repeatedly lower than the annual official limits of 65 mcg/m3 and around the 24 hour official limits of 15 mcg/m3 [15 to 20 mcg/m3, with an overall mean (+/-SD) of 17.8 (1.9)] throughout the whole day. Very good indoor air quality was found in the operating theaters and isolation department, where PM2.5 concentrations were much lower than outdoor levels [1.6 (0.9) and 5.9 (0.6) mcg/m3, respectively]. No increase in PM pollution was found in the surveyed medical offices, halls and waiting rooms where smoking was positively forbidden [PM2.5 concentrations of 14.8 (2.2) and 12.9 (1.1) mcg/m3] except in a medical office and in two coffee rooms for staff only where high PM levels were recorded [PM2.5 58.7 (29.1), 27.0 (10.6) and 107.1 (47.8) mcg/m3] and an offence of smoking restrictions could be proved. CONCLUSIONS: The measurement of PM in hospital for monitoring ETS proved to be both feasible and sensible. PM measurements with a portable instrument can be used both for controlling the compliance with rules or chosen standards and for educating staff about smoking related hazards, thus gaining consensus for the implementation of the tobacco control policy. In our experience, PM measurement can be used as an aid inside all actions designed by the European Code for smoke-free hospitals.

Abstract
BACKGROUND: To date, Lebanon has failed to enact comprehensive clean indoor air laws despite ratification of the Framework Convention on Tobacco Control (FCTC), which calls for the protection of non-smokers from exposure to secondhand tobacco smoke (SHS). Complicating the problem of SHS exposure in Lebanon is the widespread use of the tobacco water-pipe. While most research on SHS has involved cigarette smoking as a source of emissions, other sources, including tobacco water-pipes, may be an important contributor. METHODS: PM(2.5) concentrations (microg/m(3)) were measured in a sample of 28 public venues located in six major Lebanese cities. Active smoker density (number of smokers/100 m(3)) was calculated for both water-pipe and cigarette smokers. Venues were then categorised as having higher density of water-pipe smokers or higher density of cigarette smokers, and resultant emission levels were compared between the two groups. RESULTS: Cigarette and water-pipe smoking was observed in 14 venues, while cigarette smoking only and water-pipe smoking only were found in 12 venues and one venue, respectively. Among all smoking-permitted venues, the mean PM(2.5) concentration was 342 microg/m(3). Venues with a higher density of water-pipe smokers (n =14) showed a similar median PM(2.5) concentration (349 microg/m(3)) compared with venues with a higher density of cigarette smokers (n =13; 241 microg/m(3); p=0.159). The mean PM(2.5) concentration in the single venue with a voluntary smoke-free policy was 6 microg/m(3). CONCLUSIONS: Despite ratification of the FCTC in 2005, both cigarette and water-pipe smoking are commonly practised in enclosed public places throughout Lebanon, leading to unsafe levels of indoor particulate pollution. Smoke-free policies are needed in Lebanon to protect the public's health, and should apply to all forms of tobacco smoking.
