This is a compilation of abstracts of articles identified during the preliminary toxicological evaluation of evidence on the developmental and reproductive toxicity of benzo[a]pyrene (BaP, CAS# 50-32-8). BaP is a polycyclic aromatic hydrocarbon and a component of air pollution. Polycyclic aromatic hydrocarbons are formed as a result of incomplete combustion of organic materials and are ubiquito...

BACKGROUND Because they have chronic airway inflammation, adults with asthma may be particularly susceptible to indoor air pollution. Despite widespread exposure to environmental tobacco smoke (ETS), gas stoves, and woodsmoke, the impact of these exposures on adult asthma has not been well characterised. METHODS Data were used from a prospective cohort study of 349 adults with asthma who unde...

OBJECTIVES The study aimed to review the epidemiological evidence relating environmental tobacco smoke exposure to stroke in never smokers. METHODS The study is similar to our review in 2006, with searches extended to March 2016. RESULTS Twelve further studies were identified. A total of 28 studies varied considerably in design, exposure indices used, and disease definition. Based on 39 sex...

This study was undertaken to determine whether exposure to various indoor pollutants is associated with a higher prevalence of respiratory symptoms, a diagnosis of asthma, or more variable peak flow rates. Four hundred and twenty-six children aged 8-11 years in four junior schools at three locations recorded respiratory symptoms and diagnosis of asthma using the ISAAC questionnaire. Daily peak ...

People assess the quality of the air indoors primarily on the basis of its odors and on their perception of associated health risk. The major current contributors to indoor odorants are human occupant odors (body odor), environmental tobacco smoke, volatile building materials, bio-odorants (particularly mold and animal-derived materials), air fresheners, deodorants, and perfumes. These are most...

Traditionally, the cancer risks associated with radon,environmental tobacco smoke (ETS), and similar indoor residential exposures have been evaluated through either laboratory experiments in rodents or epidemiology studies in people. Laboratory studies have the advantage of being controlled experiments, but their utility as estimators of human risk is limited by the uncertainties of extrapolati...

OBJECTIVE The aim of the study was to assess the effect of environmental pollution and parental tobacco smoking on the occurrence of pseudocroup in children. MATERIAL AND METHODS A questionnaire-study was performed in 345 children with pseudocroup admitted to the ENT Dept between 1997-2007. 116 children had smoking and 229 had non-smoking parents. Both groups were compared with respect to env...

UNLABELLED Reactive oxygenated species (ROS) not only exist in living organisms, they also exist in our environment. Combustion process and photochemical reactions are the major source of environmental ROS, and combustion process produced ROS has been gradually gaining attention in recent years. The purpose of this study is to determine the concentrations of ROS in the mainstream smoke of cigar...

OBJECTIVE To determine the association between environmental tobacco smoke and middle ear disease in pre-school age children. DESIGN A population-based case-control study with verification of disease history and exposure reporting in a subsample. SETTING AND PARTICIPANTS Participants were identified through a population-base probability sample of 1320 first-grade students in 36 schools in C...

OBJECTIVES Environmental tobacco smoke (ETS) has a range of adverse health effects, but its association with dementia remains unclear and with dementia syndromes unknown. We examined the dose-response relationship between ETS exposure and dementia syndromes. METHODS Using a standard method of GMS, we interviewed 5921 people aged ≥60 years in five provinces in China in 2007-2009 and characteri...
