The effect of individual pollutants and the period(s) during pregnancy when pollutant levels are likely to have most impact on preterm birth is not clear. We evaluated the effect of prenatal exposure to six common urban air pollutants in the Sydney metropolitan area on preterm birth.
Methods:
We obtained information on all births in metropolitan Sydney between […]

Background:
The project “Assessment and prevention of acute health effects of weather conditions in Europe” (PHEWE) had the aim of assessing the association between weather conditions and acute health effects, during both warm and cold seasons in 16 European cities with widely differing climatic conditions and to provide information for public health policies.
Methods:
The PHEWE project was […]

Background:
N-acetyltransferases (NAT) and glutathione S-transferases (GST) are involved in the metabolism of several ubiquitous chemical substances leading to the activation and detoxification of carcinogenic heterocyclic and aromatic amines. Since polymorphisms within these genes are described to influence the metabolism of ubiquitous chemicals, we conducted the present study to determine if individuals with self-reported chemical-related sensitivity […]

Background:
Several countries are discussing new legislation on the ban of smoking in public places, and on the acceptable levels of traffic-related air pollutants. It is therefore useful to estimate the burden of disease associated with indoor and outdoor air pollution.
Methods:
We have estimated exposure to Environmental Tobacco Smoke (ETS) and to air pollution in never smokers […]

Background:
This is a community comparison study that examines persons living in a subdivision exposed to petroleum products and mercury.
Methods:
We compared their health status and questionnaire responses to those living in another community with no known exposures of this type.
Results:
Pristane house dust among the exposed homes was higher than in the comparison communities. The exposed subdivision […]

Background:
In the Arctic, polar bears (Ursus maritimus) bio-accumulate mercury as they prey on polluted ringed seals (Phoca hispida) and bearded seals (Erignathus barbatus). Studies have shown that polar bears from East Greenland are among the most mercury polluted species in the Arctic. It is unknown whether these levels are toxic to liver and kidney tissue.
Methods:
We […]

Background:
Asthma prevalence is lower in less developed countries and among some recent immigrant populations in the US, but the reasons for this are not clear. One possibility is that early childhood infections are protective against asthma.
Methods:
We surveyed Asian immigrant children (n=204; age 4-18) to assess the relationship between asthma and native or foreign place […]

Dietary POP exposure have shown negative effects on sperm motility and sperm chromatin integrity, as well as an increased proportion of Y-chromosome bearing sperms. However, it has been suggested that in epidemiological studies investigating persistent organochlorine pollutant (POP)-toxicity, other pollutants occurring simultaneously may carry an increased risk of effects, which may obscure a clear interpretation […]
