Background: Personal exposure to pollutants is influenced by various outdoor and indoor sources. The aim of this study was to evaluate the exposure of Athens citizens to toluene and xylene, excluding exposure from active smoking.
Methods: Passive air samplers were used to monitor volunteers, their homes and various urban sites for one year, resulting in 2400 measurements of toluene and xylene levels.
Objective: To evaluate the exposure of urban inhabitants to atmospheric benzene in Athens, Greece.
Methods: Fifty non-smoker volunteers from selected occupational groups and their homes were monitored by passive air samplers for six 5-day periods during a year. An activity diary was completed during each sampling period and relevant data were collected by a questionnaire at the beginning of the study.
Background: Occupational risk factors contribute significantly to the development of lung cancer; however, little is known about the extent to which employees are informed of occupational exposure to carcinogenic substances.
Methods: Through a case-control study, we estimated the level of awareness among Greek employees potentially exposed to known carcinogenic substances within various occupational settings.
Results: Only 6.
Study Design: We conducted a cross-sectional, genotyping study of intervertebral disc disease patients and controls.
Objectives: To determine the contribution of COL9A2 and COL9A3 Tryptophan polymorphisms to intervertebral disc disease development in a genetically heterogeneous, Southern European population compared to previous Finnish studies.
Summary Of Background Data: The COL9A2 and COL9A3 genes encode the alpha2 and alpha3 chains of Collagen IX.
