Health effects among refrigeration repair workers exposed to fluorocarbons.

Cardiotoxicity of Freon among refrigeration services workers: comparative cross-sectional study

BACKGROUND Freon includes a number of gaseous, colorless chlorofluorocarbons. Although freon is generally considered to be a fluorocarbon of relatively low toxicity; significantly detrimental effects may occur upon over exposure. The purpose of the present study is to investigate whether occupational exposure to fluorocarbons can induce arterial hypertension, myocardial ischemia, cardiac arrhyt...

Studies on battery repair and recycling workers occupationally exposed to lead in Karachi.

UNLABELLED OBJECTIVE. The present study was carried out to investigate the effects of occupational lead exposure on the hematological and biochemical parameters in occupationally exposed and non exposed inhabitants of Karachi. MATERIAL AND METHODS. In 100 lead exposed subjects recruited from automobile workshops, lead battery repair and recycling units located in Karachi and in 100 control subj...

Evaluation of Extremely Low Frequency (ELF) Electromagnetic Fields and Their Probable Relationship with Hematological Changes among Operators in Heavy Metal Industry

Introduction: It is important that biological and health effects from the induction of currents and fields in the body by extremely low frequency (ELF) fields are fully explored to determine the effects produced at the molecular, cellular and organ levels. The objective of this study was to evaluate the intensity of ELF electromagnetic fields and its probable relationship with hematological cha...

Effects of Dietary Green Tea Polyphenol Supplementation on the Health of Workers Exposed to High-voltage Power Lines

Measurement of DNA repair deficiency in workers exposed to benzene.

We hypothesize that chronic exposure to environmental toxicants can induce genetic damage causing DNA repair deficiencies and leading to the postulated mutator phenotype of carcinogenesis. To test our hypothesis, a host cell reactivation (HCR) assay was used in which pCMVcat plasmids were damaged with UV light (175, 350 J/m2 UV light), inactivating the chloramphenicol acetyltransferase reporter...
