Toxicological Issues of Occupational Exposure in Welding Workers

Occupational UV exposure in French outdoor workers.

OBJECTIVES Occupational ultraviolet (UV) exposure was evaluated in a population-based sample in France. METHODS A random survey was conducted in 2012 in individuals aged 25 to 69 years. The median daily standard erythemal UV dose (SED) was estimated from exposure time and place and matched to satellite UV records. RESULTS A total of 889 individuals were exposed to solar UV with highest dose...

Healthcare workers' perceptions of occupational exposure.

Occupational exposure of workers to 1,3-butadiene.

Researchers from the National Institute for Occupational Safety and Health (NIOSH) conducted an extent-of-exposure study of the 1,3-butadiene monomer, polymer, and end-user industries to determine the size of the exposed workforce, evaluate control technologies and personal protective equipment programs, and assess occupational exposure to 1,3-butadiene. A new analytical method was developed fo...

Occupational Exposure to Styrene Vapor and Determining Risks of Health Consequences in Petrochemical Industry Workers

Introduction: Styrene (C₆H₅CH=CH₂) is known as one of the volatile organic substances produced or used in petrochemical industries. Exposure to this chemical compound can thus lead to respiratory diseases. Therefore, this study aimed to evaluate occupational exposure to styrene vapor and to determine the risks of its health consequences in petrochemical industry workers through a quantitative m...

Occupational exposure to welding gases during three welding processes and risk assessment by SQRCA method

Background: Hazardous chemical agents in the welding operation are a mixture of metal fumes and toxic gases, the inhalation of which causes adverse health effects among welders. The emission of gases in the workplace is a logical cause for concern regarding the potential development of respiratory disease. The aim of the present study was to determine the concentration values of gases discharge...
