Health Risks Assessment from Cured-in-Place Pipe Lining Fugitive Styrene Emissions in Laterals

Styrene Resin Used in Cured in Place Pipe Rehabilitation May Have a Significant Localized Ecotoxicity, Despite Fast General Biodegradation

The purpose of this study was to establish the dynamics and kinetics of the aromatic hydrocarbons breakdown in aqueous environment. The investigated compounds were: benzene, toluene, m-xylene, p-xylene and styrene. These substances even in low concentrations threaten surface waters taken for municipal purposes because of their toxicity and also mutagenic and tumorigenic properties. The study wa...

Assessment of air pollution in exercise centers and health risks

Background: In recent years, Tehran has faced major problems with air pollution for many reasons, and this issue has become a critical point in most of the days. However, less attention has been paid to the indoor air pollutants in exercise centers and their possible health effects. In this research, it was tried to briefly describe the characteristics and chemical composition of the aerosols p...
