Assessment of indoor air organic pollutants and its impact on experimental animals
Outdoor Air Pollution, Indoor Air Pollution, Suspended Particulate Matter, Polycyclic Aromatic Hydrocarbons, Volatile Organic Compounds, Benzene.
Indoor air quality (IAQ) has become a public health issue of increasing concern during the last decades. Most people spend an average of 90% of their time within enclosed buildings (living, working and studying). Indoor air pollutants impact human health, comfort and productivity. IAQ can be affected by volatile organic compounds (VOCs), Suspended Particulates Matter (SPM), polycyclic aromatic hydrocarbons (PAHs) that can induce adverse health conditions. There are many sources of indoor air pollution in residential environment include combustion sources such as oil, gas, kerosene, coal, wood, and tobacco products; building materials and furnishings, products for household cleaning and maintenance, central heating and cooling systems and humidificationdevices beside outdoor air pollution. Previous studies showed that indoor environment is highly polluted and sometimes pollution can be at its worst inside homes. However, in Egypt there is a lack in the detail information about the levels of organic compounds such as VOCs and PAHs and the magnitude of the existing air pollution.This study contains two main sections. The first one concerned about the indoor and outdoor air quality of fourhomes in Helwan city and its impact on the indoor environment this includes monitoring of SPM, VOCs, and PAHs in both indoor and outdoor air in the investigated sites. The second section concentrated on measuring the effect of different concentrations of Benzene (organic pollutant) on the level of Glutathione, Nitric oxide, Lipid peroxidation, liver and kidney functions of rats.In addition, the levels of indoor and outdoor air pollutants were compared. The study findings were compared with different standard guidelines.
