Indoor Air Pollution: Volatile Organic Compounds In Non-Industrial Microenvironments In Thailand, Maneerat Ongwandee
Indoor Air Pollution: Volatile Organic Compounds In Non-Industrial Microenvironments In Thailand, Maneerat Ongwandee
Applied Environmental Research
This paper was intended to review literature related to indoor air quality research conducted in Thailand during the past decade. The content was devoted to a certain indoor pollutant group which were volatile organic compounds (VOCs). VOCs were present indoors to a wide range of concentrations with a variety of chemical species. This paper discussed the VOC investigations designated to non-industrial microenvironments, which included workplaces, residences, and mass transit. Typically, levels of VOCs found in the nonindustrial microenvironments were significantly less than those found in industries. Although concentrations of VOCs in the non-industrial microenvironments may not be high enough to …

Gasoline station is a common source of volatile organic compounds (VOCs) emissions around its perimeter. In order to conduct a monitoring of the VOC's emission, measurements of biological markers of blood benzene, toluene, ethylbenzene and xylene (BTEX) in gasolinestation workers are recommended. The purposes of this study were to evaluate exposure risk ratio (110 gasoline station workers from 11 gasoline stations in Bangkok Metropolitan area compared to 10 office workers in the same station as control group) and to determine the relations between blood BTEX and biological parameters of the gasoline workers. Results showed that blood BTEX levels of gasoline …
A Preliminary Study On Total Volatile Organic Compound (Tvoc) Concentrations In Public Buses In Bangkok, Manunart Feungpean, Sopa Chinwetkitvanich
A Preliminary Study On Total Volatile Organic Compound (Tvoc) Concentrations In Public Buses In Bangkok, Manunart Feungpean, Sopa Chinwetkitvanich
Applied Environmental Research
Recently, some new buses made in China have been purchased to give the transportation services in Bangkok due to their lower price. Unfortunately, volatile air pollutants emitted from material in new motor vehicles was little concern. The objective of this study was to conduct a preliminary survey of total volatile organic chemicals (TVOCs) in the cabins of some new buses used in public transportation in Bangkok. TVOCs was monitored in the air-condition buses running within Bangkok area under actual driving condition. Three buses were randomly sampled from three routes, i.e. the route number 8, 539 and 542. All of sampling …
