While the effects of IAP on health have been studied extensively in many countries, especially in developed countries, but very limited in Vietnam. There are studies reported about the IAP level in complex building in urban area [16], kitchen room at rural area [17], and traffic mod[r]

Particles
Particles, as noted above, can provide an exposure pathway for SVOCs, but they also can present a serious health risk on their own. They range in size from very small (0.001 μm to 10 μm), which can remain in the air for a long time, up to relatively large (100 μm), which quic[r]

Sometimes in valuation exercises two different methods can be used. This gives the opportunity to researchers to compare the results obtained and test for the reliability of the valuation. Belhaz (2003) employed contingent valuation and hedonic price methods to estimate the benefits of clean [r]

One of the main difficulties in air pollution management is to determine the quantitative relationship between ambient air quality and pollutant sources. Source apportionment is the process of identification of aerosols emission sources and quantification of the c[r]

Assuming equal radon emanation potentials under dwellings with base- ment, slab-on-grade, and crawlspace substructures, highest indoor radon concentrations are expected to occur in those constructed on basements. This is so because basements have the highest surface area in contact with the g[r]

Duct systems in residences can cause or contribute to indoor air con- tamination problems. Historically, ducts (both supply and return) were con- structed of galvanized steel. Increasingly, ducts are being fabricated from fiberglass materials. These include duct board, which is fashion[r]

This paper presents the determination method, occurrence and distribution of phthalates in indoor dust and indoor air samples collected in Hanoi, Vietnam. The optimal method has met the requirement to accurately identify phthalates in environmental samples.

Airborne microbial allergens are indoors and outdoors. Generally, the outdoor levels are greater than the indoor levels. Even when the outdoor levels exceed the indoor levels, identification of the indoor and outdoor microbial allergens by genus and species is a means for determ[r]

The most typical air pollutants including PM10, CO, SO2, NOx are monitored at different sites indoor (basement, shopping malls) and outdoor (ambient air) of several complex buildings which are used for different purposes of resident, office, and shopping malls in Hanoi. The results show that the ind[r]

For risk assessment, epidemiologic studies offer two obvious advantages over experimental studies. Firstly, since the studies are done in the species of ultimate interest, the human, the difficult problem of interspecies extrapolation is finessed. Secondly, most epidemiologic studies are done at lev[r]

c. Model Uncertainty
Model uncertainty arises when more than one conceptual or mathematical model can be used to address the exposure scenario. The EPA advises that a qualitative discussion be made to address the model acceptance by the scientific community and its applicability to the specific pr[r]
