“…Fang et al [8] found that the total PAH concentration in smoke from biomass burning ranged from 7 to 46 ng/m 3 . The highest value of B(a)P was measured at 3 ng/m 3 while the lowest was at the same site 0.1 ng/m 3 . These values are comparable to those measured at street level in urban centres such as Hong Kong.…”

As part of the air quality monitoring and assessment, emissions from the open air burning of waste and biomass have proven important sources of impact on the population exposure. The emissions of a variety of air pollutants from different types of open-air burning have been evaluated. Simple model estimates are used to estimate the impact in areas downwind from backyard burning. Different models have been used to estimate the importance of impact and the reasons for odours detected downwind from waste dumping areas.Data from Cairo and other major cities have been used to estimate the impact of emissions from agricultural waste burning. In several urban areas especially in developing countries the contribution to the PM exposure has been demonstrated to range between 30 and 50% dependent upon weather conditions. The design and application of combined monitoring programmes and models may be part of the systematic evaluation of impacts and optimal control of the sources.

“…Not infrequently, residents also report physical symptoms which they attribute to dumpsite emissions. Environmental monitoring, while occasionally demonstrating significant off site exposures (particularly when drinking water contamination has occurred), more frequently shows only low (part-per-billion) levels of airborne contaminants-levels insufficient to cause acute or even subacute symptoms by known toxicologic mechanisms (2). In an effort to understand this apparent discrepancy between symptom reporting and low-level exposure potential, the issue of "environmental worry" has been examined epidemiologically and shown to be related to symptom reporting, even in neighborhoods distant from hazardous waste sites (3).…”

Retrospective symptom pralence data, coec from over 2000 adult respondents living near three different hazrds waste sites, were analyzed with respect to both self-reported "environmental worry" and frequency of perceiving environmental (particularly petrochemical) odos Sigifnt positive relationships were observed between the prevalence of several symptoms (headache, nausea, eye and throat irritation) and both frequency of odor perception and degree of worry. Headaches, for example, showed a prevalence odds ratio of 5.0 comparing respondents who reported noticing environmental odors frequently versus those noticing no such odors and 10.8 comparing those who described themselves as "very worried" versus "not iworied" aboute i conditiosin their neighborhood. I tionofrespondents who ascribed their environnmental worry to illness in themselves or in family members did not materially affect the strength ofthe observed associations. In addition to their independent effects, odor perception and environmental worry exhibited positive interaction as determinants of symptom prevalence, as evidenced by a prevalence odds ratio of 38.1 comparing headaches among the high worry/frequent-odor group and the no-worry/no-odor group. In comparison neighborhoods with no nearby waste sites, environmental worry has been found to bea with symptom occurrence as well. Potential explanations for these observations are presented, including the possibility that odors serve as a sensory cue for the manifestation of stress-related illness (or heightened awareness of underlying symptoms) among individuals concerned about the quality of their neighborhood environment.

“…Contaminants can also be transported away from a site through the subsurface environment. Most research on the subsurface migration of VOC has focused on aqueous transport (Bennett, 1986;Roy and Griffin, 1987). Direct exposures due to contaminated ground water occur when the water is ingested.…”
