Traffic-related Air Pollution (TRAP), Air Quality Perception and Respiratory Health Symptoms of Active Commuters in a University Outdoor Environment

Air pollution is a global environmental problem that affects the population. This work demonstrates the perception of air quality by the population of the urban area of the municipality of Acapulco, Guerrero, Mexico. To meet the objective, a survey of 36 questions was applied to a sample of 382 people living in the main crossing points of vehicles, where there is more traffic and more severe pollutant concentration problems. We decided to apply the grouping method within a radius of 500 m around the selected intersections, where 95% of the respondents are aware that the air they breathe has a certain degree of contamination.

The Impact

We should be concerned about the impact of indoor air quality on health because in the United States, people spend most of their time indoors. While earlier studies have characterized the odds of developing illness based on the home environment, they have not investigated the behaviors that can ameliorate the negative effect of indoor, outdoor, and behavioral sources. The purpose of this study was to 1) investigate the contributions of indoor, outdoor, and behavioral sources of pollutants on health symptoms, and 2) to identify the behaviors that can worsen or mitigate the number of health symptoms. Data came from two surveys (n=83,284) and include questions on home conditions, outdoor conditions, occupants’ behaviors, and health symptoms. I used negative binomial regression and identified that demographics and outdoor characteristics explain 2% of the variability in health symptoms, and maintenance behaviors explain 8% of the variability in health symptoms. Next, structural equation modeling (SEM) was used to examine the behaviors that can mitigate or worsen the number of health symptoms. The results show that maintenance issue such as mold result in significantly more health symptoms (β = .12, p <.001). and factors such as leaks, and frequent long shower may result in an increase in mold. Leaks may cause water stains (β = .39, p <.001) which could lead to molds (β = .47, p <.001). While frequent long shower can result in an increase in mold (β = .05, p <.001), the use of a bathroom exhaust during shower may help to reduce molds (β = -.04, p <.001). In terms of personal behaviors, the presence of carpet (β = .08, p <.001), and smoking also result in an increase in surface dust (β = .17`, p <.001) but frequent vacuuming could mitigate the impact of surface dust on health symptoms (β = -.12, p <.001). Home occupants who live near environmental hazards are also likely to use air purifier (β = .03, p <.001); however, air purifier is associated with more health symptoms (β = .05, p <.001). Based on the findings, it is recommended that home occupants engage in periodic maintenance to prevent issues such as leaks from escalating to molds, regular vacuuming to reduce the accumulation of surface dust. Regarding air purifier, it could be that participants who experienced more health symptoms were more likely to use an air purifier. However, some air purifiers are sources of ozone, therefore home occupants should err on the side of caution when it comes to air purifier (Britigan et al., 2006; Cestonaro et al., 2017).

The Impact

AbstractThe indoor environment is a major source of human exposure to pollutants. Some pollutants can have concentrations that are several times higher indoors than outdoors. Prolonged exposure may lead to adverse biologic effects, even at low concentrations. Several studies done in Malaysia had underlined the role of indoor air pollution in affecting respiratory health, especially for school-aged children. A critical review was conducted on the quantitative literature linking indoor air pollution with respiratory illnesses among school-aged children. This paper reviews evidence of the association between indoor air quality (IAQ) and its implications on respiratory health among Malaysian school-aged children. This review summarizes six relevant studies conducted in Malaysia for the past 10 years. Previous epidemiologic studies relevant to indoor air pollutants and their implications on school-aged children’s respiratory health were obtained from electronic database and included as a reference in this review. The existing reviewed data emphasize the impact of IAQ parameters, namely, indoor temperature, ventilation rates, indoor concentration of carbon dioxide (CO

Factors Associated

Cold, damp and mouldy housing arises from the degradation of the housing stock over time due to weathering and a lack of maintenance. Living in such houses is associated with many adverse impacts on human health, especially for those with existing health issues. This paper presents a systematic review, using the PRISMA protocol, consisting of an exploratory analysis of housing-related risk factors associated with respiratory disease. The review consisted of 360 studies investigating 19 risk factors associated with respiratory conditions. Each fall into one of four categories, namely, (1) outdoor environment-related factors; (2) indoor air pollution-related factors; (3) housing non-structure-related factors; or (4) housing structure-related factors. The results show that effects of poor housing conditions on occupants’ respiratory health is a growing research field, where poor indoor air quality, mainly due to a lack of adequate ventilation, was found to be the most influential risk factor. Usage of solid fuel and living in an urban area without a pollutant-free air filtration system are the main risk factors related to inadequate ventilation. Therefore, an adequate and reliable ventilation system with air-infiltration was considered to be the main mitigation solution to improve indoor air quality. It is suggested that government organisations and health practitioners could use the identified risk factors to measure the healthiness of existing dwellings and take measures to improve existing conditions and develop regulations for new housing construction to promote the healthy home concept. Further research is needed for risk mitigation strategies to reduce the respiratory health burden attributed to housing.

Ozone (O3 ) is the second prominent air pollution in Malaysia. The annual variation of ozone concentration depends upon several conditions such as the sources of its precursor, the land use type and meteorological parameter. This study aims to understand the trends and issues of transformation characteristics of O3 in 4 urban area (Shah Alam, Kajang, Johor Bahru and Kota Bharu) during specific critical conversion time (CCT) as well as to introduce the critical transformation time (CTT) of O3 in 4 selected continuous air quality monitoring stations (CAQMS) from the year 2000 to 2011. The identification of CTT for O3 formation was identified occurring between 8.00 a.m and 11.00 a.m., and the O3 uni-modal peaks usually after CTT at approximately between 12.00 p.m and 4.00 p.m. The results indicated that the CTT of O3 in the Kota Bharu is slightly earlier occurring between 8.00 a.m to 10.00 a.m whereas Shah Alam, Kajang and Johor Bahru the CTT later occurring between 10.00 a.m to 11.00 a.m. Only Kota Bharu recorded data was below 100 part per billion volume (ppbv), while Shah Alam, Kajang and Johor have recorded exceedances above 100 ppbv. This research elucidates that CTT is adequate to control ozone concentration. Ozone might exceed Recommended Ambient Air Quality Guideline (RMAAQC) unless nitrogen emissions are adequately managed, due to the detrimental effects for those who are at risk of respiratory health problems resulting from air pollution.

INTRODUCTION. Air pollution is the leading environmental problem in Pancevo. Sources are traffic, home heating, industry, land fields, and street dust. Air pollution has harmful effect on population health, particularly the health of children. OBJECTIVE. To estimate school-children?s respiratory health in Pancevo. ??THOD. The air quality in Pancevo and Vrsac was measured by standard methods. The health condition was tested by anthropometric, clinical examination and spirometric measures in school children of II-V classes of three primary schools in Pancevo and one in Vrsac, in 2002. Data from 1136 children were analyzed: 796 in Pancevo, and 340 in Vrsac. Parents answered the questions in questionnaires: non standardized questionnaire about children?s health, social status and smoking in the family, questionnaire about pregnancy, physical activity and standardized ISAAC questionnaire about asthma and eczema. RESULTS. During the 2002/2003 heating season in Vrsac, concentrations of SO2 and soot were less than limit concentrations of emission and significantly less than in Pancevo air. Results showed that the asthma, wheezing during physical activity (p<0.05), dry cough at night (p<0.001), cold and tonsilo-pharyngitis (p?0.05) were significantly more frequent in girls from Pancevo than girls from Vrsac. Morning cough (p<0.05) and wheezing (p<0.01) was significantly more frequent in boys from Pancevo than boys from Vrsac. Children from Pancevo were much higher than children in Vrsac. Less vital capacity (p<0.05) and mild restriction (p<0.001) were more often in children from Pancevo than children in Vrsac. CONCLUSION. Our investigation confirmed that children from Pancevo had problems with respiratory health more often than children in Vrsac.

Background: Indoor air pollution (IAP) constitutes a major global public health problem requiring increasing efforts in research and policymaking that may have special significance for elderly that are likely to spend most of their day indoors and appear to be particularly susceptible to adverse effects of chemical pollutants and bio-contaminants. Yet, evidence existing on the effects of IAP in elderly is scanty. The Geriatric study in Europe on health effects of air quality in nursing homes (GERIE) study aimed to assess health effects of major indoor air pollutants and thermal conditions in elderly (> 70 years) living stably in nursing homes (NH) across Europe. Respiratory effects were particularly considered as airways and lung constitute the first target of air pollutants. Objectives: We describe here the rationale and the methods of the GERIE Study. Methods: 8 nursing homes were randomly selected in 7 European countries. Twenty individuals were randomly selected in each nursing home. Major indoor and outdoor air chemical pollutants (PM10, PM2.5, PM0.1, formaldehyde, NO2; O3, VOC, CO2) and bio-contaminants (moulds, allergens) were assessed objectively with standardized procedures. Major health status indicators were assessed through a standardized questionnaire, non-invasive clinical tests and blood and urine biomarkers as well as saliva for ADN. Results: The GERIE study has given the opportunity to publish two reviews on respiratory health effects of indoor and outdoor air pollution in elderly. In addition it has provided the inventory of air quality and thermal conditions in 50 nursing homes across Europe and data on respiratory health status in 600 elderly aged 82 years in mean. Major future results will include the relationships between NH environment and health in elderly. Conclusions: The main long-term purpose of the GERIE study is to improve the health of elderly who permanently reside in nursing homes or of those who are exposed to indoor air pollution because of reduced mobility.
