Abstract

Time-activity diaries kept by members of the general public indicate that on average people spend around 90% of their time indoors. This is associated with considerable exposure to air pollutants as not only is there infiltration of pollutants from outdoors, there are also emissions indoors that can lead to elevated pollutant concentrations. Despite this, and the fact that the WHO produces air quality guidelines for indoor air, the only statutory requirements for monitoring of airborne pollutant concentrations relate to the outdoor environment. Given its importance as a source of air pollution exposure, increasing attention is being given to pollution of the indoor environment. This volume considers both chemical and biological pollutants in the indoor atmosphere from their sources to chemical and physical transformations, human exposure and potential effects on human health. It is a valuable reference for those working in environmental policy, civil and environmental engineering as well as for atmospheric chemists.

Abstract

The aim of the questionnaire study was to investigate what kind of changes a large renovation of the primaryschool Huutoniemen ala-aste had for the subjective experience of the environment as well as complaints and symptoms of the pupils. The reference school was the primary school Palosaaren ala-aste in which a major renovation was made earlier. The opinions of the pupils and other information were collected with a standardized and verified questionnaire produced byClinic of Occupational Medicine in the City ofÖrebro, Sweden. The questionnaire was sent to over 470 pupils in both schools before and after the renovation at the same time of the year in 1997 and 2000. Technical measurements of CO2, relative humidity and temperature in the indoor air were made before and after the renovation and at the same time of the year in 6-8 classrooms/school. The answers of the pupils in Huutoniemen ala-aste from the time before the renovation 1997 were compared to the answers after the renovation in 2000. In a similar way answers of the pupils in Huutoniemen ala-aste were compared to the answers from the reference school in 1997. The results were tested by the SPSS with Chi Square test for independence (p<0,05 or p<0,01). The subjective evaluation of the pupils of the environment as air quality, rooms, temperature, cleaning, lighting and noise were significantly worse in the object school than inthe reference school but became significantly better after the renovation. The prevalence of hay fever and long periods of cough duringthe previous yearwere significantly higher in the object school than in the reference school but were reduced significantly in the object school after the renovation. The prevalence of the present symptoms with headache and eye irritation was higher in the object school than in the reference school but was reduced in the object school significantlyafter the renovation. The subjective view whether the school was the cause of the present symptoms as tiredness, head-ache, eye irritation, symptoms of the nose, cough and the skin of the face and itch/tickle on the hair scalp/ears and symptomsof the skin of the hands were higher in the object school than in the reference school but were reduced significantly after the renovation. The medium level of the CO2 decreased dramatically in the object school during the lectures froma level of about 2220 ppm to about 870 ppmafter the renovation and was approximately at the same level as in the reference school. The renovation of the primary school Huutoniemen ala-aste gave a much better environment in the school for the pupils and teachers. Syftet med enkätstudien var att undersöka hur en omfattande renovering av en lågstadieskola Huutoniemen ala-aste ändrade elevernas subjektiva upplevelse av skolmiljön samt elevernas besvär och symptom. Som jämförelse undersöktes även en referensskola Palosaaren ala-aste som redan tidigare hade genomgått en omfattande renovering. Synpunkter och annan information insamlades med en standardiserad och prövad enkät utarbetad av Yrkesmedicinska kliniken i Örebro, Sverige. Enkäten delades ut till samtliga ca 470 elever i skolorna före och efter renoveringen och vid samma tidpunkt av åren 1997 och 2000. Tekniska mätningar av inomhusluftens CO2, relativa fuktighet och temperatur gjordes före och efter renoveringen och på samma tid av året i 6-8 klassrum/skola. Elevernas svar (Huutoniemen ala-aste) från tiden före renoveringen 1997 jämfördes med motsvarande svar efter renoveringen 2000. På samma sätt jämfördes elevernas svar i Huutoniemen ala-aste och elevernas svar från referensskolan år 1997. Resultatet testades med SPSS med Chi Square test av beroende (p<0,05 eller p<0,01). Elevernas subjektiva bedömning av skolmiljön i formav luftkvalitet, utrymmen, temperatur städning, belysning och bullerförhållanden var sämre i objektskolan än i referensskolan men blev signifikant bättre efter renoveringen. Prevalensen av elevernas hösnuva och långdragna hostperioder var högre i objektskolan än i referensskolan men minskade signifikant efter renoveringen. Prevalensen av elevernas nuvarande symtom av huvudvärk samt besvär av ögonen var högre i objektskolan än i referensskolan men minskade signifikant i objektskolan efter renoveringen.Elevernas subjektiva bedömning av skolan somorsak till nuvarande symtom: trötthet, huvudvärk, besvär av ögonen eller näsa, hosta, besvär av hud i ansiktet, fjällning/klåda i hårbotten/öron samt torr/kliande rodnad hud på händerna var högre i objektskolan än i referensskolan men minskade signifikant efter renoveringen. Medelvärdet av CO2 minskade i den renoverade skolan drastiskt under lektioner från en nivå 2220ppm till 870 ppm och var efter renoveringen på en ungefär samma nivå som i referensskolan. Renoveringen av Huutoniemen ala-aste har givit mycket bättre skolmiljö för elever och lärare.

Abstract

"In this paper the authors investigate individuals' exposure to indoor air pollution. Using new survey data from Bangladesh, they analyze exposure at two levels--differences within households attributable to family roles, and differences across households attributable to income and education. Within households, they relate individuals' exposure to pollution in different locations during their daily round of activity. The authors find high levels of exposure for children and adolescents of both sexes, with particularly serious exposure for children under 5. Among prime-age adults, they find that men have half the exposure of women (whose exposure is similar to that of children and adolescents). They also find that elderly men have significantly lower exposure than elderly women. Across households, they draw on results from their previous paper (Dasgupta and others, 2004), which relate pollution variation across households to choices of cooking fuel, cooking locations, construction materials, and ventilation practices. They find that these choices are significantly affected by family income and adult education levels (particularly for women). Overall, the authors find that the poorest, least-educated households have twice the pollution levels of relatively high-income households with highly-educated adults. For children in a typical household, pollution exposure can be halved by adopting two simple measures--increasing their outdoor time from 3 to 5 or 6 hours a day, and concentrating outdoor time during peak cooking periods. The authors recognize that weather and other factors may intervene occasionally, and that child supervision outdoors may be difficult for some households. However, the potential benefits are so great that neighbors might well agree to pool outdoor supervision once they became aware of the implications for their children's health. This paper--a product of the Infrastructure and Environment Team, Development Research Group--is part of a larger effort in the group to study environmental health issues in developing countries"--World Bank web site.
