Pollutant emission rates from indoor combustion appliances and sidestream cigarette smoke.

Particulate and gaseous emissions from indoor combustion appliances.and smoking can elevate the indoor concentrations of various pollutants. Indoor pollutant concentrations resulting from operating one or several combustion appliances, or from sidestream tobacco smoke, were measured in a 27m3 environmental chamber under varying vent ilation rates. The combustion appliances investigated were gas-fired cooking stoves, unvemed kerosene--fi red space heaters, and unvented natural gas-fired space heaters. 

Energy use, infiltration, and indoor air quality in tight, well-insulated residences.

Two bi-level houses in Gaithersburg, Maryland, USA, of identical design and construction were studied to determine the relationships among air exchange, energy consumption, and indoor pollutants. The experimental house was retrofitted and equip

Effect of unvented combustion appliances on air exchange among indoor spaces.

The effects of operating unvented appl i ances and opening windows on indoor pollutant levels and air exchange rates are being studied under the sponsorship of the Gas Research Institute. The study is being conducted i n an instrumented, well-characterized bilevel house located near Washington, D.C. Air leakage due to window openings is characterized by pressurization measurements and the air exchange increment is characterized through tracer gas measurements. Two unvented space heaters, one radiant and the other convective, are operated singly and in combination with a gas cooking range.

Indoor air quality environmental information handbook: combustion sources.

This environmental information handbook was prepared to assist both the non-technical reader and technical persons, such as researchers, policy analysts, and builders/designers, understand the current state of knowledge regarding combustion so

Indoor air quality in tight houses: a literature review.

Results of a forty house indoor air pollutant monitoring study.

A study was conducted in 40 homes in the areas of Oak Ridge and West Knoxville, in the summer and winter months, to quantify concentrations of COx, NOx, particulates, formaldehyde, and radon, as well as selected volatile organic compounds. 

Indoor air pollutants: exposure and health effects.

Reviews current knowledge about the sources of a number of indoor pollutants and their concentrations: tobacco smoke, NO2, CO, radon, formaldehyde, SO2, CO2, O3, asbestos, mineral fibres, organics and allergens. Lists the adverse health effects from exposure to each of the pollutants. Finds instrumentation for measuring exposure acceptable, but monitoring and knowledge of distribution of sources and concentrations inadequate or marginal. Knowledge of exposure-effects relationship is inadequate, especially with regard to delayed effects of chronic exposures.

Dynamic behaviour of pollutants generated by indoor combustion

When indoor air concentrations from indoor combustion processes are estimated, source strengths and ventilation rates are usually considered. Recent studies, conducted in the Energy Research House at Iowa State University, indicate that seve

Indoor air quality. 20 existing homes.

Complaints related to moisture problems in houses which had been air sealed, led to a study of indoor air quality in 20 weatherized demonstration homes in the Cambridge, Ontario area. 

Air-to-air heat exchangers for energy efficient ventilation of "tight" structures.

Reducing the air change rate of a house increases the concentration of pollutants in the indoor air. These pollutants are identified and located within the residential structure. Air-to-air heat exchangers are suggested tocontrol ventilation, and the three basic types described.
