Measures of a number of ventilation parameters and of a number of pollutants from 21 locations furnished data for evaluating interrelations among commonly used descriptors of ventilation as well as their relation to frequently measured indoor gaseous and particulate pollutants.
This investigation looks at sensory (odour, irritation) and physical criteria for ventilation requirements, paying particular attention to the difference between smoking and nonsmoking occupancy in a well-controlled environmental chamber.
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.
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

This paper discusses the measurement of air infiltration rates and reports on measurements relating indoor and outdoor aerosol size distributions in the 0.01 to 1 micron size range.
A study to assess personal exposure to respirable particles was conducted during January to March 1982 in Waterbury, Vermont. 48 non-smoking volunteers carried Harvard/EPRI personal samplers every other day for two weeks.
An indoor/outdoor monitoring study was conducted during January to March 1982 in Waterbury, Vermont. Respirable particle measurements were made inside and outside 24 homes (all occupants were nonsmokers), 19 with wood-burning appliances and 5 without. Data were also obtained on seasonal air exchange rate, heating fuel consumption, and relevant home characteristics. Findings indicate that indoor particle levels are consistently higher than outdoor values regardless of heating fuel type.
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.
Chemical pollutants and ventilation rate have been measured in newly built energy efficient private dwellings. The samples were taken in the absence of normal human activity in the houses. The data show that the main source of organic pollutants seems to be indoor building materials and furniture. For dust an important source could be the outdoor environment. Formaldehyde was primarily found in houses where chipboard was used while levels of radon daughters was very low in all houses tested.
