A total of 20 toxic, carcinogenic, or mutagenic organic compounds were measured in the air and drinking water of 355 residents of Bayonne and Elizabeth. New Jersey, in the fall of 1981. The participants were selected from over 10,000 residents screened by a probability sampling technique to represent 128,000 persons (over the age of seven) who live in the two neighboring cities. Over one hμndred geographic areas throughout the two Cities were selected for monitoring. Each participant carried a personal sampler with him during his normal daily activities for two consecutive 12-h periods.

Simultaneous air monitoring inside and outside of 12 homes in the Houston area were performed for fine inhalable particulate matter by means of dichotomous samplers. The patterns of house-specific indoor mean concentrations, indoor/outdoor ratios, and probable source of indoor fine aerosol are discussed, along with pertinent information on household characteristics.

Air pollution has been associated with an increased incidence of respiratory disease. However, significant differences may exist between air pollution levels measured at conventional fixed monitoring stations and actual levels inhaled by a subject. Furthermore, studies of effects of air pollution might best be done using asthmatics as study subjects, since they have irritable airways. This is a preliminary report of a study using a control and asthmatic group in which effects of air pollution are assessed by symptom and medication diaries and simple pulmonary function tests.

Vehicle emissions depend directly on urban driving patterns which are an integral part of a wider range of urban features including density of settlement, car ownership, status of public transport, etc. Thus the conditions vehicles experience and their consequent emissions are directly related to the urban fabric. A methodology of sampling an urban area is developed by defining homogeneous areas within the city in terms of their activity intensity, modal split and social/economic status.

The constructive uses of vegetation in building engineering services are acoustic quieting, air molecular and particulate filtration, water filtration and chemical polishing, shading from solar gain, cooling and humidification. A water conservation regime should form part of the integrated solution.

The present study was designed to assess health effects in residents of a Bulgarian city polluted by a transboundary chlorine emitter. The study was undertaken on account of the local population's complaints of pervasive specific odour and irritation of respiratory ways and the eyes. The study aimed at assessment of both acute and long-term effects of exposure to air pollution.
