Environews #1 is, hopefuly, the first of a series dealing with current issues of environmental concern. This issue discusses the possible role of climate change in the massive floods that followed hurricane sandy, depletion of the world's fish stocks, the possible role, bothe positive and negative, of aquaculture, and the trend to seek oil in increasingly environmentally dangerous venues.

This article describes an experiment that was carried out on an existing building to test the validity of the system ventilation efficiency equation for multiple-zone recirculating systems of ANSI/ASHRAE Standard 62.1. The system ventilation efficiency equation (SVEE) can be applied to buildings that use a recirculating air distribution system. It accounts for the fact that the return air carries some “unused” outdoor air, so that the amount of new outdoor air introduced at the air handler can be reduced. The SVEE is based on a mass balance but infiltration and interzonal mixing are not included in the formulation. Since infiltration …

Pure food and water have been legislated in the United Sates since 1906 with the passing of the Pure Food and Drug Act. In spite of regulations and enforcement, unintentional additives are still a part of our food and water supply. This paper addresses the issue of pharmaceutical residues and chemicals which act as endocrine disruptors found in the food and water supply in the US.
