To find out the influence of a short period of ventilation on the indoor formaldehyde concentration inside a new building, an investigation was conducted for the instance of twice ventilation in a day through window opening. The results showed that the initial concentration of formaldehyde was 3.53 -8. 48 times as high as the concentration after 10 min ventilation. After closing the window, the indoor formaldehyde concentration increased with time and followed an exponential equation of C = C0 exp（ - b ＊ t） ＋ （ a ＋ Cu, ） [ 1 - exp（ - b ＊ t） ] with correlation coefficient （ R^2 ） of 0. 945 - 0. 999, based on the statistical analysis of 14 groups of measurement data. The developed equation can be used to estimate the emission rate of indoor formaldehyde sources and the air exchange rate of the test room simultaneously.展开更多

Several studies showed that health care meant to improve people＇s health is an important source of disease. Good clinical practices aim to maximize effectiveness and therapeutic compliance, minimize risks and costs, respecting the patient＇s choice from generic drugs, also from the moment of prescribing, the supervision of drug-related events must be taken into account, not only on the patient but also in the environment. Pharmacovigilance and pharmacoecovigilance have to be conceived as a clinical practice in dentistry. There is no established culture of drug induced reaction reports by dentists in Uruguay, and awareness of environmental care is incipient. The pharmacy of faculty of dentistry, （Universidad de la Repfiblica）, an institutional project that has been developed since 2006, is in a transformation process. The pharmacovigilance dentistry Node is in full development. The toxicovigilance and pharmacoecovigilance activities are recent. The general aim of this project was to establish the pbarmacovigilance, toxicovigilance and pharmacoecovigilance clinical practice in dentistry. The widespread use of cosmetic as toothpastes, or mouth rinses, drugs and dental materials, as well as exposure to chemical contaminants through the population＇s living habits and the environmental damage caused by drug wastes requires comprehensive and up-to-date information to establish rational strategies.展开更多
