Indoor air quality (IAQ) control of hospitals plays a critical role in protecting both hospital staffs and patients, particularly those who are highly susceptible to the adverse effects of indoor noxious hazards. However, moxibustion in outpatient departments (OPDs) of traditional Chinese medicine (TCM) may be a source of indoor air pollution in hospitals. Some studies have investigated indoor ...
background: today, air pollution is one of the major problems in large cities including isfahan. methods: the objective of this study was to investigate the variations of ozone (o3), carbon monoxide (co), nitric oxide (no), nitrogen dioxide (no2), nitrogen oxides (nox), sulphur dioxide (so2), and particulate matter (pm10) concentrations in different months at three stations and also to explore ...
Introduction: Nowadays, the cement industry is regarded as one of the most important air pollution industries globally. This study aimed to simulate the emission of NOx, CO, SO2, and PM pollutants caused by the Sabzevar Cement Factory chimney by SCREEN3 software. Materials and Methods: In this study, the SCREEN3 software was employed for the distribution of NOx, CO, SO2, and PM pollutants. Th...
Air pollution, as an environmental factor affects the health status and growth of the fetus, considering that the air pollutants have dramatically increased in Tehran, reviewing the effects of them on the health situation of infants, which are very vulnerable seems to be of great importance. Hence, a retrospective cohort study was conducted on 1000 randomly selected newborns with gestational ag...
nowadays, air pollution in cities with regard to its harmful outcomes has been turned into one of the serious challenges in urban management. pollutants as carbon monoxide, sulfur dioxide, and the aerosols that are known to be among the most important factors related to heart, vascular, and lung disease, have underlined public welfare and health, and the organizations concerned with community h...
Background and objectives: Tehran is one of the most polluted cities in the world in terms of air pollution. Modeling is a useful tool in air pollution management. The objectives of this study are to determine the distribution of the main air pollutants concentration in Tehran and to construct a photochemical model appropriate to the geography and natural characteristics of Tehran. Methods: I...
Background & purpose: Air pollution has been known as one of the most effective factors on cardiovascular, pulmonary and infectious diseases. This study aims to determine the relation between mortality rate and air pollution in Mashhad during 2007-2009. Materials & Methods: Data of air pollution, mortality rate and geographic factors were collected during 2007-2009 and analyzed. Mortality rate,...
background: in addition to gas pollutants, many chemicals and air pollutants are in the form of particulate matter. particulate matter consists of a complex mixture of variable sized particles and physicochemical composition. these particles mainly contain minerals including fe, al, ca, k, cu, ti, mn, ni, v and their size, chemical composition and concentration are important to assess the exten...
Abstract Background: Due to the relationship between air pollution and occurrence of de-novo heart failure (HF) or decompensation of symptoms of HF, we aimed to evaluate such relationship in HF admissions in Isfahan hospitals. Materials and methods: This case-crossover study is performed on 120 patients with mean age of 65.9±10.4 (45-86 years old) from cases referred to hospitals, which resulte...
Background & Objectives: Air pollution in is one of the main difficulties in Megacities that have harmful effects on humans and the environment and cause various diseases including cardiovascular disease. So, present study with aim of Study the number of cases cardiovascular mortality Attributed to CO in Tehran in during a five-years were performed. Metho...
