background: air pollution is one of the most important factors threatening the health of citizens. it increases the prevalence of cardiovascular and respiratory diseases as well as emergency admissions to hospitals in the polluted metropolitan cities. the present study was conducted using air quality (airq) model and aimed to investigate the effects of air pollution on the number of emergency c...

Spirometric data from 86 primary school children living in an area of air pollution resulting from wire reclamation incineration were analysed and compared with 92 non-exposed schoolchildren. There were lower values for forced vital capacity and forced expiratory volume and thus a higher incidence of pulmonary function abnormalities in the children in the polluted area than those in a non-pollu...

Objective: There are many communities at risk by a series of air pollution episodes. Tehran is one of the most polluted cities in the world. The presence of one or more air pollutants with a certain concentration in a particular period of time can cause several adverse effects on human and animals’ well-being that can cause much morbidity. There are several pollutants in the ai...

A modeling study using hourly meteorological and pollution concentration data from across the coterminous United States demonstrates that urban trees remove large amounts of air pollution that consequently improve urban air quality. Pollution removal (O3, PM10, NO2, SO2, CO) varied among cities with total annual air pollution removal by US urban trees estimated at 711,000 metric tons ($3.8 bill...

Environmental pollution consists of different types of pollutants in air, soil, and water. Due to the fact that plants can respond to environmental pollution, they can be used as bio-indicators for environmental monitoring. Air pollution in areas with oil and gas refineries nearby is an important problem. This study aims to survey the effects of gas refinery air pollutants on Conocarpus erectus...

BACKGROUND This study aimed to compare the cytochrome P450 1A1 (CYP1A1) gene expression in the cord blood of infants born from mothers living in low- and high-air polluted areas. MATERIALS AND METHODS The study was conducted in Spring 2012 in Isfahan, the second large and air-polluted city in Iran. The study comprised 60 neonates, consisting of 30 infants born from mothers residing in areas w...

Air pollution, especially haze pollution, is creating health issues for both humans and other animals. However, remarkably little is known about how animals behaviourally respond to air pollution. We used multiple linear regression to analyse 415 pigeon races in the North China Plain, an area with considerable air pollution, and found that while the proportion of pigeons successfully homed was ...

Wireless sensor networks have been deployed for environmental monitoring over the last twenty years. However, this application is not frequently deployed to solve the environmental problems (e.g. air pollution detection) encountered by many African countries. This paper develops an architecture based on a Wireless Mesh Network of Sensors (WMNS) to measure air pollution in African cities. We are...
