Without any question, environmental pollution is the main cause for the species extinction in recent times. In this paper, based on impulsive differential equation, the dynamics of a single-species model with impulsive pollution treatment at fixed time in a polluted environment is considered, in which we assume that the species is directly affected by the pollutants. Sufficient conditions for p...

Mercury pollution is a persistent and increasing problem in the environment. Along with some natural sources of the metal, major man-made sources of mercury pollution include incinerators, fossil fuel plants, and municipal sewage systems. The EPA estimated that in 1989, approximately 643,000 kg of mercury was discarded as municipal solid waste, with 84% of it landfilled.

The present study provides an evaluation of road traffic noise pollution in the city of Amman and its effects on residents. Statistical noise index L10(18 hr) was measured at nine different sites throughout the city of Amman. The British Calculation of Road Traffic Noise (CRTN) method was used to predict noise levels at the chosen sites. The CRTN method proved to be successful in predicting noi...

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 ...

Monitoring and managing urban air pollution is a significant challenge for the sustainability of our environment. We quickly survey the air pollution modeling problem, introduce a new dataset of mobile air quality measurements in Zurich, and discuss the challenges of making sense of these data.

This brief paper provides background reading for the Population-Environment Research Network’s online seminar on ‘Air Pollution and Health Linkages,’ scheduled for December 1-15, 2003. The purpose of this ‘cyberseminar’ is to foster a discussion that will lead to identification of key issues, knowledge gaps, and methodological shortcomings in understanding health impacts of air pollution, both ...
