An integrated environmental health impact assessment of road transport in New Zealand was carried out, using a rapid assessment. The disease and injury burden was assessed from traffic-related accidents, air pollution, noise and physical (in)activity, and impacts attributed back to modal source. In total, road transport was found to be responsible for 650 deaths in 2012 (2.1% of annual mortalit...

In 1992, 1998, and 2006, questionnaires were sent to stratified samples of residents aged 18-75 years living near petrochemical industries (n = 600-800 people on each occasion) and in a control area (n = 200-1,000). The aims were to estimate the long-term prevalence and change over time of annoyance caused by industrial odour, industrial noise, and worries about possible health effects, and to ...

  Background : Noise pollution and workers' noise exposure are common in industrial factories in Iran. In order to reduce this noise pollution, evaluation and investigation of noise emission are both necessary. In this study, different noise mapping methodsare used for determining the distribution of noise.   Materials and Methods : In the present study, for preparing a noise map i...

Background and Aim: Noise pollution is recognized as a major problem in urban areas. Therefore, the current study was aimed to determine noise pollution indices in Birjand old districts. Materials and Methods: In this cross-sectional and analytical-descriptive study, noise measurement was performed by means of "CEL" sound level meter (model 450.490). Equivalent noise level "Leq 10 min" was meas...

Indoor air pollution, specifically restricted in its meaning to chemicals in home indoor air environment, presents a new and probably an important challenge to the researchers of the air pollution field. The general overview of this topic suggests that the voluminous data generated in the past ten or so years have only defined the rudiments of the problem, and significant areas of research stil...

This study focuses on identifying source and frequency of noise pollution in Yazd, Iran. For data collection, we used two approaches: First we selected 55 monitoring stations for 122 km grid network; the distance between two stations was 2 km. Then, at the same time, we measured the sound pressure level (SPL) at main roads; the distance between two monitoring stations in this case was 1 km. Aft...
