Background and purpose: Particulate matter less than 10 microns (PM10) is one of the main pollutants that cause irreparable damage to the environment and human health. The aim of this study was to estimate the health effects of PM10 on human health. Materials and methods: This analytic study was conducted in Bushehr, 2013. PM10 data were obtained from Bushehr Meteorological organization an...
INTRODUCTION There is still interest in a unified methodology to quantify the mass of particulate material emitted into the atmosphere by activities inherent to open-pit mining. For the case of total suspended particles (TSP), the current practice is to estimate such emissions by developing inventories based on the emission factors recommended by the USEPA for this purpose. However, there are d...
The current air quality limit values for airborne pollutants in the UK are low by historical standards and are at levels that are believed not to harm health. We assess whether this view is correct. We examine the relationship between common sources of airborne pollution and population mortality for England. We use data at local authority level for 1998-2005 to examine whether current levels of...
BACKGROUND Ambient air pollution is suspected to cause lung cancer. We aimed to assess the association between long-term exposure to ambient air pollution and lung cancer incidence in European populations. METHODS This prospective analysis of data obtained by the European Study of Cohorts for Air Pollution Effects used data from 17 cohort studies based in nine European countries. Baseline add...
Epidemiologic evidence associates particulate air pollution with cardiopulmonary morbidity and mortality. The biological mechanisms underlying these associations and the relationship between ambient levels and retained particles in the lung remain uncertain. We examined the parenchymal particle content of 11 autopsy lungs from never-smoking female residents of Mexico City, a region with high am...
The development of gasoline direct injection (GDI) engines has provided a strong alternative to port fuel injection engines as they offer increased power output and better fuel economy and carbon dioxide emissions. However, particulate matter (PM) emission reduction from GDI still remains a challenge that needs to be addressed in order to fulfil the increasingly stricter environmental regulatio...
OBJECTIVES The objective of this study was to conduct a systematic review to provide summarized evidence on the association between maternal exposure to particulate air pollution and birth weight (BW) and preterm birth (PTB) after taking into consideration the potential confounding effect of maternal smoking. METHODS We systematically searched all published cohort and case-control studies exa...
background: the objective of this study was to measure the total suspended particulate (tsp), pm 10 and pm 2.5 air particulates in the selected intercity bus stations located in the central square of hamadan, to review the distribution concentration of the air particulates content and to evaluate its possible health risk to the people who spent little time of their daily time in those places. m...
Air pollution by particulate matter (PM) in cities is an ongoing problem with increasing severity. The biggest PM contributors are traffic and domestic fire burning. With the shift towards electromobility use of low-emission fuels, attention should be shifted to less mentioned sources pollution. Such include wind-induced resuspension. This study focuses on determining threshold wind speed causi...
24-hour samples of pm1 (submicron particles, aerodynamic diameters ≤1 μm) and pm2.5(fine particles, aerodynamic diameters ≤ 2.5 μm) were collected at a quasi-rural area in racibórz (1 january-30 june 2011). the samples were analysed for carbon (organic and elemental), water-soluble ions (na+,nh4 +, k+, mg2+, ca2+, cl-, no3 -, so4 2-) and concentrations of 21 elements with a carbon analyser (sun...
