cement dust exposure is associated with increased respiratory impairment. as the major occupational hazard in the cement production industry is cement particles, our aim was to more thoroughly examine the acute effects of occupational exposure to cement dust on the respiratory system. a cross-shift study was conducted in a cement factory in iran. 100 high exposed workers from production and pac...
Background : Occupational exposure to dust generated in the process of carpet weaving which can lead to pulmonary complications. The aim of this study was to investigate the association between exposure to carpet dust size and parameters of lung function. Method : This retrospective case-control study was performed on 95 carpet weaver City Khomein. The total exposure inhaled ca...
Sorghum stemborer species remains key yield limiting factor for sorghum production in the Nigerian semi-arid region. When they can afford, farmers rely almost solely on synthetic insecticides for control. Owing to the misuse and environmental and health challenges attributed to the use of synthetic insecticides, a two-year field study was carried out at the University of Maiduguri Research Farm...

Dust deposition phenomenon is an important climatic and environmental issue in arid and semi-arid regions. The objective of this study was to examine important characteristics of atmospheric dust in Kerman as one of the major cities in arid areas of our country with high potential of dust production. Dust samples were collected monthly using glass traps installed on the roof of 35 one-story bui...
ABSTRACT: Overall plant growth and microbial biomass can be effected by dust accumulation. The chloroform fumigation-extraction method was used to evaluating the effect of cement dust pollution emitted from Kurdistan cement factory on soil microbial biomass carbon. Chlorophyll content (a, b and total) of plants species was measured in different distance from cement factory. Mic...
Background and aims: Mining is categorized with considerable exposure to airborne contaminations. Regarding the high prevalence of diseases and the high population of workers in iron ore mines, the aim of this study was to investigate the effect of miners’ exposure to respirable dust compounds on the serum Malondialdehyde (MDA) levels. Methods: In this study, 92 non-smoker healthy workers of G...
Wind erosion is the most important geomorphic process and the main cause of the landscape change in arid and semi-arid areas. This paper focuses on the Dust Storm Index (DSI) with the aim of monitoring wind erosion in Central Iran using meteorology data. The trend of standardized DSI and its three factors which are sever dust storm, moderate dust storm and local dust events were studied using M...
