Exposure monitoring and health surveillance of coal mine workers has been improved in Australia since workers’ pneumoconiosis was reidentified 2015 Queensland. Regional variations the prevalence dust lung disease have observed, prompting a more detailed look into size, shape, mineralogical classes that are being exposed to. This study collected respirable samples ambient air from three operatin...

Background: Hematological effects and digestive and neuro-psychological signs and symptoms are some manifestations of lead toxicity. However, there are conflicting reports of their prevalence among lead exposed workers and their relationship with blood lead levels (BLL). This case- control study assessed the relationship between BLL and hematological indexes and digestive (abdominal colic, ir...

background: occupational lead poisoning is a health problem in iran. it has not previously been studied in traditional tile makers. objective: to determine the prevalence of lead poisoning and its complications in traditional tile workers in mashhad, northwest of iran. methods: we visited workers in two traditional tile factories and collected data by direct history taking and physical examinat...

Environmental sustainability needs to use resources efficiently and effectively from macro to micro level with a systematic approach. The dualistic relationship between ecosystem and human beings require considering ecological and social systems as well as economic factors known as the three-legged approach. Individuals and their perceptions are also important in this approach because of the ne...

Five samples of soil collected from a lead and zinc mine were used to assess the effect of combined contamination of heavy metals on soil bacterial communities using a polyphasic approach including characterization of isolates by culture method, community level catabolic profiling in BIOLOG GN microplates, and genetic community fingerprinting by denaturing gradient gel electrophoresis of 16S rD...

Silicosis, a debilitating and potentially deadly lung disease, develops through inhalation of excessive concentrations of respirable crystalline silica dust. In underground coal mines, continuous miner operators have a high risk of overexposure to silica, with approximately 25% of compliance dust samples exceeding the permissible exposure limit. Continuous miners often extract high-silica-conte...

Introduction: Dust is one of the significant factors which cause occupational respiratory diseases among workers. Objective: The main purpose of this study was to determine the dust concentration, its silica percentage and comparison with standard. Method: This cross-sectional study was carried out at one of iron-stone ores in Southern Khorasan province. Air dust sampling was done using the NIO...
