background: cement production is associated with heavy metal emissions and environmental pollution by cement dust. the degree of contamination of drinking water sources by major and trace elements present in cement dust generated by united cement factory (unicem) is still uncertain. this study estimated the element content of ground and surface water samples (hand-dug wells, boreholes and strea...

Background: Cement production is associated with heavy metal emissions and environmental pollution by cement dust. The degree of contamination of drinking water sources by major and trace elements present in cement dust generated by united cement factory (UNICEM) is still uncertain. This study estimated the element content of ground and surface water samples (hand-dug wells, boreholes and strea...

heavy metals, e.g. cd and pb emit and release into the environment during cement production and are deposited into soils. this research was carried out to determine the concentration and spatial distribution of trace elements in top soils around the kurdistan cement factory, west of iran in order to evaluate the effect of cement factory on the environment. twenty-four soil samples were collecte...

Background: Reducing the effects of climate change and air pollution is a global priority at present. To formulate effective policies for achieving such a reduction requires a good understanding of the underlying phenomena. This study assessed the role of Nasr Kashan Factory in the emissions of particulate matter (PM). Methods: In this cross-sectional study, PM concentrations at 9 stations ins...

It is very important to analyze the various kinds of light environment of a plant factory to provide the optimal growth conditions to the cultivated plants. In this paper, we propose an intelligent simulation tool which can be utilized in a construction of a real plant factory using virtual environment techniques. Incoming light to the virtual environment can be divided into natural and artific...

the deficiency of wooden resources and rising demand of wood and paper products caused an increasing interest to the lignocellulose resources in the production of paper and wood composite production, such as bagasse. in khuzestan province for build units of wood and paper industries with the approach of using bagasse as a raw material, 6 main indicator and 35 sub-indicator were prioritization. ...

The association of malignant mesothelioma (MM) and nonoccupational asbestos exposure is currently debated. Our study investigates environmental and domestic asbestos exposure in the city where the largest Italian asbestos cement (AC) factory was located. This population-based case-control study included pleural MM (histologically diagnosed) incidents in the area in 1987-1993, matched by age and...

Background: The release of metals from industrial factories is one of the most important sources of environmental pollution. The present study aimed to determine the concentration of heavy metals like cadmium (Cd), chromium (Cr), manganese (Mn), nickel (Ni), and lead (Pb) in dust around the cement factory. Methods: A total of 22 dust samples were collected from areas around the cement factory...

BACKGROUND In 2013, an unusually high incidence of biliary tract cancer among current or former workers of the offset color proof printing department of a printing company in Osaka, Japan, was reported. The purpose of this study was to examine whether distance from the printing factory was associated with incidence of biliary tract cancer and whether incident biliary tract cancer cases clustere...
