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...

the objective of this study was to simulate carbon monoxide (co) dispersion exited from the stacks of a cement industry in doroud, iran by gaussian model (gm). four sampling period was conducted for the measurement of co from the factory's three-stack flow during a period of one year. the input parameters were the rate of co emission, meteorological data,  factors related to the stack, and...

introduction precipitation, an intrinsic part of nature, is essential not only for the survival of human but also for that of plants and animals. yet, this valuable natural phenomenon can also jeopardise human life, flora and fauna. torrential rains are sudden events that wreak havoc in iran and other parts of the world. in recent years, due to man's abuse of nature and disruption of environmen...

A historical prospective cohort study comprised all persons employed from 1950 to 1981 for at least three years in the oldest asbestos cement factory in the world. From 2816 persons eligible for the study, record based estimates and measurements of dust and fibres and histories of smoking based on interviews were used to calculate individual exposures over time. After observation of 51,218 pers...

The aim of the present work was to assess the emission of different persistent organic pollutants from a cement plant over a period of one year, under normal operational conditions. Thus, a long-term sampling device was installed in the clinker kiln stack of the cement plant. The factory uses petroleum coke as primary fuel, but also alternative fuels such as solid recovered fuel (SRF), automoti...

Objectives: This study aimed to assess exposure to crystalline silica and its relation with risk of pulmonary functional disorders among workers of a cement industry in Saveh, Iran.Methods: In this cross-sectional study, 62 samples of respirable dust were collected from breathing zone of workers in different sections of a 4-years-old cement factory in 2011. Determination ofrespirable dust conce...

Background: Soil pollution and accumulation of heavy metals in crops in industrial areas is one of the most important environmental issues threatening the life of plants, animals, and humans. The aim of this study was to determine the concentration of Cr and Cd in the soil and barberry plants in farms surrounding the Qayen Cement Company, South Khorasan Province, Iran. Materials and Methods:...
