“…Exposures in this operation were reduced from 20mg of respirable dust per cubic centimeter of mortar removed to less than 0.2mg/cc of mortar removed with the use of a ventilated grinder [Heitbrink et al, 2001]. Respirable dust levels were reduced by at least 90% using Local Exhaust Ventilation (LEV) on cut-off saws in the construction industry [Thorpe et al, 1999]. In the mineral processing industry, the cleaning chamber reduces the amount of dust that escapes from the bags as they move from the loading station to the stacking station.…”

Background The failure to recognize occupational health as an economic phenomenon limits the effectiveness of interventions ostensibly designed to prevent disease and injury. Hence, consideration of economic efficiency is essential in the evaluations of interventions to reduce hazardous working conditions. In this paper, we present an analysis of the cost effectiveness of alternative means of preventing silicosis. Methods To evaluate the cost effectiveness of specific interventions for the prevention of occupationally induced silicosis, we have used the simulation models based on the generalized cost‐effectiveness analysis (GCEA) developed by the WHO‐CHOICE initiative for two representative subregions namely AMROA (Canada, United States of America), and WPROB1 (China, Korea, Mongolia). Results In both of the two subregions, engineering controls are the most cost effective with ratios varying from $105.89 per healthy year or disability adjusted life year saved in AMROA to approximately $109 in WPROB1. In the two subregions, the incremental cost‐effectiveness ratio of engineering controls (EC) looks most attractive. Although dust masks (DM) look attractive in terms of cost, the total efficacy is extremely limited. Conclusions To the extent that this analysis can be generalized across other subregions, it suggests that engineering control programs would be cost effective in both developed and developing countries for reducing silica exposure to save lives. Note that this analysis understates health benefits since only silicosis and not all silica‐related diseases are considered. Am. J. Ind. Med. 48:503–514, 2005. © 2005 Wiley‐Liss, Inc.

“…Thus, it is established that the cause of environmental risks for residents of 2 apartments are poorly executed work on thermal insulation and infringement of the technology of pouring using the thermal insulation material of the composite "Poroplast CF 02" for the insulation of the expansion joint between the block sections. Most likely, when performing the thermal insulation works, the requirements of the technological procedure for manufacturing or the use of poor-quality raw materials were violated, an incorrect dosage of reagents was made and the thermal insulation became a source of toxic substances release into the air of the apartments surveyed due to infiltration processesair permeability of brickwork and became a source of environmental risk for residents of these apartments [8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Abstract. The residents of modern megacities are exposed to environmental risks arising both directly in the urban environment and their own dwellings. Modern polymeric building materials are the sources of toxic substances release into the air that have a significant impact on the population health. The objective of the work is the ecological and hygienic study of the air in the apartments of Irkutsk after repair work on the roof and walls insulation using the technology of pouring and calculation of the potential environmental risk for the residents. The object of the research was the indoor air in one of the houses in Irkutsk tested for formaldehyde and other toxic substances. After putting the house into operation, some defects were foundthe freezing of the walls of the building attic part. During the repair work, the mansard part of the building was heat-insulated by the pouring method using the composite material "Poroplast CF 02". High concentrations of formaldehyde and styrene were detected in the apartments exceeding the MPC in 4-8 times. The hazard ratio for inhalation exposure to harmful substances exceeds the safety level by 10 times. Consequently, there is a high probability of obtaining acute and chronic poisoning and developing cancer.

“…Many construction tasks have been associated with overexposure to dust containing crystalline silica [Chisholm 1999, Flanagan et al 2003, Rappaport et al 2003, Woskie et al 2002. Among these tasks are tuckpointing, concrete cutting, concrete grinding, abrasive blasting, and road milling [Nash and Williams 2000, Thorpe et al 1999, Akbar-Kanzadeh and Brillhart 2002, Glindmeyer and Hammad 1988, Linch 2002, Rappaport et al 2003]. …”
