“…IMA-Europe represents the European producers of andalusite, bentonite, borates, calcium carbonate, cristobalite, diatomite, dolomite, feldspar, kaolin, kaolinitic clays, lime, mica, quartz, sepiolite, talc, vermiculite and wollastonite. A prospective IMA-Europe Dust Monitoring Programme (IMA-DMP) was initiated to build a body of statistically reliable data that could be used in discussions with authorities about future OEL setting and which would be suitable for future epidemiological studies 10. This, still ongoing, initiative also allowed participating companies to check compliance with OELs set by regulatory authorities at the European level and in the respective countries, to identify hotspots with high exposures and to implement further control measures where needed.…”

“…More recently, from 2010 onward, also sites from Eastern Europe, Russia, Turkey and Ukraine enrolled into the programme. At present, the IMA-DMP database contains the largest number of occupational personal exposure measurements of respirable dust and RCS (quartz) collected systematically within a single industrial sector 10. The body of literature regarding (recent) long-term temporal trends in occupational exposures to RCS is small.…”

ObjectivesSince 2000 the European Industrial Minerals Association’s Dust Monitoring Programme (IMA-DMP) has systematically collected respirable dust and respirable quartz measurements from 35 companies producing industrial minerals. The IMA-DMP initiative allowed for estimating overall temporal trends in exposure concentrations for the years 2002–2016 and for presenting these trends by type of mineral produced, by jobs performed and by time of enrolment into the DMP.MethodsApproximately 32 000 personal exposure measurements were collected during 29 sampling campaigns during a 15-year period (2002–2016). Temporal trends in respirable dust and respirable quartz concentrations were studied by using linear mixed effects models.ResultsConcentrations varied widely (up to three to four orders of magnitude). However, overall decreases in exposure levels were shown for the European minerals industry over the 15-year period. Statistically significant overall downward temporal trends of −9.0% and −3.9% per year were observed for respirable dust and respirable quartz, respectively. When analyses were stratified by time period, no downward trends (and even slight increasing concentrations) were observed between 2008 and 2012, most likely attributable to the recent global economic crisis. After this time period, downward trends became visible again.ConclusionsConsistent and statistically significant downward trends were found for both exposure to respirable dust and respirable quartz. These downward trends became less or even reversed during the years of the global economic crisis. To our knowledge, this is the first time that analyses of long-term temporal trends point at an effect of a global economic crisis on personal exposure concentrations of workers from sites across Europe.

Blood Oxidative Stress Levels in Workers Exposed to Respirable Crystalline Silica in the West of Iran

Background: Occupational exposure to crystalline silica is still an important health problem, especially in developing countries. Exposure to silica may be associated with the induction of toxic oxidative stress. Objectives: This study was conducted to assess oxidative stress biomarkers in workers exposed to respirable crystalline silica (RCS) in Hamadan city, the west of Iran. Methods: This descriptive-analytical study was conducted on two groups of exposed workers selected from four industries and unexposed office workers in 2017. The analysis of RCS in air samples was done by NIOSH method No. 7602. Malondialdehyde (MDA), total antioxidant capacity (TAC), and catalase (CAT) activity were measured in serum samples. Results: In this study, 48 healthy workers exposed to silica and 47 unexposed workers as controls were selected. The mean MDA levels (26.91 ± 14.26 nmol/mL) and CAT activity (10.83 ± 5.06 U/mL) were higher in the exposed group than in the unexposed group (P < 0.001). However, no statistically significant difference was observed in the TAC levels between the groups and no correlation was observed between exposure to RCS and oxidative stress biomarker levels in exposed subjects. Conclusions: Although there was a significant difference in the oxidative stress levels between the groups, according to other results of our study, it is not possible to claim that oxidative stress biomarkers are appropriate biological indices for silica exposure monitoring in occupational settings. Therefore, we still require a comprehensive study of other aspects of this research field.

“…As lungs offer a large surface of contact, occupational and environmental chemical hazards are better absorbed into the circulation and can lead to acute or chronic poisonings, precipitating acute cardio-vascular events, inducing cancers, especially lung cancer in non-smokers [10], or autoimmune diseases [11,12]. Therefore, beside recent exposure effects, which are far from being standardized in Europe [13], respiratory diseases and disorders continue to be the leading cause of disability related to occupation, and the evaluation of the medium and long term effect of respiratory poisonings on lung function decline are gaining, also, importance [14]. Spirometry is the most currently used test in occupational medicine for all respiratory exposure hazards [15].…”

Regarding the widely distribution of respiratory exposure hazards in occupational settings, workers have an increased risk for chronic lung diseases. For assessing the quality of life and lung function in workers exposed to chemicals and dust, St George�s Respiratory Questionnaire (SGRQ) and spirometry were performed among 40 patients, admitted in Occupational Clinic Department of Colentina Hospital, Bucharest, Romania, during February, 2017. SGRQ showed different predictors for patients according to their occupational exposure and total symptoms score correlated better with decreased spirometric parameters in defining lung function deterioration. Quality of life is earlier affected than lung function deterioration and emphasises the need of more sensitive methods for an earlier identification and better evaluation of respiratory hazards in different workplaces.
