Investigation of the occupational health and safety conditions in Hellenic solid waste management facilities and assessment of the in-situ hazard level

Due to tenuous working conditions and working accidents in the past, sufficient safety measures for the personnel in certain solid waste management facilities are deemed a necessity. Besides the fact that such facilities are equipped with heavy machinery associated with safety risks, the working environment poses additional health risks to the personnel, due to their exposure to various waste-derived emissions. Therefore, it is required to establish and preserve the safety and hygienic conditions but also to equip and train their personnel during all waste treatment and management stages. Presented in this work are the results of a field research which aimed to evaluate the health and safety conditions in operating Hellenic Solid Waste Management facilities. For the performed data mining, structured questionnaires were used and interviews with facility Safety Officers and workers were held. Facilities included sanitary landfills, recycling plants, transfer stations, mechanical-biological treatment plants and a HealthCare Waste incinerator. Major outcome was the overall evaluation of Occupational Health and Safety measures of the facilities (material Recovery and composting facilities are those with the higher hazard level), as well as the evaluation of high-risk parameters (“dust” and “litter, animals and insects in the perimeter” are found to constitute the major health hazards for the facilities' personnel). The limitation of the latter parameters and the adoption of measures towards it by decision makers or facility managers/stakeholders will lead in best-practice practical guidelines.

Occupational exposures to solvents and metals are associated with fixed airflow obstruction

Our study is the first to investigate the associations between exposures to solvents and metals using lifetime work history calendars and fixed airflow obstruction (AO). We have shown that increasing cumulative exposure-unit years to chlorinated solvents is associated with fixed AO. We found that women were at increased risk of fixed AO with increasing cumulative exposed-unit-years to chlorinated solvents but not men.

Evaluation of high blood pressure and obesity among US coal miners participating in the Enhanced Coal Workers' Health Surveillance Program

Since 2005, the Enhanced Coal Workers' Health Surveillance Program (ECWHSP) has offered respiratory examinations to coal miners in a mobile examination unit. As little is known about the cardiovascular health of coal miners, we describe the prevalence of high blood pressure (BP) and obesity among ECWHSP participants. During 2015, 1402 ECWHSP health examinations were performed. The prevalence of BP consistent with hypertension (systolic BP ≥ 140 mm Hg or diastolic BP ≥ 90 mm Hg), prehypertension (systolic BP 120-139 mm Hg or diastolic BP 80-89 mm Hg), and hypertensive crisis (systolic BP ≥ 180 mm Hg or diastolic BP ≥ 110 mm Hg) were calculated and compared with the US adult population using standardized morbidity ratios (SMRs). Most participants were male (N = 1317, 94%), White (N = 1303, 93%) and non-Hispanic (N = 1316, 94%). Thirty-one percent (N = 440) of participants had BP in the hypertensive range and 87% (N = 1215) were overweight/obese. Twenty-four participants (2%) had a BP reading consistent with a hypertensive crisis. Prevalence of obesity (52%, SMR = 1.52, 95% confidence interval = 1.41-1.64) and BP consistent with hypertension (31%, SMR = 1.60, 95% confidence interval = 1.45-1.76) was higher than the US adult population.The prevalence of obesity and BP consistent with hypertension in this population of coal miners is substantial, indicating a need for cardiovascular health interventions in coal mining communities.

Airborne fungal species associated with mouldy and non-mouldy buildings

Effects of air change rates, humidity, and air velocity
Several studies have shown an association between dampness and health issues like headache and asthma. To better understand the exposure risk of fungal growth in buildings this study investigates the release of fungi from gypsum boards infested with fungi from a moisture-damaged house. Further, the composition and concentration of fungal species in indoor air of five non-moisture-damaged homes are analysed, and the ratio between species associated- and not associated with moisture-damaged buildings are related to air change rate (ACR) and relative humidity (RH). The air velocity near the surface of the gypsum boards in combination with the changes in sampling time influenced the particle release rate. After 8 h particles were still released, and more species were released during 8 h with low air velocity than during 15 min with high air velocity. More fungal species and a higher release rate were found from damp surfaces with substantial growth than from gypsum boards dried out before they were totally colonized. In the five homes ACR and RH had a significant influence on the fungal species composition. Thus, a low ACR and a high RH were associated with increased ratio of species associated with moisture-damage relative to species not associated with moisture-damage. In conclusion, increasing the ventilation and reducing the RH of the indoor air will have a beneficial effect on the airborne species composition. Further, fast action by drying out a fungal infestation has a positive impact on the exposure risk in terms of exposure level and species composition.

Risques biologiques infectieux en animalerie de compagnie

Plusieurs zoonoses (bactériennes, virales, parasitaires, mycosiques) peuvent être transmises à l'Homme par les animaux de compagnie. Cependant, une enquête de la Mutualité sociale agricole (MSA) a mis en évidence une méconnaissance par les animaliers des risques encourus. À partir de ce constat, une recherche bibliographique et une étude de poste dans une animalerie de compagnie ont permis de réaliser un état des lieux des risques et des mesures de prévention afin de proposer des pistes d'amélioration. Les résultats montrent qu'il n'est pas toujours facile, dans ce milieu particulier, de faire respecter les mesures de prévention et que des actions d'information sont nécessaires. Une attention particulière doit être portée aux femmes enceintes au contact des chats et des rongeurs, ainsi qu'aux salariés travaillant au contact des oiseaux, devant les risques de toxoplasmose pour les premières, et d'ornithose pour les seconds.

Aérosols semi-volatils

De l'identification au prélèvement
Des études récentes concernant les aérosols semi-volatils ont révélé des interactions entre les particules et les vapeurs. Encore faut-il être capable d'identifier le caractère semi-volatil d'une substance pour développer une méthode de prélèvement et d'analyse prenant en compte les deux phases, particulaire et vapeur. Cet article a pour but de donner une définition adaptée de ce qu'est un aérosol semi-volatil et d'appliquer cette définition à des composés dont les méthodes de prélèvement et d'analyse ont été développées récemment à l'INRS.
