It is estimated that more than 3.6 million workers in Europe are exposed to diesel emissions. Occupational exposure takes place mainly in mining, construction, transport, agriculture and other activities using diesel vehicles and equipment. New data on the carcinogenicity of diesel engine emissions and the change in their classification from potentially carcinogenic (Group 2B) to carcinogenic (Group 1), as well as the high number of workers exposed to these types of chemical pollutants, highlighted the need to set occupational exposure limits for emissions diesel en...

The current level of accountability is set by the legislation in force, the active involvement of civil society, better informed and more confident in its role and voluntary adherence to principles of social responsibility. The risk is related to the level of uncertainty, and this is a ubiquitous component of research. Transfer of research results into production can mean risk transfer and potentiation. Risk management is therefore a challenge for both academics and economics. Examples, especially on substances and preparations, but not only, illustrate the current difficulties to manage significant risks, like those to worker health and safety, product safety, environmental protection. On the other hand, risk-taking, if related opportunities, can lead to competitive advantages, which may be determinant to decision-making.

Microbiological air purity was measured with a SAS-100 Surface Air System impactor. The fungal contamination was observed in all 54 rooms where we made determinations. The highest levels of fungal were recorded at rooms with hygroscopic patrimony objects, eg carpets, chairs, upholstered chairs, books etc. The most species identified included under common allergens: Aspergillus, Penicillium, and Mucor. There fungal species belonging to the genus identified in this study, can trigger serious diseases museum workers, such as for example Aspergillus fumigatus, known allergies and toxic effects that may occur. In some places of the museum, occupational exposure limit values to fungi present in the air in the work environment, recommended by the specialized literature, have been overcome.

Beside this, large quantities of paper are rapidly damaged by biological attacks following natural disasters and improper storage conditions. The treatment of paper documents with ionizing radiation can be used for mass decontamination of cultural heritage items but conservators and restaurators are still reserved because of the radiation induced ...
