Occupational exposure to Cr(VI) in Finland in 1980-2016 and related lung cancer risk assessment.

Occupational exposure to hexavalent chromium [Cr(VI)], a known lung carcinogen, remains a relevant concern. When performing exposure assessment for risk assessment, biomonitoring is an important tool, reflecting actual internal exposure of workers. Here, we present total urinary chromium (U-Cr) biomonitoring data from several occupational sectors, spanning 1980-2016 (n > 42,000).

Setting up a collaborative European human biological monitoring study on occupational exposure to hexavalent chromium.

The EU human biomonitoring initiative, HBM4EU, aims to co-ordinate and advance human biomonitoring (HBM) across Europe. Within its remit, the project is gathering new, policy relevant, EU-wide data on occupational exposure to relevant priority chemicals and developing new approaches for occupational biomonitoring. In this manuscript, the hexavalent chromium [Cr(VI)] study design is presented as the first example of this HBM4EU approach.

Exposure to flame retardants in electronics recycling sites.

Waste electrical and electronic equipment (WEEE) contains various hazardous substances such as flame retardants (FRs). Inhalation exposures to many FRs simultaneously among WEEE recycling site workers have been little studied previously. The breathing zone airborne concentrations of five brominated FR compounds tetrabromobisphenol-A (TBBP-A), decabromodiphenylethane (DBDPE), hexabromocyclododecane, 1,2-bis(2,4,6-tribromophenoxy)ethane, hexabromobenzene, and one chlorinated FR (Dechlorane Plus®) were measured at four electronics recycling sites in two consecutive years.

Airway exposure to silica-coated TiO2 nanoparticles induces pulmonary neutrophilia in mice.

The importance of nanotechnologies and engineered nanoparticles has grown rapidly. It is therefore crucial to acquire up-to-date knowledge of the possible harmful health effects of these materials. Since a multitude of different types of nanosized titanium dioxide (TiO(2)) particles are used in industry, we explored their inflammatory potential using mouse and cell models.

Self-reported occupational health hazards and measured exposures to airborne impurities and noise in shoe repair work.

The authors identified occupational risk factors of shoe repairers and measured their exposures to organic solvents, dust, chromium, degradation products of synthetic shoe materials, and noise. Exposures were measured in 11 shops selected from the workplaces of 82 repairers who responded to a questionnaire about their work environments. The questions dealt with, e.
