Heat-related emergency medical service operations: the relevance of the heat definition.

Heat is associated with an increase in Emergency Medical Service (EMS) operations. However, different heat definitions in research, including outside air temperature (T), Heat Index (HI) and Universal Thermal Climate Index (UTCI), impair the assessment of heat onthe frequency of EMS operations. Therefore, this study aims to compare (1) the relationship between different heat definitions and the frequency of days defined as heat events, (2) the percentage change in the number of EMS operations per heat definition, and (3) the goodness of model fit of each heat definition.

Risky leisure noise exposure during the transition to adulthood and the impact of major life events - results of the OHRKAN cohort study.

Objective: To investigate the influence of four major life events (leaving home, full-time employment, married/cohabiting, parenthood) and socio-demographic variables on risky total leisure noise (TLN) during transition to adulthood with a special focus on visiting discotheques and listening to portable listening devices (PLDs).

Design: Longitudinal analysis of the OHRKAN cohort. Risky TLN covering 22 activities was defined as exceeding 85 dB(A) averaged over a 40-hour week.

Human biomonitoring follow-up study on PFOA contamination and investigation of possible influencing factors on PFOA exposure in a German population originally exposed to emissions from a fluoropolymer production plant.

Background: In the past, perfluorooctanoic acid (PFOA) was produced and applied as an emulsifier in a fluoropolymer production plant in the Altötting district, southern Bavaria (Germany). This chemical was released directly into the environment, resulting in the contamination of the local drinking water. During a human biomonitoring (HBM) survey in 2018, increased median PFOA blood serum levels, compared to a normally exposed control group with no known source of PFOA exposure from Munich, Germany, were detected in the resident population (23.

Risky listening behaviour to music via headphones and its determinants - 7.5 years OHRKAN cohort study.

Objective: To examine risky leisure noise exposure from listening to music via headphones and to identify potential determinants with special focus on portable listening devices (PLDs) among adolescents over a period of 7.5-years.

Design: Data were collected by questionnaires at four equidistant time points (O1-O4).
