    Abstract The working group “Analyses in Biological Materials” of the Permanent Senate Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area verified the presented biomonitoring method. The analytical method described herein permits the sensitive determination of both unmetabolised 1‐bromopropane and 2‐bromopropane in urine. Prior to the determination using GC‐MS in the Single‐Ion‐Mode (SIM), the analytes are extracted and enriched using Headspace Solid Phase Dynamic Extraction (SPDE). To this end, the urine samples are incubated at 50 °C and the analytes are extracted from the gas phase using SPDE. The headspace extract is then injected into the gas chomatograph for separation and mass spectrometric analysis. Calibration standards are prepared in urine and processed in the same way as the samples to be analysed. Deuterated benzene is used as the internal standard (IS).

    Abstract The German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area has evaluated copper (CAS No 7440‐50‐8) in 2016. Due to the homeostatic regulation of copper there is no correlation between copper exposure in air and copper in blood or urine. Neither increased inhalation exposure higher than the MAK value of 0.01 mg copper/m3 nor increased oral supply lead to an increase of copper in blood or urine, even if first signs of exposure such as increased C‐reactive protein (CRP) are observed. An additional occupational burden cannot be differentiated from physiological levels of copper. Therefore, the evaluation of a biological tolerance value (BAT value) and a biological reference value (“Biologischer Arbeitsstoff‐Referenzwert” (BAR)) for copper and its inorganic compounds is not indicated.

    Abstract The working group „Analyses in Biological Materials“ of the Permanent Senate Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area verified the presented biomonitoring method. The analytical method described hereinafter permits the simultaneous determination of the following unmetabolised aromatic compounds in urine: benzene, toluene, o‐xylene, m‐xylene, p‐xylene, ethylbenzene, styrene and isopropylbenzene (cumene). Prior to the determination of the analytes by GC‐MS, the analytes are extracted and enriched using ITEX (In Tube Extraction) or SPDE (Solid Phase Dynamic Extraction). To this end, the urine samples are incubated at 50 °C, the analytes extracted from the gas phase and then the enriched analytes are transferred to the gas chromatograph and analysed using mass spectrometry. Calibration standards are prepared in water and processed in the same way as the samples to be analysed. Deuterated benzene is used as internal standard. The method was extensively validated and the reliability data were confirmed by an independent laboratory, which has established and cross‐checked the whole procedure.

    Abstract In 2017, the German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area has re‐evaluated the biological tolerance value (BAT value) for aluminium [7429‐90‐5]. Available publications are described in detail. The BAT value of 60 µg aluminium/g creatinine evaluated in 2009 was based on the linear correlation between external and internal exposure. The aim of this re‐evaluation was the derivation of a health‐based BAT value considering the most sensitive critical effect of aluminium, the neurotoxicity. For this purpose, the available studies of aluminium‐exposed workers were taken into account, when the internal aluminium exposure as well as the occurrence of subclinical neurotoxic effects were determined. The effects had been measured with standardised neuropsychological test procedures. From these studies, a no observed adverse effect level (NOAEL) of 50 µg/g creatinine for the occurrence of subtle neurotoxic effects of humans was estimated. Therefore, a BAT value of 50 µg aluminium/g creatinine was evaluated. Sampling time for long‐term exposures is at the end of the shift after several shifts.

    Abstract The German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area has re‐evaluated the maximum concentration at the work place (MAK value) for dipropylene glycol has been set at 100 mg/m3 for the inhalable fraction, considering the endpoints respiratory tract irritation and systemic toxicity as well as absorption through the skin. A 2‐year drinking water study with rats shows a NOAEL for focal inflammation of the liver in males of 115 mg/kg body weight and day and a NOAEL for olfactory epithelium degeneration in males and females of 470 and 530 mg/kg body weight and day, respectively. This raises the question, whether the olfactory epithelium could also be a local target tissue after inhalation. Inhalation studies with dipropylene glycol are not available. The substance shows very slight irritation of skin and eyes, if any. Thus, there are no indications of a potential local irritative effect to the upper airways. Therefore, the MAK value of 100 mg/m3 derived from systemic effects is validated. As systemic effects are critical, the assignment to Peak Limitation Category II and the excursion factor of 2 are retained. A recent in‐vitro study with human skin shows that skin contact does not contribute significantly to systemic toxicity and the former designation with an “H” notation is withdrawn.

    Abstract Tropenol ester is a highly toxic anticholinergic substance and an intermediate used in industrial production of the bronchodilator tiotropium bromide. The aim of this study was to systematically test workers involved in its production for tropenol ester in urine to identify any exposure pathways and define additional preventive measures. Twelve workers performing tasks involving potential exposure to tropenol ester were repeatedly monitored at the end of each production cycle. Medical exams revealed no symptoms of acute poisoning with tropenol ester, but biological monitoring of urine showed 36 positive findings in 79 samples, with tropenol ester concentrations ranging between the detection limit of 54 pg/mL and 2160 pg/mL. We managed to establish the cause of only one positive finding, which was a hole in a protective glove, whereas the rest most likely occurred due to human error. Because of this, the plant decided to modify the production process by replacing tropenol ester with a safer intermediate. While it is the safest course of action, there where it cannot be taken, biological monitoring can be very helpful in raising awareness about exposure to toxic substances, including the new ones that have not been studied for their adverse potential.
