Unit 4.3 works in the field of toxicology. This concerns the science of poisons. The unit analyses and evaluates experimental data on the hazardous properties of substances. It focuses on these effects of hazardous substances that have a specific impact on the health risk in a workplace. It describes the risk-related, hazardous properties of a substance. Is it toxic to the liver? Does it cause cancer?
Knowledge about the hazardous properties of substances is necessary but not sufficient for the derivation of occupational exposure limits and the assessment of health risks. Our work centres around the assessment of the toxic potency of hazardous substances. Are small doses of this substance already liver-toxic? Is this a particularly potent carcinogenic substance?
The unit is integrated into the division that deals with hazardous substances. It implements the work results of different units: the unit 4.3 characterises the health risks of hazardous substances based on its toxicological evaluations concerning the effect and toxic potency of substances and relates this to the inhalative and/or dermal exposure estimates at workplaces determined by other units.
The tasks are:
The activities for securing our competence regarding toxicological and risk-related methods:
