About us
The Hydrotox GmbH was founded in 1989 as a contract research laboratory and consultancy for assessing chemicals and mixtures by means of biological test systems. For this, internationally accepted and standardised test methods for the assessment of biodegradability, ecotoxicity and genotoxicity are applied.
The focusing of our business strategy is based on:
- Contract research related to environmental topics for industry and public authorities
- Routine testing in compliance with the principles of "Good Laboratory Practice" (GLP)
The Hydrotox team consists of biologists, chemists, hydrologists, environmental engineers and technical assistants. We have an extensive expertise in studies with chemicals, pharmaceuticals, biocides, detergents, lubricants and cosmetics as well as other products and environmental samples. The methods applied by Hydrotox GmbH are adapted and improved continuously to the current standard of knowledge and are validated by participation in international ring tests. All studies are performed according to the principles of GLP or ISO 17025 which assures our high quality and comparability of the results. The combination of laboratory and advisory services is an essential element of the business of the Hydrotox GmbH.
Research
On behalf of renowned institutions such as the Federal Environment Agency, the Federal Institute for Occupational Safety and Health, the Federal Ministry of Education and Research, the European Commission and industry, Hydrotox contributes to the acquisition of scientific knowledge and the protection of the environment. The results of this research are published in national and international journals as well as on the websites of the project sponsors to ensure broad accessibility and transparency.

Quality Management and Certification
Good Laboratory Practice (GLP)
By establishing the principles of Good Laboratory Practice (GLP), a uniform quality system is available and applied for the non-clinical safety testing of pharmaceuticals, pesticides, cosmetics, veterinary drugs, food and feed additives, and industrial chemicals.
ISO 17025
Additionally to the GLP principles, a quality management system according to ISO 17025 has been established in 2002.

Membership and committees
We are members in the
-
Society of Environmental Toxicology and Chemistry (SETAC Europe)
-
German Chemical Society (GDCh) (section ecotoxicity and water chemistry)
-
European Environmental Mutagen Society (EEMS)
