Environmental Toxicology
Econetta conducts studies on physico-chemical properties, toxicological impacts on aquatic environments, and biodegradability, serving both regulatory needs and the development of active ingredients and products.

Who we are
We focus on quality. Our environmental toxicology laboratory is one of the few in Switzerland certified for Good Laboratory Practice (GLP) and accredited under ISO/IEC 17025. We assist you in generating high-quality, reliable and robust test data for non-clinical safety studies, facilitating registration and approval processes.
What we do
We offer a thorough analysis of the potential toxic effects of your substances, along with their physico-chemical properties. Our environmental toxicologists conduct a wide array of studies on aquatic toxicity and biodegradability according to international OECD test guidelines. Below is an overview of some of our services:
OECD-Tests
- OECD 105: Solubility in water
- OECD 111: Hydrolysis (as a function of pH)
- OECD 107, 117, 123: Distributional coefficient log POW
- OECD 121: Adsorptionskoeffizient log KOC
- DIN 38 414-S9: Chemical Oxygen Demand
- OECD 201: Growth inhibition of green algae
- OECD 201: Growth inhibition of cyanobacteria
- OECD 202: Acute immobilisation in daphnia
- OECD 203: Acute toxicity to fish
- OECD 211: Chronic toxicity to daphnia (reproduction)
- OECD 221: Growth inhibition in duckweed
- OECD 209: Bacterial toxicity
- OECD 301A: DOC Die-Away
- OECD 301B: CO2 Evolution
- OECD 301C: Modified MITI Test I
- OECD 301D: Closed Bottle
- OECD 301F: Manometric Respirometry
- OECD 302B: Zahn-Wellens
- OECD 302C: Modified MITI Test II
- OECD 311: Anaerob degradability
In addition, we cooperate with other institutes to offer further standard test procedures:
- OECD 236: Acute toxicity to fish embryos
- OECD 249: Fish Cell Line Acute Toxicity
- OECD 423: Acute Oral toxicity
- OECD 439: In Vitro Skin Irritation
- OECD 471: In Vitro gene Mutation
The study design can be flexibly adapted to your individual requirements, such as:
- Biodegradability (302B + CO2)
- Biodegradability (CO2 development only)
- Flocculation/Sedimentation
- Sorption an activated carbon
What products we test
Our team possesses extensive expertise in analyzing a diverse range of substances, including active ingredients and products from pharmaceuticals, pesticides, biocides, and industrial chemicals. Our analytical experts specialize in complex substances and mixtures that may be poorly soluble, volatile, or colored.
At a Glance
- Chemicals
- Pharmaceutical Products
- Plant protection products
- Cleaning agents/detergents
- Hygiene products
- Lubricants
- Sewage
- Mixtures, UVCBs
Other services
In close cooperation with our colleagues in the field of product compliance and sustainability, we also provide the following services:
At a Glance
- REACH
- Safety Data Sheet (SDS)
- European Ecolabel
Where We Were Active
Over the years, we have conducted numerous tests for clients across various industries in accordance with OECD guidelines, delivering essential data for regulatory purposes. Our work has provided valuable insights into the environmental impact of your products, their effects on aquatic ecosystems, and their physico-chemical properties.
Detecting pesticide emissions at production sites
- Developed a comprehensive investigation program to evaluate the treatability of pesticides.
- Systematically executed the research program.
- Tested 54 active substances across 83 commercially available plant protection products.
- Identified the most effective process combinations to reduce active ingredient concentrations and minimize environmental impact.
