Environmental protection plays an important part in a product‘s entire life cycle. Dealing with the negative effects on water, soil, and air is an important factor in this context and requires extensive studies, as early as in the chemicals‘ approval stage. In addition, biotests are an integral component in the evaluation of the potential eco-toxic effects of various products and the biological quality of eco systems.

SGS INSTITUT FRESENIUS offers a varied portfolio of basic bio test assays in accordance with national and international regulations. Many years of expertise in dealing with problematic substances allows for tackling of difficult tasks such as the evaluation of volatile, coloured, or opaque substances. All product relevant studies can also be performed under GLP conditions.
