LimCo International:

Scientific consulting regarding water quality issues

As experts in ecotoxicology we are your counterpart for all issues around water, water quality and innovative water management. Whether you are from a company, industry, public institution, agency, authority, action group or an educational institution, LimCo International supports you individually and performs tests of your water samples.

We also evaluate your personal exposure towards chemicals with risk assessment, water analyses and tests. We advise you on how to reduce your exposure and propose less toxic alternatives as well as environmentally friendly handling with harmful substances.

We always pursue the goal to protect nature and the environment for future generations.  Therefore, we are also active in career coaching in the environment sector. Moreover, we offer our expertise and experience to design future-oriented curricula and new professions in the water sector.

With our new in-situ GamTox field test we bridge between science and practice and easily demonstrate water quality assessment, in situ biomonitoring and the value of clean water for everybody, including pupils and students, directly outside in nature.

GamTox Test

In-situ field test for toxicity evaluation in small streams

In the framework of our InterReg IV project (2011-2013) we developed and validated our GamTox field test in Germany and Switzerland. GamTox detects pollution pulses in agricultural areas, vineyards, below waste water treatment plants and industries. GamTox allows an ecologically relevant ecotoxicological in-situ bioassessment in small streams. As it is easy to perform, it is excellently suited in school teaching, universities, authorities and NGOs.

GamTox has already been used successfully in the following settings:

Water quality bioassessment in agricultural areas (e.g. Germany, Switzerland, Lake Constance-region, NRW, Bavaria)
Water quality survey in metal- and coal mining areas (e.g. Portugal, Germany)
Scientific research projects
