The Nature Research Centre joined the INSIGNIA-EU project aimed at monitoring environmental pollution by using honey bee colonies. The project involves all 27 EU countries. It is participated by 10 Lithuanian beekeepers who, acting as representatives of citizen scientists, will use in their apiaries different matrices for the collection of pesticides, heavy metals, volatile organic compounds and microplastics. Also, pollen samples will be collected for the assessment of plants visited by bees. On 18 April, the Nature Research Centre arranged a meeting of beekeepers participating in the INSIGNIA-EU project and familiarised them with the activities of the project.
