Airborne microplastic particles – endangering human health – in indoor and workplace atmosphere along with their concentrations and microbiological impacts, will be identified as well as harmful substance concentrating effects of waterborne microplastics and the toxicological impacts of microplastics emitted into the environment during wastewater treatment processes will be assessed and identified in the context of the project entitled "Development of multiparameter testing systems for the analysis of the environmental impacts of microplastics" – funded by a grant of a total of HUF 624,632,580 – with the involvement of several universities, one independent testing laboratory and highly reputed experts.
