Microplastics and freshwaters: main results of the life project Blue Lakes

AI summary Read the abstract

Researchers reported the main results of the EU LIFE BlueLakes project, which used an integrated governance, monitoring, and awareness approach to assess and reduce microplastic pollution in five major lakes across Italy (Garda, Bracciano, Trasimeno) and Germany (Constance, Chiemsee).

Study Type Environmental

The EU LIFE BlueLakes Project tackles the microplastic problem in Italian and German lakes using an integrated approach combining actions of governance, training, technological and monitoring tools, and information and awareness-raising aimed at institutions, relevant subjects and citizens. Main project's actions were performed in Garda, Bracciano and Trasimeno lakes in Italy and in Constance and Chiemsee lakes in Germany. The main aim of LIFE Blue akes was: 1) to guarantee the reduction and prevention of microplastics in the lakes providing operative tools for the monitoring of inland waters and the treatment plants, raising the awareness of all the stakeholders, 2) to provide support for local stakeholders located near the main Italian and German lakes tackling the problem of microplastics based on participation in defining good management practices, 3) to improve the current legislative framework, influencing the policy agenda at Italian, German and European level, 4) to monitor the wastewater treatment plants and 5) to develop a standardised protocols for the designing and carrying out of seasonal microplastic monitoring programmes in the freshwater (lakes and rivers) and wastewater treatment plants. The project ended in September 2023 and one of the most relevant results concerns the development of a protocol regarding sampling, sample processing and characterization of the microplastics found. The protocol will be used at a national level by the Regional and Provincial Environmental Protection Agencies (ARPA and APPA) to carry out checks and monitoring on surface waters. The monitoring of the lakes has demonstrated how widespread and abundant microplastics are, concentrations of up to over 500,000 MPs/km2 have in fact been found in some lakes. The developed methods were used and validated in another 4 bodies of water - Lake d'Orta (sub-alpine); Lake Ridracoli (artificial basin), Lake Scanno (mountain), Lake Cavazzo (karstic). Other results will be reported in the paper. Also see: https://micro2024.sciencesconf.org/559596/document

Microplastic sources and distribution dynamics across contrasting anthropogenic settings: implications for lake management

AI summary Read the abstract

Microplastic particles have emerged as a pervasive pollutant in lake ecosystems, with sources and distribution patterns varying significantly across different anthropogenic settings, affecting ecological processes and human health. Understanding how land use and human activity influence microplastic loading and spatial distribution in lakes is essential for developing targeted management strategies.

The emerging issue of microplastics: ongoing investigation in water and sediments of subalpine lakes

AI summary Read the abstract

This Italian study identified microplastics in subalpine lakes and characterized their polymer types and abundance, adding to evidence that microplastics have reached even remote freshwater ecosystems far from industrial centers. The findings underscore the ubiquity of plastic contamination across diverse freshwater environments.
