  Abstract: In recent years, there has been a rise in cyanobacterial blooms, and climate warming is believed to be a key driver sustaining these changes. Climate change may affect the geographic distribution of potentially toxigenic species and cyanobacteria, leading to the appearance of new threats in previously unexposed areas. Recently, the potentially toxic cyanobacterium Raphidiopsis (Cylindrospermopsis) raciborskii, known for forming blooms, has increased its presence, particularly in temperate regions. In this work, we expanded the knowledge about the distribution of R. raciborskii in Northern Italy. Specifically, we reported new observations recorded during the last decade based on investigations carried out in the framework of scientific and government monitoring and large biogeographical surveys carried out on the whole Alpine Space area. The detection of R. raciborskii in Northern Italy highlights the importance of closely monitoring freshwater quality and implementing measures to prevent the spread of harmful organisms.

Cyanobacterial blooms in the Po River basin and the eastern Alps

  Abstract: In this paper, we briefly describe episodes of cyanobacterial blooms that have occurred in lakes of northern Italy since 2000. In addition to listing the species involved in these blooms, we provide information on the trophic and ecological status of the water bodies and the presence of algal toxins. Furthermore, we report an example of a risk assessment effort aimed at developing a quality control system for water intended for human consumption. The use of high-frequency monitoring techniques, integrated with predictive modelling, remote sensing, and molecular analysis for species identification, is becoming increasingly important in the context of the effects of ongoing climate change.

Safety of water for human consumption: a case study from Northern Italy
- Authors: Mariano Nasello, Eleonora Masala, Gaia Villa, Anna Di Lauro, Samuele Peraboni, Simona Vercelloni, Franca Facchini, Anna Molinari, Nicoletta Castelli
  Abstract: Water is essential for health, and climate change can compromise its quality. The Local Brianza Health Protection Agency (ATS) has initiated a biennial monitoring project of water supply sources to ensure safe and clean water access, in line with the United Nations (UN) Agenda 2030. The project has identified vulnerabilities in the water supply chain, finding the presence of cyanobacteria in 19.7% of samples. Risk assessment results show that climatic conditions could influence the vulnerability of sources.
