The Seveso disaster is widely regarded as one of the most severe environmental catastrophes globally, often compared to Chernobyl for its regional impact, and it marked a pivotal moment in raising awareness about environmental protection and industrial safety across Italy and Europe.
The incident, which occurred on July 10, 1976, at 12:28 p.m., was caused by an uncontrolled reaction inside a chemical reactor, which released a toxic dioxin cloud into the atmosphere. More than 200 individuals, primarily children, developed serious skin conditions, and in the decades that followed there was a rise in cancers—especially of the pancreas and bladder—as well as leukemia. Environmentally, the disaster caused the death of thousands of animals, the destruction of vegetation, and required the removal of heavily contaminated soil. Together with the Toulouse accident, this event prompted the adoption of the “Seveso Directive” (82/501/EEC and later amendments), a European framework establishing strict safety measures to prevent major industrial accidents.
Atmosphere has thought that it's important and appropriate to remember such an event: although it was a dramatic situation, the scientific community has learned a great deal, both in terms of understanding dioxin itself as a chemical compound and its impact on health and the safety of high-risk facilities. For this reason, this webinar would like to remember that event and a lot of information and facts occurred after.
On the behalf of the speakers, I would like to extend sincere gratitude to all participants, and partners whose contributions make this webinar possible along with my personal gratitude to all speakers for their kind participation. May the exchange of ideas and experiences during this event inspire new collaborations and guide us toward concrete actions for a safe and greener future.
