Toxic disinfection?

Today, we went playing Padel again 🎾 At arrival we noticed that the sports centre had updated the disinfection procedure: there is a large blue mat at the entrance to the outdoor area which is covered in disinfection spray. You have to walk over the mat to disinfect your shoes 👟

☠️ BUT: next to the mat we noticed 2 dead birds 🐦 🐦!

Question: 📌 How toxic is the spray to the nature? How toxic is the spray for humans? This was scary! 📌
