How should an efficient and high-tech monitoring of environmental pollution levels be built?

In July 2022, one of the largest rivers in Poland was polluted by a discharge of warm, saline, highly oxidised water and possibly also by still unknown toxins.

Almost the entire river biosphere died out. Now (August 2022), the rotting remains of dead fish have caused secondary decay processes and a decrease in oxygen. Previously, so-called golden algae, which are harmful to the biosphere and form strong blooms in warm and saline water, have also developed. This is one of the biggest ecological disasters in Poland. The strangest thing is that anglers had already signalled at the end of June that the ecosystem of the Oder River had been severely disrupted by unknown substances released into the river. However, the services responsible and subordinate to the government, the company managing the state of rivers in Poland, i.e. Wody Polskie (Polish Water), started to do anything about it to save the river's ecosystem only in mid-August 2022.

Before that, anglers had already managed to catch tens of tonnes of dead fish.

Now many citizens are trying to answer questions:

Why did the river's environmental monitoring system not work?

Why have the institutions of the state acted with such a long delay when it comes to saving the river's ecosystem?

But this is just one of many examples of environmental disasters still occurring in various parts of the world.

In view of the above, I address the following questions to the esteemed community of scientists and researchers:

How should an efficient and high-tech monitoring of environmental pollution levels be built?

How should an effective monitoring of the state of the environment be developed in order to significantly prevent still occurring environmental disasters?

How should an efficient monitoring of the state of the environment be built, including monitoring of the level of pollution of the terrestrial or aquatic environment (rivers, lakes, seas, oceans)?

How should an efficient analytical system for the state of the terrestrial and/or aquatic environment be built?

What ICT information technologies, Internet, Industry 4.0, satellite, etc. could be useful to improve environmental condition monitoring?

How should an efficient system of systemic environmental risk management be built?

What do you think about this topic?

Please reply,

I invite you all to discuss,

Thank you very much,
