Abstract: A system for the abatement of noxious emissions from an industrial or nuclear power plant or the like in the event of accident includes a structure for impermeabilization of the ground, which extends at least in an annular area that surrounds the plant, a plurality of water-sprinkling towers, which are arranged around the plant and sprinkle water in the atmosphere, preferably added with chemical and/or biological and/or mineral substances, and a peripheral collection structure, configured for receiving water withheld by the impermeabilization structure.
