“At night, in the area of ​​treatment facilities of the Municipal Unitary Enterprise“ Industrial Association of Water Supply and Wastewater Disposal ”(MUP POVV) in the Metallurgical District, a strong salvo of hydrogen sulfide occurred,” TASS quotes Bezrukov as saying.

As noted, mobile laboratories were dispatched to the site, which confirmed a strong excess in the area of ​​MUP POVV.

As the Deputy Minister specified, in this regard, in some districts of the city, there may be a strong smell of hydrogen sulfide or similar to the smell of "sewage".
