The M.F.N.M. was sold and became S.C. Sometra S.A. with the hope that the foreign director, which bought the factory, will reduce the concentrations of inorganic lead and other evacuated toxins so they fit the normal limits.
     At first sight you would say that the problem was successfully solved but the situation is far from this. It becomes more clearly that the plant “Carbosin” was making a pollution called optical pollution, which meant that the black smoke was indeed dangerous but not so like the high inorganic lead concentrations which we know. In winter, because of the plant Carbosin, the snow would be sometimes black and in the rest of year the trees and houses were covered in black.
     Through the years the authorities supervised the value of lead and cadmium from the surface waters, fountains but also from the potable water ellaborated from the surface

water source in Copsa Mica.
     So the authorities were suprized to notice that in 1978 the values were 6,6 times than normal, 4 times in 1989 and 1992, 3,8 times in 1985, 3 times in 1982 and 2 times in 1986.
This dates were for lead, and for cadmium there was a record in 1979 of 276,6 times the normal limit. There test were ellaborated from the river Tarnava Mare, near the town Copsa Mica.

The principal toxins which affect the atmosphere from Copsa Mica are: lead, cadmium, SO2 and dioxide of azote.
