My family lives near the power plant, and there are six big chimneys smoking. Is it poisonous?

Six are very thick, which should be cooling towers, which is nothing, but one or two should be thinner, but much higher, and that is the chimney. Of course it's poisonous. Although the environmental protection department has tested it, the incidence of cancer among residents living near power plants (mainly thermal power plants) has actually increased significantly. If possible, let's move out.
