I’m puzzled: after fire accidents occur in our country, are toxic substances never detected in the air?

After seeing the fire at the warehouse in Tianjin Dagang, I was moved to write something. Those who understand environmental protection, please explain: were the toxic substances blown away by strong winds, or are there some regulations that prevent the detection of toxic substances in the atmosphere? . . . . . . . . .
It mainly depends on the sensitivity of the testing instruments; those with high sensitivity are usually imported and expensive, so environmental monitoring departments do not equip themselves with them.
But if you are at the scene, you can generally sense it through your nose, respiratory tract, eyes, and skin; therefore, the human senses are the most sensitive detection instruments. The disadvantages are the difficulty in quantitative detection and evidence retention.
I’m not sure if it’s been mentioned abroad that it has been detected; that’s what this question is asking
We are a powerful country; one poison can counteract another. When poisonous gases encounter our country, their toxicity disappears and they vanish. Long live China! Long live China! Tianjin loses one year old
I don’t know. Anyway, from what I’ve observed, in the official statements issued after fire accidents, the vast majority claim that no pollution occurred and that no toxic substances were detected in the air – which isn’t scientific. Toxic substances must be produced, but why can’t they be detected?
It cannot be detected because it has been diluted; testing can only be done on the ground. Not all of the toxic and harmful substances in the smoke from a fire drift away with the smoke. As long as the local population is not affected, that’s sufficient. Problems are relative – one fire in Tianjin shouldn’t keep so many people across the country worried. After all, no one wants fires to occur
It is common to see news reports stating that after an accident of XX type occurs, environmental protection agencies go to the scene immediately to test the air quality. The test results show that the accident did not cause pollution in the surrounding area, and no secondary disasters occurred.
