@oopsie better known to concerned fraternity question .UPSC gives chance to students belonging to all fields
@5HT Lethal Concentration - an overview | ScienceDirect Topics - This article says that for CO to be lethal, a person needs to be exposed to >1000 ppm for at least an hour. Which is technically a small quantity, but not so small when you compare it with what will be emitted by industrial processes into the environment. I couldn't find the exact number for copper plants, but it won't be this high.
You can compare it with this - Carbon Monoxide | UCAR Center for Science Education . It says that in areas with heavy traffic, CO levels can rise to as high as 50 ppm. Emissions by an industrial unit into the environment might be more/less than this. But it certainly won't be 20X(ie 1000)

CPCB norms for copper smelting industry
If there was concern of emission of CO in the environment in lethal quantity, CPCB must have added.
gaurav0412198925394,@prachimalik1121311 it seems more of a test of common sense. If CO from emissions into environment could have killed people, then people would have dropped dead sitting inside or outside some of the public transportation buses considering how much of black smoke comes out of it
@oopsie sorry lessons of common sense I am not ought to learn From you (not being rude ) but to prove your answer right this is a very wrong way and if you are so sure kindly prepare for mains
I mean you have source to backup your answer fine pretty good
All the best for mains
plmokn25688524,@oopsie kindly apply common sense and see if you are passing or not and prepare for mains😂😂😂it is a matter of common sense that debate here won't make my answer wrong neither your Right (applies on Me too)
@prachimalik1121311 wow that escalated fast. sorry if i offended you somehow. i know tensions are running high and people are on edge. but i was just settling the question. It might be right for some, might not be for some
@prachimalik1121311 wow that escalated fast. sorry if i offended you somehow. i know tensions are running high and people are on edge. but i was just settling the question
"unsettling" the answer was more like it. Lol. Kidding.
keephustling,Vesuvius@Guesswhoshere lol
@prachimalik1121311 lethal is something that can directly threaten the life of people in the vicinity of the pollutant emitting industry. But i believe ultimately it is upsc which can decide on this matter as they have to release the results.
@prachimalik1121311 The simplest logic is copper ore is mainly pyrites, which is sulphur based. There can be emission of CO, no doubt but largely emission of SO2 will be the concern. Rest all depends on upsc.
@oopsie UPSC will settle us within a week don't worry bro
gaurav0412198925394,@Denisovan2019 and then nobody would be able to say anything. UPSC, supreme court se bhi badi body hai , jahan koi review petition nahin lagti. 😅
Denisovan2019,Udit_pathak@gaurav0412198925394 my simplest logic in 2019 was how come a secondary pollutant from 🤔burning of biomass I marked so confidently and gave myself a pat 😂😂😂wowwww ecology applied successfully but then when keys came
Denisovan2019,plmokn25688524@prachimalik1121311 UPSC is indeed like supreme court it works on precedent :p
prachimalik1121311,
@Denisovan2019 indeed
Guys, pollution is a negative concept. The spirit of the environmental legislations such as EPA, water act, air act etc is broadly to control pollution. It’s because pollution by nature is lethal. And the statement says, “ May release “ lethal quantities which is highly probable. Let’s not see lethal as an extreme word when pollution itself is a negative concept.
