Reason is simple, Example As value is 0.01 mg/l or 10 ppb, later is more representable for parameter with low range of std limit. I hope you are clear. Thank you 😊

The way to obtain ideal is best when BIS standards is use, I belive you are aware as mentioned in the video.However, with using other standards the problem is with obtaining ideal value, so it might be 0 or it might be some value if the standards you adopted do have lower and upper limit. This is situation with other standards.However, another option you can confirm is by cross check other publications in your respective country's working on Heavy metals, even from there you will get some clue too.
