Very well explained. I highly appreciate your efforts. Looking forward to many more lectures for other indices and also a separate lecture on Health risk assessment (carcinogenic and noncarcinogenic).
It means a lot to me Sir/Madam. Your kind words gave me more power. Your love and support is worth the time and dedication I put into it. Thanks a billion. I will look into your request. Thank you 😊
Omg... Masha Allah. Excellent explanation .... I was learning and watching videos on wqi and hpi... Bar far till today your video answered all questions that were not completely answered in other videos.... I am compelled to follow you!
I'm so grateful my work is having an impact all the way to Mexico 🇲🇽 as well. So grateful 🙏 for sharing your thoughts. Appreciate it very much 🙏 Thank you 😊
Thank you sir, for great session and initiative for helping students like us .Make lecture session on APTI (Air Pollution Tolerance Index) with theory to practical portion.
Thank you appreciate it very much. Yes, it is important. One simple reason is in mg/l values are minute but extended when converted to ppb. Check it when you compute your data you will.get clearer idea on why ok. Thank you 😊
The video is very easy to understand thank you for such a comprehensive video. How can i get a video like this one on how to calculate for ecological risk assessment?
Sure sure I'm happy to see your request I m so grateful However it will take time I believe you can understand Preparation is taking a lot of time However continue supporting this channel and will be there one day Thank you so much
This is of great help. Thank you. However, I was trying to get Wi for Fe, but not working because of zero highest permissible limit against 0.3 lowest acceptable limit. I would be glad if you can put me through.
Good Sir, I would like to ask how to calculate the removal efficiency of heavy metals from membrane filters if we get heavy metal data from AAS. The result of heavy metal data from AAS consists of concentration and %RSD. What is actually the data we have to input to Excel?
Thank you so much. The best is check research paper related to HM study in plants, if it is applied then yes otherwise other option might be there. Thank you 😊
I'm happy to know and hear that my video is helping. So I appreciate your kind words. Thanks 😊. With regards to the value format, use ppb as per the method. 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 😊
Well explained sir ..... Sir I m doing research on toxic matel determination in soil , Vegetable and water ...can I use this method to calculate HM in these samples.?? And one more thing we get the concentration and absorbance from AAS ....do it need further interpretation??
Thank you so much. Appreciate it very much 🙏. I'll suggest you kindly check if any other papers have use this for HM content in vegetable etc assessment. That is how we can assure its applicable besides applications in Water study. The data obtained (if needed check these before proceeding ahead )to be converted unit for easy further analysis. Thank you 😊 so much.
I ll kindly request you to re check the calculation carried out. Follow it step by step. However, slight possibility for high hpi values could be contributing by 1 or 2 paramters which are present beyond the limits. Thank you 😊
Thank you for the video, it's very educative but I have a question please. You converted the So and Ii values to ppb before using in the computation but the monitored value (Mi) was not converted to ppb from mg/l, and was used with other values converted already. They are not in the same unit with Sir and Ii, why? Thank you
Hello good day Sir. I find your lecture so educating and interesting. I have the following questions. If I want to make use of WHO, USEPA, NESREA standard how can I obtain the Si and Ii values because only one standard was given in your lectures in respect to the WHO and EPA standard ( I.e no acceptable Limit and permissible Limit) Thank you
Thank you so so much for your kind words and appreciation. I am really grateful 🙏. Yes, this is the issue with other standards due to non availability of AL and PL. Thank you 😊
Thank you for this great video Please sir, could you provide us with the source (How to cite -Citation-)of each of the guidelines you have shown in the Table shown at minute 15:36 Thanks
A great explanation. I have a question regarding ideal values and standard permissible values. I tried to find these values but didn't get them. how can I find Ideal values for WHO standard ??
Thank you so much Actually there are no pre determined given ideal values from WHO standard. You can try if your study is suitable using BIS standards. Thank you 😊
Thank you so much. Please Keep supporting for more. It depends on the standard limit adopted for the study. If BIS, I believe its 0, 0 and 0.1, respectively . Thank you 😊
@@JustLikeASteam I am adopting WHO standards, some of the standard limit values in your calculation are not correct as per 2022 WHO guidelines. According to 2022 guidelines I am using values 0.05, 0.01, 0.005, 2, 3, 0.3, 0.006, 0.5, 0.1 mg/l for Cr, Pb, Cd, Cu, Zn, Fe, Hg, Mn, and As respectively. I need ideal values for these all. Can you please help me out??
These 2 are different from one another. K doesn't meant same for everything everywhere. Ok. Follow the procedure according as per the method follow. Thank you 😊
I ll suggest you to please watch the video again. Your problem of negative sign is not a problem. Because role to negative is to ignore the negative signs. Even if you get -tive you have to ignore it ok. Thank you 😊
I really need to understand this one as you are so great but I could not find the ideal value in European standards. it is just available with the BIS standard. the European standard and WHO 2017 have the normal standard values for every heavy metals. Is there another way to put values in the column of the ideal values?
Very good, but I could not find the ideal value of As, Cd, Cr, Cu, Hg, Fe, Mn, Pb, Ni, Zn according to WHO 2017 or European standard. Can you please help with this? Thank you
Thank you so much. The standard limit you Ned are available in EPA website or Any other recommended agency you wish to incorporate in your study. Thank you so much again
@@JustLikeASteam Thanks for your swift reply. I found the standards for every metal, but it is mentioned in the video that we need the Ideal value. So, how could I find it based on the European standard. Your channel is amazing and your tutoring way as well
@@OMAR-ce1bj OH you referring to ideal values. 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. Ok Thank you 😊
Are the Si Value of Nickle and Cadmium right? If, so from where is it taken. Cause I followed your video, and failed to find the Si values of these two according to the BIS standard.
In mg/l value will be to large large for calculation Example 0.03 mg/l No seems not very ideal but if if the value is converted to ppb it give more clearer meaning. Thank you 😊 Continue supporting this channel 🙏 Thank you 😊
Yes you can refer any standard limit of your choice. But ideal will not be zero to all. On some case it might be 0 in some it will not. Check the step again in video ok please. Thank you 😊

Thank you, can I have the spreadsheet?
Would you kindly make a video on calculating health risk from metal elements? Many kind thanks in advance.
Thank you so much Sir. I really appreciate it. Thanks again
Thanks for the nice explanation! But, do we really need to convert the unit to ppb? What if we keep the units of all parameters consistent.

You took Mi in mg/L.. Is it ok ? or should we take it in ppb ?
Data originally might be in mg/l but need to be converted from mg/l to ppb . Ok
Thank you 😊
Thank you, I have seen your response here. My question is the same with Sawan Kumar Sahoo.
Thank you for this fantastic video
So so grateful for your kind compliment

The data of metals are in mg/L or ppb? plss help
20:05 onwards, I believe your question is answered. Kindly watch the video again. Thank you 😊
Please tell me one thing why we need to convert mg/l to ppb
In mg/l value will be to large large for calculation
Example 0.03 mg/l
No seems not very ideal but if if the value is converted to ppb it give more clearer meaning.
Thank you 😊
Continue supporting this channel 🙏 Thank you 😊
Ok understood that
Sir If I am using the WHO standard limit for calculating HPI. For that calculation ideal value is 0 for all metals. it is correct or not. pls tell me
Yes you can refer any standard limit of your choice. But ideal will not be zero to all. On some case it might be 0 in some it will not. Check the step again in video ok please. Thank you 😊
Can I use the HPI for the coastal water samples ( for the wastewater discharge into sea water ) assessment
Kindly verified it by checking the literature to confirm. Thank you 😊
HOW DO I REPRESENT THE RESULTS IN SPATIAL CONTEXT
I followed the same your steps, but I get a very high "HPI" value (Global) for some stations. Is this normal?
Best is just first see you specific location HM content is above the limit and if you then there is a possibility for such final output.Thank you 😊
