High concentration of Zinc above BIS limits (15 ppm) causes anemia, damage the pancreas, and decrease levels of high-density lipoprotein (HDL) cholesterol to human beings.

Permissible limit of Zn in potable water is 5 ppm. If more may cause Nausea,vomiting, loss of appetite, stomach cramps, diarrhoea and headaches. Also make lower immunity And low level of HDL cholesterols.

Dear Saxena ji please refer BIS 10500:2012 where the max permissible limit of Zinc is 15 mg/l not 5 mg/l.

In natural surface waters, the concentration of zinc is usually below 10 μg/l, and in ground waters, 10–40 μg/l . In tap water, the zinc concentration can be much higher as a result of the leaching of zinc from piping and fittings .
Permissible limit of Zn in potable water is 5 ppm (WHO).
Due to its nature as an essential trace element, oral uptake of small amounts of zinc is essential for survival. The recommended dietary allowance (RDA) for zinc is 11 mg/day for men and 8 mg/day for women ( Stromberg H.E and Agren M.S. Br. J. Dermatol. 1984)
Immediate symptoms after uptake of toxic amounts of zinc include abdominal pain, nausea, and vomiting. Additional effects include lethargy, anemia, and dizziness.

Supriya, Environmental Protection Agency, March 29, 2019 (EPA ) has stated that drinking water should contain no more than 5 ppm of Zinc in drinking water. For detail, please go through literature/online.

Zinc has a lower toxicity rate compared to lead. However, it can cause nausea, vomiting diarrhea and cramps in addition to a metallic taste in the mouth if the individual has a chronic zinc intoxication. There are discussions that the long period of water intake with the presence of zinc might trigger cancer, however, does not appear to be proven.

Calculation of active area of modified electrode by using Randles-Sevcik equation

I am going to calculate the active area of the modified screen-printed carbon electrode by using the Randles-Sevcik equation using 5 mM K[Fe(CN)6]3-/4- in 0.1 M KCl redox probe system. However, the diffusion coefficient of the redox probe system is not determined yet. I'm first conducting a series of experiments varying the scan rate using the redox probe system above to obtain the corresponding peak current. Then is it correct to determine the diffusion coefficient of the redox probe system by presuming the geometry area of the unmodified SPCE as the active area of the SPCE in the Randles-Sevcik equation? Then is it correct for us to calculate the active area of the modified SPCE using the determined diffusion coefficient of the redox probe system?

  • Rajesh NeupaneRajesh Neupane
In particular oversampling is done on train dataset, in order to prevent data leakage in test dataset,
as of Undersampling, I am not clear how to proceed?
Doing Undersampling before train test split has a very good predictive ability of the model, am I good to go with this approach?

Indicator for detecting wastewater spills to surface water?
Question
4 answers
  • Asked 12th Aug, 2022
  • Goran KhalafGoran Khalaf
I'm working with a case where there is high risk of wastewater contamination to a lake that is raw water source for a treatment plant. Close to the raw water intake there are two wastewater pipes (pressurized) lying on on the seabed about 50 m from the raw water intake. We are concerned that a leak in the wastewater pipes will reach the raw water inlet.
What is the best parameter(s) that can be monitored on-line and is a good indicator of wastewater contamination? Will ammonia be a good indicator? It can be measured on-line with an Ion Selective Electrode.
Are there any effect of adding excess amount (about 10%) of nitric acid to preserve water samples before further analysis with AAS or MP-AES?
