- The major source of Nitrogen oxides (NOx) pollution is fossil fuel combustion in power station, industrial boilers and motor vehicle engines. During combustion, N2 in the air and nitrogen in the fuel are oxidized to NO. Nearly half of all anthropogenic NOx emissions come from mobile sources, the remainder coming from power stations and industrial boilers. Natural sources of NOx include volcanoes, bacterial activity forest fires and lightning. In the atmosphere, NO is rapidly oxidized to NO2 by ozone.
NO2 is considerably more toxic than NO, and most of the health concerns have been focused on NO2. NO2 can alter lung function and increase susceptibility to respiratory infections. Asthmatics, young children and individuals suffering from chronic respiratory disease may be particularly sensitive to NOx pollution. NO2 contributes to acid rain as it is easily converted to nitric acid (HNO3) in the atmosphere. Sodium Arsenite method are based on bubbling air into a solution followed by colorimetric analysis.
it was one of the nice video in Env sc
Dear sir,
Kindly make one video on sox and nox absorbing media preparation
Very good. Tks
Kindly make one video on calibration curve for both analysis procedure because without this all tesing is incomplete and also tell how to prepare calibration standards for the same.
Can you explain the how to custruct calibration curve for NO2
What is the name of this method
Sir spectrophotometer kis company ka budget mai aa jayega
Respected sir
Sir how to prepare NEDA SOLUTION. 🙏🙏
Blank is distilled water Or initial sampla
Stack me btao sir sample collection
Which method is used in
3:05
What is the initial time ___ reading ?
Hey,
If you please mentioned the method name that is being used in this video
Jacob and hochheiser method
Sir please PM 2.5 video
Me trying to my best to understand what there is to understand in this video: 😵🥴
