Unsuitability for industrial waste: The BOD test might not be essentially the most correct system for evaluating the pollution levels of industrial squander, as it might consist of complicated and varied substances which will interfere with precise BOD measurements.
Mycotoxicity will not be well here outlined. Exploration on mycotoxin testing remains in its infancy. Because of this even people that study mycotoxins or mold for your residing don’t know exactly tips on how to interpret mycotoxin test effects.
The oxygen information is calculated again and BOD is calculated. A higher BOD signifies the presence of numerous microorganisms which implies a superior volume of air pollution in wastewater.
