Their potential carcinogenicity and toxicity have been proven, particularly after the reduction of nitrate to nitrite itself or just serving as a reactant with amines and/or amides in the formation...

The issue of nitrate contamination has become increasingly acute, with the awareness their toxicity on human body and identification increasing sources contamination. Human intervention in natural nitrogen cycle serious repercussions that are manifested by its accumulation at one or more levels. use fertilizers agriculture is crucial to ensure food security, but unreasonable causes accumulation...
