The application of fatty substances to enhance the denitrification efficiency of high salinity wastewater with a high content of nitrates seems like a plausible strategy to resolve the above-mentioned issues.
This can be illustrated by the example of saline wastewaters with a high content of nitrates originating from the production of explosive materials (Glass and Silverstein 1999), chemical fertilizers (Leakowić et al. 2000), regeneration of ion-exchange resins (Cyplik et al. 2010) and others.
Rain near industrial areas commonly contains high contents of sulfate, nitrate, and carbon dioxide (CO2) largely derived from the burning of coal and oil.
Chemical fertilizers, such as potassium chloride, ammonium nitrate and other chemical products like sodium hydroxide and soda ash are produced from electrolyte solutions or brines with a high content of soluble salts.
For this purpose, we analyzed by spectrophotometry the content of nitrate, total amino acids and total insoluble protein in leaves.
The content of nitrates and nitrites in cheese is therefore strictly regulated by law in many European countries.
Future studies will reveal if such life span extension in any way is linked to the high nitrate content of this food group.
Some of the growth enhancement in these mixtures seemed to be related to the combined effects of improved porosity, aeration and water retention in the medium and the high nitrate content of the substrate, which produced an increased uptake of nitrogen by the plant tissues, resulting in increased plant growth.
This result does not support the earlier finding by others that stomach-cancer mortality in the town was significantly raised, nor the accompanying suggestion of an association with the high nitrate content of the local drinking water via the action of nitrosamines.
The plants were supplied with high concentration of nitrate (HN, 0.375 mM of nitrate) and D42 corresponds to pod formation and D70 to the start of seed filling.
