The true measure of nitrate (ionic) is a multiple of 4.4 times whatever you get on most test kits. So a reading of 10ppm nitrate as nitrogen is actually 44 ppm!!! So for you to be under 10ppm actual nitrogen in the display, you need a test kit reading of 2ppm or lower (tough ...

Globally, consumption of nitrate (NO3−) and fluoride (F−) contaminated groundwater is a serious concern due to their role in causing clinical diseases in humans1,2,3,4,5. Among the different inorganic forms of nitrogen (NO3−, NO2− and NH4+) that exist in aquifers, NO3− con...
In a specific instance, industrial operations and vehicles release harmful substances such as sulfur dioxide and nitrogen oxides—which, in turn, produce acid rain. This, in effect, affects the overall pH levels of nearby water sources. Another factor is chemical pollution which can po...
We talk about plants needing nitrogen, but plants can’t actually use nitrogen. Instead, they absorb nitrate ions (NO3) which contain nitrogen and oxygen. Once inside the plant, they separate the nitrogen from the oxygen and use it. The same goes for sulfur which is absorbed as a sulfate ...

Planting non-point source pollution in China is severe, according to the calculation of equal-standard discharges for ammonia nitrogen (NH3-N), total nitrogen (TN), total phosphorus (TP), and chemical oxygen demand (COD) discharged via fertilizer and farmland solid waste. Based on the 2019 ...
