3. Nitrate in the Mississippi River Basin - Wikipedia

   en.wikipedia.org/wiki/Nitrate_in_the_Mississippi...

   The increase in pollution of the Mississippi River has greatly affected the species that live in the water, as well as those who rely on the river for food and recreational purposes. One of the main types of pollution is an excess of nitrate (NO − 3) caused by chemical wastes from power plants and agricultural runoffs. The watershed covers ...

4. Eutrophication - Wikipedia

   Examples of anthropogenic sources of nitrogen-rich pollution to coastal waters include sea cage fish farming and discharges of ammonia from the production of coke from coal. [55] In addition to runoff from land, wastes from fish farming and industrial ammonia discharges, atmospheric fixed nitrogen can be an important nutrient source in the open ...

   Women who consume water with nitrates over 5 mg/L are at a higher risk of developing thyroid cancer. [25] This 5 mg/L level is 5 mg below the federally accepted limit. When consumed, nitrate can compete with iodine in the body to be taken up by the thyroid. When the thyroid intakes nitrogen instead of iodine, its function may be impaired. [26]

9. Nitrate vulnerable zone - Wikipedia

   en.wikipedia.org/wiki/Nitrate_vulnerable_zone

   Sources of nitrate pollution [ edit ] One of the primary causes of nitrate pollution is the use of nitrogen fertilizers and application of manure to agricultural fields, which stimulates crop production but also contributes to nutrient pollution due to nitrate leaches from soil during heavy precipitation events.
