Fluctuations in Nitrate Concentrations Utilized as an Assessment of Agricultural Contamination to an Aquifer of a Semiarid Climatic Region.

摘要

Aquifer water has become contaminated in arid and semiarid regions that have been developed for agriculture. Nitrate contamination has been shown to be permeable to the aquifer and harmful to human health. Nitrate concentrations have been used in the study to demonstrate their applicability to examining agriculture practices which contaminate aquifer water. Areas treated with nitrogenous fertilizers and subsequently irrigated were found to contain aquifer fluctuations in nitrate content directly in proportion to irrigation seasons. Agricultural industries with high animal densities per land area,and high water consumption for maintenance,were found to have high,but non-fluctuating,nitrate concentrations. (Author)
