The Effects Of Groundwater Pollution On The World

Groundwater pollution is a prominent problem in most areas of the world. High nitrate concentrations have been identified as one of the main culprits of groundwater pollution. Agriculture is a primary anthropogenic source involved in the spreading and distribution of nitrates in rural areas. China is considered one of the largest in terms of agricultural production. As the population of China increased over time, the recycling of plant nutrients could no longer renew the loss of nutrients from harvesting. The famine between 1960 and 1970 caused radical changes when it came to policies about population control and large efforts were made to increase agricultural yields. This was encouraged by increasing the application rate of chemical fertilizers, especially ones that were nitrogen based (Emteryd, Lu and Nykyist, 1998). However, higher irrigation and nitrogen fertilizer inputs results in decreased water and nitrogen use efficiency (Hu, Li, and Chen, 2010). Currently China is the lea ding producer of rice, wheat onion cabbage and the second largest producer of corn (See Appendix). Presently the average annual nitrogen fertilizer application is 200 kg N/ha in China (Zhang, Xu, XIaomin, Dong and Ballantine, 2013). As a result of this, China unsurprisingly suffers from large amounts of nitrate pollution in its groundwater, especially in northern China. The main focus of this paper will therefore be on the North China Plain and the provinces surrounding the Yangtze River asShow MoreRelatedSimulation Of Modeling And Distributed Simulation1392 Words   |  6 PagesSimulation on monitoring Environmental Pollution - Harini Ramasahayam Introduction Environment is the surrounding or the biosphere of the earth that consists of air, water and land in which humans, plants and animals live.
