Distribution features and polluting source analysis of nitrate in shallow groundwater in the Huaibei plain,Anhui
摘要
Abstract
Nitrate pollution in groundwater is an issue of common concern in many countries and regions in the world nowadays. It is of great importance to study the distribution features of the pollution. This paper,based on hydrogeolog-ical survey and sample analysis,studied the distribution and polluting source of nitrate in shallow groundwater in the Huaibei plain in Anhui Province,indicating that the content of nitrate is higher in the northeastern part of the area stud-ied,even higher than the standard (88mg/L ) for drinkable water in a certain range of area,with the maximum being 432.56mg/L,and lower in the southern. The increase of NO3- keeping pace with Cl- suggests that the major polluting source is living sewage,human and animal excrements,probably joined by farmland fertilizer and irrigating sewage. R factor analysis indicates that the shallow groundwater quality is largely affected by the operation of the nature,mixed action by human and nature,and human action,which contribute 39%,28% and 15% respectively,and nitrate pollution has the highest correlation with human action. So a suggestion is to strengthen control of nitrate nitrogen pollution from human activities in the area studied.关键词
