Hace 3 días · Nitrogen (N) from point or nonpoint sources has been emerging as a predominant contributor causing suboptimal water quality in eutrophic streams and rivers in the United States 1,2 and across the ...
Hace 1 día · I wrote this text as a cause and effect text that would also describe point and nonpoint water pollution. Over the years, I have used it for reading instruction and science lessons in both fourth and sixth grades. It's a workhorse text that provides good background for further investigation.
Hace 1 día · Nitrous oxide (N2O) is a long-lived greenhouse gas that mainly originates from agricultural soils. More and more studies have explored the sources, influencing factors and effective mitigation measures of N2O in recent decades. However, the hierarchy of factors influencing N2O emissions from agricultural soils at the global scale remains unclear. In this study, we carry out correlation and ...
Hace 2 días · Nonpoint source pollution (NPS) is a complex challenge that transcends political boundaries, ecosystems, and industries. Rainwater flowing through city streets carries pollutants into storm drains, resulting in urban runoff that harms urban watersheds.
Hace 4 días · Agricultural non-point source pollution control (ANSPC) is a complex, long-term and dynamic environmental protection process. In order to motivate multiple subjects to participate in ANSPC, this paper constructs a tripartite evolutionary game model of local government, village collectives and farmers, which explores the strategic choices and influencing factors of different subjects through ...
