In fact, due to long-term impacts on food webs, Nr inputs are widely considered the most critical pollution problem in marine systems. [8] In both terrestrial and aquatic ecosystems, responses to N enrichment vary; however, a general re-occurring theme is the importance of thresholds (e.g., nitrogen saturation ) in system nutrient retention ...
Country Location Date Deaths AN (tonnes) Notes United States Gibbstown, New Jersey : 14 January 1916: 1 1.81 In an evaporating pan of the Repauno works, du Pont Co., 1,800 kilograms (4,000 lb) of ammonium nitrate exploded, possibly caused by a clogged air lance leading to overheating of the nitrate. 1 man was killed and 12 were injured.
However, the excessive or inefficient use of nitrogen fertilizers can lead to environmental problems such as nitrogen leaching, runoff, and emissions of nitrogen oxides (NOx). [4] Nitrogen leaching occurs when nitrogen compounds, primarily nitrates , move through the soil profile and enter groundwater, potentially contaminating drinking water ...

An investigation conducted by the United States Environmental Protection Agency (EPA) concluded in 1996 that the explosion was initiated by an accelerated thermal decomposition reaction as "a direct result of unsafe operating procedures and conditions" at the plant.
Earthquake environmental effects are divided into two main types: Coseismic surface faulting induced by the 1915 Fucino, Central Italy, earthquake. Primary effects: which are the surface expression of the seismogenic source (e.g., surface faulting), normally observed for crustal earthquakes above a given magnitude threshold (typically M w =5.5 ...
At the time of the earthquake, Reactor 4 had been de-fueled while 5 and 6 were in cold shutdown for planned maintenance. [4] Unit 1 was immediately shut down automatically after the earthquake, and emergency generators came online to control electronics and coolant systems.
Effects of global warming include loss of biodiversity, stresses to existing food-producing systems, increased spread of known infectious diseases such as malaria, and rapid mutation of microorganisms. This would further amplify human migration, human conflicts such as cross border immigration disputes, leading to increased human conflicts such ...
