Contaminación por nitrógeno inorgánico en los ecosistemas acuáticos: problemas medioambientales, criterios de calidad del agua, e implicaciones del cambio climático

摘要: Inorganic nitrogen pollution in aquatic ecosystems: environmental problems, water quality criteria, and implications of climate change. The major problems related to inorganic ecosystems are: (1) acidification lakes rivers with low or reduced alkalinity; (2) eutrophication fresh marine waters (with the additional problem toxic algae); (3) direct toxicity nitrogenous compounds animals. Additionally, could induce adverse effects on human health. On basis different we consider that maximum levels dissolved within range 0.5-1.0 mg DIN/l (or even better total TN/l) may be suitable prevent processes (at least by nitrogen) and, at same time, protect animals (and also humans) against NH3+, NH4+, HNO2+, NO2-, NO3-. This concentrations would not applicable those naturally high levels. We conclude commented can becomeacute world’s regions (for example, southern Spain) where reductions resources rises temperatures are expected occur as a consequence current
