2 kwi 2013 · The aim of this present study is to identify the possible sources of nitrate contaminants in Taihu Lake and major inflow rivers as well as assess N transformation process by using the stable N and O isotopic compositions.
1 sty 2020 · The nutrients enter into the lake water through disposal of human excreta and agricultural wastes which are rich in fertilizers containing nitrogen, phosphorous and potassium with phosphorous being the major factor limiting the growth of algae and eutrophication in lake water [15].
A high level of nitrate makes water unsuitable as drinking water. In rivers, lakes and marine waters, nitrogen and other nutrients, in particular phosphorus, stimulate the growth of algae. At moderate levels, algae serve as food for aquatic organisms, including fish.
24 mar 2016 · Water quality can be assessed by various parameters such as BOD, temperature, electrical conductivity, nitrate, phosphorus, potassium, dissolved oxygen, etc. Heavy metals such as Pb, Cr, Fe, Hg, etc. are of special concern because they produce water or chronic poisoning in aquatic animals.
10 mar 2021 · The historic dataset of the eutrophic lake revealed a close linkage between annual loads of dissolved N (DN) and removal rates (NRR = 0.63 × DN load) and a significant correlation of the concentration of bottom water nitrate and removal rates.
26 lip 2012 · Adirondack lake N concentrations reflect the variable processing and loading of nitrogen from watersheds (“indirect inputs”), as well as direct deposition of N from the atmosphere (“direct inputs”) to the lake surface, plus within-lake processing and losses.
19 lut 2020 · Abstract. Eutrophication mitigation is an ongoing priority for aquatic ecosystems. However, the current eutrophication control strategies (phosphorus (P) and/or nitrogen (N)) are guided mainly by nutrient addition experiments in small waters without encompassing all in-lake biogeochemical processes that are associated largely with lake ...
