| dc.description.abstract1 | This research investigated the source and fate of di erent chemical species of N and P on
a deep tropical urban reservoir, the artificial Lake Paranoá, located in the city of Brasilia (Brazil).
To determine an N and P budget, nutrient input from the external load (four main tributaries and two
wastewater treatment plants), internal load (from sediment) and nutrient output (from a downstream
dam) were estimated empirically. Nutrient storage was evaluated in two compartments: water
column and sediment. Nutrient input from the tributaries varied by season presenting higher loads
in the wet season, especially N. Nutrient budgets in our study indicated that Lake Paranoá retained
dissolved inorganic nitrogen (DIN), PO4
3-P, total organic phosphorus (TOP) and exported total
organic nitrogen (TON), both on a seasonal and annual scale. Surface sediment is the major storage
compartment for both N and P. These results show the pressing need for action to reduce the P
outcome charges, mainly, from the wastewater treatment plants. The data here presented contributes
to the recognition of this situation and to a better comprehension of these nutrient dynamics, as well as
an understanding of the behavior of tropical deep-water reservoirs. This can help to promote more
e ective management, providing a reference for other similar systems. | pt_BR |
