A Point of View about Ecological Status of Maritime Lakes
Journal Title: HIDRAULICA - Year 2018, Vol 0, Issue 2
Abstract
The lake Techirghiol comprises three distinct areas from a topographical, physical-chemical and biological point of view (hypersaline area of spa interest, majority as surface, intermediate area –buffer-, freshwater area) separated between them through protective dikes. Research: the period of observation was chosen May–June at the limit of the two seasons, spring and summer. Physical-chemical and electrochemical analyses were performed on water and sediment samples. Results: during the period of observations the three areas manifested differently. In the first two, the values of salinity were not altered, and in the hypersaline area they decreased by 20–25%. The hydro chemical analyses included the evaluation of dissolved O2 content and biogenic substances. The dynamics of these parameters evolved differently. Balanced distribution was the result of normal biological activities; excessive accumulations were due to internal ecological de-adjustments or some external contributions to the system.
