Seasonal dynamics of the inorganic nutrients from aquatic complex Somova-Parcheș in 2016
Journal Title: Scientific Annals of the Danube Delta Institute - Year 2016, Vol 22, Issue
Abstract
The existence of nitrogen compounds influence variety, abundance and nutritional value of aquatic organisms. This study aimes to analyze the dynamic of nutrient inorganic forms in spring (March), summer (July) and autumn (September) seasons, in 2016. The selected sampling points were: Somova- Parcheş complex inlet (S1), Somova-Parches complex outlet channel into the Danube River (S2), rainwater and cooling water discharge from the industrial zone of Tulcea (S3), Casla lake (S4), Somova lake (S5), Parches lake (S6), Rotundu lake (S6). Study results show that the physico-chemical characteristics and surface water quality from the aquatic complex Somova-Parches are determined by natural factors (climate, flowing regime) and also by the effects of industrial activities of Tulcea town. Also, it were identified exceedings of maximum allowed concentrations for good ecological status, established by the Water Framework Directive transposed into Romanian legislation through MMGA Order 161/2006.
