Effects of water level fluctuation on reproduction and spawning habits of fish species in lake Balaton
Environmental Engineering and Management Journal › Vol. 6 › Nr. 5 AbstractIn 2004, the types of shoreline were estimated on Lake Balaton, such as rip-rap covered, reedy, concrete or grit. Exact area of a specific face of a rock in the rip-rap covered parts can be determined by digital image analysis. Wetted rocky area of the shore was estimated as a function of water level in 10 cm steps of level changes. Taking into account the reproduction characteristics of the studied fish species (Cyprinidae) the potential substrates for spawning are dominantly the shallo...

Treated wastewater reuse represents a sustainable approach to... Autori: Alessandra Bonoli ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28288
FIELD APPLICATION OF A REAGENT FOR IN SITU CHEMICAL REDUCTION AND ENHANCED REDUCTIVE DICHLORINATION TREATMENT OF AN AQUIFER CONTAMINATED WITH TETRACHLOROETHYLENE (PCE), TRICHLOROETHYLENE, 1,1-DICHLOROETHYLENE, DICHLOROPROPANE AND 1,1,2,2-TETRACHLOROETHANE
Environmental Engineering and Management Journal › Vol. 19 › Nr. 10 Groundwater at an abandoned industrial area near Bergamo, Italy, was historically contaminated by tetrachloroethylene (PCE) (>100 μg/L) and, to a lesser extent, by trichlorethylene (TCE), dichloropropane (DP) and 1,1,2,2-tetrachloroethane (R-130). A
liquid reagent (EHC® Liquid) was selected for remediation of groundwater at the site. The reagent is provided in two parts: EHC® Liquid Mix (a soluble organo-iron salt), and ELS® Microemulsion (a lecithin-based carbon substrate), a...
