Remediation of the City of Zagreb Jakusevec Dump Site, one of the largest dump sites in Europe, is in progress. Experimental laboratory results of leach­ ate treatment using aquatic macrophytes show that increasing the concentra­ tion of ammonia in the leachate decreases elimination efficiency. In all series of experiments, significantly greater elimination of ammonia and orthophos­ phates has ...

in the present study, cadmium (cd) accumulation capabilities of aquatic macrophytes ceratophyllum demersum, bacopa monnieri and rotala rotundifolia were determined after treating both individual and triple macrophytes. the macrophytes were treated with cd at 0, 0.1, 1 and 10 mg/l concentrations in a controlled chamber for 12-days. cadmium accumulations increased with increasing cd concentration...

Macrophyte communities play an essential role in the way freshwater ecosystems function. It is thus of great concern to understand how environmental factors, especially anthropogenic ones, influence their composition and diversity. The aim of this study was to examine whether the effects of a herbicide mixture (50% atrazine, 35% isoproturon, 15% alachlor) on single macrophyte species can be use...

Cyanobacteria associated with Anopheles albimanus Wiedemann larval habitats from southern Chiapas, Mexico, were isolated and identified from water samples and larval midguts using selective medium BG-11. Larval breeding sites were classified according to their hydrology and dominant vegetation. Cyanobacteria isolated in water samples were recorded and analyzed according to hydrological and vege...

Invasive plant species are among the major threats to freshwater biodiversity. Few experimental studies have investigated whether native plant diversity can provide biotic resistance to invaders in freshwater ecosystems. At small spatial scales, invasion resistance may increase with plant species richness due to a better use of available resources, leaving less available for a potential invader...

Diquat is the only herbicide registered in New Zealand for the control of submerged invasive weeds such as hornwort or coontail ( Ceratophyllum demersum L) . However, under turbid conditions, binding to clay and charged particles in the water may deactivate diquat. To determine whether endothall achieved better control of Coontail under turbid conditions, both diquat and endothall were applied ...

The paper deals with 26 species of plants covering 24 genera and 21 families used by the tribes Adilabad district for cooling. Cucurbitaceae is dominant family 3 followed Sapindaceae, Sapotaceae , Arecaceae (2 spp each) others. Trees are 10 herbs (8 spp) Fruits in a maximum 12 practices leaf (6) Ceratophyllum demersum, 15 were found to be new. KEY WORDS: Ethnomedicine, Cooling, district, Andhra...
