Lead poisoning of waterfowl from direct ingestion of wetland mine tailings has been reported at the Coeur d'Alene River basin in Idaho. A greenhouse study was conducted to evaluate the effects of surface applications of amendments on lead bioavailability in the tailings. Treatments included sediment only, and sediment with three different surface amendments: (i) biosolids compost plus wood ash,...

Nutrients in breeding sites are critical for the survival and development of malaria mosquitoes, having a direct impact on vectorial capacity. Yet, there is a limited understanding about the natural larval diet and its impact on the individual fitness of mosquitoes. Recent studies have shown that gravid Anopheles arabiensis Patton (Diptera: Culicidae) are attracted by and oviposit in grass-asso...

Typha latifolia (cattail) forms natural stands in the transition zone of artificial flotation and mine tailings ponds is contaminated with extremely high concentrations metals. We assessed absorption capacity plant, metal transfer to leaves, effects elevatedmetal on antioxidant enzyme activities. Soil acidity, pseudo-total available content substrate, plants were examined. The elevated activiti...

Abstract This study investigated, using the closed chamber method, impact of (1) vegetation community type (Typha latifolia, Cyperus papyrus and Phragmites mauritianus) in a natural tropical freshwater marsh wetland (marsh) (2) conversion into rice paddy (rice paddy), on nitrous oxide (N2O) emission. Both were continuously flooded, while was unfertilized. Average N2O emission from did not vary ...

The higher aquatic plant cattails has a wide distribution area, grows almost all over the world and number of unique properties. One these properties is sorption perianth fuzz cattail cobs. high capacity cobs difficult to explain from standpoint small specific surface area this material. data obtained by authors а presented on characteristics Typha latifolia as sorbent oil products. VOPR reache...
