Assessment of the Physico-Chemical Status of Water Samples from Major Dams in Ekiti State, Nigeria

Determination of physico-chemical parameters and heavy metals in water samples from Itaogbolu area of Ondo-State, Nigeria

“…This could be attributed to geological distribution of minerals that vary from one location to the other. Similar variations were reported in sediment of major dams in Ekiti State (Adefemi et al, 2007).…”

Assessment of Wastewater in Duhok Valley, Kurdistan Region/Iraq

“…Table 4 shows a variation pH values among the studied valley waste water. the minimum value of (5.7) was recorded in site Azady bridge in March, while the maximum value of (8.2) recorded in site Bakhotme in March , this increase of pH due to nature of pollutions which reach to the Duhok valley, such as fertilizers and detergents that has alkaline effect on the water [9][10]. Dissolved oxygen is an important parameter for water quality as well as the importance of living of aquaculture operation, and self-purification ability of water and prevents the formation and emission of unfavorable odors and harmful compounds for the environment.…”

Assessment of Heavy Metals Associated with Bottom Sediment of Asejire Reservoir, Southwest Nigeria

“…Concentration of Fe, Cu and Pb are uniformly higher than the background value. The high value of Fe in the reservoir is not unusual, as this phenomenon has been reported to be dominant in most tropical aquatic ecosystem [32,13,14,33,9]. Lead is toxic to humans and is a major anthropogenic sources included in the use of lead as petrol additives, runoff from cities, discharge on improperly treated waste effluents, sewage sludge and the use of pesticides containing lead compounds.…”
