Heavy metals pollution profiles in streams serving the Owabi reservoir
Water samples from five sampling points on four rivers, Owabi, Akyeampomene, Pumpunase and Sukobri, representing the main streams serving the Owabi reservoir were analysed for some pollution indicators using standard methods. Heavy metals (Zn, Cu, Mn, Cu, Pb and As) concentrations and some physical parameters of the water samples were determined. Electrical conductivity and pH of...

Metal tolerant species distribution and richness in and around the metal based industries: Possible candidates for phytoremediation
Plant species growing in and around 38 metal welding workshops in Benin City, Nigeria, were surveyed. Eragrostis tenella occurred most frequently in all the sites, followed by Amaranthus spinosus, Eleusine indica, while Cucurbita pepooccurred least. The family Poaceae, was identified in all the sites visited. The frequency of occurrence of any particular plant species was used as an...

Parasitism of host trees by the Loranthaceae in the region of Douala (Cameroon)
The Loranthaceae constitute the most important parasite plants that cause variable damages: morphological, technological, ecological and socio-economic. These numerous and damaging effects make some parasitic angiosperms true agronomic threats, especially in developing countries. The Loranthaceae is represented in Cameroon by 26 species gathered into 7 genus. The study area includes four...

Water supply, sanitation and health risks in Yaounde, Cameroon
Population growth and rapid urbanization in Cameroon have led to major demographic changes in the urban centres, potentially resulting in serious environmental problems in the most populated cities such as Yaounde. In order to better understand the impacts on the hygiene conditions in certain quarters of this political capital, we carried out in March 2007, an investigation on the difficulties of water...

Mineralogical and geochemical study of mud volcanoes in north Moroccan atlantic margin
The gulf of Cadiz is one of the most interesting areas to study mud volcanoes and structures related to cold fluid seeps since their discovery in 1999. In this study, we present results from gravity cores collected from Ginsburg and Meknes mud volcanoes and from circular structure located in the gulf of Cadiz (North Atlantic Moroccan margin) during the cruise TTR14 in 2004 on board of the R/V Logachev. The...

Distribution of nitrate in the water resources of Pakistan
Water quality monitoring activities have recognized the nitrate contamination in the drinking water sources as one of the major quality issue of Pakistan. Adopting a uniform sampling design, 747 samples were collected from a wide range of irrigated or non-irrigated regions having distribution of samples in sixteen cities as Lahore (79), Kasur (46), Faisalabad (30), Khushab (50), Chakwal (51), Mianwali (30),...

Comparison of parasitic helminth infection between the different age groups of Clarias gariepinus from Asa dam Ilorin, north-central Nigeria
A total of 160 specimens of Clarias gariepinus comprising three age groups – juveniles (standard length 10.0 – 29.9 cm), sub-adults (fish length 30.0 – 39.9 cm) and adults (fish length 40.0 – 59.9 cm) were collected over a period of 8 months from Asa dam, a major river in Ilorin. The fish length and weight ranged from 12.5 to 41.0 cm and 152 to 597 g respectively. They were...
