Aquatic plants are always exposed to various types of stresses and the marine\nalgae have been considered as useful bioindicators for detecting different\nkinds of environmental alterations. Present investigation was carried out to\ntest the comparative response of red algae (Gracilaria salicornia and Digenea\nsimplex ) and green algae (Enteromorpha compressa and Sargassum muticum)\nto the contaminants present in their surrounding growth medium. The\nresults of the study show that the studied macroalgae responded differently in\nterms of physiological and biochemical parameters....
The concentrations of As, Cd, Cr, Cu, Ni, Pb, Fe and Zn in selected dumpsites\nin Potiskum were determined with Buck Scientific 210VGB Atomic Absorption\nSpectrometer (AAS) AVG 210............................
Solid waste management is no longer a non-priority issue anymore as improper\nwaste disposal will lead to public and environmental health crisis as well as\neconomic loss. Many nations that are developed have achieved considerable\nsuccess in management of solid waste but the case is different for the developing\ncountries as they are still grappling with issue of waste. Hence in order\nto bridge this gap this study calls for prioritizing and adoption of the right attitude\ntowards proper solid waste management for the Nairobi City County.\nThe study was conducted in order to assess residentsâ?? knowledge and attitude\non solid waste management in Eastleigh South Ward, Kamukunji Sub-county\nin Nairobi City County, Kenya....
Soils and other solid wastes from industrial areas of Nasirabad, Chattogram\nare usually dumped or used for land development. Information about the radioactivity\nlevel presented on these soil and wastes enables one to assess any\npossible radiological hazard to humankind by the use of such materials. A total\nof 37 (31 soils and 6 solid waste) samples near from different types of industries\nalong four kilometre range were collected. The presence and activity\nconcentrations of naturally occurred radioactive materials (NORM) and\nanthropogenic radionuclides in the samples were estimated using HPGe detector\nof 40% relative efficiency....
Globally, air pollution is a significant cause of death, illness and social discomfort.\nThe problem is particularly severe in Nigeria, the country with the\nhighest number of premature deaths due to ambient particulate matter pollution\nin Sub Saharan Africa. It is especially worrying in Lagos, the countryâ??s\ncommercial capital and one of the worldâ??s fastest growing megacities. Despite\ngrowing concerns about its deadly impacts, there is currently no reliable\nmonetary estimate of the effects of ambient air pollution, nor a comprehensive\ncontrol plan in Lagos....
