Assessment of heavy metals concentrations in coastal sediments in north-western cities of Madagascar

  This study was undertaken to evaluate the heavy metals contamination of copper, zinc, manganese, iron, chromium, nickel, lead and cadmium, to assess the environment quality of the coastal area from town activities. Nickel, lead and cadmium are used in different kind of current accumulators and they are dangerous for sea wild life and for human food resources. The five others metals are usual and at a high...

Seasonal variations in water quality and major threats to Ramsagar reservoir, India

Ramsagar reservoir, a small inland reservoir located in Datia district, Madhya Pradesh is constructed over Nichroli nallah, in the basin of Sindh River. The physico-chemical characteristics, trophic status and pollution studies of Ramsagar reservoir have been studied from April, 2003 to March, 2005. The nutrients including silicates (0.65 - 8.42 mgl-1), sulphates (1.50 - 8.87 mgl-1), phosphates (0.013 - 0.054 mgl-1),...

Comparative assessment of heavy metal removal by immobilized and dead bacterial cells: A biosorption approach

  Microorganisms play a vital role in heavy metal contaminated soil and wastewater by the mechanisms of biosorption. In this study, heavy metal resistant bacteria were isolated from an electroplating industrial effluent samples that uses copper, cadmium and lead for plating. These isolates were characterized to evaluate their applicability for heavy metal removal from industrial wastewaters. The...

The effects of incubation period and temperature on the Hydrogen sulphide (H2S) technique for detection of faecal contamination in water

  A total of 171 water samples from 3 sources were analyzed for the presence of faecal contamination by standard MPN, P/A, EC-M and H2S techniques at different temperatures and incubation times. Analysis of water samples by H2S technique showed that the incubation period of H2S bottles is highly dependent on temperature and concentration of faecal coliform bacteria. Incubation temperature was changed from 22 to...

Analysis of some meteorological data for some selected cities in the Eastern and Southern zone of Nigeria

  The monthly mean daily global solar radiation, sunshine duration hours, maximum temperature, Cloudiness index and relative humidity data for some selected cities in the Eastern and Southern zone of Nigeria covering a period of seventeen years (1990 - 2007) were used to generate several linear and multilinear regression equations. The values of the solar radiation estimated by the equations and the measured...

Comparative effects of undigested and anaerobically digested poultry manure on the growth and yield of maize (Zea mays, L)

  A comparative study of the effects of undigested and anaerobically digested poultry manure and conventional inorganic fertilizer on the growth characteristics and yield of maize was investigated at Ibadan, Nigeria. The pot experiment consisted of sixty (60) nursery bags, set out in the greenhouse. The treatments, thoroughly mixed with soil, were: control (untreated soil), inorganic fertilizer, (NPK 20:10:10)...
