Analysis of heavy metals found in vegetables from some cultivated irrigated gardens in the Kano metropolis, Nigeria

  The use of industrial and domestic wastewaters for irrigation on vegetable gardens is a public health concern. Using atomic absorption spectrophotometry (AAS), concentrations of Cr, Co, Cu, Ni, Pb and Zn were determined in four different vegetables, including,spinach, okra, onions and tomatoes, grown in effluent irrigated fields at Sharada, Kwakwachi and Jakara in the Kano metropolis, Nigeria. Similar...

Heavy metal impact on growth and leaf asymmetry of seagrass, Halophila ovalis

  A major threat to the seagrass ecosystem worldwide, due to the growth of human population along the coastal environment, is pollution or contamination resulting from industrial and urban development. Although seagrass appears to be rather resistant to heavy metal contaminants, these substances may possibly harm some components of the seagrass and such responses have not been examined to a significant...

Evaluation of the levels of organochlorine pesticide residues in water samples of Lagos Lagoon using solid phase extraction method

  Water samples were collected from 6 different locations of the Lagos lagoon at 0.5 and 2.5 m depths, respectively and from 2 other river bodies in Lagos and analyzed for the presence of 9 OCPs (organochlorine pesticides) residues. Samples were extracted using solid phase extraction method and were analyzed with gas chromatography. The analytes quantified included chlordane (0.006 to 0.950 µg/L),...

Acute toxicity and behavioral response of freshwater fish, Mystus vittatus exposed to pulp mill effluent

  The present study deals with the acute toxicity (LC50 evaluation) of paper mill effluent to a freshwater fish, Mystus vittatus. A monthly record covering all the spawning season (pre-spawning phase, spawning phase and post-spawning phase) was evaluated at different exposure periods (24-, 48-, 72- and 96-h) using the whole paper mill effluent. Annual variation in LC50 values in relation to...
