  1. The effect of hydroxide solutions on the structural stability and saturated hydraulic conductivity of four tropical soils

    The effect of hydroxide solutions on the structural stability and saturated hydraulic conductivity of four tropical soils

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Industrial and domestic effluents are widely applied to soil as a way of dumping, and/or source of nutrients and water for plant growth. The potential effects of sodium hydroxide (NaOH) and potassium hydroxide (KOH), which are common hydroxides found in...
  2. FUTURE CHALLENGES IN WATER QUALITY MODELLING WITH PARTICULAR REFERENCE TO OPERATIONALLY CLOSED CATCHMENTS

    FUTURE CHALLENGES IN WATER QUALITY MODELLING WITH PARTICULAR REFERENCE TO OPERATIONALLY CLOSED CATCHMENTS

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    As a result of the declining quality of many water sources, the use of water quality models in planning is increasing. To date applications have involved the simulation of total dissolved salts and nutrients, largely in catchments affected by urban...
  3. THE USE OF TOXICITY TESTING IN EFFLUENT REGULATION AND CONTROL: A NEW DIMENSION TO ASSESSMENT AND MANAGEMENT OF WATER QUALITY IN SOUTH AFRICA

    THE USE OF TOXICITY TESTING IN EFFLUENT REGULATION AND CONTROL: A NEW DIMENSION TO ASSESSMENT AND MANAGEMENT OF WATER QUALITY IN SOUTH AFRICA

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    Efficient management tools are continually required to cope with increasing demands placed on the quality and quantity of aquatic resources. Recent developments in environmental monitoring indicate the importance of incorporating biological indicators in assessment programmes. Aquatic toxicology has consequently become...
  4. Characterisation of potential aquaculture pond effluents, and physico-chemical and microbial assessment of effluent-receiving waters in central Ghana

    Characterisation of potential aquaculture pond effluents, and physico-chemical and microbial assessment of effluent-receiving waters in central Ghana

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    An understanding of specific aquaculture systems and the impacts of their management practices leads to sound and cost-effective policies to protect the aquatic environment. Water samples were collected in 2009 from fish ponds, streams that receive effluents directly from ponds...

    FUTURE CHALLENGES IN WATER QUALITY MODELLING WITH PARTICULAR REFERENCE TO OPERATIONALLY CLOSED CATCHMENTS

    As a result of the declining quality of many water sources, the use of water quality models in planning is increasing. To date applications have involved the simulation of total dissolved salts and nutrients, largely in catchments affected by urban...
  6. The impact of feedlot effluent on water quality and aquatic macroinvertebrate community structure in streams of the upper Vaal River catchment, South Africa

    The impact of feedlot effluent on water quality and aquatic macroinvertebrate community structure in streams of the upper Vaal River catchment, South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The impact of three intensive feedlots on aquatic macroinvertebrate community structure under high and low flows in the upper Vaal catchment was investigated. Water quality variables recorded upstream and downstream of feedlot activity include pH, dissolved oxygen, conductivity, temperature, turbidity,...
  7. Water quality assessment of the Siluko River, southern Nigeria

    Water quality assessment of the Siluko River, southern Nigeria

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The water quality of the Siluko River, Edo State, Nigeria was investigated from March to August 2015 to determine its suitability for drinking and usage for domestic purposes. Water samples collected from three stations were tested for thirteen physico-chemical parameters...
  8. Heavy metal contamination of water and fish in peri-urban dams around Bulawayo, Zimbabwe

    Heavy metal contamination of water and fish in peri-urban dams around Bulawayo, Zimbabwe

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Urban effluents are significant sources of heavy metal pollution in fresh water. Metal contamination in dams around the city of Bulawayo, Zimbabwe, were monitored during October 2014 to assess ecological and public health risks. Heavy metals were measured in water,...
  9. Occurrence of oestrogenic pollutants and widespread feminisation of male tilapia in peri-urban dams in Bulawayo, Zimbabwe

    Occurrence of oestrogenic pollutants and widespread feminisation of male tilapia in peri-urban dams in Bulawayo, Zimbabwe

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Peri-urban water bodies are at risk from excessive pollution as they are direct sinks for urban effluents. The occurrence of oestrogenic and androgenic endocrine disrupting chemicals (EDCs) in effluents and water bodies around the city of Bulawayo, Zimbabwe, and their...
