A conceptual model for the development and management of the Cape Flats aquifer, South Africa
(Water Research Commission, 2010)This paper provides an integrated approach to the analysis of the geological, hydrological and hydrogeological characteristics of the Cape Flats: a coastal plain sand formed within the mountains of the Cape Town metropolitan ... -
Degradation of hydrocarbons and heavy metal reduction by marine bacteria in highly contaminated sediments
(MDPI, 2020)Investigations on the ability of bacteria to enhance removal of hydrocarbons and reduce heavy metal toxicity in sediments are necessary to design more effective bioremediation strategies. In this study, five bacterial ... -
Editor’s message: Building capacity and partnerships towards sustainable utilization of groundwater in Africa
(Springer, 2008)This Editor’s Message advises the international groundwater fraternity of new opportunities in hydrogeological developments in Africa. It is a fact that groundwater plays a vital role in socio-economic and ecological ... -
Effects of film thickness of ald-deposited al2o3, zro2 and hfo2 nano-layers on the corrosion resistance of ti(n,o)-coated stainless steel
(MDPI, 2023)The goal of this stydy was to explore the potential of the enhanced corrosion resistance of Ti(N,O) cathodic arc evaporation-coated 304L stainless steel using oxide nano-layers deposited by atomic layer deposition (ALD). ... -
Happy Feet in a Hostile World? The Future of Penguins Depends on Proactive Management of Current and Expected Threats
(2019)Penguins face a wide range of threats. Most observed population changes have been negative and have happened over the last 60 years. Today, populations of 11 penguin species are decreasing. Here we present a review that ... -
Impacts of plastic debris on biota and implications for human health: A South African perspective
(South African Assn. For The Advancement Of Science, 2020)Entanglement and ingestion of plastics are the main ecological impacts of marine plastic debris on marine biota, but indirect effects such as the transport of alien species and benthic smothering are also important to note. ... -
Near real time water quality monitoring of Chivero and Manyame lakes of Zimbabwe
(Copernicus Publications, 2018)Zimbabwe’s water resources are under pressure from both point and non-point sources of pollution hence the need for regular and synoptic assessment. In-situ and laboratory based methods of water quality monitoring are ... -
Plastic ingestion by estuarine mullet Mugil cephalus (Mugilidae) in an urban harbour, KwaZulu-Natal, South Africa
(National Inquiry Services Centre (NISC), 2016)Coastal urban environments have high plastic pollution levels, and hence interactions between plastic debris and marine life are frequent. We report on plastic ingestion by mullet Mugil cephalus in Durban Harbour, ... -
Reviewing evidence of marine ecosystem change off South Africa
(National Inquiry Services Centre, 2013)Recent changes have been observed in South African marine ecosystems. The main pressures on these ecosystems are fishing, climate change, pollution, ocean acidification and mining. The best long-term datasets are for trends ... -
Synthesis of hydroxy sodalite from coal fly ash for biodiesel production from waste-derived maggot oil
(MDPI, 2019)Zeolites are aluminosilicate crystalline materials known for their unique characteristics, and have been prominent for nearly half a century due to their wide and important industrial applications. The production of zeolites, ...
