Project title

Occurrence and Effects of Pharmaceuticals in Rivers

Project overview

Since it is a well-known fact within the environmental scientists community and regulatory agencies that pharmaceuticals are present in micro-concentrations in rivers and even drinking water. A lot of human and financial resources had been invested to find out the environmental effects and risk posed by these emerging contaminants in the aquatic ecosystems but very little is known.  However, there are significant gaps in terms of data on occurrence of pharmaceuticals in African rivers.  Aside lack of occurrence data for some relatively unstudied pharmaceuticals and those routinely present in rivers major ecological effects have been detected for some of these compounds (e.g. synthetics oestrogen effects on fish sexual organs; Sumpter and Johnson, 2008; Hannah, 2009) but most still remain unstudied. Generally, the acute toxicity towards non-target organisms has been assessed in the laboratory experiments, but chronic toxicity studies particularly using environmental relevant concentrations has been rarely performed possibly because of the longer time it takes and the economics of cost involved.

Hughes et al., 2013 reported that pharmaceutical occurrence studies have been conducted in at least 41 countries such as in Austria, Brazil, Canada, Croatia, England, Germany, Greece, Italy, Spain, Switzerland, Netherlands and the U.S.   He also reported that research is extremely limited or absent in most of South America, central and southern Asia and  none in Africa.  This work will be the first to find out the occurrence of pharmaceuticals in African rivers. It will also be the first to investigate the effects of pharmaceuticals on multispecies assemblage (8 different species) in an outdoor mesocosm experiment using environmental relevant concentrations.

Aim:

The broad aim of this research is to quantify the occurrence of selected pharmaceuticals in African Rivers (Nigeria) and to seek to improve the understanding of the effects of prolonged low-level exposure of freshwater ecosystems to pharmaceutical pollution.

Objectives:

  1. To  carry out repeated monthly grab sampling of previously unstudied effluents  and receiving waters downstream of point source over a period of 12  months  in other to allow inter-annual effects.
  2.  To examine seasonal and temporal trends in pharmaceutical concentrations in the selected study site in Lagos, Nigeria.
  3. To  assess the ecological effects of prolonged low-level exposure of  pharmaceuticals on growth, feeding, mortality and metabolic profile of freshwater benthic macro-invertebrate animals using nuclear magnetic resonance environmental metabolomics techniques.
  4. To  determine the differences in effects between different invertebrate species i.e. (Gammarus pulex and Asellus aquaticus)
  5. To examine the effects of pharmaceuticals on multispecies assemblage
  6. To examine the multiple mixture of pharmaceuticals on macro-invertebrates.
