Accumulation of Heavy Metals by Some Aquatic Macrophytes in Two Streams along the Tiko-Douala Highway, Cameroon

Aims: This study was aimed at determining the ecological health of two roadside streams across Tiko-Douala highway, Cameroon, and investigating phytoremediation potentials dominant aquatic macrophytes within these streams.
 Study Design: Water, sediments, plant samples were collected from Camp 7 Moqouo streams, analyzed for ammonium nitrogen, nitrate phosphates, magnesium, cadmium, lead, including other relevant water quality parameters.
 Place Duration Study: In Life Science Laboratory University Buea, Soil Water Dschang, Cameroon between June 2021 2022.
 Methodology: Six six sediment per stream, most species (Pennisetum purpureum Schumach (Poaceae) Dicanthelium clandestinum L. 7, Commelina benghalensis (Commelinaceae) Oldenlandia corymbosa L.(Rubiaceae) stream) heavy metal analysis. Heavy concentration bioaccumulation factors determined each plant.
 
 Results: High concentrations phosphates recorded in (1.19 mg/L) (2.17 streams. Dissolved oxygen levels 0.69 mg/L 0.80 respectively. Sediment cadmium ranged 0.33± 0.02 to 0.63± 0.16 mg/kg, lead 0.34 ±0.03 0.37 ± 0.12 mg/kg Conclusion: The Mouqouo are rich thus not suitable drinking irrigation. Cadmium stream permissible limits but sediments contained higher than therefore they could be released gradually into column. All plants except (Dicanthelium cladestinum) accumulated potential metals.
