Threats
Metal contamination
Like all the rivers in the city, the Mbezi River has faced environmental degradation over decades. Geo-accumulation index, contamination factor, degree of contamination, modified degree of contamination, potential contamination index, and environmental toxicity quotient have all indicated that sediments from Dar's rivers are polluted, with Msimbazi and Kizinga river sediments being more polluted. This is true even though enrichment factor indicates varying contamination status of heavy metals in rivers.
Metal contamination levels for Cd, Pb, Cr, Ni, Cu, Al, Mn, Fe, and Zn were assessed using sediments from the Kizinga, Mbezi, Msimbazi, and Mzinga coastal rivers. Most of the higher concentrations of Cd, Pb, Cr, Al, Mn, Fe, and Zn were found in the Msimbazi River. While higher Ni and Cu concentrations were found in the Kizinga River, higher Mn concentrations were found in the Mbezi River. Except for Mn, Mzinga River has the lowest amounts of most metals. Mn concentrations were lowest in the Kizinga River.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Mbezi River”, the useful work is to connect “river in Dar es Salaam Region, Tanzania” to the records capable of establishing context and consequence.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Dec 21, 2024. The linked authority identifier is Q121590710. Authority coordinates are -6.808, 39.082. None of the 1 selected statements returned an explicit reference.

Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
