River Ngong, one of the major rivers in the Nairobi river basin receives enormous amounts of solid and liquid waste from industrial and domestic discharges. This exposes the river to high pollution. An environmental concern arises especially on its unknown levels of hazardous persistent organic pollutants in particular the polycyclic aromatic hydrocarbons (PAH). Notably, its untreated water from some sections along its course is used for domestic purposes hence poses human health risks that may be attributed to long term exposure and accumulation of PAH. United States Environmental Protection Agency (US EPA) not only identifies sixteen priority PAHs that are carcinogenic and mutagenic but alongside other world bodies including WHO, have recommendations for their allowable threshold in water. Previous studies on this river have focused on pollutants such as heavy metal.. View More»
