摘要: ABSTRACTSurface and groundwater from Pangani River Basin (PRB) were sampled in dry wet seasons, analysed for dissolved organic inorganic nutrients (N, P, Si Urea). There was spatial seasonal nutrients’ variability, with enrichment of fractions accumulated natural anthropogenic sources. Silicates increased season, whereas nitrate, ammonium, phosphate urea season; except phosphate, other upstream to the river mouth. High rate chemical weathering possibly due tropical climate volcanic rocks has caused PRB have higher concentration silicates than average freshwater African Rivers. Contribution coast Indian Ocean 2.6, 39.0, 45.2, 67.4 5444.8 (mol/km2/yr) nitrite, nitrate silicates, respectively, which lower most rivers world. Levels stations recommende...
