Abstract
The nutrients (nitrate, nitrite, phosphate and silicate) of thirty-two study stations in the Ilaje, coastal waters and Estuaries of Ondo State, Nigeria were studied in the month of August (during the wet season).
Highlights
Tropical estuaries are highly productive due to the essential features of mangroves, which in turn modify the biogeochemistry, nutrients distributions and characteristics of the phytoplankton biomass of the coastal systems (Alongi, 2001; Burford et al, 2008).Oceans are ecosystems that are quite vulnerable to pollution; they are made up of continental shelf and deep sea
The aim of this research is to: (i) evaluate the nutrient status in Ondo coastal waters in response to the stress caused by anthropogenic inputs from land use changes, agriculture, and industries. (ii) Determine eutrophication status of the study area using chlorophyll-a scaling proposed by Karydis (1999) and modified by Pavlidou et al, (2005) as an indicator
The aim of this research is to evaluate the nutrient status in response to the stress caused by anthropogenic inputs from land use changes, agriculture, and industries, and eutrophication status of the Ilaje coastal waters, and Estuaries, Southwest Nigeria, using chlorophyll-a as an indicator
Summary
Tropical estuaries are highly productive due to the essential features of mangroves, which in turn modify the biogeochemistry, nutrients distributions and characteristics of the phytoplankton biomass of the coastal systems (Alongi, 2001; Burford et al, 2008).Oceans are ecosystems that are quite vulnerable to pollution; they are made up of continental shelf and deep sea. Tropical estuaries are highly productive due to the essential features of mangroves, which in turn modify the biogeochemistry, nutrients distributions and characteristics of the phytoplankton biomass of the coastal systems (Alongi, 2001; Burford et al, 2008). Coastal waters serve as interface between terrestrial environments and the open ocean. They are one of the nation’s most imperative natural resources, esteemed for their ecological richness as well as for the many human activities they support (Ajibare, 2014). The continental shelf and Estuaries are continuously under the threat of pollution by biological, physical and chemical contaminants that emanate mainly from weathering, hydrological features, precipitation, climate change, erosion, industrial activities, sewage discharge, agricultural land use, and the human exploitation
