Heavy Metals Mobilization And Bioavailability In A Tropical Estuarine Lagoon In South-West Nigeria

ABSTRACT Environmental issues related to heavy metals and their biological effects continously heightens investigation into the risk associated with their presence and accumulation in aquatic ecosystems globally. This study investigated the mobilization, partitioning, bioavailability and risk associated with the heavy metal levels in the Lagos Lagoon between September 2013 and February 2015. It entailed the division of the lagoon into five zones and sampling carried out on a seasonal bas...

Spatial Distribution Of Suspended Particulate Matter (Spm) In Mtwapa Creek And Funzi Bay - Kenya

AbstractSurface water concentrations of inorganic nutrients and suspended particulate matter (SPM) components were examined and compared between Mtwapa and Shirazi creeks in Kenya. This was aimed at assesing the ecological situation of the two creeks and determine the influence of sewage discharge. The results obtained were further compared with those from Ramisi, an estuarine system. Mtwapa recorded higher nutrient, chlorophyll a and phytoplankton carbon concentrations than Shirazi. The two ...

Comparative Study Of Some Aspects Of Biology Of Three Mangrove Crabs From The Mangrove Wetland Of Lagos Lagoon Nigeria

ABSTRACTThe size composition, growth patter and feeding habit of 395 crab specimens of the hairy mangrove crab - S. huzardii, fiddler crab - U. tangeri and land crab - C. armatum collected from the mangrove swamp of the Lagos Lagoon were examined for six months. The carapace length of S. huzardii ranged from 1.70 cm - 4.60 cm (Carapace width from 1.90 cm - 3.60 cm) whilst that of U. tangeri ranged from 1.10 cm - 3.60 cm (Carapace width from 1.40 cm - 4.20 cm) and C.&n...

The Artisanal Fishing Gears, Crafts Technology And Their Efficiency In The Lekki Lagoon, Nigeria

ABSTRACT The water quality characteristics, artisanal fishing gear and crafts technology and the Fish fauna composition in the Lekki lagoon between March, 2006 and February 2008 were investigated. The water quality analysis indicated that salinity Is drastically increased recently in the lagoon (0.007 4.70%). This study identified three possible sources for saline water intrusion, beyond the sun put in the adjacent lagoons (Lagos and Mahin) salt water intrusion by subsurface flow thr...

Phytoplankton Biomass And Diversity At The Iyagbe Lagoon Lagos, Nigeria

ABSTRACTFluctuations in phytoplankton biomass and diversity in relation to environmental factors at the Tyagbe lagoon, Lagos were investigated monthly from October, 2004 to September, 2006. The water quality indices reflected seasonal changes closely related to rainfall distributive patter and tidal seawater incursion. Whereas air temperature, surface water temperature, total dissolved solids, transparency, sulphate, silica, dissolved oxygen, conductivity, salinity, chloride, pH, acidit...

Ecological Study Of The Molluscan Fauna On Intertidal Artificial Rocky Shore Of Tarkwa Bay Area, Lagos, Nigeria

Abstract The molluscan community living in the three moles of Tarkwa Bay, Lagos was studied monthly between April 2008 and March 2010. These moles are made of rock known as the west, training and east. They provide attachment surfaces for the settlement of littoral communities. The study investigated the physico-chemical parameters, nutrients, heavy metals concentration levels in sea surface water, algae and resident molluscs of the three moles. Molluscan diversity, feeding, guts conten...

OIL BUNKERING IN NIGERIA’S NIGER DELTA REGION (1990-2007)

A B S T R A C T   Bunkering has to do with the fueling of Ships. It is a legitimate trade whereby licensed operators are authorized to provide fuel and other provision to vessels.  This study has appraised the practice of the bunker trade in Nigeria with emphasis on the Niger Delta Region and to demystify all that has been stated about illegal bunkering in Nigeria.  Bunkering as an organized trade has traders, brokers and buyers who play very important roles.  These h...

Biomarker Responses Of Estuarine Macroinvertebrates Of Lagos Lagoon Exposed To Drill Cuttings

Abstract The toxicity, accumulation of hydrocarbon and selected heavy metals, and biomarker responses were investigated in three macroinvertebrate species of Lagos lagoon exposed to drill cuttings.

An Ecological Study On The Macrobenthic Invertebrate Community Of Epe Lagoon, Lagos

ABSTRACTAn ecological study of the macrobenthic invertebrates community of Epe Lagoon was carried out.

Information Technology And Sustainable Development In The Maritime Industry In Nigeria (A Case Study Of Nimasa)

ABSTRACT  The Nigerian Maritime Administration and Safety Agency is a maritime regulatory agency and concerns with enormous responsibilities such as promoting indigenous shipping lines, shipping development, pollution control, ensuring adherence with IMO and ILO conventions among others, So based on the above functions, the research work will look into Information Technology as a sustainable index in the maritime industry. The research will first look i...

Evaluation of transport infrastrtural development In nigeria and its effect on the national economy [1981‐ 2004]

ABSTRACT Transport infrastructure is the fixed part of a transport system. Transport infrastructure development remains one of the major tools for achieving the much needed rapid economic growth in Nigeria. Hence, the study aims at investigating the effect of funding on transport infrastructure development and the implication of this to the economy. The scope of the study was confined within the time frame of 1981-2004. The researcher used GDP, Budgetary Allocation to Transport and the Contri...

The Prospects And Challenges of Maintenance in Onne-Port Operations

 ABSTACT This research assesses the challenges and prospects of maintenance in Onne ports operations. Data were obtained from eighty maintenance staff in Federal Ocean Terminal (FOT) and Federal Lighter Terminal (FLT) using questionnaire. Simple random sampling technique was used in selecting the sample used for this research. The Yaro Yamen formula was employed to determine the sample size. Data were converted from ordinal scale to interval scale and three hypotheses were tested w...

Assessment Of Port Performance: The Queuing Theory Approach (A Case Of Apapa Port Complex)

ABSTRACT This research focused on assessing the port performance: the queuing theory approach using Apapa port complex (APC) as the case study. The research was designed and carried out to answer among others the following questions: to assess the level of vessel turnaround time, traffic intensity, the waiting time of calling vessels at the port? Also, to determine the probability of vessel queuing on arrival at the port? To answer these questions only primary means of data collect...

Analysis Of Cargo Pilferage In Nigerian Seaports: Pre And Post Concession Eras

CHAPTER ONE INTRODUCTION 1.0 Background Information The seaports are very important to the Nigerian trade as practically all imports and exports move through the ports. The importance of the seaports is attested to by the fact that approximately 99% by volume of Nigeria total imports and exports are seaborne; Nigeria ports control 60% of import into West and Central Africa. The ports have served as a major determinant of how economic activities are distributed. The volume of...

An Evaluative Study Of Inland Water Transport Development In Nigeria.

ABSTRACT This is an evaluative study of Inland Waterway Transport Development in Nigeria. Three sets of 5 point Likert Scale questionnaire were crafted for the study for the following categories of respondents; National Inland Water Authority (NIWA) Staff, Ferry Operators and the Inhabitants respectively. Five research questions and five hypotheses were also formed for the study. Data collected were analyzed with descriptive and inferential statistics such as mean procedure and On...
