Comparative Study on the Influence of Grilling Height on the Concentration of Polycyclic Aromatic Hydrocarbons (PAHS) and Some Toxic Metals in Grilled Foods

Abstract:A comparative study was carried out on the effect of grilling height on the extent of accumulation of the 16 US EPA priority PAHs and some volatile (As and Hg) and non-volatile (Mn, Cu, Pb, Cr, Cd and Ni) heavy metals in two kinds of roasted foods; yam (Dioscorea Rotundata ) and plantain (Musa Paradisiaca) commonly consumed in Nigeria. Yam and two variants of plantain (unripe and ripe) were considered for this study. Two grilling heights (10 cm and 20 cm) were employed on each of ...

Impact of Cooking Methods on the Levels of Polycyclic Aromatic Hydrocarbons (PAHs) in Chicken Meat

Abstract: This study investigated the presence of polycyclic aromatic hydrocarbons (PAHs) in the different cooking methods of chicken. The levels of 16 PAHs compound were determined in raw and cooked chicken meats. The chicken was cooked with different methods, i.e. boiling, frying, barbequing and roasting. The uncooked sample served as the reference. With the aid of the 16 PAHs reference standards, the levels of the PAHs were determined using gas chromatography - flame ionization detecto...

Assessment of Surface Water Contamination and Effect of Textile Effluents on Ibeshe River, Ikorodu, Lagos State, Nigeria

ABSTRACT An increased concern in recent times has been the effect of industrial effluent discharge into the water bodies. Surface water samples of Ibeshe River were studied to find out the pollution load of wastewater generated from the textile industry and its impact on the quality of the receiving river. Water samples were collected at four (4) different points for each of the three (3) steam divisions (the upstream, the midstream and the downstream) bimonthly within one year; 3 months ...

Impact of Textile Wastewater on Whole Plants of Corchorous olitorius, Telfairia occidentalis, Celosia argentea and Amaranthus hybridus Cultivated within Farmlands in Ibeshe, Ikorodu, Lagos St

Abstract Soil contamination with heavy metal due to discharge of untreated or incompletely treated industrial effluent is a threat to the ecosystem and human well-being. The effect of textile waste effluent on four vegetable plants (Corchorous olitorius, Telfairia occidentalis, Celosia argentea and Amaranthus hybridus) cultivated within farmlands located along the Abuja River in Ibeshe town near Ikorodu, Lagos State was investigated. Their heavy metal levels were determined using atomic a...

Essential Oils and Fatty Acids Composition of Dry Fruits of Tetrapleura tetraptera

ABSTRACT: The composition of essential oil and fatty acids of dry fruits of Tetrapleura tetraptera were analyzed by GC/MS. Forty-four compounds representing 98.5% of the essential oil were characterized. The essential oil was dominated by acetic acid (34.59%), 2-hydroxy-3- butanone (18.25%), butanoic acid (8.35%), 2-methyl butanoic acid (7.58%), 2-methyl butanol (7.45%), butanol (4.30%), 2-methyl butenoic acid (3.65%) and Nerol (3.25%). The fatty acid was dominated by palmitic acid (49.4...

Determination of the cyanide content in some bitter cassava species in parts of Ohimini L.G.A of Benue State

This project work was carried out to determine the cyanide content in some bitter cassava species in parts of Ohimini L.G.A of Benue State and finding out the best method to considerably reduce the high content in the cassava.

Assessment of Heavy Metals in The Muscle of Domestic Birds

Abstract— The main objective of the present study was to provide the information on the concentration and distribution of manganese (Mn), iron (Fe), copper (Cu), zinc (Zn), cadmium (Cd) and lead (Pb), in the muscle of different species of domesticated birds  (guinea fowl, Local fowl, Cockerel) considering both male and female species using  Atomic absorption spectrophotometry. Initially, the samples were digested with concentrated nitric acid, Hydrogen peroxide and Perchlori...

AN OVERVIEW OF TUMOUR MARKERS

ABSTRACT Tumor Markers comprise a wide spectrum of biomacromolecules synthesized in excess concentration by a wide variety of neoplastic cells. The markers could be endogenous products of highly active metabolic malignant cells or the products of newly switched on genes, which remained unexpressed in early life or newly acquired antigens at cellular and sub-cellular levels. The appearance of tumor marker and their concentration are related to the genesis and growth of malignant ...

EVALUATION OF EXCESSIVE LIFETIME CANCER RISK DUE TO NATURAL OCCURRING RADIONUCLIDES AND HEAVY METALS IN LAGOS BEACH SEDIMENT WORK

AbstractsEvaluation of anthropogenically enhanced naturally occurring radionuclides 238U, 232Th and 40K present in Lagos beach sediment (Eleko and Elegushi) were analyzed with gamma ray spectrometer using a highly shielded NaI (TI) detector with the objective of evaluating the environmental radiological hazard. Mineralogical analysis and characterization was also carried out using Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) technique. Heavy metals such as Pb, Cd...

Determination of levels of lead in paints to which young children and adults are exposed.

The Paint samples were gotten from old houses in areas of Ikorodu, Onipan, Lekki, Berger, Agbado-Ijaye, Lagos Island, Moremi and Makama hall (University of Lagos) and were digested using three different methods, which include1) Nitric acid and per-chloric acid digestion2) Nitric acid and hydrogen peroxide digestion3) Dry ashing digestion using muffle furnace    These methods were compared and was discovered that oil - based paints (gloss paints) has higher concentration of lead than...

COMPARATIVE DETERMINATION OF CALCIUM AND MAGNESIUM IN FOOD SUBSTANCES USING EDTA-TITRIMETRY AND FLAME ATOMIC ABSORPTION SPECTROMETRY (FAAS)

A comparative study was carried out for the determination of calcium and magnesium in milk and water melon (food sources of calcium and magnesium). Mixed standard solutions of calcium and magnesium (spike) were added to the samples before digesting with a mixture of concentrated nitric acid and concentrated hydrochloric acid (1:3). The calcium and magnesium content of the digest were determined using flame atomic absorption spectrophotometer (FAAS) and EDTA titration. The percentage recovery ...

ABSTRACTThis research paper analyses the physical and chemical parameters of water sample collected from Jakusko local government area, Yobe State. It is predicted that the water in this area may be the cause of kidney problem people have been suffering from, this is why we decided to embark on this research work to enable us ascertain wither the water is the main cause of the kidney problem in the area. The water sample collected is from the following areas: mai yandu street, mai anguw...

Laboratory Preparation and Analyses of Ochre Soaps with Characteristic Medicinal Effect on Dermatophylosis

ABSTRACTFour oil namely palm kernel oil, palm oil, ground nut oil and shear butter oil were employedin the production of ochre soap. Dermatophilus congolensis were used as organism to test foranti-bacteria or medicated activities of this soap. The physical properties of the soap samplessuch as colour, texture and foaming were determine. The chemical properties such as acidvalue, percentage free alkalinity, percentage insoluble matter, percentage moisture and pHvalue were determined. It was fo...
