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...
