                      Abstract Polycyclic aromatic hydrocarbons, heavy metals and physiochemical parameters were measured in water samples from zaakpon community. The results shows that most of the parameters in water were within safe limits except turbidity, potassium and Phosphate while PAHs concentrations in water were below... Continue Reading

ABSTRACT Five different filling stations (Station A, Station B, Station C, Station D and Station E) were analyzed for Total Petroleum Hydrocarbons and heavy metals concentration using Gas chromatography–mass spectrometry and atomic absorption spectrophotometer respectively. The result of the analysis obtained indicated that the percentage range... Continue Reading

ABSTRACT A study of the effect of biochar (charcoal) on microbial colonization and heavy metal concentration in polluted soil was conducted for eighth (8) weeks between September to October, during the cropping season of 2018, at the faculty of Agriculture, Kogi State University, Anyigba. The aim of the study was to determine the effect of biochar... Continue Reading

The aim of this research is to determine the level of heavy metals contamination of agricultural soil and to reduce its concentration in the soil. Soil sampled at Inua Eyet Ikot, Mkpanak, Ibeno Local Government Area of Akwa Ibom State was analyzed to check for the initial heavy metal concentration of the soil. Poultry litter as a nutrient additive... Continue Reading

ABSTRACT This study was initiated as a follow-up information on some impounded products tomato puree (Samples A and B) chocolates and candies (Samples C, D, E and F) imported from China, and sold in Nigerian markets. This result as their failure to meet National Agency for food drug administration and control (NAFDAC) regulatory standard. Samples... Continue Reading

The concentrations of Ni, Mn, Cd, Cu, Zn, Pb and Cr, were determined in some pastas consumed in Nigeria, with a view to providing information on the dietary intakes of heavy metals and exposure of humans to toxic metals. The concentrations of these seven (7) elements were determined by atomic spectrometry after nitric acid/perchloric acid... Continue Reading

ABSTRACT This study was done to evaluate the risk of heavy metals pollution of soils within the vicinities of refuse dumpsites in Calabar south, LGA. Soil samples were collected from a depth of 0-20cm with the use of a soil auger from ten (10) dumpsites using the stratified sampling method.   The samples were well labelled in polythene bags and...

ABSTRACT The soils and leaves of fluted pumpkin (Telfairia occidentalis), African spinach, 'Green' (Amaranthus hybridus) and water leaf (Talinum triangulare) were collected as randomly composite samples from four (4) different study locations of two (2) each from Owo Local Government Area and Etsako-West Local Government Area. The samples were... Continue Reading

ABSTRACT The toxicity of heavy metals to humans as a result of long term exposure to pollutants consumer products such as cosmetics and other pollutants has been established. In this study, the levels of heavy metals in different cosmetic products commonly used among Kaduna Polytechnic students were assessed. The cosmetics were analyzed for heavy... Continue Reading
