Efficacy of heat-treated glycine max husks in crude oil removal from simulated and real contaminated waters: modeling, regeneration and reusability

Autor: Ikeokwu Chris Ogbu, Cynthia Nkolika Ibeto, Chukwuma Obiajulu B. Okoye

Publikováno v: Petroleum Science and Technology. :1-16

The treatment of oil spilled water surfaces using raw glycine max husks (RGMH) and carbonized glycine max husks (CGMH) were reported. The sorbents were characterized by BET, TGA, FTIR and SEM techniques. The sorption of oil was by batch method. The e

Environmental impact and human health risk assessment of polycyclic aromatic hydrocarbons (pahs) in raw milk from free-ranging cattles in northwest nigeria

Autor: C. O. B. Okoye, Hillary Onyeka Abugu, Aliyu Turaki Usman

Publikováno v: J Environ Health Sci Eng

Polycyclic aromatic hydrocarbons (PAHs) were determined in raw milk from Northwest Nigerian cattle (cow, goat and sheep) as indicators in assessing the current pollution status of the region. In Northwest Nigeria, most animals are free rangers with t
