Comparative study of biogas production from chemically-treated powdered and un-powdered rice husks

  Biogas production was carried out using fresh powdered rice husk (PRH), un-powdered rice husk (U-RH) and a blend of both (CRH) in the ratio 1:1. They were left to degrade for 73 days before pre-decaying in water. The pre-decayed wastes were found to be acidic. Consequently, a concentrated solution of potassium hydroxide (KOH, 50%w/v) in acetic acid (CH3COOH, 99% v/v) was used to treat the wastes to achieve...

Risk assessment of using coated mobile recharge cards in Nigeria

  The risk assessment of coatings on mobile phone recharge cards on end users has been investigated using mobile phone recharge cards of three major brands (designated as A, B and C) with dominations of N200, N400 and N500 purchased from retail shops in Zaria, Nigeria. To appraise the health risk associated with heavy metal contamination of food by metals from the coatings, Daily Intake...

Evaluation on rare earth elements of Brazilian agricultural supplies

  This work focuses on the determination of rare earth elements (REE) in Brazilian agricultural supplies by instrumental neutron activation analysis (INAA). The results obtained have shown that La, Ce, Nd, Sm, Eu, Tb, Yb, Lu and Sc are present within a large range of mass fractions in the agricultural supplies analysed. The thermophosphate and single superphosphate showed the highest mass...

Airborne particulate matter (PM10) composition and its genotoxicity at two pilgrimage sites in Makkah, Saudi Arabia

  Airborne particulate matter (PM10) contains a large number of genotoxic and carcinogenic substances. Ambient air is reported to be mutagenic in many areas worldwide. Particulate matter has been linked to premature mortality, lung cancer, respiratory and cardiovascular health problems. In the present study, we investigated the genotoxicity of the ambient air PM10 extractable organic matter (EOM)...
