Comparative Profiling and Bioaccumulation of PAHs in Soil and Talinum triangulare Harvested from Charcoal Production Areas in Southern Nigeria

This study investigated the comparative profiling and bioaccumulation of PAHs in soil and Talinum triangulare harvested from charcoal production areas in Southern Nigeria. T. triangulare was cultivated in three sites (1, 2 and 3) in a charcoal production environment for seven weeks.

Phycoremediation of Laundry Wastewater Using Chlorella vulgaris (Beijerinck)

A study of the effect laundry wastewater on the microalga Chlorella vulgaris was carried out. The study was carried out using different treatments 0% (control), 5%, 10%, 20%, 30%, 40%, 50% of laundry wastewater. The microalgal growth responses were determined optically using absorbance on spectrophotometer at 750nm.

Assessment of the Water Quality of Selected Boreholes Close to a Dumpsite in Agbor Metropolis, Delta State, Nigeria

Dumpsite utilization for municipal solid waste disposal produces leachate which is a threat to groundwater resources. The study was aimed at determining the suitability of groundwater for drinking and domestic usages using physical, chemical and microbial indices, with a view to assessing the vulnerability of boreholes close to dumpsite to groundwater pollution. The results showed that except for pH and lead, the concentrations of other physico – chemical parameters were within acceptable limits of NSDWQ and WHO.

Spectroscopic investigation of heavy metals in waste water from University students’ halls of residence

Although there is increased global concern on sustainable environmental and human health management, the African countries are still unserious which should not be the case considering the potential consequences of harmful chemicals discharge into our environment from domestic and other anthropogenic activities. We are therefore reporting in this paper a spectroscopic assessment of heavy metals in wastewater generated from students’ halls of Usmanu Danfodiyo University Sokoto, Nigeria.

Impact of Accumulation and Deposition of Some Heavy Metals in the Tissues of Leaves, Shoots and Roots of Paspalum scrobiculatum and Azonopus compressus

Paspalum scrobiculatum and Azonopus compressus were used to study the accumulation and deposition of lead in tissues of roots, rhizomes and leaves, as well as their impact on changes in the anatomy of their tissues. Four (4) kg of air dried soil was measured into Four (4) kg perforated plastic buckets. Waste engine oil was added to Four (4) kg different soil samples to obtain different concentrations on weight basis: 0% (control), 2%, 4%, 7% and 10% v/w oil-in-soil and allowed to stand for seven days before transplanting. The plants were harvested after 8 weeks of transplanting.

Phytotoxicity Study on the Effects of Waste Engine Oil on the Anatomy of Sataria barbata (LAM.) KUNTH and Brachiaria deflexia (SCHUMMACH.) C.E. HUBB. EX ROBYNS

The present study explored the use of anatomical characters of Sataria barbata and Brachiaria deflexia as indicators of waste engine oil pollution. Four (4) kg of air dried soil was measured into perforated plastic buckets and treated with waste engine oil to obtain different concentrations [0% (control), 2%, 4%, 7% and 10%] on volume to weight basis. The experiment was set up in 3 replicates. The soil samples were allowed to stand for seven days before seedlings were planted. The plants were harvested after 8 weeks of transplanting.

Screening for Biodegradative Activity of Diesel Oil by Microorganisms Isolated from Petroleum Polluted Soil of a Mechanic Workshop at AKAD Community, Akure, Nigeria

The present study explored the use of anatomical characters of Sataria barbata and Brachiaria deflexia as indicators of waste engine oil pollution. Four (4) kg of air dried soil was measured into perforated plastic buckets and treated with waste engine oil to obtain different concentrations [0% (control), 2%, 4%, 7% and 10%] on volume to weight basis.The experiment was set up in 3 replicates. The soil samples were allowed to stand for seven days before seedlings were planted. The plants were harvested after 8 weeks of transplanting.
