In this study, for the first time, the use of DNA barcoding was used in identification of the genetic diversity of fish in Ugwu-omu Nike River, Enugu State, Nigeria. The fish were collected and placed in an aquarium and later transported to the Biotechnology laboratory of Godfrey Okoye University. The fish collection was followed by identification...

Nitrogen dioxide (NO 2) is the only widely prevalent coloured pollutant in the atmosphere. The assessment of ambient air quality with special reference to NO 2 was carried out in this study at the waste dump site in Osisioma Ngwa Local government Area in Nigeria during the morning and Evening hours of the dry season. Average Air Quality Index (AQI)...

Antimicrobial activity of secondary metabolites of fungi isolated from leaves of Bush mango against some selected microorganisms (Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis, Penicillium chrysogenum and Aspergillus fumigates) was carried out in this study. Agar well diffusion method was used to study the antim...

In this present study, bacteria were isolated from soil obtained from oil contaminated mechanic site in Enugu. Out of the 206 forming colonies, 16 colonies were selected based on observable morphological differences and screened for crude oil degraders. Out of the 16 isolates, 11 isolates were assumed to be degraders because they formed maximum cle...

Water plays an important role in determining the quality of life on earth and yet this role is threatened by indiscriminate discharge of industrial effluents. The study aimed to assess the potential impact of industrial effluents from Saclux paint industry on the water quality of Nkoho River in Abia state, Nigeria. Water samples were taken at the e...

This study investigated the presence and concentrations of volatile organic compounds (VOCs), SO2, particulate matter (PM), O3, NO2, and CO in the indoor environment of a general hospital—Federal Medical Centre, Umuahia in Abia State, Nigeria using the following sampling sites: Accident and Emergency ward (A and E), Intensive Care Unit (ICU), Main...

This study assessed the concentrations of heavy metals in soil and surface water from a Lead-Zinc mined pit at Enyigba, Ikwo Local Government Area in Ebonyi State, Nigeria. Soil samples were collected and analysed from different soil depths (0 – 15 cm) and (15 – 30 cm) at a tailing down (marked as TD) and refuse dumpsite (marked as RD) and a vegeta...

Microbial assessment of indoor air quality of a tertiary health care institution.

The study was conducted at waste dumpsite in Umuahia, Abia State, Nigeria to ascertain its toxicity levels in relation to the surrounding environment. Five leachate samples (L1 to L5) were randomly sampled in triplicate from the actual leachate streams in the solid waste dumpsite using Complete Randomized Design to assess the toxicity in leachate i...

Herbal soap has been found to be effective against most microorganisms because it is mostly formulated from plants. This study aimed at formulating herbal soap from paw paw (Carica papaya) leaf extract (Caricapapaya) tested against 3 microbial isolates: Staphylococcusaureus,Pseudomonasaeroginosa and Candidaalbicans using agar well diffusion method....

Noise pollution continues to grow and is accompanied by an increasing number of complaints including discomfort and irritation to people depending on its intensity, duration and frequency., Ambient noise levels was sampled from different points around three major markets in Umuahia by noise level meter Extech 407730. The instruments were calibrated...

Targeting parasite's protein kinase Malaria elimination goals are constantly eroded by the challenge of emerging drug and insecticide resistance. Alam et al. have taken established drug targets—CLK protein kinases involved in regulation of RNA splicing—and investigated how inhibition of the parasite's enzymes blocks completion of its complex life c...

Juveniles of the African Catfish, Clarias gariepinus were exposed to refined petroleum product {kerosene (0, 0.2%, 0.4%, 0.6%, 0.8% and 1.0%)} in replicate for in situ static bioassay studies. Twelve (12) aquaria glass tanks were also used for the study. The test organisms were acclimatized in the laboratory for two weeks (14 days) in the glass aqu...

Alternative medicines, such as herbal medicines, are now gaining popularity globally, especially because of typically low side-effect, low cost and high level of acceptance by patients. This study evaluated the antibacterial properties of some liquid herbal anti-infective drugs produced and marketed in Enugu, SouthEast Nigeria and estimated their l...

There has been remarkable industrial development in Nigeria over the past two decades arising from the establishment of many industries at different locations in the country. This rapid rate of industrialization has not been matched with proper environmental monitoring for the control of pollutions at industrial wastes dumpsites, especially in the...

Molds are beneficial to the environment and are needed to break down dead materials. Very tiny and lightweight, mold spores travel easily through the air. Most building surfaces can provide adequate nutrients to support the growth of mold. They are microscopically small plant-like organisms, composed of long filaments that grow over the surface of...

The study evaluated the atmospheric corrosion of corrugated iron roofing sheets in rural, urban, and marine environments using rain water harvested from roofs of various ages. Corrosion study was based on the weathering processes leading to high levels of sulphate, chloride and nitrate in rainwater in the three areas. Results showed that roofs belo...

Nitrogen dioxide (NO 2) is the only widely prevalent coloured pollutant in the atmosphere. The assessment of ambient air quality with special reference to NO 2 was carried out in this study at the waste dump site in Osisioma Ngwa Local government Area in Nigeria during the morning and Evening hours of the dry season. Average Air Quality Index (AQI)...

ABSTRACT Despite the practice of domestic rainwater harvesting (DRWH)for d omestic purposes, little or no effort has been made toward monitoring the quality of stored rainwater in storage tanks in Owerri, Imo to ascertain their impacts on domestic harvested rainwater quality (DHRWQ). During the study, samples of harvested rainwater were collected...

The use of Chlorella species for bioremediation of diesel oil spillage was carried out in the study using gravimetric analysis. From the study, experimental setup C Group 4 showed more growth and degradation than the others. The Chlorella sp. degraded a maximum of 33.3% diesel oil after 30days of incubation. This was followed by 32% in experimental...

Groundwater samples were taken from Oboro community to evaluate the hatchability and survivability of African Catfish (Clarias gariepinus) broodstock of average weight 1.16kg for male and 1.15kg for female. The percentage (%) fertility and hatchability were determined subjectively after 12hours of fertilization. Survival percentage (5) was evaluate...

Crude oil contamination leads to unmanageable extent of loss of biological life that has several negative impacts on global economy. Intensified physical and chemical clean-up and prevention technologies have found temporary solutions. But present study had revealed that almost complete removal can be possible by bioremediation using microorganisms...
