Soil samples collected from two major dumpsites each in Kano and Kaduna states were investigated for heavy metals pollution. Each of the dumpsite was divided into north, south, east and west. Four soil samples were collected at a depth of 0-15 cm from each part and pooled to form a composite sample. Soil samples from reserve areas within the same geographical locations as the dumpsites were col...

The study examined the problem of waste disposal and management in Ughelli. A field survey was undertaken to determine the types, volume, effects and methods of managing solid waste in the Ughelli. The volume of waste was measured at dumpsites in the four existing quarters and from household bins. Appropriate waste characterization methods were employed in classifying the waste into various com...

This retrospective cohort study evaluated adverse birth outcomes in infants whose birth records indicated maternal residence in villages containing dumpsites potentially hazardous to health and environment. Birth records from 1997 to 2001 identified 10,073 eligible infants born to mothers in 197 Alaska Native villages. Outcomes included low or very low birth weight, preterm birth, and intrauter...

Ceramic Bonding, Inc. (CBI) was founded in 1987 to develop technology for reliable, inexpensive, on-site conversion of heavy metal hazardous wastes to safe, useful materials, such as fine aggregate for construction applications. CBI’s principal mission is to provide equipment that can be used by industry to eliminate the need for costly and environmentally unwise disposal of toxics at Class I d...

Synthetic fluorspar can be produced from waste calcium fluoride slurry settled on dumpsites located near Cracow centre. Synthetic fluorspar exchanges natural raw material used in the metallurgical industry. To obtain grained synthetic fluorspar, calcium fluoride slurry should be calcinated in rotary kilns at temperatures of 900-1100K. Grain size and compression strength strongly depends on calc...

The environmental risks associated with heavy metal pollutions are becoming worrisome. Hence, this study evaluated the and human health of lead (Pb) accumulation in soil samples from solid waste dumpsites within Abuja, Nigeria. Soil (n=72) were collected (0-45 cm depth) Abaji, Bwari, Gosa, Gwagwalada, Kuje, Kwali 2 km away (control), then analyzed for Pb using atomic absorption spectrophotomete...

In order to monitor Potentially Toxic Elements (PTEs) in anthropogenic soils on brown coal mining dumpsites, a large number of samples and cumbersome, time-consuming laboratory measurements are required. Due to its rapidity, convenience and accuracy, reflectance spectroscopy within the Visible-Near Infrared (Vis-NIR) region has been used to predict soil constituents. This study evaluated the su...

Degradation of Askarel (PCB Blend) by Indigenous Aerobic Bacteria Isolates from Dumpsites in Ore, Ondo State.Nigeria. Nwinyi, Obinna C Department of Biological sciences, School of Natural and Applied Sciences, College of Science and Technology, Covenant University, Km 10 Idiroko Road, Canaan land PMB, Ota, Ogun State, Nigeria. Abstract: The removal of toxic industrial products such as polychlor...

This study aimed to evaluate concentrations of selected heavy metals in the soils of Ilokun dumpsite and adjourning farmlands, and to determine as well levels of heavy metals uptake in various parts of Carica papaya plant collected from the dumpsite. Twenty-two soil samples were collected within the dumpsites and farmlands at depths of 0-20 cm and 20-40 cm. Evaluations of heavy metals ...

Living near landfills is a known health hazard prompting recognition of environmental injustice. The study aim was to compare self-reported symptoms of ill health among residents of four neighborhoods, living in haphazardly constructed settlements surrounded by illegal dumpsites in Tijuana, Mexico. One adult from each of 388 households located in Los Laureles Canyon were interviewed about demog...
