Enhanced remediation of an oily sludge with saline water
This study investigates the potentials of saline (that is, brackish) water to enhance the remediation of an oily sludge, which was part of the waste stream from the improvement project of the Tank Farm at the Bonny Island in the Niger Delta region of Nigeria. Twice weekly, five separate laboratory-scale reactors (labeled A, B, C, D and O), each containing 2.0 × 10-2 m3 of the diluted sludge...

Inhalable particulate matter associated with mining and smelter activities
The objective of this study was to determine the mass concentration levels of the inhalable air particulate matter (PM10) and the effect of meteorological parameters on the dilution and dispersion thereof. The PM10 was collected using Tapered Element Oscillating Microbalance (TEOM) and the concentrations were determined at two sampling sites RMINE and RCBD within the Rustenburg area. The hourly levels for...

Heavy metal speciation and their accumulation in sediments of Lake Burullus, Egypt
Several sediment samples in Lake Burullus have been affected by the discharges of heavy metals through different drains. The study aimed to analyze the chemical speciation of these metals. In particular, the chemical forms of Cd, Cu, Fe, Mn, Pb and Zn in sediments collected in spring season were studied using a sequential chemical extraction method. In general, all the elements recorded highest...

Fluoride removal from aqueous solution by pumice: case study on Kuhbonan water
The fluoride removal from synthetic water by pumice was studied at batch experiments in this study. The effect of pH, contact time, fluoride concentration and adsorbent dose on the fluoride sequestration was investigated. The optimum conditions were studied on Kuhbonan water as a case study. The results showed that with increasing of the absorbent amount; contact time and pH improve the efficiency of fluoride...

Characterization of groundwater in the Souss upstream basin: Hydrochemical and environmental isotopes approaches
The hydrochemistry of major ions and environmental isotope compositions (18O, 2H) of water samples have been used to identify the chemical characteristics and the origin of groundwater in the Souss upstream basin. The total dissolved solids (TDS) did not exceed 1000 mg.L-1 with an average of 635 mg.L-1. Two chemical water types were observed: A calcium and magnesium bicarbonate...

The phytosociological analysis of saline area of Tehsil Ferozewala, District Sheikhupura (Punjab)Pakistan
This study is a broad ecological survey, and classification of the vegetation of Agro Farm plantations of a Tehsil Ferozewala (District Shei khupura) Punjab, Pakistan. The vegetation survey description and classification was according to Zurich-Montpellier School of thought is based on over 300 Relevé Method. In all twelve associations i.e. Suaedetum fruticosae,Kochietum indicum Diplachnetum...

Empirical research on constructing Taiwan’s eco-environmental stress indicators system
In this paper, the material flow indicators and ecological footprint approach structured are adopted to construct eco-environmental stress indicators. We use relevant data to proceed with the empirical analyses on environmental stress and ecological impacts in Taiwan between the years of 1998 and 2007. Analysis of research results brings several important findings. (1) Taiwan’s economic activities...
