Title

Origin and Speciation of Selected Trace Elements in Groundwater: A Case Study of Azzaba District in Northeast of Algeria

Abstract

Azzaba District is a key area of heavy metal contamination in Northeastern Algeria. Mercury, among other metals, is an environmental issue of this locality, particularly due to its potential impact on environment as well as human health. Ecosystem of Azzaba is constrained by the original As-Hg-Sb-Pb-Zn sulphide mineralization, the specific topography, hydro-geomorphology and by the disturbance of human activity. Seventeen groundwater samples were collected from domestic hand dug wells in the study area Basin and analyzed to understand the chemical composition, character and chemical speciation of Azzaba shallow groundwater. Results show that Hg, Pb, Cu and Zn were identified as contaminants of potential environmental concern in almost all groundwater samples. The geochemical modelling conducted to investigate the possibility of metal precipitation and formation of secondary minerals, shows a supersaturation with respect to calcite and dolomite and undersaturation in halite, gypsum and anhydrite; the most abundant primary mercury mineral phases of Azzaba shallow groundwaters are HgC12, Hg2C12, Hg, HgSO4 and Hg2SO4. The results of the model also shows a supersaturation with common acid mine drainage minerals such haematite, goethite, magnesioferrite and lepidocrocite.

The Trophic Status of the Main Rivers and Reservoirs of the Wang River, Thailand

Abstract

The trophic status of main rivers and reservoirs of the Wang River, Thailand were investigated every month for a year from October 2011 to September 2012. Water samples were collected from 12 sites located along the main rivers and reservoirs of the Wang River, with sampling sites from upstream to downstream. At each site, some physical and chemical parameters were studied and the water quality was classified based on the trophic status. It was found that the water quality at most of the sampling sites was not clearly different and could be classified as clean to moderate (oligotrophic-mesotrophic status). However, the water quality at the urban sites was different and could be classified as moderate water quality (mesotrophic status). In addition, in this study, it was found that the reservoirs of the Kiew Kor Ma Dam and the Kiew Lom Dam contributed to the improvement of the water quality by decreasing the concentrations of SRP and ammonium -nitrogen that originated from the river.

Title

Awareness, Attitude and Practice of School Students towards Household Waste Management

Abstract

The topic of environmental protection has attained highest importance in this era globally but the practices of basic concepts waste disposal are often neglected. People around the globe are aware of the impact of improper waste disposal practices, but the negative attitude of implementation gives rise to chaotic situations. This study was conducted to obtain baseline information about waste management practices among school children in Kerala. This cross sectional study was conducted using a well designed and validated questionnaire. Out of one thousand students of a high school and higher secondary school from Thrissur City in Kerala, 300 were randomly selected. The data analyzed using student t-test showed, high school students are more aware about household waste management than the higher secondary school students. It is evident from this study that there is significant difference between awareness and practice. Our study reveals the necessity of giving mass awareness to the impact of waste disposal practices from the beginning of school education. Committed environmental education will inculcate a proper and appropriate environmental culture in the students. As the study revealed awareness of e-waste disposal is lacking there is an urgent need to rectify this gap in knowledge and practice.
