Research ArticleOpen accessIn the abstractEvaluation of Hydrogen/Oxygen Release Compounds for the Remediation of VOCsS. Fiore, M.C. ZanettiProblem statement: Volatile Organic Compounds (VOCs) were widespread in groundwater of industrialized areas and in situ remediation intervents characterized by a high environmental compatibility were of main interest. The scope of this study was the evaluation of the potential of two innovative reagents (HRC and ORC from Regenesis) for the remediation of Volatile Organic Compounds (VOCs). The reagents respectively perform … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 4 Nov 2011 · 7,440 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemediation Technologies for Marine Oil Spills: A Critical Review and Comparative AnalysisD. Dave, A.E. GhalyProblem statement: Anthropogenic activities pollute the oceans with oil through land run off, vessels accidents, periodic tanker discharges and bilge discharges. Oil spills are environmental disasters that impact human, plants and wild life including birds, fish and mammals. Approach: In this study, the International Guidelines for Preventing Oils Spills and Response to Disasters were reviewed and the characteristics of oil … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 2 Nov 2011 · 25,617 accessesView PDFCite
Research ArticleOpen accessIn the abstractRelationship between Affordances in the Home Environment and Motor Development in Children Age 18-42 MonthsAlireza Haydari, Parviz Askari, Maryam Zarra NezhadProblem statement: Environmental stimulation plays a critical role in optimal human development during the early stages of life and an optimal level (of development) occurs with strong contextual support. It is well accepted among develop mentalists that motor-perceptual-and cognitive development are fundamentally interrelated. This suggests that status of motor development is an important factor in overall child well-being. The objectives … …Journal of Social Sciences, Vol. 5, Issue 4 · 31 Dec 2009 · 9,631 accessesView PDFCite
Research ArticleOpen accessIn the abstractSuitability of Using Phragmites australis and Tamarix aphylla as Vegetation Filters in Industrial AreasWafa’a A. Al-TaisanProblem Statement: Many soils of different areas of the world are subjected to heavy metal pollution due to human activities especially the industry. These metals are hazardous to human health and could affect ecosystems. Toxic metal pollution in water and soil is a major environmental problem and most conventional remediation approaches do not provide acceptable solution, hence the studies of … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 8,450 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Assessment of Metals (Pb and Cu) Contamination in Bottom Sediment from South China Sea Coastal Waters, MalaysiaM. C. Ong, B. Y. KamaruzzamanProblem statement: The accumulation of metal contaminants in sediments can pose serious environmental problems to the surrounding areas. Trace metal contamination in sediment could affect the water quality and the bio-assimilation and bioaccumulation of metals in aquatic organisms, resulting in potential long-term implications on human health and ecosystem. Approach: About 154 bottom sediment samples were collected using Smith McIntyre in … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,995 accessesView PDFCite
