A conceptual model outline for integrated exposure assessment of waste disposal sites

28-Jan-2011 | Butt, T.E.; Ingles, A.J.D.; Baloch, M.I., Environmental Progress, 2011

Abstract There are generic elements in environmental risk assessments, which are independent of the subject to which risk analysis is applied. Examples of these elements are as follows: baseline study, hazard identification, hazards' concentration assessment, risk quantification, etc. Another ...

How Mobile Are Sorbed Cations in Clays and Clay Rocks?

24-Jan-2011 | T. Gimmi; G. Kosakowski, Environmental Science & Technology, 2011

Diffusion of cations and other contaminants through clays is of central interest, because clays and clay rocks are widely considered as barrier materials for waste disposal sites. An intriguing experimental observation has been made in this context: Often, the diffusive flux of cations at trace ...

Quantifying the Total Environmental Impacts of an Industrial Symbiosis - a Comparison of Process-, Hybrid and Input−Output Life Cycle Assessment

27-May-2010 | Tuomas J. Mattila; Suvi Pakarinen; Laura Sokka, Environmental Science & Technology, 2010

Industrial symbiosis, representing resource sharing and byproduct use among colocated firms, is a key concept of industrial ecology. Local co-operation in industrial symbioses can reduce raw material use and waste disposal, but material and energy flows extending outside symbiosis boundaries can ...
