Methods for determination of hexachlorobenzene and pentachlorophenol in soil samples
(Elsevier B.V., 1998-08-01)
The efficiency of methods for the determination of hexachlorobenzene (HCB) and pentachlorophenol (PCP) in soil samples was evaluated. An on-line method was applied for HCB determination. Soil samples were transferred to ...
Decarbonization tradeoffs: A dynamic general equilibrium modeling analysis for the chilean power sector.
Medium size developing countries like Chile that commit to decarbonization goals need to carefully assess the trade-offs associated to their intensity and timing, since most of the technologies required will be absorbed, ...
