2. 1. Stormwater Ponds for Pollution Reduction

   Author : Thomas Pettersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; suspended solids; reduction; pollution; stormwater pond; flow modelling; FEM; field measurements; heavy metals; nutrients;

   Abstract : Stormwater transports particulate-bound and soluble pollution from urban areas to receiving waters during rain events. Measurements have shown that open detention ponds, originally used for flood control, effectively reduce stormwater pollutant load and have therefore been increasingly used for stormwater treatment.

   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Forest sector; Forest fuels; Dynamic factor demand; Adjustment costs; Economic growth; Pollution; Environmental Kuznets curve; Shadow price; Distance function; Nationalekonomi; Economics; Nationalekonomi; Economics; nationalekonomi;

   Abstract : This thesis consists of four papers: two of them deal with the effects on the forest sector of an increase in the demand for forest fuels, and two of them concern the relation between economic growth and pollution. Paper [I] is a first, preliminary study of the potential effects on the Swedish forest sector of a continuing rise in the use of forest resources as a fuel in energy generation. READ MORE

   Abstract : Waterborne pollution from mining is impacting groundwater and surface water resources in many regions of the world. Main problems include acidification and high levels of dissolved toxic metals that adversely affect humans and ecosystems. READ MORE

6. 4. Virtual Mobility and Pollution Prevention - The Emerging Role of ICT Based Communication in Organisations and its Impact on Travel

   Author : Peter Arnfalk; Internationella miljöinstitutet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; pollution control; Environmental technology; travel reduction; pollution prevention; telework; web-meetings; audioconferencing; videoconferencing; virtual mobility; virtual communication; IT; IKT; ICT; Miljöteknik; kontroll av utsläpp; Informatics; systems theory; Informatik; systemteori; Telecommunication engineering; Telekommunikationsteknik;

   Abstract : Information and Communication Technologies change the way we work and communicate, enabling us to telework and to have virtual meetings - collaborating without a physical meeting. This can influence the need for commuting and business travel by provision of access to an activity without mobility - virtual mobility. READ MORE
