  2. 11. Analytical method development for ultra-trace determination of human pharmaceuticals in aqueous samples. Assessing the performance of a sewage treatment plant

    Author : Saioa Zorita; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecularly imprinted solid-phase extraction; Sample preparation; solid-phase extraction; membrane extraction; human pharmaceuticals; sewage treatment plant; steroid hormones;

    Abstract : Research focus in environmental pollution has recently been extended from more classical environmental pollutants such as PCBs or pesticides to pharmaceuticals and steroid hormones, which are designed to be biologically active and enter the environment primarily through regular domestic use. Consequently, it is important to monitor these substances concentrations in the effluents of sewage treatment plants (STPs) and in the environment in order to evaluate their associated risks.

  4. 12. Levels and sources of organophosphorus flame retardants and plasticizers in indoor and outdoor environments

    Author : Anneli Marklund; Peter Haglund; Barbro Andersson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organophosphate esters; OPs; human exposure; air; dust; sewage treatment plants; sludge; oil; snow; deposition; flame retardants; plasticizers; analysis; TCEP; TPP; TCPP; TBP; TBEP; Environmental chemistry; Miljökemi;

    Abstract : Global consumption of organophosphate esters (OPs), which are used as flame retardants and plasticizers, is rapidly increasing. Their use as additives in diverse applications poses a risk as they may be emitted from the products they are added to and be further transported in the environment. READ MORE

  5. 13. Phosphorus release and recovery from treated sewage sludge

    Author : Kristina Stark; Elzbieta Plaza; Bengt Hultman; Jes la Cour Jansen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ash; Phosphorus release; Phosphorus recovery; Sludge fractionation; Supercritical water oxidation; Sustainable sludge handling.; Water engineering; Vattenteknik;

    Abstract : In working towards a sustainable society, recycling and recovery of products together with handling of scarce resources must be considered. The growing quantities of sludge from wastewater treatment plants and the increasingly stringent restrictions on landfilling and on agricultural use of sludge are promoting other disposal alternatives.

  6. 14. Genetic Aspects of Environmental Disturbances in Marine Ecosystems : Studies of the Blue Mussel in the Baltic Sea

    Author : Josefine Larsson; Mats Grahn; Inger Porsch-Hällström; Katarzyna Smolarz; Andrew Whitehead; Södertörns högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Blue mussel; Baltic Sea; anthropogenic disturbance; pollution; sewage effluents; harbors; genetics; genomics; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Abstract : Anthropogenic environmental changes can serve as drivers for evolutionary responses in wild populations. To predict the long-term impact of anthropogenic changes on populations, it is crucial to understand the genetic effects caused by these disturbances. READ MORE

  7. 15. On the use of genomics to asses environmental risks of pharmaceuticals

    Author : Lina-Maria Gunnarsson; Göteborgs universitet; []
    Keywords : comparative pharmacology; ecotoxicology; fish; microarray; genomics; wastewater treatment;

    Abstract : Many drugs are found in the aquatic environment and are therefore a cause for concern. Low concentrations of active ingredients from human pharmaceuticals reach the environment via sewage treatment plants, mainly as a result of excretion. READ MORE
