  1. 1. Determination of bio-accessible amounts of metal trace elements in baby food using In vitro artificial digestion

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Marcus Andersson; [2022]
    Keywords : Food; toxic metals; children; bio-accumulation; artificial digestion; ICP-MS;

    Abstract : Prefabricated baby food is under strict EU legislation by Commission Regulation (EC) 1881/2006 Setting maximum levels for certain contaminants in foodstuffs regarding the maximum allowed content of potentially harmful elements. For potentially toxic trace elements the regulated maximum content is regulated for lead, cadmium, mercury, inorganic tin, inorganic arsenic, cesium, copper and manganese. READ MORE

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Nathalie Pantzare; [2021]
    Keywords : biochar; contaminated sediment; remediation; thin-layer capping;

    Abstract : Coastal areas around the world have been recognized as largely impacted by anthropogenic activities resulting in pollution of marine sediments. In Sweden, surveys conducted along the coastline of the Bothnian Bay have identified a total area of about 29 km2 as fiber rich sediments. READ MORE

  4. 3. A hydrochemical investigation and socioeconomic assessment in Rio Zapomeca river basin focusing on arsenic contamination

    University essay from Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet; Lunds universitet/Riskhantering (CI)

    Author : Axel Hagström; Anton Rydstedt; [2015]
    Keywords : geology; groundwater; drinking water; water contamination; water treatment; value of statistical life; cost-benefit-analysis; Resistivity; Arsenic; Risk; Technology and Engineering;

    Abstract : The awareness of problems concerning arsenic contaminated drinking water sources has during recent years increased. WHO (World Health Organization) decided in 1993 to lower the recommended limit of arsenic in drinking water from 50 μg/l to 10 μg/l, mainly due to observations of its carcinogenicity. READ MORE

  5. 4. Quality Assessment of sludge from Glen Valley WWTP and its potential as fertilizer

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Ellen Åberg; Johanna Norup; [2015]
    Keywords : Technology and Engineering;

    Abstract : The use of sludge as fertilizers contributes to the recycling of nutrients to the environment due to its origin from wastewater and therefore relatively high content of nutrients and organic matter. However, wastewater does also contain hazardous compounds like heavy metals and micropollutants which eventually are separated to the sludge during the treatment processes at the wastewater treatment plant.
