  1. 1. Mercury and methyl mercury release in soil and water - their relationship with different properties in Skogaryd

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Linnéa Johansson; [2020-07-08]
    Keywords : mercury; methylmercury; demethylation; pH; dissolved oxygen and total organic content;

    Abstract : In Skogaryd research site, water samples were taken and analysed for total mercury (Hgtot) andmethylmercury (MeHg) concentration along with the pH, dissolved oxygen (DO) and total organiccontent (TOC). This to give the condition of the site before the forest is clear-cute and a part of theland rewetted to a wetland. READ MORE

  2. 2. Development and Testing of a Hydro-Chemical River MixingModel to Investigate Sources of Carbon and Mercury in the Mackenzie River Basin, Canada

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Torbjörn-Johannes Erikson; [2020]
    Keywords : mercury; Hg; POC; DOC; Mackenzie River; kvicksilver; Hg; DOC; POC; Mackenziefloden;

    Abstract : Mercury, Hg, is found in Arctic biota in alarming quantity, posing a potential health risk for the local population. It is believed that the large Arctic rivers contribute to this. The Mackenzie River annually transports approximately 325 km3 water to the Arctic Ocean, which is ca 10% of the freshwater received. READ MORE

  3. 3. Implementation of Swedish Risk Assessment Guidelines in Kodaikanal, India : A Study of Mercury Contamination in an Area Near a Former Thermometer Factory

    University essay from Uppsala universitet/Institutionen för geovetenskaper; Uppsala universitet/Institutionen för geovetenskaper

    Author : Anna Lindholm; Carin Hayer; [2020]
    Keywords : Mercury contamination; Thermometer Factory Kodaikanal; Risk Assessment in Sweden; Risk Assessment in India; Environmental Legislation; Remediation Methods; Sustainable Development Goals;

    Abstract : The aim of the project was to make a detailed risk assessment using Swedish guidelines for a factory site in Kodaikanal, South India, and a nearby village called Vellagavi. The study areas were chosen due to previous records of mercury contamination on the factory site and a possible spread to Vellagavi. READ MORE

  5. 5. Theoretical design of an XRF system for environmental measurements of Mercury in fiber banks

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Runpeng Yu; [2020]
    Keywords : XRF detection system; MCNP modelling; Mercury; Fiber bank;

    Abstract : This thesis demonstrates the advantages of using the Energy-dispersive X-ray fluorescence (ED-XRF) system to quantify the mercury content in fiber banks at first. The Monte Carlo N-Particle (MCNP) code was then used to simulate the XRF system model with suitable parameters such as the input X-ray energy level, the detector material, and the environmental factor (water depth).
