  1. 1. Preliminary experimental study on the affect of water of the hydrogen reduced hematite pellet

    Master-uppsats, KTH/Materialvetenskap

    Författare :Henrik Welander; [2021]
    Nyckelord :;

    Sammanfattning : Global warming is one of the most important challenges that we are facing today. Since carbon dioxide (CO2) is by far our most common green house gas pollutant,  most large corporations need to reconsider how their production is performed to keep the global warming below 2 ◦C.

  3. 2. Utvärdering av faktorer för optimering av biologisk in situ-sanering av bensinförorenad mark

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Niklas Johansson; [2021]
    Nyckelord :in situ; remediation; enhanced biodegradation; BTEX; benzene; toluene; ethylbenzene; xylenes; petrol; filling station; soil pollution; groundwater; oxidiser; parameter; environment; in situ; sanering; förhöjd biologisk nedbrytning; BTEX; bensen; toluen; etylbensen; xyleber; bensin; drivmedelsanläggning; bensinstation; markförorening; grundvatten; oxidationsmedel; parameter; miljö;

    Sammanfattning : En av de vanligaste föroreningarna i mark och grundvatten är aromatiska kolvä- ten såsom bensen, toluen, etylbensen och xylener. Dessa härstammar från ex. ben- sin och har läckt ut till omgivande miljö från drivmedelsanläggningar. LÄS MER

  4. 3. A Lead (Pb) Mass-Balance Budget for a Dry Periglacial Catchment in West Greenland : Discussing the fate of pollutant Pb

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Andreas Nylund; [2020]
    Nyckelord :Lead mass-balance budget; Dry periglacial landscape; Whole catchment; Pollution; Climate change;

    Sammanfattning : Lead (Pb), occurs both naturally and as a pollutant in Arctic landscape systems. The ongoing climate change, especially pronounced in the Arctic, changes the premises for Pb transport and mobility. LÄS MER

  5. 4. Investigation of the Metal Content in Cress Seedlings fed with increased Concentration of Lead & Iron Solutions

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Nikita Burton; [2020]
    Nyckelord :Cress; iron; lead; metals; acidified digestion; MP-AES; ICP-MS;

    Sammanfattning : Metals are essential nutrients for plant health, but not all metals are necessary and can sometimes be harmful towards plants depending on factors such as species, elemental composition in the soil and concentration of a metal. Iron (Fe), which is one of the most abundant metals in the earth’s crust is also one the most important nutrients for plant growth, as it is responsible for metabolism. LÄS MER

  7. 5. Indoor and Outdoor Measurements of Particulate Matter with the Low-Cost Optical Sensor OPC-N3

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Ellen Grace Soroka; [2020]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : This paper evaluates the low-cost optical sensor OPC-N3 from Alphasense as a suitable scientific instrument for measuring particulate matter levels in air, both outdoors and in- doors. The time-keeping and data-retrieval was additionally improved by connecting the OPC-N3 to an Arduino microcontroller equipped with a real-time clock (RTC) module and an external SD card. LÄS MER
