  1. 1. Established forest firefighting techniques: A qualitative review of practices among the Swedish fire services.

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Muhammad Humza Khan; [2021]
    Keywords : Forest fires; firefighting techniques; Scientometric analysis; Effectiveness; Questionnaire; Direct attack; Indirect attack; Firelines; Prescribed burning; Aerial firefighting; Flanking; Hot-spotting; Cold trailing.; Technology and Engineering;

    Abstract : Methods and equipment used for fighting forest fires are different from the ones used in urban fires. Generally, the wildfires are intense, require more resources and tend to spread rapidly. READ MORE

  2. 2. Application of mass defect filtering and statistical analysis for non-target data mining of gas and soot data from a study testing different firefighting methods

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Danielle Ydstål; [2020]
    Keywords : ;

    Abstract : Due to the high temperatures during a fire event, a large variety of compounds are formed or released from burning materials, all of which have a varying degree of environmental effects. In an incidental fire there are several variables that are important for which and how much combustion products that are formed, including the burning material, ventilation (presence of air), and temperature.

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are a diverse group of persistent organic pollutants. PFASs have a wide area of applications such as stain repellent for paper, textile, furniture and industrial products such as aqueous film forming foams (AFFFs) used for firefighting. READ MORE

  4. 4. Uptake of per- and polyfluoroalkyl substances by plants

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Laura Gobelius; [2016]
    Keywords : phytoremediation; Arlanda Airport; PFASs; groundwater; soil; plant; AFFF; aqueous fire fighting foams;

    Abstract : The extensive use of per- and polyfluoroalkyl substances (PFASs) as surfactants in, for example textiles,cookware and aqueous firefighting foams (AFFFs) during the last decades has resulted in widespread environmental contamination. Due to the persistent and bioaccumulative characteristics of PFASs, they are ubiquitously found in the environment, wildlife and humans. READ MORE

  5. 5. Evaluation of the efficiency of treatment techniques in removing perfluoroalkyl substances from water

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sandra Lundgren; [2014]
    Keywords : PFAS; removal efficiency; MIEX®; iron III chloride; Powdered activated carbon; nanofiltration membrane; dissolved organic carbon;

    Abstract : Perfluoroalkylated substances (PFASs) are a group of synthetic compounds that have gained growing attention due to their environmental persistence, toxicity and their potential to bioaccumulate. Even though PFASs are not occurring naturally in our environment, they are globally distributed and can be found ubiquitously in air, water, soil, wildlife as well as in humans. READ MORE
