1. 1. Ecological risk assessment of pesticide use in rice farming in the Mekong Delta , Vietnam

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Bubaraye Ohiosimuan Dirikumo; [2023]
   Keywords : Pesticides; Ecological Risk Assessment ERA ; rice farming; Mekong Delta; PRIMET Model; Exposure Toxicity Ratio ETR ; species sensitivity distribution SSD ; predicted environmental concentrations PECs ;

   Abstract : Pesticide use in rice farming is a common practice in the Mekong Delta and poses ecological risks to aquatic organisms, the environment, and human health. This study focused on the ecological risk assessment of pesticide use in rice farming using the PRIMET model as a decision support tool to evaluate the risks of pesticide exposure, ecotoxicity, and risk characterization, as well as employing the species sensitivity distribution (SSD) assessment model to calculate the potentially affected fraction (PAF) of species based on the computed predicted environmental concentrations (PECs) from PRIMET.

3. 2. Detecting Pollutants Using Vibrations : Laser Doppler Vibrometry as a Non-Invasive Soil Organism Health Monitoring Method

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Kristoffer Wilson; [2023]
   Keywords : Vibrometer; Biotremology; Imidacloprid; Ants;

   Abstract : Due to a lack of in-situ methods capable of detecting sub-lethal effects of pollutants on soil organisms, many polluted environments are not identified prior to pollution-induced changes in the soil fauna. Therefore, there is a need to develop new non-invasive methods to measure the health of soil organisms. READ MORE

4. 3. The Impact of The Neonicotinoid Pesticide Ban on Crime and Early Education in Agricultural Areas of Sweden

   University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

   Author : Sevrin Williams; [2023]
   Keywords : Neonicotinoids; Agricultural Policy; Human Capital; Crime; Education;

   Abstract : In 2013, the European Union banned the use of neonicotinoid pesticides on bee-attractive plants sown between January and June. Neonicotinoids were a popularly used pesticide because pests were not resistant against it. READ MORE

   Author : Maja Näsman; [2022]
   Keywords : Gut microbiota; polychlorinated biphenyls; organochlorine pesticides; tricarboxylic acid cycle; bile acids; LC-qTOF-MS.;

   Abstract : The gut microbiota plays a major part in maintaining the health of a human host. Countless of crucial functions in the body, including immune responses, cell signaling and energy metabolism to name a few, are conducted by the gut microbiota and its metabolites. READ MORE

6. 5. Friends with benefits? - Does gut microbiota of Spodoptera littoralis affect insecticide resistance and are there any costs of insecticide resistance development?

   University essay from SLU/Dept. of Plant Protection Biology

   Author : Sarah Heithausen; [2021]
   Keywords : insecticide resistance development; gut microbiota; gut symbiont-mediated resistance; trade-off effects; fitness costs; symbiosis; survival; life-history traits; fecundity;

   Abstract : The insect gut microbiota has many important functions for insects such as detoxification of host plant toxins. Recently there has been a growing interest on the effect of insect gut microbiota on insecticide resistance development. Insecticide resistance is a growing concern for food security and sustainable agriculture. READ MORE
