1. 1. TOXICITY DRIVERS IN CHEMICAL MIXTURES FROM THE SWEDISH WEST COAST – EFFECTS ON PELAGIC COMMUNITIES

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Helena Hartmann; [2023-06-26]
   Keywords : ;

   Abstract : Human society benefits from a range of ecosystem services provided by the oceans, such as oxygen production, carbon storage, and fishing. However, these services are relying on the ecosystem’s functional and structural integrity, which are correlated to its biodiversity. READ MORE

3. 2. ASSESSING MICROBIAL COMMUNITY RESPONSES IN A CHEMICALLY STRESSED FRESHWATER ECOSYSTEM USING ENVIRONMENTAL DNA

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Nicolai Laufer; [2023-06-21]
   Keywords : ;

   Abstract : Microbial communities represent the fundamental cornerstones of riverine ecosystems because they are involved in numerous processes which mediate ecosystem services. However, riverine ecosystems are currently massively altered by a variety of anthropogenic activities which includes changes in landuse and chemical pollution. READ MORE

4. 3. 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.

5. 4. Temporal trends of 4-Hydroxychlorothalonil in maternal serum samples, 1997-2015

   University essay from Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

   Author : Elin Wällstedt; [2023]
   Keywords : Biomonitoring; human exposure effects; environmental exposure; fungicide; pregnancy; pregnant women; chlorothalonil; CHT; 4-hydroxy-chlorothalonil; 4-OH-CHT; Earth and Environmental Sciences;

   Abstract : Agricultural fungicides are extensively used for infestation control, resulting in residues of these compounds in food. Human exposure to environmental contaminants might occur via different routes, such as inhalation, skin contact, or ingestion. Exposure to several pesticides has been associated with adverse human health outcomes. READ MORE

6. 5. Comparison of the lead-leakage in Pb-Sn hybrid perovskite solar cells and Pb-based perovskite solar cells

   University essay from Linköpings universitet/Tema Miljöförändring

   Author : Chao Cui; [2023]
   Keywords : perovskite; solar cell; Pb-Sn hybrid; lead leakage;

   Abstract : Perovskite solar cells exhibit outstanding device performance and photovoltaic potential in recent ten years. However, the photoactive layer of the majority of perovskite solar cells with outstanding efficiency currently contains toxic lead. READ MORE
