  2. 1. Environmental Pesticide Exposure and Neurobehavioral Effects among Children of Nicaraguan Agricultural Workers

    Author : Teresa Rodríguez; Catharina Wesseling; Ingvar Lundberg; Berna van Wendel de Joode; Ingvar Bergdahl; Uppsala universitet; []
    Keywords : pesticides; organophosphates; pyrethroids; children; cognitive function; behavioral outcomes; neurodevelopment; Occupational and Environmental Medicine; Arbets- och miljömedicin; Epidemiologi; Epidemiology;

    Abstract : Background: Children exposed to pesticides are susceptible for neurodevelopmental disruption. Data from developing countries are scarce.Aim: Assessing long-term and recent pesticide exposure in Nicaraguan children in relation to parental pesticide use and examining potential associated neurobehavioral effects.

  4. 2. Assessing human exposure to phthalates, alternative plasticizers and organophosphate esters

    Author : Tuong Thuy Bui; Ian T. Cousins; Andrew Sweetman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human exposure; phthalates; organophosphates; plasticizers; flame retardants; modelling; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Phthalate esters (PEs) and organophosphate esters (OPEs) are common indoor pollutants frequently detected in environmental (dust, air), personal (hand wipes, diet) and human matrices (urine, serum etc.). READ MORE

  5. 3. Developmental neurotoxicity of persistent and non-persistent pollutants : Behavioral and neurochemical assessments of a perfluorinated compound, pesticides and interaction effects

    Author : Iwa Lee; Henrik Viberg; Per Eriksson; William Mundy; Uppsala universitet; []
    Keywords : Brain; Neonatal; Mixtures; Cholinergic system; Organochlorines; Pyrethroids; Organophosphates; Carbamates; Insecticides; PFCs; PFAAs; PFHxS; Endosulfan; Cypermethrin; Chlorpyrifos; Carbaryl; Biology with specialization in Environmental Toxicology; Biologi med inriktning mot miljötoxikologi;

    Abstract : The focus of this thesis was to investigate developmental neurotoxic effects of different persistent and non-persistent environmental pollutants, alone or in binary mixtures, when exposure occurs during a critical period of brain development, in mice. The compounds investigated included a perfluorinated compound, perfluorohexane sulphonate (PFHxS), and four different pesticides, endosulfan, cypermethrin, chlorpyrifos and carbaryl. READ MORE

  6. 4. Organophosphates and phthalates in air and dust from indoor environments : Method development and applied measurements

    Author : Caroline Bergh; Conny Östman; Peter Haglund; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organophosphate esters; phthalate esters; air; dust; sampling; method development; GC MS; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : Organophosphate and phthalate esters are polymer additives that are frequently found in air and dust in indoor environments. This thesis describes the development and application of air sampling and selective mass spectrometric (MS) determination of these two compound groups. READ MORE

  7. 5. Surface reactions on mineral particles controlling the hydrolysis of glucose phosphates

    Author : Rickard Olsson; Per Persson; Reiner Giesler; Dean L. Hesterberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry; Kemi;

    Abstract : Phosphorus (P) is an essential nutrient. A significant amount of soil P may be in the form of organophosphates. Due to the size of these compounds, hydrolysis is often required before P can be assimilated by organisms. Hydrolysis may be mediated by mineral surfaces, or catalyzed by extra cellular enzymes.
