    selected and sampled within each river on four separate occasions: 20-22 July, 10 August, 20-22 September, and 21-22 November 2011. The values were compared to measured precipitation rates: 27.5mm, 0mm, 222mm and 0mm respectively. Radiocaesium contamination concentrations along with various other water quality parameters were assessed. It was found that the rate of discharge strongly correlates with the amount of radiocaesium concentrations found within the samples. Both dissolved and…

    An important chemical property of soil that can affect herbicide persistence is pH. Soil composition is a physical factor determined by the relative amounts of sand, silt, and clay in the soil (the soil texture), as well as by the organic-matter content. The types and abundance of soil microorganisms present in the soil make up the microbial aspects of the soil environment. Generally, soils high in clay, organic matter, or both have a greater potential for herbicide…

    population, must come into contact with the environmental medium (Simon, 2014). The environmental mediums are soil, water, air, and biota. The concentration of the pesticide present must be determined in order to calculate a dose. Also, with each individual medium there will be a level of variability and uncertainty that must be considered. Contamination concentrations in the soil will be highly variable. This is due to the application of the pesticide. The areas directly where the…
