  • Cadmium accumulation in three contrasting New Zealand soils with the same phosphate fertilizer history

    Salmanzadeh, Mahdiyeh; Balks, Megan R.; Hartland, Adam; Schipper, Louis A. (Elsevier, 2016)
    Cadmium (Cd) concentration in New Zealand (NZ) agricultural soils has increased due to phosphate fertilizer application, but it is not clear whether soils with different properties accumulate Cd at similar rates for given ...
  • Chaos and irregularity in karst percolation

    Mariethoz, Gregoire; Baker, Andy; Sivakumar, Bellie; Hartland, Adam; Graham, Peter (American Geophysical Union, 2012)
    This paper focuses on analyzing chaos in cave percolation water drip rates, which has implications for flow routing in fractured media and on the use of speleothems for paleoclimate reconstructions. It has been shown that ...
  • The effect of irrigation on cadmium, uranium, and phosphorus contents in agricultural soils

    Salmanzadeh, Mahdiyeh; Schipper, Louis A.; Balks, Megan R.; Hartland, Adam; Mudge, Paul Lawrence; Littler, Ray A. (Elsevier, 2017)
    Cadmium (Cd) is a toxic metal which has accumulated in New Zealand agricultural soils due to phosphate fertilizer application. Understanding the contribution of plant uptake or leaching of Cd to observed Cd losses from ...
  • The environmental significance of natural nanoparticles

    Hartland, Adam; Lead, Jamie R.; Slaveykova, Vera I.; O’Carroll, Denis; Valsami-Jones, Eugenia (Nature Publishing Group, 2013)
    Natural water-borne nanoparticles are ubiquitous. Their very small size, ranging from 1 to 100 nanometers means they are both highly mobile and chemically reactive. Nanoparticles are central in buffering environmental ...
  • Isotope Tracing of Long-Term Cadmium Fluxes in an Agricultural Soil

    Salmanzadeh, Mahdiyeh; Hartland, Adam; Stirling, Claudine H.; Balks, Megan R.; Schipper, Louis A.; Joshi, Chaitanya; George, Ejin (American Chemical Society, 2017)
    Globally widespread phosphate fertilizer applications have resulted in long-term increases in the concentration of cadmium (Cd) in soils. The accumulation of this biotoxic, and bioaccumulative metal presents problems for ...
