• Assessing acid rain and climate effects on the temporal variation of dissolved organic matter in the unsaturated zone of a karstic system from southern China 

  Liao, Jin; Hu, Chaoyong; Wang, Miao; Li, Xiuli; Ruan, Jiaoyang; Zhu, Ying; Fairchild, Ian J.; Hartland, Adam (Elsevier, 2018)

  Acid rain has the potential to significantly impact the quantity and quality of dissolved organic matter (DOM) leached from soil to groundwater. Yet, to date, the effects of acid rain have not been investigated in karstic ...

• 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 ...

• Biogeochemical Characterisation of an Alum Dosed Stream: Implications for Phosphate Cycling in Lake Rotoehu 

  Eager, Christopher Andrews (The University of Waikato, 2017)

  Lakes are highly valued freshwater ecosystems which provide many goods and services upon which humans are reliant. Eutrophication of waterways, driven by the over-enrichment of nutrients such as phosphorus and nitrogen, ...

  

• Cadmium accumulation in agricultural soils 

  Salmanzadeh, Mahdiyeh (The University of Waikato, 2017)

  Cadmium (Cd) has accumulated in New Zealand (NZ) soils as a result of phosphate fertiliser application. Cadmium is a biotoxic heavy metal and can be adsorbed by soil and enter the human food chain. Three objectives were ...

  

• The Fate and Effects of Contaminants in Estuarine Environments 

  Huteau, Julien (University of Waikato, 2017)

  Estuaries are sensitive environments regarding their response to anthropogenic events. The accumulation of toxic trace elements, such as Cd and Pb, has detrimental consequences on benthic community composition and function ...

  

• Temporal variability in the water quality of a deep temperate oligotrophic lake 

  Kpodonu, Alfred Theodore Nutefe Kwasi (University of Waikato, 2016)

  Lakes change over time in response to climate and catchment disturbance, even in the absence of anthropogenic stressors. This temporal change may impact the setting of reference conditions for lakes. Many sources of ...

  

• The Effects of Contaminated Rena Sediments on Juvenile Paua (Haliotis iris) 

  McSweeney, Caleb S. (University of Waikato, 2015)

  The grounding of the MV Rena on Otaiti resulted in the release of heavy fuel oil and container debris contaminants into the surrounding environments including the rocky shores of the adjacent Mōtītī Island. This is the ...
