Ornithogenic soil is derived from the deposition of fecal matter various species birds and a major source nutrient input in Antarctic marine ecosystem. A significant proportion microbiota ornithogenic collected an Adélie penguin colony eastern Antarctica (Vestfold Hills ice-free zone) consisted gram-negative, coccoid bacteria identified on basis their phospholipid ester-linked fatty acid lipid class profiles as Psychrobacter strains. Phenotypic, genotypic, 16S ribosomal DNA phylogenetic...

Adverse respiratory effects of particulate air pollution have been identified by epidemiological studies. We aimed to examine the health ambient from wood burning on school-age students in Christchurch, New Zealand, and explore utility urine exhaled breath condensate biomarkers exposure this population.A panel study 93 male (26 with asthma) living boarding house a metropolitan school was undertaken winter 2004. Indoor outdoor data continuously monitored. Longitudinal assessment lung function...
Accounting for sustainability is approaching its (metaphoric) teenage years – keen to assert independence, yet still reliant on the security of background disciplines and not quite mature enough make own judgements. One example Sustainability Assessment Model, a full-cost-accounting tool that monetizes externalities. This paper examines application in case studies where it faced issues over assessment boundaries, data limitations, stakeholder engagement. There much development needed,...
Wheat ( L.) grain is a contributing source of dietary Cd in New Zealand, but despite this, there dearth information on concentrations wheat and the factors that affect uptake. We measured 12 cultivars grown field sites across Zealand also assessed soil, plant, crop have been reported to found was wide range (0.004 0.205 mg kg fresh weight [FW]). The overall mean concentration (0.066 FW) below maximum limit (ML) 0.1 FW. Only 7% samples seven exceeded ML. There were significant < 0.05)...
The widespread use of silver nanoparticles (AgNPs) as a bactericide will ultimately result in their increased concentration soils. We sought to determine the likely mobility, toxicity, and plant uptake Ag applied soil either AgNPs or + . measured solubility, both an immature Pallic soil, Templeton loamy silt (pH = 5.1), granular loam 6.0). sorption by test soils was significantly greater than , moieties were more strongly sorbed at lower concentrations higher pH values. Between 4 8,...
Abstract Investigating the toxicity of acid mine drainage (AMD) on benthic communities in receiving waters can be highly challenging because difficulty unraveling effects acidity, dissolved metals, and precipitates. Furthermore, survival different species may vary depending any natural adaptation they have acquired to low pH, or sedimentation. We investigated effect pHs AMD a common New Zealand leptophlebiid mayfly ( Deleatidium spp.) 96‐h laboratory trials. Our results indicate that primary...
Silver nanoparticles (AgNPs) from industrial use, discharged via the land application of sewage sludge, are interacting with soil biota, including earthworms. In affected organisms, excessive production reactive oxygen species can result in lipid peroxidation, shifting balance between oxidants and antioxidants to cause oxidative stress. We determined selected lower-tier biomarkers such as antioxidant responses peroxidation Aporrectodea caliginosa earthworms exposed soils spiked AgNPs or...
Abstract With increasing urbanisation, there is a growing disconnect between soil, food, and people, centred around those relying on Western food production models. This ‘wicked’ problem challenging sustainable soil use insecurity. Knowledge of soils through scientific studies alone are unable to address this problem, we need extend the boundaries science for real progress be made. We present conceptual framework understanding reciprocal connections people in local systems Aotearoa New...
Repeated applications of Cd-rich phosphate fertilizers have resulted in elevated concentrations this toxic element some New Zealand soils. Exceedance the food safety standard for Cd (0.1 mg kg fresh weight) has been reported potato ( L.). Composts may efficiently sorb soil and therefore reduce its phytoavailability, leading to reduced uptake by plants. We aimed determine potential various composts, shredded corn stover, lime at two different rates transfer from a (containing 1.45 Cd) (var....
