  • Achieving drinking water compliance levels for metaldehyde with an acclimated sand bioreactor 
    Rolph, Catherine A.; Jefferson, Bruce; Brookes, Adam; Hassard, Francis; Villa, Raffaella (Elsevier, 2020-07-06)
    Metaldehyde removal was delivered to below the 0.1 µg L-1 regulatory concentration in a laboratory scale continuous upflow fluidised sand bioreactor that had undergone acclimation through selective enrichment for metaldehyde ...
  • The challenges, uncertainties and opportunities of bioaerosol dispersion modelling from open composting facilities 
    Williams, Ben; Hayes, Enda; Nasir, Zaheer A.; Rolph, Catherine A.; Jackson, Simon; Khera, Shagun; Bennett, Alan; Gladding, Toni; Drew, Gillian H.; Tyrrel, Sean F. (WIT Press, 2017-08-06)
    Bioaerosols are ubiquitous organic particles that comprise viruses, bacteria and coarser fractions of organic matter. Known to adversely affect human health, the impact of bioaerosols on a population often manifests as ...
  • Concentration and composition of bioaerosol emissions from intensive farms: pig and poultry livestock 
    Gladding, T. L.; Rolph, Catherine A.; Gwyther, C. L.; Kinnersley, R.; Walsh, K.; Tyrrel, Sean F. (Elsevier, 2020-07-14)
    Intensive farming is widespread throughout the UK and yet the health effects of bioaerosols which may be generated by these sites are currently not well researched. A scoping study was established to measure bioaerosols ...
  • A controlled study on the characterisation of bioaerosols emissions from compost 
    Nasir, Zaheer A.; Rolph, Catherine A.; Collins, Samuel; Stevenson, David; Gladding, Toni L.; Hayes, Enda; Williams, Ben; Khera, Shagun; Jackson, Simon; Bennett, Allan; Parks, Simon; Kinnersley, Robert P.; Walsh, Kerry; Pollard, Simon J. T.; Drew, Gillian; Garcia Alcega, Sonia; Coulon, Frederic; Tyrrel, Sean (2018-09-28)
    Bioaerosol emissions arising from biowaste treatment are an issue of public concern. To better characterise the bioaerosols, and to assess a range of measurement methods, we aerosolised green waste compost under controlled ...
  • From full-scale biofilters to bioreactors: Engineering biological metaldehyde removal 
    Rolph, Catherine A.; Villa, Raffaella; Jefferson, Bruce; Brookes, Adam; Choya, Andoni; Iceton, Gregg; Hassard, Francis (Elsevier, 2019-05-21)
    Polar, low molecular weight pesticides such as metaldehyde are challenging and costly to remove from drinking water using conventional treatment methods. Although biological treatments can be effective at treating ...
  • Metaldehyde removal from drinking water by adsorption onto filtration media: mechanisms and optimisation 
    Rolph, Catherine A.; Jefferson, Bruce; Hassard, Francis; Villa, Raffaella (2018-08-10)
    Trace micropollutants should be removed during drinking water production without increasing the disinfection-by-product formation potential or energy demand of the treatment process. We demonstrate the efficacy of different ...
  • Scoping studies to establish the capability and utility of a real-time bioaerosol sensor to characterise emissions from environmental sources 
    Nasir, Zaheer A.; Hayes, Enda; Williams, Ben; Gladding, Toni; Rolph, Catherine A.; Khera, Shagun; Jackson, Simon; Bennett, Allan; Collins, Samuel; Parks, Simon; Attwood, Alexis; Kinnersley, Robert P.; Walsh, Kerry; Garcia Alcega, Sonia; Pollard, Simon J. T.; Drew, Gill; Coulon, Frederic; Tyrrel, Sean (Elsevier, 2018-08-09)
    A novel dual excitation wavelength based bioaerosol sensor with multiple fluorescence bands called Spectral Intensity Bioaerosol Sensor (SIBS) has been assessed across five contrasting outdoor environments. The mean ...
  • Sources of airborne endotoxins in ambient air and exposure of nearby communities - a review 
    Rolph, Catherine A.; Gwyther, Ceri L.; Tyrrel, Sean F.; Nasir, Zaheer A.; Drew, Gillian H.; Jackson, Simon K.; Khera, Shagun; Hayes, Enda T.; Williams, Ben; Bennett, Allan; Collins, Samuel; Walsh, Kerry; Kinnersley, Rob; Gladding, Toni L. (MDPI, 2018-09-26)
    Endotoxin is a bioaerosol component that is known to cause respiratory effects in exposed populations. To date, most research focused on occupational exposure, whilst much less is known about the impact of emissions from ...
  • Towards improved bioaerosol model validation and verification 
    Williams, Ben; Hayes, Enda; Nasir, Zaheer A.; Rolph, Catherine A.; Jackson, Simon; Khera, Shagun; Bennett, Alan; Gladding, Toni; Drew, Gillian; Longhurst, James; Tyrrel, Sean (WIT Press, 2018-10-23)
    Bioaerosols, comprised of bacteria, fungi and viruses are ubiquitous in ambient air. Known to adversely affect human health, the impact of bioaerosols on a population often manifests as outbreaks of illnesses such as ...
