McGinley, John; Harmon O’Driscoll, Jenny; Healy, Mark G.; Ryan, Paraic C.; Mellander, Per Eric; Morrison, Liam; Callery, Oisin; Siggins, Alma (Wiley, 2022-02-22)Pesticides are widely employed as a cost-effective means of reducing the impacts of undesirable plants and animals. The aim of this paper is to develop a risk ranking of transmission of key pesticides through soil to ... -
Field assessment of coconut-based activated carbon systems for the treatment of herbicide contamination
McGinley, John; Healy, Mark G.; Scannell, Shane; Ryan, Paraic C.; Harmon O'Driscoll, Jenny; Mellander, Per-Erik; Morrison, Liam; Siggins, Alma (Elsevier, 2023-12-03)Once released into the environment, herbicides can move through soil or surface water to streams and groundwater. Filters containing adsorbent media placed in fields may be an effective solution to herbicide loss in the ... -
The impact of alternating drainage and inundation cycles on geochemistry and microbiology of intact peat cores
Healy, Mark G.; Siggins, Alma; Potito, Aaron P.; Molloy, Karen; Potito, Aaron P.; O'Leary, D.; Daly, E.; Callery, O. (Elsevier, 2022-11-02)The rewetting of degraded peatlands has been adopted as a method to address climate change. Concerns have been raised about the effects of peat inundation and drying cycles, in more extreme climate events, on the potential ... -
Pyrolysed waste materials show potential for remediation of trichloroethylene-contaminated water.
Siggins, Alma; Abram, Florence; Healy, Mark G. (Elsevier, 2019-12-17)Trichloroethylene (TCE) is an Environmental Protection Agency priority pollutant associated with cancer in humans. With numerous industrial applications and regular landfill disposal, TCE is a common landfill leachate ... -
Simultaneous adsorption and biodegradation of trichloroethylene occurs in a biochar packed column treating contaminated landfill leachate
Siggins, Alma; Thorn, Camilla; Healy, Mark G.; Abram, Florence (Elsevier, 2021-08-14)Trichloroethylene (TCE) is a human carcinogen that is commonly found in landfill leachate as a result of anthropogenic activities. Contaminated leachate plumes may be intercepted prior to reaching groundwater and treated ...
