An assessment of potential pesticide transmission, considering the combined impact of soil texture and pesticide properties: A meta-analysis
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 ... -
Bioaccumulation of metals in ryegrass (Lolium perenne L.) following the application of lime stabilised, thermally dried and anaerobically digested sewage sludge.
Healy, Mark G.; Ryan, Paraic C.; Fenton, Owen; Peyton, Dara P.; Morrison, Liam (Elsevier ScienceDirect, 2016-05-09)The uptake and accumulation of metals in plants is a potential pathway for the transfer of environmental contaminants in the food chain, and poses potential health and environmental risks. In light of increased population ... -
