Global Warming and Toxicity Impacts: Peanuts in Georgia, USA Using Life Cycle Assessment

Fertilizers and pesticides have been widely used in agriculture production, causing polluted soil, water, atmosphere. This study aims to quantify air emissions from fertilizers applied for peanut production Georgia during selected years (1991, 1999, 2004, 2013, 2018). Specifically, the oral dermal potential impacts pesticide global warming (GWP) impact were investigated. followed ISO 14040 series standards life cycle assessment (LCA) methodology assess six active ingredients (AIs) (2,4-DB, Bentazon, Chlorothalonil, Ethalfluralin, Paraquat, Pendimethalin) one greenhouse gas (nitrous oxide N2O). Their physical chemical characteristics temporal scales greatly influenced toxicity impacts. According low values obtained Henry’s law (KH) vapor pressure (VP), 2,4-dichlorophenoxy butanoic (DB), Pendimethalin, Chlorothalonil a higher on continental scale. The effect factor (EF) exposure was 2,4-DB, Pendimethalin than exposure, according relatively lethal dose (LD50) while EF of Ethalfluralin same their similar LD50.
