Abstract—The contamination of toxic in agricultural food
and environment are the concerned issue in Thailand because it
could damage the agricultural land and health of people in the
long time and it also take many time to recover. This study were
studied the environmental impact of organic lettuce (Grand
rapids) compared with the conventional lettuce. The study
consider 8 impact categories: 1) Climate change, 2) Human
toxicity, 3) Terrestrial ecotoxicity, 4) Freshwater ecotoxicity, 5)
Water depletion, 6) Fossil depletion, 7) Freshwater
eutrophication and 8) Marine eutrophication. The scope
considers the material input production, transportation and
emission from the farm .The result of this study shown that
organic lettuce were lower impact than conventional lettuce in
all impact categories especially the three toxicity issue.
Therefore, the organic lettuce could be the solution way to
mitigation the environmental impact from the conventional
lettuce in Thailand.
Index Terms—Life cycle assessment, organic lettuce, Human toxicity, organic farming.
