Tobacco is the most widespread non-food crop in the world. In Brazil, tobacco cultivation is one of the main commodities of the southern region. However, its production is associated with environmental impacts and risks to human health, which have yet to be quantified. This paper uses midpoint and endpoint life cycle assessment (LCA) to analyze the potential environmental damage and human health risk associated with agricultural production of conventional Virginia (CV), organic Virginia (OV), and Burley (BU) tobacco varieties. Organic tobacco production substitutes synthetic fertilizers and pesticides with organic compounds in the cropping stage. The results show that for one ton of dried tobacco, BU, CV, and OV emit 1,610, 1,426, and 1091 kg CO₂ eq, respectively. For organic production, greater impacts are linked to the land use (LU) impact category. The endpoint results showed that OV production resulted in a higher potential for human and environmental damage than BU and CV. The drying of green OV and CV tobacco requires the burning of firewood, which emits high levels of particulate matter and is associated with human health (HH) damage. Overall, the HH damage category accounts for 68%, 82%, and 78% of the total score points associated with the production of BU, CV, and OV.

烟草是世界上最广泛的非粮食作物。在巴西，烟草种植是南部地区的主要商品之一。但是，其生产与环境影响和人类健康风险相关，尚待量化。本文使用中点和终点生命周期评估（LCA）分析与常规弗吉尼亚（CV），有机弗吉尼亚（OV）和白肋烟（BU）烟草品种的农业生产相关的潜在环境损害和人类健康风险。在种植阶段，有机烟草生产用有机化合物替代了合成肥料和农药。结果表明，对于一吨干烟草，BU，CV和OV分别排放1,610、1,426和1091 kg CO ₂eq分别。对于有机生产，更大的影响与土地利用（LU）影响类别相关。最终结果表明，与BU和CV相比，OV产生的人为和环境破坏潜力更高。绿色OV和CV烟草的干燥需要燃烧木柴，木柴散发出大量的颗粒物，并与人体健康（HH）损害相关。总体而言，HH损坏类别分别占与BU，CV和OV产生相关的总得分的68％，82％和78％。
