Multi-criteria method for environmental risk assessment of fuel trade within the first urban mile of Belém (Pará)

ABSTRACT This paper introduces a simple model to assess potential risk of gas stations in urban areas, which takes into account three dimensions of analysis: operational, normative, and environmental. These dimensions are distributed in eight internal and external control variables, which, in turn, are valued by qualitative and quantitative interpretation of easily available local data. The proposed model was applied to evaluate 67 gas stations located within the first urban mile of Belém, Pará, Brazil, which is characterized as the first demarcation of land granted by the Portuguese crown in the foundation of Belém, in 1616, in order to obtain the risk rating for gas station and also to produce the potential risk map for first urban area districts. Results show that most of the gas stations in the first urban mile presents high risk, whereas only a few possesses important and medium risk.摘要 本文提出一款简易评估模型，用于研判城区加油站的潜在风险，该模型纳入运营、合规、环境三大分析维度。上述三大维度拆解为八项内外部控制变量，此类变量通过对易于获取的本地数据开展定性与定量解读完成赋值。本研究所提模型被应用于评估巴西帕拉州（Pará）贝伦（Belém）市第一城市英里范围内的67座加油站——该区域为1616年葡萄牙王室为贝伦建城所划定的首批土地边界，研究旨在获取各加油站的风险评级，并绘制首批城区街区的潜在风险地图。结果显示，该第一城市英里区域内的多数加油站呈现高风险等级，仅少数加油站处于重要与中等风险等级。
