摘要

发展中国家城市化和工业化的步伐正在迅速加快。不幸的是,监管机构和私营部门对危害的控制并不总是与之同步。这项工作确定了化学工业的应急准备水平,并利用最坏情况释放情景评估了危害的空间分布。因此,我们确定了潜在暴露的城市社区,并评估了危害的社会认知。本研究以墨西哥圣路易斯波托西工业区为例,描述了风险情景。当应急准备的不足加上社会对潜在危险社区的不良认识时,就会认识到重大关切的干预区。可燃性化学品的最坏情况半径为425m ~ 733m。可能受到接触的社区对化学品风险的认识有限,也没有接受过应急培训。靠近工业区会影响社区更好地认识危害。然而,远离工业区的社区对可燃化学品的最坏情况的准备程度较低,并且由于缺乏风险认知,他们的脆弱性更大。

Differences in the risk profiles and risk perception of flammable liquid hazards in San Luis Potosi, Mexico

The pace of urbanization and industrialization in developing countries is rapidly increasing. Unfortunately, regulatory and private-sector control of hazards has not always kept pace. This work identifies the level of emergency preparedness in chemical industries and evaluates the spatial distribution of hazards using a worst-case release scenario. Consequently, we identified potentially exposed urban communities and evaluated the social perception of a hazard. This research characterizes risk scenarios in a case study of the industrial area in San Luis Potosi, Mexico. Intervention zones of major concern are recognized when deficiencies in emergency preparedness join a poor social perception of hazards in communities that are potentially exposed. The worst-case scenario radii of flammable chemicals range from 425 m to 733 m. Potentially exposed communities have a limited perception of chemical risk and no training in emergency response. Proximity to an industrial area influences communities towards a better recognition of hazards. However, communities far from the industrial area have higher exposure to low preparedness worst-case scenarios for flammable chemicals and have a larger level of vulnerability because of their lack of risk perception.
