Environmental liabilities have become one of the most important problems at environmental level, especially those located in urban areas. Within the area of the Río de la Plata coastal plain, industrial waste abandoned by an ancient sulfuric acid industry in a sector of the petrochemical center constitutes an environmental liability composed mainly of fragments of native sulfur. The aim of this work is to evaluate, from laboratory tests, the generation of sulfate acid drainage in environmental liabilities associated with the ancient sulfuric acid industry in order to identify the waste spatial distribution and to determine the impacts that they impart on the quality of the soil and groundwater. The results obtained show that the native sulfur scattered in the environmental liability associated with the ancient sulfuric acid industry constitutes a potential source of sulfated acid drainage that locally affects the soil, groundwater, and underground structures of the industrial center, and also small adjacent ecosystems. The interaction between native sulfur and the rainwater causes the oxidation of the native sulfur releasing protons and sulfates, which reach the groundwater through the infiltration water process, generating the acidification of the environment. The results provide useful draft for the management of environmental liabilities, and also the monitoring data obtained could assist in prioritization of remediation options, which constitute a problem of relevance and whose regulations for management and mitigation are still a controversial issue.

在环境层面，尤其是在城市地区，环境责任已成为最重要的问题之一。在Ríode la Plata沿海平原地区，石化中心所在区域的古代硫酸工业丢弃的工业废物构成环境责任，主要由天然硫的碎片组成。这项工作的目的是通过实验室测试评估与古代硫酸工业相关的环境责任中硫酸盐排放的产生，以便确定废物的空间分布并确定它们对废物质量的影响。土壤和地下水。获得的结果表明，散布在与古代硫酸工业相关的环境责任中的天然硫构成了硫酸化酸排出的潜在来源，其局部影响着工业中心的土壤，地下水和地下结构，以及附近的小型生态系统。天然硫与雨水之间的相互作用导致天然硫的氧化，释放出质子和硫酸盐，这些质子和硫酸盐通过渗透水过程到达地下水，从而导致环境酸化。结果为管理环境负债提供了有用的草案，并且所获得的监测数据可以帮助确定补救方案的优先次序，
