2019 年 3 月 17 日至 20 日，洲际码头公司（ITC，美国德克萨斯州拉波特鹿园）发生火灾，导致化学污染物大量释放到环境中，包括休斯顿航道的地表水。描述这些释放的空间和时间趋势以及潜在的人类健康风险。在 433 种有可用数据的物质中，选择了 7 种进行分析：苯、甲苯、乙苯、二甲苯、油和油脂、悬浮固体和总石油烃。对空间和时间浓度趋势进行了表征，并计算了危害商和癌症风险，以估计这些污染物对人类健康影响的潜力。时间分析显示事件发生后水中立即存在这些化学污染物；它们的浓度在 4 周内大幅消散。污染物的空间分布表明，ITC 周围 1 公里范围内的水道浓度最高。最大的潜在人类健康风险源于苯的存在。事故发生附近，多种有害污染物的浓度出现了短期但大幅的飙升，浓度在一个月内恢复到明显的基线水平，这可能是由于挥发、稀释和降解的综合作用。
The fire at the Intercontinental Terminals Company (ITC, Deer Park, La Porte, TX, USA) from March 17-20, 2019 resulted in substantial releases of chemical contaminants to the environment, including the surface waters of the Houston Ship Channel. To characterize spatial and temporal trends, as well as potential human health risks, from these releases. Out of 433 substances with available data, seven were selected for analysis: benzene, toluene, ethylbenzene, xylenes, oil & grease, suspended solids, and total petroleum hydrocarbons. Spatial and temporal concentration trends were characterized, and hazard quotients and cancer risks were calculated to estimate the potential for human health impacts from these contaminants. Temporal analysis showed presence of these chemical contaminants in water immediately after the event; their concentrations dissipated substantially within 4 weeks. The spatial distribution of contaminants indicated the highest concentrations in the waterways within about 1km of the ITC. The greatest potential human health risks stemmed from presence of benzene. A short-term but substantial spike in the concentrations of a number of hazardous contaminants occurred near the incident, with concentrations returning to apparent baseline levels within one month likely due to a combination of volatization, dilution and degradation.
