Toxic_Release_Inventory_2018

The 2018 TRI preliminary dataset consists of TRI data for 2018. Users should note that while these preliminary data have undergone the basic data quality checks included in the online TRI reporting software, they have not undergone the complete TRI data quality process. In addition, EPA does not aggregate or summarize these data, or offer any analysis or interpretation of them. You can use the TRI preliminary dataset to: Identify how many TRI facilities operate in a certain geographic area (for example, a ZIP code); Identify which chemicals are being managed by TRI facilities and in what quantities; and Find out if a particular facility initiated any pollution prevention activities in the most recent calendar year. The agency will update the dataset several times in August and September based on information from facilities. EPA plans to publish the complete, quality-checked 2018 dataset in October 2019, followed by the 2018 TRI National Analysis in January 2020.2018年有毒物质排放清单（Toxic Release Inventory，TRI）初步数据集由2018年度的TRI相关数据构成。使用者需留意，尽管此类初步数据已通过在线TRI报告软件内置的基础数据质量核查环节，但尚未完成完整的TRI数据质量审核流程。此外，美国环境保护署（Environmental Protection Agency，EPA）未对上述数据进行汇总、梳理，亦未提供任何相关分析或解读。借助该初步数据集，使用者可开展以下三类工作：其一，查明某一特定地理区域（例如美国邮政编码区域）内运营的TRI设施数量；其二，明确TRI设施所管控的化学物品种类及对应管理规模；其三，查询某一特定设施是否在最近一个日历年度内启动了污染预防相关活动。该机构将于2019年8月至9月期间，根据设施提交的最新信息多次更新该数据集。美国环境保护署计划于2019年10月发布经过完整质量核查的2018年TRI正式数据集，并于2020年1月发布《2018年TRI国家分析报告》。
