National Pollutant Release Inventory (NPRI) - 2012 and 2013

The National Pollutant Release Inventory (NPRI) is Canada's public inventory of pollutant releases (to air, water and land), disposals and transfers for recycling.

Established in 1992, the NPRI currently collects information on the release, disposal and transfer of more than 320 substances.

**Releases** are direct discharges of pollutants into the environment (air, water, land).

**Disposals** manage substances and limit their release. Disposals include landfill, land application and underground injection and can be done at the facility (on-site) or elsewhere (off-site).

**Transfers** send substances elsewhere for recycling, energy recovery or for treatment before final disposal.

There are important factors that should be considered prior to the use and interpretation of NPRI data. Additional information is available on the [NPRI web site](https://www.canada.ca/en/environment-climate-change/services/national-pollutant-release-inventory/using-interpreting-data.html).

国家污染物排放清单（NPRI）系加拿大公开的污染物排放（对空气、水体和土地）、处置及回收转移的目录。该清单自1992年设立以来，目前已收集了超过320种物质的排放、处置及转移信息。

**排放**指污染物直接排放至环境（空气、水体、土地）。

**处置**涉及对物质的管理以限制其排放。处置方式包括填埋、土地施用和地下注入，可于设施内（现场）或设施外（异地）进行。

**转移**指将物质转移至其他地点进行回收、能量回收或最终处置前的处理。

在使用和解读NPRI数据之前，应考虑一些重要因素。更多相关信息可访问[NPRI网站](https://www.canada.ca/en/environment-climate-change/services/national-pollutant-release-inventory/using-interpreting-data.html)。
