Substance list by threshold
The National Pollutant Release Inventory (NPRI) tracks the release of substances to the environment, including their disposal or their transfer for recycling. This information is collected and published because they may pose a risk to the environment or to health.
The substances listed on the NPRI are organized into five parts, each having different reporting requirements. Detailed explanations can be found in the Guide for reporting to the NPRI.
Part 1A |
Commonly referred to as “core substances”, this group makes up the majority of substances on the NPRI list and most have been on it since the start of the NPRI. |
Part 1B | These substances are referred to as “alternate threshold substances” and have a lower reporting threshold than Part 1A substances. They may have significant environmental or human health impacts in small amounts. |
Part 2 | These substances are polycyclic aromatic hydrocarbons (PAHs) that may be used as commercial chemicals, incidentally manufactured in certain industrial processes, or contained in tailings. |
Part 3 | These substances are polychlorinated dibenzo-p-dioxins (dioxins), polychlorinated dibenzofurans (furans) and hexachlorobenzene that are released as by-products of industrial and combustion processes. They can be found as contaminants in pesticides, solvents or wood preservatives. |
Part 4 | These substances are known as criteria air contaminants (CACs), commonly released from combustion sources that can cause or contribute to air issues such as smog and acid rain. |
Part 5 | These substances are volatile organic compounds (VOCs) also known as “speciated VOCs” which are subject to additional reporting requirements. They are listed on the NPRI in three groups:
|
Before using the NPRI substance list
The Canada Gazette notice with respect to substances in the National Pollutant Release Inventory includes the official list of NPRI substances.
MPO | "Manufactured, processed or otherwise used" refers to the amount of the substance produced, prepared or used in any other way at a facility. |
PAH | Polycyclic aromatic hydrocarbons may be used as commercial chemicals, incidentally manufactured in certain industrial processes, or contained in tailings. |
VOC | Volatile organic compounds are substances that contribute to air pollution. They appear in each part of the NPRI substance list and have varying reporting requirements. |
CAS RN | Chemical abstract service registry number is the property of the American Chemical Society. Note: Any use or redistribution is not permitted without the prior, written permission of the American Chemical Society except as required in supporting regulatory requirements and/or for reports to the government when the information and the reports are required by law or administrative policy. |
NA - ## | Other substance identifiers used where no single CAS RN applies to a substance. |
Further information and definitions are available in our Glossary of terms.
Visit the History of reporting requirements page for more information on how the NPRI substance list has changed since the start of the program.
