Aldrin (CAS 309-00-2) is a chemical tracked by the EPA Toxics Release Inventory (TRI) program under Section 313 of the Emergency Planning and Community Right-to-Know Act. The TRI requires industrial facilities above specified threshold quantities to disclose annual manufacturing, processing, and otherwise-used volumes, along with quantities released to air, water, land, and off-site transfers.

A carcinogen flag, when present on other chemicals in this database, reflects an assessment from EPA, IARC, or the National Toxicology Program rather than a TRI-specific determination. The PBT (persistent, bioaccumulative, toxic) status above carries a lower TRI reporting threshold than most listed chemicals, reflecting elevated regulatory concern about long-term environmental buildup. The largest individual disclosure in the current dataset comes from CHEMICAL WASTE MANAGEMENT OF THE NORTHWEST INC. in OR at 905 lbs.

TRI volumes are self-reported estimates, not measured stack emissions, and each pound counts equally regardless of chemical toxicity, so total pounds should not be equated with total risk. Inclusion of a chemical or facility in the TRI does not itself establish a health hazard; it documents the public right-to-know record. Consult EPA's IRIS (Integrated Risk Information System) and the Agency for Toxic Substances and Disease Registry for health-effect summaries.

Frequently Asked Questions

What is Aldrin in the EPA TRI? ▼
Aldrin (CAS Number: 309-00-2) is a chemical tracked by the EPA Toxic Release Inventory (TRI) program. It is not marked as a carcinogen in the TRI classification set. It is classified as a persistent bioaccumulative toxicant (PBT) in the TRI extract. 14 facilities in the United States report releasing this chemical to the EPA.
How much Aldrin is disclosed in U.S. TRI filings? ▼
U.S. facilities have reported a total of 2.0K lbs of Aldrin releases to the EPA Toxic Release Inventory across 14 facilities. Release quantities are self-reported estimates covering air, water, land, and off-site transfers. They are disclosure totals, not toxicity-weighted harm scores.
How does EPA TRI classify Aldrin? ▼
Aldrin is not marked as a carcinogen in the TRI classification set. It is also listed as a persistent bioaccumulative toxicant (PBT), which uses lower TRI reporting thresholds. TRI classification flags document inventory listing status; they are not a site-specific exposure or health diagnosis. For health-effect summaries see EPA IRIS and ATSDR toxicological profiles.
Which facilities disclose the most Aldrin? ▼
Chemical Waste Management of the Northwest Inc. in OR reports the largest disclosed release of Aldrin in this dataset, at 905 lbs. Most reporting facilities for this chemical fall under hazardous waste. Release data is self-reported annually to the EPA under the TRI program. View the full list of 14 facilities on this page.
What is the CAS number for Aldrin? ▼
The CAS (Chemical Abstracts Service) Registry Number for Aldrin is 309-00-2. CAS numbers are unique numerical identifiers assigned to every chemical substance described in the open scientific literature. This identifier is used to search scientific databases and regulatory filings.

Health Information

Persistent Bioaccumulative Toxicant (PBT): This chemical is classified as a PBT by the EPA. PBT chemicals are toxic, persist in the environment, and bioaccumulate in food chains. Because of these properties, even relatively small releases can pose a significant threat to human health and the environment over time.

Data comes from the EPA Toxic Release Inventory (TRI) program. Release quantities are self-reported by facilities and may represent estimates. The total shown aggregates reports across all facilities and reporting years.

PlainEnviro presents this data without advocacy framing. The presence of a chemical in the TRI database does not by itself indicate a health risk at current exposure levels. For health-related questions about specific chemical exposures, consult your local health agency or a toxicologist.
