EPA TRI Chemical

Strychnine and Salts

Q: What is Strychnine and Salts in the EPA TRI?

Strychnine and Salts (EPA TRI Category Code: N746) is a chemical tracked by the EPA Toxic Release Inventory (TRI) program. It is not marked as a carcinogen in the TRI classification set. 6 facilities in the United States report releasing this chemical to the EPA.

Q: How much Strychnine and Salts is disclosed in U.S. TRI filings?

U.S. facilities have reported a total of 86.8K lbs of Strychnine and Salts releases to the EPA Toxic Release Inventory across 6 facilities. Release quantities are self-reported estimates covering air, water, land, and off-site transfers. They are disclosure totals, not toxicity-weighted harm scores.

Q: How does EPA TRI classify Strychnine and Salts?

Strychnine and Salts is not marked as a carcinogen in the TRI classification set. 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.

Q: Which facilities disclose the most Strychnine and Salts?

Chemical Waste Management in AL reports the largest disclosed release of Strychnine and Salts in this dataset, at 85.0K 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 6 facilities on this page.

Q: Why is Strychnine and Salts listed under code N746 instead of a CAS number?

N746 is an EPA TRI Category Code, not a CAS Registry Number. EPA assigns category codes (N-prefix and K-prefix) to chemical groups that share reporting requirements, for example, "Strychnine and Salts" covers many distinct compounds aggregated for TRI reporting. Individual constituents may have their own CAS Registry Numbers (e.g., elemental Lead is CAS 7439-92-1), but the group is reported under the single TRI Category Code.

Strychnine and Salts (EPA TRI Category Code N746) 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 largest individual disclosure in the current dataset comes from CHEMICAL WASTE MANAGEMENT in AL at 85.0K 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.

Health Information

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.
