Hazardous Waste Testing

1. Introduction to Hazardous Waste Testing

Hazardous waste refers to solid waste listed in the National Catalog of Hazardous Wastes or identified as having hazardous characteristics according to the national hazardous waste identification standards and methods. Waste possessing one or more hazardous characteristics such as corrosivity, toxicity, flammability, or reactivity is classified as hazardous waste. Waste generated through the harmless utilization or disposal of hazardous waste that is no longer identified as having hazardous characteristics is classified as general waste.

2. Testing Items

Corrosivity: pH, corrosion rate

Acute toxicity: oral toxicity, dermal contact toxicity, inhalation toxicity

Leaching toxicity: inorganic elements and compounds, organic pesticides, non-volatile organic compounds, volatile organic compounds

Flammability: liquid flammability, solid flammability, gas flammability

Reactivity: reactivity with water or acid, oxidizing properties

Infectivity: highly toxic substances, toxic substances, carcinogenic substances, mutagenic substances, reproductive toxic substances, persistent organic pollutants
