  "id": "MLC-T-ENV-017402",
  "term": "Minimally Toxic Effect",
  "field": "Environment",
  "definition": "Substance must pass either OECD 201, 202, and 203 for acute toxicity testing, or OECD 210 and 211 for chronic toxicity testing. For purposes of the standards, equivalent toxicity data for marine species, including methods ISO/DIS 10253 for algae, ISO TC147/SC5/W62 for crustacean, and OSPAR 2005 for fish, may be substituted for OECD 201, 202, and 203. If a substance is evaluated for the formulation and main constituents, the LC50 of fluids must be at least 100 mg/L and the LC50 of greases, two-stroke oils, and all other total loss lubricants must be at least 1000 mg/L. If a substance is evaluated for each constituent substance, rather than the complete formulation and main compounds, then constituents comprising less than 20% of fluids can have an LC50 between 10-100 mg/L or a no-observed-effect concentration (NOEC) between 1-10 mg/L, constituents comprising less than 5% of fluids can have an LC50 between 1-10 mg/L or a NOEC between 0.1-1 mg/L, and constituents comprising less than 1% of fluids, can have an LC50 less than 1 mg/L or a NOEC between 0-0.1 mg/L.",
