What is the oral LD50 range for a product classified as slightly toxic?

The classification of toxicity for chemicals, including herbicides, is often determined by the oral LD50 value, which is the lethal dose required to kill 50% of a test population and is expressed in milligrams of substance per kilogram of body weight (mg/kg). For products classified as slightly toxic, the oral LD50 typically falls within the range of 500 to 5000 mg/kg.

This range indicates that substances categorized as slightly toxic may pose some risk if ingested but are generally considered less hazardous than those with lower LD50 values. The higher the LD50 value, the less toxic the substance is perceived to be, as it requires a larger quantity to achieve detrimental effects. Consequently, having an LD50 between 500 and 5000 mg/kg signifies that while there is potential danger, it is comparatively mild in toxicity when assessing potential health risks associated with accidental ingestion.
