Herbicides and Other Chemicals
All chemicals are assigned Lethal Dose (LD 50) numerical values through certain testing procedures. What LD 50 means is the dose or amount of a pesticide which can kill 50% of the test animals when eaten or absorbed through the skin. LD50 is expressed in milligrams of chemical per kilogram of body weight of the test animal (mg/kg). The lower the LD50 the more acutely toxic the chemical.
