Environ Pollut 159:466-73. 2011..Based on survival, loss of body weight, diminished food intake, changes in liver, kidney, and testes, and increased blood urea nitrogen, these data suggest a LOAEL of 15 mg/kg-d and a NOAEL of 5 mg/kg-d in S. occidentalis... - Effects of inorganic lead on Western fence lizards (Sceloporus occidentalis)Christopher J Salice
US Army Center for Health Promotion and Preventive Medicine, Aberdeen Proving Ground, MD 21010, USA
Environ Pollut 157:3457-64. 2009..Of these, Pb-induced changes in body weight are most useful for ecological risk assessment because it is linked to fitness in wild lizard populations.
