Summary

Story summary

Tulane University research shows brown anole lizards in New Orleans have the highest blood-lead levels among vertebrates.
These lizards tolerate lead levels exceeding 10 times the lethal thresholds for other species.
The study suggests possible genetic adaptations that may enhance their resilience, prompting a reevaluation of toxicity thresholds.
Brown anole lizards may indicate human lead exposure risks in contaminated environments.
