Wildlife Toxicology

Study site locations: Massachusetts - Adult survival

Overwinter survival was reduced  by 5% in tree swallows breeding at highly-contaminated PCB sites based on model-averaged survival rates.  The annual survival averaged between 0.37 and 0.47 for PCB-contaminated females and between 0.40 and 0.48 for reference females.
