The aim of this project was to obtain a baseline understanding and investigate the concentration of mercury (Hg) in the tissue of terrestrial arthropods. The 4-month sampling campaign took place around Monterey Bay, California. Total mercury (HgT) concentrations (x +/- A SD, dry weight) for the captured specimens ranged from 22 to 188 ng g(-1) in the Jerusalem crickets (Orthoptera: Stenopelmatidae); 65-233 ng g(-1) in the camel crickets (Orthoptera: Rhaphidophoridae); 25-227 ng g(-1) in the pill bugs (Isopoda: Armadillidiidae); 19-563 ng g(-1) in the ground beetles (Coleoptera: Carabidae); 140-441 ng g(-1) in the variegated meadowhawk dragonflies (Odonata: Libellulidae); 607-657 ng g(-1) in the pacific spiketail dragonflies (Odonata: Cordulegastridae); and 81-1,249 ng g(-1) in the wolf spiders (Araneae: Lycosidae). A subset of samples analyzed for monomethyl mercury (MMHg) suggest detrital pill bugs have a higher MMHg/HgT ratio than predatory ground beetles.
