This is a collection of data on the contamination of water, fish, and sediments in Biscayne National Park and in canals that discharge into the national park. The water data are estimations of their concentrations in water based on sampling with passive water samplers (semi-permeable membrane devices and polar organic chemical integrative samplers). Also in this data set are estrogen equivalencies for the chemical mixtures in the polar organic chemical integrative samplers.
|
The data set contains raw data for pesticide (naled) residues on samplers collected after aerial applications over the National Key Deer Refuge in the Florida Keys, and biological response (cholinesterase activity in butterflies and mosquito mortality) for organisms co-located with the residue samplers.

Sawgrass (Cladium jamaicense) samples were collected from marshes on five different keys (Big Pine, Torch, Ramrod, Cudjoe, and Sugarloaf Keys) within National Key Deer Refuge in January and June of 2015 and analyzed for contamination by the mosquito control insecticide permethrin. Permethrin was detected on 17 of 57 samples collected in January while it was detected on 40 of 56 samples collected in June. The concentrations on samples collected in January (below detection to 16 ng/g ww) were lower than concentrations on samples collected in June (below detection to 57.7 ng/g).

Recent concern for the adverse effects from neonicotinoid insecticides has centered on risk for insect pollinators in general and bees specifically. However, natural resource managers are also concerned about the risk of neonicotinoids to conservation efforts for the monarch butterfly (Danaus plexippus) and need a tool to estimate risk for wild monarch butterflies exposed to clothianidin. In the present study, monarch butterfly larvae were exposed to contaminated milkweed plants from hatch until pupation, and the effects upon larval survival, larval growth, pupation success, and adult mass were measured. Soils dosed with a granular insecticide product lead to average clothianidin concentrations of 10.8 - 843 ng/g...
