1 Overview of Lake Apopka North Shore Pesticide Research by Michael F. Coveney, PhD SJRWMD Harris Chain of Lakes Restoration Council 6 February 2015 Bureau of Environmental Sciences St. Johns River Water Management District Palatka, Florida, USA mcoveney@sjrwmd.com
2 Overview of NSRA Pesticide Research by SJRWMD Overview of NSRA extent of farming, land elevations, subsidence, current flooding Bird mortality in 1998/99 Ensuing research program by SJRWMD and NRCS Remediation and continued restoration

4 Lake Apopka Lake Apopka Development of Farms on the North Shore of Lake Apopka Lake Apopka Lake Apopka Shallow marsh Shrub swamp Hardwood swamp Wet prairie Farm in prep Farm
5 Reduce phosphorus loading through wetland restoration on former farms In ,480 Acres (22%) In ,730 Acres (43%) In ,170 Acres (71%) In ,660 Acres (100%)
6 Lake Apopka North Shore Restoration Area Christmas 1998 bird count 176 species Bird mortality winter 1998/99 (despite environmental site assessments, remediation, ecological risk assessments) Drained the fields Organochlorine pesticide residues responsible in part Research program on distribution, bioaccumulation, and fate in organic soils
7 Bird Mortality on Site 9/98 3/99 White pelicans 441 Herons and egrets 135 Wood storks 43 Other species 57 Total 676.
8 NSRA Bird Mortality Questions for SJRWMD/NRCS 1. How did lethal OCP levels accumulate in birds? 2. How to proceed with restoration of wetlands with acceptable risk? Availability of weathered soil OCPs to biota Transfer of OCPs from soil fish and fish birds Roles of soil TOC and OCP levels in determining exposure Distribution of OCPs among bird tissues
9 SJRWMD/NRCS Research Program Formation of Technical Advisory Group and Expert Review Group Large-scale sampling of soils Contract with Exponent for forensic analyses Pesticide bioaccumulation studies Soil Fish and Fish Birds
10 Cooperators with SJRWMD/NRCS U.S. Fish & Wildlife Service U.S. Environmental Protection Agency Fl. Fish and Wildlife Conservation Commission Fl. Dept of Health Fl. Dept of Agriculture and Consumer Services Fl. Dept. of Environmental Protection University of Florida U. S. Geological Survey Lake County Lake Co. Water Authority Orange County Audubon Society Friends of Lake Apopka

La Point, Ph.D. University of North Texas Avian toxicology P. Suresh C. Rao, Ph.D. Purdue University Soil biogeochemistry Gary Rand, Ph.D. Florida International University Ecological toxicology James Sikarskie, D.V.M. Michigan State University Wildlife veterinarian
12 Pesticide Residues of Interest 4,4'-DDD, 4,4'-DDE; 4,4'-DDT alpha-chlordane; cis-nonachlor; gamma-chlordane; heptachlor; heptachlor epoxide; oxychlordane; trans-nonachlor Dieldrin Toxaphene
13 Distribution of Toxaphene
14 Distribution of DDE
15 DDE Concentrations in Bird Brains Analyzed at En Chem Control birds Concentration (mg/kg) Black- crowned Night Heron Great Blue Heron White Ibis White Pelican Wood Stork = brain concentrations considered hazardous (Stickel 1980)
16 Dieldrin Concentrations in Bird Brains Analyzed at En Chem Concentration (mg/kg) Control birds Black- crowned Night Heron Great Blue Heron White Ibis White Pelican Wood Stork Range of brain concentrations considered hazardous (Ohlendorf et al. 1981)
17 Toxaphene Concentrations in Bird Brains Analyzed at En Chem 6 4 Control birds Concentration (mg/kg) Black- crowned Night Heron Great Blue Heron White Ibis White Pelican Wood Stork Range of concentrations considered hazardous (4 mg/kg in pigs)
18 Exponent s Conclusions Page 6-4. Overall, application of epidemiological criteria to the mortality event does not produce strong evidence either supporting or refuting the hypothesis that mortality was a result of exposure to organochlorine pesticides. In other words, Exponent could not reach a conclusion on the cause of the mortality.
19 District s Conclusions Weight of Evidence OCP toxicosis caused, or contributed to, the deaths of many of the birds Primary agents of toxicosis were toxaphene and dieldrin Primary route of exposure was soils to fish to birds
20 Bioaccumulation Studies Soil fish Birds Laboratory microcosms Field mesocosms Great egret feeding study Fish sausages measured, controlled dose
21 Microcosm Study Bioaccumulation soil fish Tank experiment (~700 L, 1.2 m diam.) Soils with a range of TOC and OCPs 10 soil types +3 controls in triplicate (total 39 tanks) Measured OCP accumulation and lipids in stocked mosquitofish and crayfish Run for 16 weeks
22 Biota Sediment Accumulation Factor (BSAF) BSAF is one way to calculate the bioaccumulation of lipophilic ( fat-loving ) compounds in the environment BSAF = OCP in fish lipid OCP in soil C BSAF = (OCP fish µg/kg wet wt) / (lipid fish µg/kg wet wt) (OCP sed µg/kg dry wt) / (TOC sed µg/kg dry wt)

Covered with netting 3 shallow ponds (0.75 acre, 0.3 ha) at low medium high soil OCP levels 2 deeper ponds (0.25 acre, 0.1 ha) at high soil OCP levels Stocked with tilapia, mosquitofish, crayfish, sunfish, bullhead catfish Operated approx. 6 yr

35 Changes in Toxaphene in Fish
36 Changes in DDE in Fish
37 Results - Reduction in OCPs in Soil and Fish First-order rate constants calculated for 1.9 to 6.1 yr for open water soils, 1.9 to 5.3 yr for marsh soils, and 2.0 to 6.1 yr for open water fish.
38 Results - BSAFs n = 229 or 314 fish samples for marsh and 114 samples for open water. Chlordanes not shown. Flooding times 1.1 to 2.7 yr for marsh and 1.1 to 3.5 for open water mesocosms.

40 Bird Feeding Study Bioaccumulation fish birds Raise fish in two 0.25-acre ponds on high OCP soils on the NSRA Feed fish to captive great egrets Measure bioaccumulation of weathered OCPs from NSRA fish Kinetics of accumulation Distribution of OCPs among tissues Possible remobilization of OCPs from fat to brain
41
42 Fish sausages measured, controlled dose
43 Results Bird Feeding Study Found long half-lives for OCPs in birds OCP concentrations in birds showed constant ratios among organs Evidence that OCPs were mobilized from fat to brain upon fasting Birds did not die but may have sickened on 100% contaminated fish diet
44 Results Bioaccumulation Studies BSAF bioaccumulation model works despite varying organic content of soils, varying fat content of fish, and varying OCP levels in soils. BSAFs 2 to 4 times higher in open water vs emergent marsh OCPs move from fat to critical tissues when birds metabolize fat reserves Half-life of weathered toxaphene in birds much longer than earlier believed OCPs degrade under flooded conditions
