The Georgia Journal of Science is a refereed publication that is indexed in abstracting services such as BIOSIS and Current Contents, and is found in libraries throughout the United States and in many foreign countries. The Journal is published quarterly. The first issue consists of the abstracts of papers presented at the Annual Meeting and subsequent issues to the publication of scientific research.

PRESIDENT'S COMMENTS

I would like to thank all those that helped with the recent 2000 Annual Meeting held on the campus of Valdosta State University. The meeting was a great success and we had what I think was a record number of papers presented. I urge all of you to begin and finish those research projects that you have been on the back burner. It will be time for 2001 call for papers before you know it.

The millenium came in with a murmur rather that the bang that had been projected. However all of us need to take note of the things we use, consume and dispose. The ecology of the planet is still in great need of help. Even with the tremendous strides in technology, we are faced with major hurdles in maintaining biodiversity, reversing human population growth, global warming, fossil fuel depletion, etc. It seems a little ironic that the government can spend millions of dollars worrying about the fate of a single child, when only a small portion of that money could have been used to stop the extinction of several unique life forms.

If you have not been to the Georgia Academy home page, http://www.GaAcademy.org, you should visit and stop by frequently for updates. We are still looking for the right individual to become the Georgia Academy of Science’s Web Master. If interested, contact me at the address provided elsewhere in the Journal.

SHORTER COMMUNICATIONS - WIDEBAND PHOTOMETRY OF SATURN: 1999-2000 Richard W. Schmude, Jr. and Bill Hallsworth, Jr. 419 College Drive Barnesville, GA 30204 - ABSTRACT An SSP-3 solid-state photometer along with a 0.51 m Newtonian telescope and Johnson B, V, R and I filters were used to measure the brightness of Saturn between Sep. 5, 1999 and Jan. 6, 2000. The measured normalized magnitudes of Saturn, extrapolated to a solar phase angle of 0°, are: -8.53±0.02, -9.57±0.03, -10.26±0.02 and -10.46±0.04 in the B, V, R and I filters respectively. The solar phase angle coefficients for Saturn are: cB=0.032±0.008, cV=-0.035±0.011, cR=0.039±0.008 and cI=0.034±0.017. The measured V-filter magnitudes of Saturn were, on average, 0.018 magnitudes fainter than the predicted magnitudes in the Astronomical Almanac.
LONGER COMMUNICATIONS LEAD SHOT DEPOSITION IN WATERFOWL IMPOUNDMENTS BY COMMON SNIPE HUNTERS Daniel L. Forster and Gregory D. Balkcom Georgia Department of Natural Resources One Conservation Way Brunswick, GA 31520 fvalgame@cstel.net ABSTRACT Non-toxic shot restrictions were removed to allow small game hunters to use lead shot for common snipe (Capella gallinago) in drawndown waterfowl impoundments in Butler Island, Altamaha Waterfowl Management Area, Georgia, after the 1992-93 and 1993-94 waterfowl hunting seasons closed. Gizzards collected from waterfowl harvested 2 years prior to (N = 503) and after (N = 236) the regulation changed showed no significant increase in the number of shot ingested following removal of shot restrictions (P = 0.985). Soil samples collected before (N = 120) and after (N = 120) experimental snipe seasons indicated no difference in the number of lead shot present (P = 0.058). The quantity and timing of lead shot deposited by snipe hunters following winter drawdowns had little or no impact on lead shot availability or ingestion by waterfowl using this area the following fall.

NOTES ON THE BIOLOGY OF DYTISCUS CAROLINUS AUBé (COLEOPTERA: DYTISCIDAE) IN CENTRAL GEORGIA WITH A DESCRIPTION OF ITS MATURE LARVA Benjamin P. White, Jr. Georgia Depart. of Human Resources Macon, GA 31201 * E.H. Barman Depart. of Biology Georgia College & State University Milledgeville, GA 31061 ebarman@mail.gcsu.edu * Address correspondence to: ABSTRACT Larvae of Dytiscus carolinus Aubé were collected between mid-February and early April from an oligoxeric marsh and cultured to the adult stage. The occurrence of larvae suggests that oviposition occurred in January or early February in this Fall Line habitat and that adults could have emerged at the site as early as April. Analysis of the mature larva revealed structures that corresponded generally to that expected for Dytiscus, including secondary (pseudo-) segmentation of the proximal labial palp.

LEAD IN PAINT IN WEST GEORGIA: X-RAY DIFFRACTION, ICP AND HACH COLORIMETER ANALYSIS. Katie M. Tyrell, Tyler J. Boyles, Curtis L. Hollabaugh* and Cynthia A. Crews Department of Geosciences State University of West Georgia Carrollton, GA 30118 chollab@westga.edu * Author to whom correspondence should be addressed ABSTRACT The Environmental Protection Agency (EPA) and the Centers for Disease Control and Prevention (CDC) have declared lead, Pb, to be the number two environmental hazard in the United States. Ingestion of lead paints, contaminated dust, and soil is the leading cause of lead poisoning in young children. Therefore, a study was begun in the west Georgia region to determine lead content of paint on public and private buildings, the present crystalline state of lead in paint and to determine the lowest level of lead in paint detectable by X-ray diffraction. One interior and one exterior paint sample was obtained from 15 buildings built between 1843 and 1954 in Carrollton and Rome, Georgia. Thus, the present study is a reconnaissance study using minimum sampling methods. Samples were ground into a powder and analyzed for crystalline phases by X-ray diffraction methods. Weight percent of lead was determined by an EPA developed field-test method using a Hach colorimeter and by ICP analysis. Lead phases detected by X-ray diffraction include synthetic hydrocerussite (Pb3(CO3)2(OH)2), synthetic crocoite (PbCrO4), synthetic phoenicochroite (Pb2CrO4O), synthetic anglesite (PbSO4), and possible synthetic plattnerite (PbO2). Chemical analysis of the paints determined their lead contents range from 0.004 wt.% Pb to 10.8 wt.% Pb. Our results indicate that as the lead paint weathers it hydrates and is transformed from lead oxides and lead carbonates to hydrated lead compounds. Comparing the results from the Hach colorimeter and the X-ray diffraction methods show that the detection level of lead in paint by X-ray methods is between 1.05 and 2.67 wt.% lead.
