Abstract

Unweathered crude and refined oils are known to be very toxic to the embryos of aquatic birds (ALBERS 1977, 19781 SEARO et ale 1978, WHITE et al. 1979, McGILL & RICHMOND 1979, and others) but the toxicity of weathered petroleum is not as well established. The toxicity of Prudhoe Bay crude oil and No. 2 fuel oil to embryos of mallard ducks (Anas platyrhynchos) decreased only after 3 weeks and 2 weeks of weathering on a large container of fresh water (SZARO et al. 1980). Ten microliters (uL) of 4 week-old Libyan crude oil caused a significant increase in mortality among embryos of Louisiana herons (Hydranassa tricolor) but the same amount of fresh oil did not cause a significant increase in mortality. However, embryos of laughing gulls (Larus atricilla) were not significantly affected by I0 uL of 4 or 8 week-old weathered Libyan crude oil nor i0 UL of fresh oil (MACKO& KING 1980). Crude ell (i0 uL) recovered from the water surface (age unknown, but presumably slightly weathered) near the IXTOC-I oil spill site in the Gulf of Mexico did not significantly reduce the survival of mallard embryos by day 18 of incubation (D. HOFFMAN, unpublished data).

Sensitivity of warm water fishes and rainbow trout to selected contaminants

Guidelines for developing water quality standards allow U.S. states to exclude toxicity data for the family Salmonidae (trout and salmon) when deriving guidelines for warm-water habitats. This practice reflects the belief that standards based on salmonid data may be overprotective of toxic effects on other fish taxa. In acute tests with six chemicals and eight fish species, the salmonid, Rainbow Trout ( Oncorhynchus mykiss ), was the most sensitive species tested with copper, zinc, and sulfate, but warm-water species were most sensitive to nickel, chloride, and ammonia. Overall, warm-water fishes, including sculpins (Cottidae) and sturgeons (Acipenseridae), were about as sensitive as salmonids in acute tests and in limited chronic testing with Lake Sturgeon ( Acipenser fulvescens ) and Mottled Sculpin ( Cottus bairdi ). In rankings of published acute values, invertebrate taxa were most sensitive for all six chemicals tested and there was no trend for greater sensitivity of salmonids compared to warm-water fish.

Lead exposure of red-shouldered hawks during the breeding season in the central Appalachians, USA

Lead is toxic to humans and wildlife. Most studies of lead exposure of raptors focus on the winter, non-breeding season when they scavenge heavily. We evaluated blood lead concentrations (BLCs) of red-shouldered hawks (Buteo lineatus) during the non-scavenging season in the eastern United States. BLCs of 53 of 70 hawks were above the limit of detection ( x¯ = 9.25 µg/dL ± 19.81; ± SD). Adult hawks had higher BLCs ( x¯ = 12.86 µg/dL ± 24.72) than did nestlings ( x¯ = 3.25 µg/dL ± 2.62; p ≤ 0.001, χ2 = 13.2). There was no difference in BLCs of adult hawks among physiographic provinces but there were differences between urban and non-urban settings (p = 0.04, χ2 = 4.2). Soils and invertebrate hawk prey also had quantifiable lead concentrations. Our work shows that red-shouldered hawks are exposed to lead when not scavenging, and suggests pathways by which these birds may be exposed.

Effects of the neonicotinoid insecticide clothianidin on southern leopard frog (Rana sphenocephala) tadpole behavior

Neonicotinoid insecticides are highly water soluble with relatively long half-lives, which allows them to move into and persist in aquatic ecosystems. However, little is known of the impacts of neonicotinoids on non-target vertebrates, especially at sublethal concentrations. We evaluated the effects of the neonicotinoid clothianidin on the behavior of southern leopard frog tadpoles ( Rana sphenocephala ) after a 96-h exposure at 6 concentrations, including 0 (control), 0.375, 0.75, 1.5, 3.0, 6.0 µg/L. We quantified total displacement, mean velocity, maximum velocity, and time spent moving of tadpoles for 1 h post-exposure. Total displacement and mean velocity of tadpoles decreased with clothianidin exposure. Maximum velocity decreased linearly with concentration, but there was no relationship between time spent moving and clothianidin concentration. Our results suggest exposure to clothianidin at sublethal concentrations can affect movement behavior of non-target organisms such as tadpoles.
