Chlordecone belongs to the class of persistent organochlorine pesticides that are remarkably resistant to environmental degradation. Even though their use was banned in the United States in 1978, these compounds can still be detected in both humans and wildlife throughout the world. Previous work has shown that the pretreatment of...
Rainbow trout were exposed to aluminum at pH 7.25 and
8.25 and four hardnesses (10, 30, 80, and 120 ppm CaCO₃)
for 96 hours in a continuous-flow system and mortality and
aluminum accumulation in the gills were determined.
Temperature, pH, and dissolved oxygen were measured
daily for each treatment. Dissolved...
Temperature influences the incidence of chemically induced cancer in fish,
with warmer temperatures being associated with higher cancer incidence. The
mechanisms of temperature-modulated chemical carcinogenesis in fish, however,
have not been described in detail. Therefore, one primary objective of this study
was increased understanding of how temperature-modulated genotoxicity of 7,12-...
The atmospheric transport and deposition of semi-volatile organic compounds (SOCs), including current and historic use pesticides, polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), to mountain ecosystems may result in the exposure of tadpoles to these SOCs. This exposure has been implicated in amphibian population declines in California. Tadpoles encounter...
