Scientists issue warning after discovering cancer-causing contaminants in major waterways: ‘This is a really big deal’
MSN online

According to the study’s lead author, Tyler Frankel, who was quoted in Phys.org, coal ash contaminants increase in concentration as they work their way up through the food web, threatening a number of predatory fish and birds. “These waterways serve as important routes for several migratory fish species and sensitive nursery habitats for various endemic species,” Frankel said, per Phys.org. “Our work highlights the importance of considering this exposure pathway in conservation strategies.”
Cancer-causing metals leak into water near coal ash landfills

Researchers from the University of Mary Washington have discovered alarming levels of cancer-causing metals in both the sediments and fish of a Chesapeake Bay tributary situated near a coal ash landfill. This research, led by Dr. Tyler Frankel, highlights previously overlooked dangers posed by trace metal contamination in aquatic ecosystems.

Aqueous exposure to the progestin, levonorgestrel, alters anal fin development and reproductive behavior in the eastern mosquitofish (Gambusia holbrooki)
General and Comparative Endocrinology (2016)Endogenous progestogens are important regulators of vertebrate reproduction. Synthetic progestins are components of human contraceptive and hormone replacement pharmaceuticals. Both progestogens and progestins enter the environment through a number of sources, and have been shown to cause profound effects on reproductive health in various aquatic vertebrates.
Exposure to the contraceptive progestin, gestodene, alters reproductive behavior, arrests egg deposition, and masculinizes development in the fathead minnow (Pimephales promelas)
Environmental Science and Technology (2016)Endogenous progestogens and pharmaceutical progestins enter the environment through wastewater treatment plant effluent and agricultural field runoff. Lab studies demonstrate strong, negative exposure effects of these chemicals on aquatic vertebrate reproduction. Behavior can be a sensitive, early indicator of exposure to environmental contaminants associated with altered reproduction yet is rarely examined in ecotoxicology studies.
Exposure effects of levonorgestrel on oogenesis in the fathead minnow (Pimephales promelas)
Environmental Toxicology and Chemistry (2017)Frankel, TE, Yonkos, L and Frankel, JS.
The synthetic progestin levonorgestrel is commonly utilized in human oral contraceptives. It enters the environment as a component of wastewater treatment plant effluent, and has been measured at low ng/L concentrations in surface waters. It has been shown to activate fish androgen receptors, causing the physical masculinization of females, changes in reproductive behavior, and decreases in fecundity.
Exposure to levonorgestrel increases nest acquisition and decreases sperm motility in male fathead minnows (Pimephales promelas)
Environmental Toxicology and Chemistry (2018)Frankel, TE, Yonkos, LT, Ampy, FR, and Frankel, JS.
Progestins are utilized as a component of human contraceptives, and commonly enter the environment via wastewater treatment plant effluent. Certain progestins activate fish androgen receptors and cause decreases in fecundity and masculinization of females. We used a nest acquisition assay and computer‐assisted sperm analysis to examine the effects of levonorgestrel on male fathead minnow (Pimephales promelas) reproductive fitness.
Assessing the Impacts of Methoxychlor Exposure on the Viability, Reproduction, and Locomotor Behavior of the Seminole Ramshorn Snail (Planorbella duryi)
Environmental Toxicology and Chemistry (2020)Frankel, T.E., Bohannon, M.E. and Frankel, J.S.
In the present study, the effects of short-term methoxychlor exposure on the viability, reproduction, and locomotor behavior of adult seminole ramshorn snails (Planorbella duryi) was assessed. To examine impacts on viability and behavior, individuals were exposed to a water control, vehicle control, or 12.5, 50, 100, 250, 500, or 1000 μg/L of methoxychlor for 48 h; and differences in mortality and locomotor behavior assessed using the freely available ToxTrac software.
