Agricultural Contributions of Antimicrobials and Hormones on Soil and Water Quality
The effects of silver nanoparticles on fathead minnow (Pimephales promelas) embryos
It is concluded that both dissolved and particulate forms of Ag elicited toxicity to fish embryos, and increased toxicity after sonication cannot be solely explained by dissolved Ag.

This review will focus on sex differentiation in teleost fishes and how these processes in fish early life stages may be impacted by environmental hormones which are known to contaminate aquatic environments.
Mercury in feathers from Chilean birds: influence of location, feeding strategy, and taxonomic affiliation.
Effects of clothianidin on aquatic communities: Evaluating the impacts of lethal and sublethal exposure to neonicotinoids
Low soil binding and high water solubility of neonicotinoid insecticides puts aquatic environments at high risk for contamination via runoff events, and high invertebrate predator mortality with increases in clothianidin concentration can result in a top-down trophic cascade in a community dominated by invertebrates.
Toxicological studies on silver nanoparticles: challenges and opportunities in assessment, monitoring and imaging.

Several proposed mechanisms of cytotoxicity based on recent research on the transport, activity and fate of Ag NPs at the cellular and organismic level are discussed, in conjunction with traditional and recently established methods of nanoparticle characterization.

This study indicates that runoff of terrestially applied urban and agricultural pesticides has been sufficient to induce resistance in a nontarget aquatic species on multiple, independent occasions and has far-reaching implications for biomonitoring programs in general and especially those relying on H. azteca.

Fecundity, egg size, and hatchability did not differ across treatments, but an increase in the frequency of fry abnormalities and a decrease in fry weights was observed at effluent exposures of 40% and higher.
Acute and chronic toxicity of atrazine and its metabolites deethylatrazine and deisopropylatrazine on aquatic organisms
The results suggest that short-term exposures of these chemicals to algae and amphipods to concentrations routinely detected in surface waters are unlikely to be a cause of concern, but the unexpected high sensitivity of Diporeia spp.
An evaluation of biomarkers of reproductive function and potential contaminant effects in Florida largemouth bass ( Micropterus salmoidesfloridanus) sampled from the St. Johns River.
