Contaminants of Emerging Concern in the Environment
Some chemicals that we use in our everyday lives including medicines (such as prescription and non-prescription drugs), personal hygiene products (for example, soaps, disinfectants, …) and their chemical additives (such as preservatives) are present in the environment and associated with various sources such as municipal wastewater treatment plants, runoff from agricultural and urban land surfaces, and septic systems. These contaminants are referred to collectively as “contaminants of emerging concern” and represent a shift in traditional thinking as many are produced industrially yet are dispersed to the environment from domestic uses.
This investigation identifies and quantifies the environmental sources, presence, and magnitude of environmental contaminants with the underlying theme of understanding the contaminants from their source to a “receptor organism.” The goal of the investigation is to understand the actual versus the perceived health risks to humans or wildlife due to low-level exposures from understudied chemical contaminants in the environment.
Study findings indicate that cyanobacteria and cyanotoxins were not associated with mussel mortality at the concentrations present in Lake Erie during a recent study (2013-15), but mussel growth was lower at sites with greater microcystin concentrations. ...
New study evaluated if predicted environmental concentrations (PECs) of pharmaceuticals (based on pharmaceutical usage data, degree of metabolism in humans, removal in wastewater treatment plants (WWTPs), and environmental dilution), reflect actual measured environmental concentrations (MECs) in two rivers of different sizes and demographics. ...
This pilot study provided baseline data on avian influenza virus (AIV) occurrence in groundwater underlying poultry farms and documented the challenges for conducting a pathogen transport study during a disease outbreak. ...
