Special Issue Information

Dear Colleagues,

Emerging contaminants (ECs) constitute a suite of manmade or naturally occurring chemicals for which concerns have recently been mounting. Recent advances in analytical techniques have facilitated the discovery and quantitation of numerous ECs. The most prevalent ECs in the aquatic environment include micro- and nanoplastics, per- and polyfluoroalkyl substances, disinfection byproducts, manufactured nanomaterials, and pharmaceuticals and personal care products.

The aquatic environment continually suffers from contamination due to elevated levels of ECs, which result from multiple pollution sources, including storm runoff, fisheries, landfill leachate, as well as municipal, industrial, and agricultural wastewater discharge. Due to the ubiquity of numerous ECs in the water, their ecotoxicological effects on the aquatic organisms became known and include reduced eco-function and nutritional quality, bioaccumulation and biomagnification, and various acute and chronic toxicities. Therefore, establishing state-of-art protocols for pollution source identification and risk assessment of ECs in various aquatic compartments is urgently needed.

This Special Issue aims to collect original, high-quality articles related to the identification of the key sources, transfer mechanisms, and environmental behavior of ECs and discuss the hazards and risks that ECs pose to the aquatic ecosystems. Research papers covering multidisciplinary topics as well as review papers with new perspectives are welcome for submission

The Marcellus shale is an unconventional reservoir of significant economic potential with Total Organic Carbon (TOC) ranging from 1 to 20%. Hydraulic fracturing is used to extract the shale’s resources, which requires large amounts of water and can result in mineral-rich flowback waters containing hazardous contaminants. This study focuses on a geochemical analysis of the flowback waters and an evaluation of the potential environmental impacts on water and soil quality. Drilled core samples from different depths were treated with lab-prepared hydraulic fracturing fluids. Rock samples were analyzed using Energy Dispersive Spectroscopy (EDS), while effluents’ chemical compositions were obtained using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). A comparison of results from drilled core samples treated with additives for hydraulic fracturing to those treated with deionized (DI) water confirms that, as expected, the major elements present in the effluent were Ca, Ba, and Cl in concentrations greater than 100 µg/L. The most concerning elements in the effluent samples include As, Ca, Cd, Pb, Se, S, K, Na, B, Mo, and Mn, with Cd and Cr values averaging 380 and 320 µg/L, respectively, which are above safe limits. Se concentrations and high levels of Ca pose major safety and scaling concerns, respectively. We also compared Marcellus shale drilled core samples’ geochemical reactivity to samples collected from an outcrop. Full article
