The environmental fate of polymers has attracted growing attention in the academic, industrial, and regulatory communities as well general public global production use continue to increase. Biodegradable especially have drawn significant interest. Polymer biodegradation literature published over past decade was reviewed compare test methods commonly used for evaluating polymer biodegradation, identify key areas improvement. This paper examines aspects study design such physical form...
Silencing genes of a pest with double-stranded RNA (dsRNA) is promising new management technology. As part the environmental risk assessment for dsRNA-based products, fate and potential adverse effects to on-target organisms should be characterized. In present study, nonbioactive dsRNA was spiked into water column sediment microcosm mimic drift from spray application run off unbound or transport plant tissues. Dissipation in partitioning determined. The rapidly dissipated below limit...
Poly(acrylic acid) (PAA) is produced on an industrial scale and widely-used in applications such as personal care products cleaning formulations that end up "down-the-drain." Relatively high molecular weight PAA considered poorly biodegradable, but little known about the biodegradability of low at wastewater treatment plant according to current regulatory Organization for Economic Co-operation Development (OECD) standards. The synthesis, separation, characterization a series ultralow...
Natural and chemically modified polysaccharides are extensively employed across a wide array of industries, leading to their prevalence in the waste streams industrialized societies. With projected increasing demand, pressing challenge is swiftly assess predict biodegradability inform development new sustainable materials. In this study, we developed scalable method evaluate polysaccharide breakdown by measuring microbial growth analyzing genomes. Our approach, applied with various...
Extensive use of the agricultural herbicide atrazine has led to contamination numerous ground and surface water bodies. Research shown that it can have a variety negative impacts on non-target organisms in environment. Phytoremediation is one strategy been studied remove contamination. This paper investigates hypothesis switchgrass (Panicum virgatum) exude metabolites after uptake degradation, which suggested by prior research. Pots planted with were treated 4 ppm solution spiked...
Current biodegradation screening tests are not specifically designed for persistence assessment of chemicals, often show high inter- and intra-test variability, give false negative results. Based on previous studies recommendations, an international ring test involving 13 laboratories validated a new method marine with focus improving the reliability to determine environmental degradation potential chemicals. The incorporated increased bacterial cell concentrations better represent microbial...
The continuing use of transgenic crops has led to an increased interest in the fate insecticidal crystalline (Cry) proteins environment. Enzyme-linked immunosorbent assays (ELISAs) have emerged as preferred detection method for Cry environmental matrices. Concerns exist that ELISAs are capable detecting fragments proteins, which may lead overestimation concentration these Five model systems were used generate Cry1Ab protein, then analyzed by and bioassays. Fragments from 4 not detectable...
The use of transgenic crops expressing one or more crystal (Cry) proteins for insect management has grown dramatically since their introduction nearly 2 decades ago. However, many questions surrounding the environmental fate these still persist. One area particular interest is possible detection Cry protein fragments by antibodies used in ELISA kits. A model system approach to generate environmentally relevant simulating conditions and digestive enzymes that are known exist environments...
