Extracellular DNA in Environmental Samples: Occurrence, Extraction, Quantification, and Impact on Microbial Biodiversity Assessment

open access: yesApplied and Environmental Microbiology, 2021
Environmental DNA, i.e., DNA extracted directly from environmental samples, has been applied to understand microbial communities in the environment and to monitor contemporary biodiversity in the conservation context.

Simultaneous Method for Selected PBDEs and HBCDDs in Foodstuffs Using Gas Chromatography—Tandem Mass Spectrometry and Liquid Chromatography—Tandem Mass Spectrometry

open access: yesToxics, 2022
Flame retardants are added to consumer products to retard the ignition of combustible materials. Technical mixtures of polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCDD) were massively used for several decades.

Ferroin in dyes degradation by Fenton-like process: a chemical waste recycling perspective

open access: yesWater Science and Technology, 2021
Published literature describes the formation of the Fe (II)–phenanthroline complex (ferroin) as a stop way for Fenton processes, reducing radical yield. By contrast, this study presents evidence that ferroin can be activated by UVA in mildly acidic media

Toward a Universal Unit for Quantification of Antibiotic Resistance Genes in Environmental Samples.

open access: yesEnvironmental Science and Technology, 2023
Surveillance of antibiotic resistance genes (ARGs) has been increasingly conducted in environmental sectors to complement the surveys in human and animal sectors under the "One-Health" framework. However, there are substantial challenges in comparing and

Identification and Quantification of Micro-Bioplastics in Environmental Samples by Pyrolysis-Gas Chromatography-Mass Spectrometry.

open access: yesEnvironmental Science and Technology, 2022
Bioplastics are materials that are biobased and/or biodegradable, but not necessarily both. Concerns about environmental plastic pollution are constantly growing with increasing demand for substituting fossil-based plastics with those made using ...

An Infrared Standard Curve Method for Calculating the Total Amount of Petroleum in Environmental Samples

open access: yesYankuang ceshi, 2022
BACKGROUND Petroleum oil is one of the necessary indicators for environmental monitoring, which mainly exists in the form of hydrocarbons. Therefore, infrared spectrophotometry is one of the most reliable methods to determine the total amount of ...

Computer-Assisted Analysis of Microplastics in Environmental Samples Based on μFTIR Imaging in Combination with Machine Learning

open access: yesEnvironmental Science and Technology Letters, 2021
The problem of automating the data analysis of microplastics following a spectroscopic measurement such as focal plane array (FPA)-based micro-Fourier transform infrared (FTIR), Raman, or QCL is gaining ever more attention.

Adaptive sampling for environmental robotics [PDF]

open access: yesIEEE International Conference on Robotics and Automation, 2004. Proceedings. ICRA '04. 2004, 2004
The capabilities and distributed nature of networked sensors are uniquely suited to the characterization of distributed phenomena in the natural environment. However, environmental characterization by fixed distributed sensors encounters challenges in complex environments.
