Per- and polyfluoroalkyl substances (PFAS) are a family of fluorinated organic compounds anthropogenic origin. Due to their unique chemical properties, widespread production, environmental distribution, long-term persistence, bioaccumulative potential, associated risks for human health, PFAS have been classified as persistent pollutants significant concern. Scientific evidence from the last several decades suggests that occurrence in environment correlates with adverse effects on health ecology. The presence aquatic demonstrates close link between anthroposphere hydrological cycle, concentrations surface groundwater range value along ng L−1–μg L−1 scale. Here, we critically reviewed research published decade global distribution environment. Ours is first paper evaluate at continental scale evolving regulatory responses manage mitigate posed by PFAS. review reports despite being phased out—they detected different continents irrespective level industrial development.

Occurrence of per- and polyfluoroalkyl substances (PFAS) in soil: Sources, fate, and remediation

Soil & Environmental Health, Journal Year: 2023, Volume and Issue: 1(1), P. 100004 - 100004

Published: March 1, 2023

Per- and polyfluoroalkyl substances (PFAS) are being widely investigated for their distribution remediation in the environment. It is crucial to consider interactions of PFAS between soil other media ecosystem, including air, water, plants, when studying fate transport soil, while few studies have taken such an integrative approach. This review examined potential input from landfill by analyzing both concentration each source mechanisms which a impacted these sources. was found that air (on average 101−2 ​pg/m3) leachates 100-2 ​ng/L) main sources soil. Many factors, as solution pH cations, influence sorption desorption water-soil interface, but no single factor deterministic.

An integrated approach of remote sensing and geospatial analysis for modeling and predicting the impacts of climate change on food security

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: Jan. 19, 2023

The agriculture sector provides the majority of food supplies, ensures security, and promotes sustainable development. Due to recent climate changes as well trends in human population growth environmental degradation, need for timely agricultural information continues rise. This study analyzes predicts impacts change on security (FS). For 2002-2021, Landsat, MODIS satellite images predisposing variables (land surface temperature (LST), evapotranspiration, precipitation, sunny days, cloud ratio, soil salinity, moisture, groundwater quality, types, digital elevation model, slope, aspect) were used. First, we used a deep learning convolutional neural network (DL-CNN) based Google Earth Engine (GEE) detect land (AL). A remote sensing-based approach combined with analytical process (ANP) model was identify frost-affected areas. We then analyzed relationship between climatic, geospatial, topographical AL found negative correlations - 0.80, 0.58, 0.43, 0.45 LST, respectively. There is positive correlation quality 0.39, 0.25, 0.21, 0.77, areas elevation, aspect are 0.55, 0.40, 0.52, 0.35, 0.45, 0.39. Frost-affected have day, moisture 0.68, 0.23, 0.38, Our findings show that increase salinity associated decrease AL. Additionally, decreases decreasing quality. It also increase, well. Furthermore, when decrease. Finally, predicted FS threat 2030, 2040, 2050, 2060 using CA-Markov method. According results, will by 0.36% from 2030 2060. Between 2060, however, area very high about 10.64%. In sum, this accentuates critical region. proposed methods could be helpful researchers quantify different regions periods.
