Environmentally Persistent Free Radicals as Sources of POPs

Received: 17 January 2021;  Published: 13 May 2021;  doi: 10.21926/aeer.2102010

Abstract

Environmentally persistent free radicals (EPFRs) are a new class organic pollutant sharing some of the attributes of persistent organic pollutants (POPs). This opinion/short review aims to describe the properties of EPFRs that merit their recognition as an additional and potentially significant source of POPs. EPFRs are ubiquitous in diverse environments because of multiple factors: (1) organic precursors from anthropogenic, biogenic, and other natural emission sources are abundant; multiple mechanisms in PM and so [...]

Gender-Dependent Effects of Endocrine Disrupting Chemicals on Retinoic Acid-Related Orphan Receptor Alpha [RORA] and Aromatase Genes on Human Progenitor Neurons

Received: 28 August 2020;  Published: 07 May 2021;  doi: 10.21926/aeer.2102009

Abstract

Normally we encounter a myriad of chemicals in our daily lives. Endocrine disrupting chemicals [EDCs] are ubiquitous in our environment and upon bodily entry many be stored in adipose tissue and, in pregnant woman, can reach the developing fetal brain, disrupting normal fetal brain development. EDC-induced aberrant levels of sex hormones can alter sexual dimorphism [i.e. degree of feminization or masculinization; sex differences in brain and behavior] and may contribute to the differential susceptibility of males a [...]

A Neural Network Evidence of the Nexus Among Air Pollution, Economic Growth, and COVID-19 Deaths in the Hubei Area

Received: 19 February 2021;  Published: 06 May 2021;  doi: 10.21926/aeer.2102008

Abstract

In this study, we used an image neural network model to assess the relationship between economic growth, pollution (PM2.5, PM10, and CO2), and deaths from COVID-19 in the Hubei area (China). Data analysis, neural network analysis, and deep learning experiments were carried out to assess the relationship among COVID-19 deaths, air pollution, and economic growth in China (Hubei province, the epicenter of the COVID-19 pandemic). We collected daily data at a city level from January 20 to July 31, 2020. We used main cit [...]

Concentrations of Gaseous Elemental Mercury in the Atmosphere of a Mediterranean Coastal Site in Greece

Received: 25 January 2021;  Published: 04 May 2021;  doi: 10.21926/aeer.2102007

Abstract

Gaseous elemental mercury (GEM) was monitored in the atmosphere of a coastal site situated in the Northern Aegean Sea of Greece from August 2014 to January 2015. The selected sampling site is seldom impacted by human activities. Thus, it was possible to study the processes involved in natural terrestrial, aquatic, and atmospheric environments. The diurnal and monthly variations in the concentration of GEM as well as the factors influencing these variations were determined. The GEM concentrations were found to be in [...]

Challenges in the PFAS Remediation of Soil and Landfill Leachate: A Review

Received: 15 December 2020;  Published: 19 April 2021;  doi: 10.21926/aeer.2102006

Abstract

The use of per-and poly-fluoroalkyl substances (PFAS) has resulted in the contamination of different environmental matrices. In EU countries, the sites contaminated with PFAS are usually remediated by excavating the soil and disposing of it in a landfill, as no in-situ or on-site techniques capable of treating large quantities of soil cost-effectively have been developed. Landfilling of PFAS-contaminated soil is one of the sources of PFAS in landfill leachate. In this paper, the physical and chemical treatment meth [...]

Initial Validation of a Replicated Field-scale Denitrifying Bioreactor Facility in a Boreal Environment

Received: 29 December 2020;  Published: 15 April 2021;  doi: 10.21926/aeer.2102005

Abstract

Denitrifying bioreactor technology, where a solid carbon source (woodchips) acts as a reactive medium to intercept agricultural tile drainage water, has been successfully used to convert N (NO3-) to di-nitrogen (N2) gas. Four replicated field-scale (24 m long × 3 m wide × 1 m deep), bioreactors were built and operated at the St. John's Research and Development Centre and were successful at removing a notable amount of nitrate (N) from agricultural subsurface drainage water. The objective of this study [...]

Evolution of Radar and Lightning Variables in Convective Events in Barcelona and Surroundings for the Period 2006–2020

Received: 28 October 2020;  Published: 14 April 2021;  doi: 10.21926/aeer.2102004

Abstract

The Metropolitan Area of Barcelona is a densely populated region in the North-East of the Iberian Peninsula. Infrastructures in this area play a significant role in the economy of this part of Europe. The combination of the Mediterranean Sea and the complex topography is responsible for the occurrence of severe weather events in this location and the surrounding areas. The use of remote sensing data in an hourly resolution allows the identification and characterization of those severe episodes, helping in determini [...]

Linking Population and Forest Dynamics over the Conterminous US for the 1990s and 2000s

Received: 24 September 2020;  Published: 09 March 2021;  doi: 10.21926/aeer.2101003

Abstract

Few studies have investigated deforestation and population connections in the U.S. at large spatial extents or small scales. We examined forest cover changes over two decades, 1990-2000 and 2000-2010, in the continental U.S. at the county scale. Forest dynamics were estimated using the National Land Cover Database, a satellite-derived classification product and then linked to population data from the US. Census. At the aggregate level, high population growth seems to increase net forest loss in a non-linear manner, [...]

Impact of Covid-19 Pandemic on Air Transport: Overview and Implications

Received: 16 December 2020;  Published: 22 February 2021;  doi: 10.21926/aeer.2101002

Abstract

The current situation of the COVID-19 pandemic has led to multiple changes in the international market as well as in the lifestyle of people worldwide. The transport sector has undoubtedly been one of the most affected sectors due to restrictions imposed by the governments across the world to protect the health of their citizens, particularly the restrictions imposed on the operation of airlines. On the other hand, the reduction in travel by means of transport has contributed in part to the improvement in the envir [...]
