“…Although few studies have been conducted on terrestrial macroinvertebrates, increased survival has been observed in the majority of tests on aquatic macroinvertebrates following exposure to activated carbon amendments compared with exposure to untreated contaminated sediments (CH2M Hill, 2020; Harwood et al, 2022; Janssen & Beckingham, 2013). For example, increased survival following carbon amendments to untreated sediment was observed for the mussel Mytilus edulis , and for the detritivores A. aquaticus and G. pulex (Janssen & Beckingham, 2013; Kupryianchyk et al, 2011).…”

“…Due to the presence of hydrophobic organic contaminants in the environment, an important avenue of research is the remediation of pollutants by carbon sorbents (Duarte et al, 2018; Harwood et al, 2022; Janssen & Beckingham, 2013). In carbon sequestration, hydrophobic organic contaminants adsorb to the sequestering agent with the goal of reducing their bioavailability (Cho et al, 2007; Fagervold et al, 2010; Harwood et al, 2022; Janssen & Beckingham, 2013; Rakowska et al, 2012). One type of carbon sorbent, activated carbon, is widely applicable as an adsorbent in pollution control (Abel & Akkanen, 2019; Belhachemi, 2021; Cho et al, 2007; Fagervold et al, 2010; Ghosh et al, 2011; Harwood et al, 2022; Patmont et al, 2015; Payne et al, 2019; Rakowska et al, 2012).…”

“…Activated carbon amendments are also a promising method of remediation for soils and sediments contaminated with hydrophobic organic pollutants (Abel & Akkanen, 2019; Cho et al, 2007; Cornelissen et al, 2011; Fagervold et al, 2010; Ghosh et al, 2011; Harwood et al, 2022; Patmont et al, 2015; Payne et al, 2019; Rakowska et al, 2012; Rämo et al, 2022). In terrestrial habitats, activated carbon is most often applied directly to the surface of the soil and acts as a sink for organic contaminants (Hilber et al, 2009; Jonker & Smedes, 2000; Koelmans et al, 2006; Pignatello & Xing, 1995).…”

Because granular activated carbon can sequester organic pollutants, a potential strategy for reducing the bioavailability of organic contaminants in soil is through its application to the soil's surface. It is well understood that activated carbon is effective in the remediation of air, water, sediment, and soil, but less information is available on the potential toxicity of activated carbon to native wildlife following in situ remedial applications. Several studies have evaluated the effects of activated carbon on aquatic species; however, less is known about its toxicity to terrestrial species. The present study aimed to evaluate the potential lethal and sublethal effects of activated carbon on adult and juvenile Eisenia fetida, which are earthworms in the family Lumbricidae. The percentage of mortality, initial weight, and pre-and postdepuration weights of the worms were observed following exposure to a range of activated carbon concentrations, from 0.5% to 10% based on the soil's wet weight. These concentrations exceeded the 2%-4% activated carbon typically applied in the field. Activated carbon had no statistically significant effects on E. fetida survival; however, significant although inconsistent effects were observed on earthworm biomass. Although some statistical significance in biomass was observed, the biological significance of these effects is unclear. Overall, the concentrations of activated carbon applied in the field for soil remediation are unlikely to impact earthworm survival, although further testing, specifically on potential sublethal toxic effects, is required.

“…The second limitation was related to the fact that we have focused on carbon emission as a footprint for measuring global warming; future studies should also include other measures such as the air quality (PM2.5, PM10) associated with IoT sensors [97,98]. Third, our comparative study was limited to Canada and the United Kingdom, many other examples of successful case studies can be used to highlight pits and falls of sustainable development on a regional basis [99,100]. Fourth, the study did not include social media content analysis and its effects on tackling global warming issues.…”

This study investigates the role of information and communication technology (ICT), political instability and violence, and international protocols on global carbon emissions. Our empirical analysis used archival data for 146 economies from 1996 to 2019. The study’s estimates are also based on subsamples from the Organization for Economic Co-operation and Development member countries. The study found that ICT has statistically significant impacts on reducing CO2 emissions globally, but the extension of the impact for OECD member countries is considerably more substantial. Therefore, the subject of study is considered to be among the first few studies to measure the effects of violence and regional conflicts on global warming—a notable result for conflict regions around the world. Additionally, the authors narrowed down the findings to a micro level and conducted a comparative study between Canada and the United Kingdom to evaluate the countries’ performances concerning climate mitigation initiatives.
