With increased urbanization and industrialization, the global burden of anthropogenic emissions through biomass and fossil fuel combustion has increased significantly, threatening the global climate system, air quality and human health. Half of the aerosol particles emitted as a result of combustion are in the form of black carbon (BC), co-emitted with polycyclic aromatic hydrocarbons (PAHs). Due to strong sorption efficiency, BC act as a carrier for highly toxic and carcinogenic PAHs in air, water and soil, causing serious health issues. Scientific literature shows that the global burden of diseases has increased due to the high pollution levels of these pollutants in the environment. BC in association with PAHs can pose acute and chronic health problems such as respiratory problems, acute bronchitis, heart problems, lung cancer, aggravation of preexisting heart and lung disease, and asthma. In addition, most of the PAHs released into the environment, due to combustion activities, are categorized as type 2A or 2B human carcinogens by US EPA. In light of environmental significance of BC associated PAHs, this article stipulated a critical overview regarding the properties, pollution sources and worldwide pollution status of BC and associated PAHs along with the health risk these pollutants can pose.

Environmental sustainability assessment using dynamic Autoregressive-Distributed Lag simulations-Nexus between greenhouse gas emissions, biomass energy, food and economic growth Sarkodie, Samuel Asumadu; Strezov, Vladimir; Weldekidan, Haftom; Asamoah, Ernest Frimpong; Owusu, Phebe Asantewaa; Doyi, Israel Nutifafa Yawo (Elsevier BV, 2019-06-10) Increasing population demand has triggered the enhancement of food production, energy consumption and economic development, however, its impact on climate change has become a global concern. This study applied a novel environmental sustainability assessment tool using dynamic Autoregressive-Distributed Lag (ARDL) simulations for model estimation of the relationships between greenhouse gas (GHG) emissions, energy, biomass, food and economic growth for Australia using data spanning from 1970 to 2017. The stud...
Climate Change Effects on Runoff, Catchment Phosphorus Loading and Lake Ecological State, and Potential Adaptations Jeppesen, Erik; Kronvang, Brian; Meerhoff, Mariana; Sondergaard, Martin; Hansen, Kristina M.; Andersen, Hans E.; Lauridsen, Torben L.; Liboriussen, Lone; Beklioğlu, Meryem; Ozen, Arda; Olesen, Jorgen E. (Wiley, 2009-09-01) Climate change may have profound effects on phosphorus (P) transport in streams and on take eutrophication. Phosphorus loading from land to streams is expected to increase in northern temperate coastal regions due to higher winter rainfall and to a decline in warm temperate and and climates. Model results suggest a 3.3 to 16.5% increase within the next 100 yr in the P loading of Danish streams depending on soil type and region. In takes, higher eutrophication can be expected, reinforced by temperature-media...
Bioelectricity Generation From Wastewater Sludge Using Microbial Fuel Cells: A Critical Review Ömeroğlu, Seçil; Sanin, Faika Dilek (Wiley, 2016-09-01) Today, the majority of the world's energy is provided by fossil fuels. Natural energy resources soon will be consumed as a result of rising energy needs of the growing population, leading to a global energy crisis. The insecurity in the energy market also affects the global economy negatively and forces the governments to investigate renewable energy alternatives such as bioenergy. Bioenergy technologies can reduce greenhouse gas (GHG) emissions significantly and can serve to satisfy many forms of energy de...
Anaerobic co-digestion of sewage sludge and primary clarifier skimmings for increased biogas production Alanya, S.; Yılmazel Tokel, Yasemin Dilşad; Park, C.; Willis, J. L.; Keaney, J.; Kohl, P. M.; Hunt, J. A.; Duran, M. (IWA Publishing, 2013-01-01) The objective of the study was to identify the impact of co-digesting clarifier skimmings on the overall methane generation from the treatment plant and additional energy value of the increased methane production. Biogas production from co-digesting clarifier skimmings and sewage sludge in pilot-scale fed-batch mesophilic anaerobic digesters has been evaluated. The digester was fed with increasing quantities of clarifier skimmings loads: 1.5, 2.6, 3.5 and 7.0 g COD equivalent/(L.d) (COD: chemical oxygen dem...
Screening and In Situ Monitoring of Potential Petroleum Hydrocarbon Degraders in Contaminated Surface Water İçgen, Bülent (Wiley, 2017-01-01) Incomplete combustion of fossil fuels and other anthropogenic activities result in contamination of surface water by petroleum hydrocarbons. These pollutants can have severe effects on aquatic life and human health. In petroleum bioremediation, oil degrading microorganisms are utilized to remove petroleum hydrocarbons from polluted water. However, monitoring and identifying microorganisms capable of degrading petroleum hydrocarbons is very challenging. In the current study, bacteria isolated from a river al...
