Municipal waste landfill as a source of polychlorinated biphenyls releases to the environment

Abstract

This study aimed to investigate the impact of municipal waste landfill on polychlorinated biphenyls (PCBs) release to the environment concerning groundwater flow directions. The contents of polychlorinated biphenyls in soils, plants and water were analysed at various distances from the landfill. Thanks to low solubility PCBs in water groundwater flow direction, under the landfill, have an influence on PCBs concentration in groundwater. Strong PCBs’ sorption to organic matter caused that no affect groundwater flow directions on PCB content in soils and plants’ tissues was observed. The largest PCBs deposition zone was located 50 m from the contamination source (landfill). Tri-CB and tetra-CB homologues were capable of migration deep into the soil profile, which could be related to the geological material from which the soils under study were developed, as well as to the properties of the PCB homologues.

Networks of placental DNA methylation correlate with maternal serum PCB concentrations and child neurodevelopment

“…Prior to their international ban in 2001 ( Stockholm Convention, 2001 ), PCBs were commonly used in industrial processes and consumer products, such as plastics, paint, and pesticides. Over 20 years later, PCBs continue to be released into the environment from spills/improper disposal, degradation of PCB-containing materials, and inadvertent production ( Grimm et al, 2015 ; Hu and Hornbuckle, 2010 ), resulting in their presence throughout our environment, from oceans ( Wagner et al, 2019 ), soil (reviewed in ( Wolska et al, 2014 )) and landfills (reviewed in ( Gabryszewska and Gworek, 2021 ), to human food products ( Saktrakulkla et al, 2020 ) and indoor air, including air in schools (reviewed in ( Herrick et al, 2016 )). PCBs are detectable and persistent in many marine (reviewed in ( Domingo and Bocio, 2007 )) and land animal species (reviewed in ( Rhind, 2002 )), as well as in humans, including pregnant people ( Granillo et al, 2019 ) and newborns ( Berghuis et al, 2013 ; Mori et al, 2014 ; Yu et al, 2019 ).…”

Assessment of the Levels of Persistent Organic Pollutants in the Ghabawi Landfill in Jordan

“…In most nations, trash landfilling is the most common method of Municipal Solid Waste (MSW) disposal. Polychlorinated biphenyls (PCBs) and pesticides, for example, might be found in landfills (Gabryszewska and Gwore., 2021, Lou et al, 2016and Melnyk et al, 2015. Jordan, like many other countries in the world, witnessed an increasing population (11 million, with a 2.6% of growth rate) and consistent developments, particularly in main cities such as Amman, Irbid, and Zarqa (Greater Amman Municipality, 2018).…”
