Distribution and pollution sources of polycyclic aromatic hydrocarbons (PAHs) in reclaimed tidelands and tidelands of the western sea coast of South Korea

Abstract

The wide-scale reclamation of tidal flats distributed throughout the western and southern coastal areas in Korea has been completed, in an effort to expand the available arable land. The present studies were conducted in order to characterize the concentrations and compositional patterns of selected PAHs, in order to obtain more information regarding environmental risk assessments for sustainable and environment-friendly agriculture in reclaimed tidelands and tidelands in South Korea. The PAH contents were low to moderate, relative to other urbanized regions of the world. Sigma PAHs ranged from 69.8 to 1,175.2 ng g(-1) in dry weight, with a mean value of 394.4 ng g(-1). Differences were observed in the Sigma PAHs concentrations between industrial complex areas and rural regions. The two dominant PAHs were identified as fluoranthene and pyrene. These compounds constituted 1.4 to 55.0% (mean, 33.4%) and 2.7 to 45.6% (mean, 22.0%) of the Sigma PAHs. Our correlation analysis revealed that the Sigma PAHs contents were associated significantly with the organic carbon content (R(2) = 0.86, P < 0.01) and the cation exchange capacity (CEC; R(2) = 0.89, P < 0.01) in the reclaimed tidelands and tidelands.

“…Previous studies of the past have shown that air pollution directly affects lung disease and respiratory diseases in the United States in 1948, a case of air pollution in Pennsylvania, USA [5][6][7]. In Korea, it has been confirmed that the application of industrial deterrence (Yeosu, Gwangyang, Ulsan, Pohang, Ansan) has increased as a factor of cancer occurrence and disease in recent years through the process of establishing industrial complexes in major economic development since 1970 [8,9] Among them, heavy metals and chemicals in Korea are identified as air pollutants, and fine dust due to fuel consumption is also confirmed [10,11]. As a result, the emission factors of odor, air pollution, soil pollution, and heavy metals directly affect the residents of the area due to the composition of the industrial complex.…”

Pollution analysis of soil polycyclic aromatic hydrocarbons from informal electronic waste dismantling areas in Xinqiao, China

“…One is anthropogenic sources, such as the incomplete combustion of fossil fuels, e-waste and sewage sludge (Peng et al, 2011). The other is natural sources, like forest fires and volcanic eruptions (Cho et al, 2009). Their influences on human health and ecosystems are of great concern to researchers.…”
