“…Meanwhile, sediment acts as a local scale collector for environmental contaminants [14][15]. PAHs adsorbed on the sediment would be retained in sediment for a long time [16] or released into water, causing secondary pollution [17][18]. Therefore, it is quite necessary to routinely monitor concentration levels of PAHs in an aquatic environment and evaluate their potential risks [13,[19][20].…”

This work investigated the distribution, partitioning, and ecological risks of 16 polycyclic aromatic hydrocarbons (PAHs) in water and sediment of the Yinma River Basin in China in normal, wet, and dry seasons. Sixteen PAHs were analyzed in 17 paired sets of water and sediment samples collected from the study area. The concentrations of PAHs in water and sediment showed spatial-temporal variations, the concentrations in water ranged from 167.6 to 373.9 ng/L with a mean value of 227.9 ng/L in the normal season, from 186.0 to 386.9 ng/L with a mean value of 281.6 ng/L in the wet season, and ranged from 147.0 to 315.9 ng/L with an average value of 218.6 ng/L in the dry season, while concentrations in sediment varied from 895.6 to 2,518.2 ng/g with a mean value of 1,739.4 ng/g in the normal season, from 1,233.0 to 4,763.0 ng/g with a mean value of 2,122.6 ng/g in the wet season, and ranged from 914.2 to 5,678.5 ng/g with an average value of 1,943.7 ng/g in the dry season. Partitioning of PAHs in water and sediment was studied and the result showed that PAHs tend to absorb in sediment. Ecological risk assessments were conducted based on the species-sensitivity distribution (SSD) model, with results suggesting that ecological risks of individual PAHs in water and sediment were little, and the multiple congeners of PAHs in sediment from some sampling sites had ecological risks. Primary sources of 16 PAHs in water and sediment were identified with isomer ratios, and results indicated that primary sources of PAHs in water were identified as a mixture pattern of petroleum and combustion sources, and in sediment were identified as a mixture pattern of petroleum and grass, wood and coal combustion sources.

“…Organochlorine pesticides (OCPs) such as hexachlorocyclohexanes (HCHs) and dichlorodiphenyltrichloroethanes (DDTs) have been of increasing concern worldwide because of their persistence, potential for bioaccumulation, and toxicity toward nontarget organisms (Willett et al 1998;Guo et al 2014). Although the production and agricultural use of HCHs and DDTs have been banned in many countries, widespread pollution by these OCPs is still occurring in various environmental media and organisms from some countries including China, India and Columbia (Dhananjayan et al 2011;Liu et al 2013;Rojas-Squella et al 2013;Tang et al 2013;Guo et al 2014;Pan et al 2014), and high levels of OCPs in humans and animals have been reported in developing countries in recent years (Qu et al 2010;Rojas-Squella et al 2013).…”

Therefore, there is an increasing need to better understand the sources of these chemicals and assess their potential ecological risks.…”

The contamination of organochlorine pesticides (OCPs) and hexachlorobutadiene (HCBD) in soils, plants, and terrestrial fauna from a former pesticide-producing area in Southwest China was investigated. High levels of OCP residues (RHCHs and RDDTs of 3.89-13,386 and 23.3-11,186 ng g -1 dw, respectively) were found in the soils within the producing factory, indicating that the former pesticide factory brownfield site poses a high environment risk and that effective soil remediation is needed. The OCP concentrations in soils surrounding the pesticide factory were 1-2 orders of magnitude higher than in the other agricultural areas from China. Grass, vegetables, and tree leaves from the surrounding areas of the point source showed moderate OCP pollution, which was likely to be causing potential negative impacts on terrestrial ecosystem. OCP levels in terrestrial species from the studied area including insects, free-range chickens and birds were moderate, and were generally within accepted safe levels.b-HCH was the most prevalent isomer, implying that hexachlorocyclohexane (HCH) residues were mainly derived from the degradation of technical HCH. The dichlorodiphenyltrichloroethane (DDT) profiles reflected obvious degradation of technical DDT. In the study area, the concentrations of HCBD were \0.02-5.59, 0.03-24.6 ng g -1 dw and 1.65-3.80 ng g -1 lw in soils, plants, and animals, respectively, which were relatively low and not sufficient to cause observable adverse biological effects.

“…Roughly 200 vehicles worldwide emit approximately 400,000 exhaust each year, which has become the main source of this Pb pollution. Factories are also located on the roadside, even the edge of cities, to reduce transportation cost, which also causes Pb pollution [49][50][51]. Thus, Pb mainly comes from anthropogenic sources [52].…”

Source Identification and Human Health Risk of Heavy Metals in Soil: a Case Study of Industrial Areas of Northeast China

IntroductionRapid urbanization and industrialization provide benefits to the economy and society but also cause pollution of soil, water, and air and even pose risks to ecosystems [1][2][3][4]. Heavy metals refer to metals and metalloids, such as Cr, Cu, Zn, As, Cd, Ni, Pb, and Hg, whose densities are > 5 g•cm −3 [5][6]. Heavy metals in soil are difficult to degrade and enter the food chain. Consequently, heavy metal pollution will not only reduce the quality of the soil environment but also pose a threat to human health [7][8][9][10][11][12]. For instance, exposure to As can lead to dermal lesions, skin cancer, peripheral neuropathy, and peripheral vascular disease
