Occurrence and ecological risk assessment of 22 emerging contaminants in the Jilin Songhua River (Northeast China)

Abstract

Rivers may receive pharmaceuticals, personal care products, and environment estrogens, which are emerging concerns, from various sources. Understanding the fate of these emerging contaminants (ECs) from the sources to their receiving river is important for assessing their ecosystem risk. Here, the occurrence, seasonal variation, spatial distribution, and ecological risk of 22 ECs in water and sediments from the Jilin Songhua River, as well as in the effluents from the riverside Jilin wastewater treatment plant (WWTP) were investigated. Results indicated that estriol with the highest median concentration of 21.5 ng L in the river water and with the highest median concentration of 481.5 ng g in the sediments, and methylparaben with the highest concentration of 29.6 ± 2.9 ng L in the WWTP effluents were the predominant contaminants. The total concentration of ECs in the river water in the dry season was about 1.5 times higher than that in the wet season. The concentrations of these ECs close to the contaminated tributary and the WWTP were relatively high. Risk assessment showed that the maximum risk quotient value of estrone was 1.07 in the river water and estriol was 2.10 in the effluents. In addition, erythromycin posed generally medium risk in the river water and WWTP effluents. It should be paid attention to the prior control of the three contaminants in the river region.

Occurrence, Distribution, and Ecological Risk Assessment of Antibiotics in Different Environmental Media in Anqing, Anhui Province, China

“…As can be seen in Table 5, QNs and TCs antibiotics in river sediments (such as: Hai Rive [18], Liao River [36]) were almost two to three orders of magnitude higher than those in Anqing. It was also noticed that antibiotics in sediment in Anqing were slightly lower than those in the Songhua River [35] and Yellow River [38], whereas TCs in sediment in Anqing were slightly higher than those in Taihu Lake [40]. In addition, the residues in soil in Anqing were lower almost an order of magnitude than those in four provinces of China (Hebei, Henan, Sichuan, Jiangsu) [41].…”

Nano-based adsorbent and photocatalyst use for pharmaceutical contaminant removal during indirect potable water reuse

“…From the Ganges River Basin in India to the surface water in Milan, contaminants such as pharmaceuticals and personal care products have been detected. [1][2][3][4][5][6][7][8][9] These contaminants are difficult to remove and can cause harm not only to humans but to wildlife and local ecosystems as well. Pharmaceuticals, personal care products, persistent organic pollutants, methanesulfonic acids, artificial sweeteners, transformation products, and engineered nanomaterials have all been identified as current contaminants of emerging concern (CECs).…”

Occurrence of veterinary antibiotics in arable soil with different fertilisation modes: a field study

“…In addition, antibiotics and their metabolites have been excreted into various environments along with sewage, sludge or manure of hospitals and farms (Kumar et al 2012). Numerous studies reported that antibiotics had been detected in different environmental mediums, such as animal manure (Martínez-Carballo et al 2007;Hu et al 2010;Hou et al 2015;Guo et al 2016;Pan and Chu 2018;Zhou et al 2020), sewage treatment plants (Wu et al 2016), water (Zhang et al 2015;He et al 2018;Liu et al 2018), soil (Hu et al 2010;Li et al 2015;Guo et al 2016;Tasho and Cho 2016;Sun et al 2017), and even in groundwater (Hu et al 2010;Ma et al 2015). China is one of the largest producers and consumers of antibiotics.…”
