“…The term of ECs could be referred to three main categories [ 56 ]. Firstly, substances recently released into the environment like industrial additives such as bisphenol A [ 57 , 58 ]. Secondly, chemical agents that could already have existed in the environment for several years, and only recently, their significance has begun to attract public attention, which is the case with pharmaceuticals [ 59 ], personal care products, etc.…”

Electrochemical sensors play a significant role in detecting chemical ions, molecules, and pathogens in water and other applications. These sensors are sensitive, portable, fast, inexpensive, and suitable for online and in-situ measurements compared to other methods. They can provide the detection for any compound that can undergo certain transformations within a potential window. It enables applications in multiple ion detection, mainly since these sensors are primarily non-specific. In this paper, we provide a survey of electrochemical sensors for the detection of water contaminants, i.e., pesticides, nitrate, nitrite, phosphorus, water hardeners, disinfectant, and other emergent contaminants (phenol, estrogen, gallic acid etc.). We focus on the influence of surface modification of the working electrodes by carbon nanomaterials, metallic nanostructures, imprinted polymers and evaluate the corresponding sensing performance. Especially for pesticides, which are challenging and need special care, we highlight biosensors, such as enzymatic sensors, immunobiosensor, aptasensors, and biomimetic sensors. We discuss the sensors’ overall performance, especially concerning real-sample performance and the capability for actual field application.

“…A 20 mL solution of 0.01 mol/L NaNO 3 containing varying concentrations of Pb and Cr was added to each tube. Solutions containing various concentrations (5,10,20,50, and 100 mg/L) of 20 mL Pb 2+ (Pb(NO 3 ) 2 solution) and various concentrations (5,10,20,30, and 50 mg/L) of 20 mL Cr 6+ (K 2 Cr 2 O 7 solution) were prepared.…”

“…Compared with emerging contaminants, heavy metals might pose higher risks [16][17][18]. Heavy metal pollution and emerging contaminants have attracted attention widely [19][20][21][22]. FTC is one of the critical processes that influence heavy metal behaviors through changing soilspecific surface area, organic matter content, physical structure, and other soil properties [23][24][25].…”

The freeze-thaw cycle is one of the important processes that affected heavy metal behaviors in soil. However, information regarding the adsorption and desorption behavior of heavy metals in soils under different freeze-thaw conditions is relatively less. Therefore, different freeze-thaw conditions including unfrozen, 15 freeze-thaw cycles at 60% water content, and 15 freeze-thaw cycles at 100% water content were investigated. Then the adsorption and desorption behaviors of Pb and Cr in freeze-thaw soils were studied. Results showed the Pb and Cr adsorption amount mostly decreased with increasing water-soil ratio, and the soil performance of Pb and Cr adsorption at same water-soil ratios showed variation under different freeze-thaw conditions. The Pb isothermal adsorption was higher for most freeze-thaw treatments compared to the control. The soil performance of Cr isothermal adsorption showed variation under different freeze-thaw conditions. Most electrostatic binding of Pb and Cr were stronger under unfrozen and freeze-thaw conditions than unfrozen conditions. Most Pb and Cr adsorption kinetics patterns of freeze-thaw treated soils were rapid than unfrozen conditions. These results implied that freeze-thaw cycles could change the soil adsorption and desorption patterns of Pb and Cr. Therefore, further studies are urgently needed to investigate Pb and Cr immobilization mechanisms in soils during freeze-thaw cycles. Hence, these findings provided useful information on Pb and Cr immobilization process in soils that underwent freeze-thaw cycles to offer an additional insight into predicting Pb and Cr behaviors in cold and freezing environments.

“…Concentrations of 85.15 ng L -1 , 4.72 ng L -1 ,and 64.24 ng L -1 of E1, E2 and EE2, respectively, were found in the wastewater treatment plant of the city of Chascomús, Argentina (González et al, 2020), and its presence causes endocrine disruption that can affect aquatic organisms such as inhibition of gonadal growth and suppression of spermatogenesis (S. Wang et al, 2018). as it can also have adverse effects on the human body as an endocrine disruptor (Xu et al, 2021), It is therefore important to determine and monitor these emerging pollutants in water bodies (Katrina & Espino, 2020).…”

“…There is concern about emerging pollution in many lakes, which are important sources of water, considering that lakes are sometimes watershed drains and reservoirs that are altered by changes in land use and environmental conditions (Sacdal et al, 2020). The presence of hormones in lakes such as Laguna Lake, Philippines was found to be 0.03 and 0.30 ng L -1 of E1 and 0.36 ng L -1 of EE2 (Katrina & Espino, 2020), in Buyukcekmece Lake, Istanbul Turkey from <0.5 ng L -1 to 5.74 ng L -1 of E1, <0.5 ng L -1 to 10.2 ng L -1 of E2 and <0.5 ng L -1 to 11.7 ng L -1 of EE2 (Aydin & Talinli, 2013), while in East Lake, Wuhan China, nd to 9.62 ng L -1 E1, nd to 17.26 ng L -1 E2, and nd to 6.85 ng L -1 EE2 were found (J. Wang & Zhu, 2017), Also in Honghu Lake, China an average of 17.64 of E1, 7.26 ng L -1 of E2, and 17.73 ng L -1 respectively were found, as well as in Dongting Lake, China an average of 5.63 of E1, 10.32 of E2, 3.04 of EE2, 3.04 ng L -1 of EE2 (Yang et al, 2015).Space therefore, this study reports the presence of steroid hormone residues in the waters of the inner bay of Lake Titicaca and drinking water in the city of Puno.…”

The presence of steroid hormones in lake waters causes contamination of aquatic ecosystems, which may cause endocrine alterations in the organisms that inhabit them. Moreover, many of these waters are purified and distributed to populations located around the lake. Therefore, these effects could be repeated in humans consuming the water. This study reports the presence of steroid hormone residues in the waters of the inner bay of Lake Titicaca and drinking water in the city of Puno (Peru). The solid phase extraction method was used for sample preparation, and the analyses were developed in an HPLC-DAD system. Results show maximum concentrations of steroid hormones estrone (E1) 1.56, 17 β- estradiol (E2) 2.27, 17 α- ethinylestradiol (EE2) 13. 88 ng L-1 respectively. These concentrations vary at the different monitoring points, and their presence could cause ecotoxicological effects to the endemic aquatic biota that inhabit this part of the lake. At the same time they also could affect the health of the human population that consumes this water
