“…CECs are a heterogeneous set of pollutants that includes pharmaceuticals, personal care products, insecticides, flame retardants, industrial additives, surfactants, plasticizers, and nanomaterials [6][7][8] Based on the current global research trends on CECs, the CECs discussed in this study can be classified as follows: POPs (Persistent Organic Pollutants), antibiotics, EDCs (Endocrine-Disrupting Chemicals), and microplastics. With the wide application of chemicals in industry, agriculture, etc., the introduction of CECs into the environment is inevitable.…”

The introduction of contaminants of emerging concern (CECs) into the environment has raised concerns due to the significant risks they pose to both ecosystems and human health. In this sys-tematic review, we investigate research trends on CECs worldwide over the past 10 years, focus-ing on four critical aspects: (i) the identification and distribution of typical CECs across various media, (ii) the sources and environmental behavior of CECs, (iii) the implications of CECs expo-sure on human health, and (iv) risk assessment and control measures for CECs. The review re-veals a comprehensive understanding of the typical types and distribution of CECs in different environmental media, shedding light on their prevalence and potential impact on ecosystems. Furthermore, insights into the sources and behavior of CECs provide crucial information for de-vising effective strategies to mitigate their release into the environment. By examining the health effects of EC exposure, we highlight the importance of considering potential risks to human well-being. This aspect of the review emphasizes the significance of monitoring and managing CECs to safeguard public health. The review also synthesizes the advancements in risk assessment methodologies and control measures for CECs, which are essential for developing comprehensive regulations and guidelines to manage these contaminants effectively. Drawing from the findings, we identify future research directions for CECs in aquatic environments.

“…Even though these contaminants are usually found at low concentrations in aquatic environments, they may produce adverse short-and long-term effects over time [19]. The effects of complex mixtures of CECs on organisms are often subtle, sublethal, and indirect [38].…”

“…Globally, poor water quality is largely determined by the level of aquatic pollution and is of great concern to public health and well-being [19]. Numerous studies have reported endocrine disruptors, pesticides, pharmaceuticals, illicit drugs, and personal care products in surface or drinking water sources [20][21][22][23][24][25].…”

“…Nonetheless, such minimum traces found in water or sediments are likely to bioaccumulate in species exposed to constant trace amounts of many different compounds. Consumption of animals exposed directly to such contaminants is becoming increasingly problematic [19]. Ojemaye and Petrik [26][27][28] reported that the levels of contaminants found in seawater, sediment, and several marine organisms (seaweed, invertebrates, and fish) may pose a threat to various trophic levels due to their high bioaccumulation factors and calculated risk quotients.…”

Approximately 9% of couples are infertile, with half of these cases relating to male factors. While many cases of male infertility are associated with genetic and lifestyle factors, approximately 30% of cases are still idiopathic. Contaminants of emerging concern (CECs) denote substances identified in the environment for the first time or detected at low concentrations during water quality analysis. Since CEC production and use have increased in recent decades, CECs are now ubiquitous in surface and groundwater. CECs are increasingly observed in human tissues, and parallel reports indicate that semen quality is continuously declining, supporting the notion that CECs may play a role in infertility. This narrative review focuses on several CECs (including pesticides and pharmaceuticals) detected in the nearshore marine environment of False Bay, Cape Town, South Africa, and deliberates their potential effects on male fertility and the offspring of exposed parents, as well as the use of spermatozoa in toxicological studies. Collective findings report that chronic in vivo exposure to pesticides, including atrazine, simazine, and chlorpyrifos, is likely to be detrimental to the reproduction of many organisms, as well as to sperm performance in vitro. Similarly, exposure to pharmaceuticals such as diclofenac and naproxen impairs sperm motility both in vivo and in vitro. These contaminants are also likely to play a key role in health and disease in offspring sired by parents exposed to CECs. On the other side of the double-edged sword, we propose that due to its sensitivity to environmental conditions, spermatozoa could be used as a bioindicator in eco- and repro-toxicology studies.

“…Throughout the last decade, several chemical contaminants (i.e., anthropogenic source), often labelled as Contaminants of Emerging Concern (CECs), such as perfluorinated compounds (PFCs), alkylphenols, pharmaceuticals and personal care products (PPCPs), pesticides, carcinogenic metals (Cd, Ni, Cr, and As), present in water have come to the attention of authorities in terms of environmental and human health risk. Uncertainties over the occurrence, origin, and hazard of CECs and the large number of all kinds of emerging pollutants have prompted authorities to take measures and impose a set of priorities concerning the maximum accepted concentrations for these environmental contaminants [ 4 , 5 , 6 , 7 ]. Discovering the sources, and understanding the interactions and effects of water pollutants is essential for monitoring contaminants in a safe environment, and in an economically acceptable manner.…”

This study is the third in a series of investigations conducted by the authors, and certainly the most comprehensive research regarding the former uranium, copper, and charcoal mines from a particular geographical area of Romania. In this respect, the present scientific incursion focused on two areas containing former extraction uranium ore sites, Ciudanovita and Lisava, as well as copper ore from Moldova Noua and charcoal mines from Anina, Banat Region, Romania. It highlighted that, for the first time, the heavy metal concentration was correlated with the values of physicochemical indicators of water (i.e., EC, DO, pH, resistivity, salinity, and ORP), by using multivariate analysis, to shape a regional based model on spatial distributions and the variability of toxic contaminants from the hydrographic basin of Banat, Romania, as a consequence of former uranium, copper, and charcoal mines. In this regard, 11 metals including Al, Cr, Mn, Fe, Ni, Co, Cu, Zn, Sr, Cd, and Pb from different water samples (well, spring, river, and lake), collected from three mining areas (uranium, copper, and coal mines) were investigated. Non-carcinogenic and carcinogenic health risks of seven heavy metals were assessed using the EDI, DIM, and THQ. The obtained THQ values were within the acceptable limits for cancer risks for adults, but as regards children, eight samples out of 18 proved toxic. However, the HRI and THQ average values for Cd (0.265 adults/0.996 children) and Pb (0.025 adults/0.095 children) for children were 3–4 times higher than those for adults. This is a source of concern as their prevalence in well water exposes children and residents in the Banat Region to the risk of various types of cancers.
