“…RQ values ≥ 1 indicate the possibility of risk if the compound is ingested by drinking water consumption considering a lifelong exposure, while for RQ values ≤ 0.2 the risk for adverse human health effects is negligibly low [9,33]. Since in the majority of the samples more than two compounds occurred, a mixed health Risk Quotient (RQ mix ) was calculated as a sum of individual RQs taking into account the Concentration Addition (CA) concept, as proposed by Qin et al [37].…”

“…However, since toxicological data of mixtures are limited, in this study we calculated the RQ of the mixtures as a sum of the individual RQs of the detected compounds according to the concentration addition (CA) concept [51]. This concept is widely used for calculating the combined risks of exposure and it assumes that the different compounds in the mixture will not interact among them, since they share the same mechanism of action and the same toxicity target [25,37]. All the components in a mixture contribute to the total toxicity depending on their concentration, resulting to the expectation that even if the individual compounds do not pose a risk, the mixture could pose it due to the addition effect [25].…”

“…This assumption was confirmed by the results of this study, that showed a risk of the combined exposure higher than the individual, but negligibly low as well (lower than 0.2). Although only some PhACs were taken into account in this study, usually a larger number of pollutants exists in the aquatic environment-even in trace levels-highlighting the fact that the mixture risk assessment is incomplete and further research is needed in order to find new ways of estimating it [37,44].…”

Pharmaceuticals and hormones (PhACs) enter the aquatic environment in multiple ways, posing potential adverse effects on non-target organisms. They have been widely detected in drinking water sources, challenging water companies to reassure good quality drinking water. The aim of this study was to evaluate the concentration of sixteen PhACs in both raw and treated drinking water sources in the Metropolitan Area of Turin—where Società Metropolitana Acque Torino (SMAT) is the company in charge of the water cycle management—and evaluate the potential human health risks associated to these compounds. Multivariate spatial statistical analysis techniques were used in order to characterize the areas at higher risk of pollution, taking into account the already existing SMAT sampling points’ network. Health risks were assessed considering average detected concentrations and provisional guideline values for individual compounds as well as their combined mixture. As reported in the just-issued Drinking Water Directive 2020/2184/UE, in order to establish priority substances, a risk assessment of contaminants present in raw drinking water sources is required for monitoring, identifying potential health risks and, if necessary, managing their removal. The results showed negligibly low human health risks in both raw water sources and treated water.

Despite the positive effect of industrialization on health and quality of life indicators across the globe, it is also responsible for the release of chemical toxins into the environment and has nurtured numerous environmental disasters with severe health effects. China alone produces more than a third of carbon emissions in the world and currently has the second highest number of pollution-related deaths, after India. There is no issue that underscores the challenges of environmental crisis in China than the gradual acceptance of the existence of the cancer villages. These are entire towns that have been completely written off as so polluted that simply living there is synonymous with high rate of cancer risk. For years, residents and advocacy groups in villages such as Wuli, Yanglingang, Yangqiao and additional 459 identified cancer villages have waged a desperate war to turn the attention of government to the high risk of stomach, liver, kidney and colon cancer in these areas located near heavy industrial complexes. China responded by promoting an ecological civilization and a beautiful China dream as its sustainability blueprint in 2012. Today, this blueprint has been engraved into the national ideology for socio-economic and political orientation. This review therefore revisits the progress made towards environmental health targets under China’s sustainable development strategy. The study systematic explores the extant works on air and water pollution since the “Ecological Civilization and the Beautiful China” Dream.

“…The Huixian karst wetland is considered as the largest karst wetland in South China (Cai et al, 2009;Chen et al, 2020;Pan et al, 2020) and has been listed as a national wetland park since 2012. This wetland has crucial ecological functions with respect to the Li River, including flood control, water purification, and biodiversity support (Qin et al, 2020). Because of its significant social-ecological value to nearby regions, many recent studies have reported on the hydrology (Pan et al, 2020), soil properties (Li et al, 2017b), contamination (Chen et al, 2020;Huang et al, 2020), and microalgal and bacterial communities (Yan et al, 2020) of the Huixian karst wetland.…”

Influence of Environmental Factors on the Variability of Archaeal Communities in a Karst Wetland

et al. 2021

Archaea are ubiquitous and play an important role in elemental cycles in Earth’s biosphere; but little is known about their diversity, distribution, abundance, and impact in karst environments. The present study investigated the effect of environmental factors on the variability of archaeal communities in the sediment of the Huixian karst wetland, the largest karst wetland in South China. Sediment cores were obtained from four sampling sites with different water depths and macrophyte inhabitants in both the winter of 2016 and the summer of 2018. The community analysis was based on PacBio sequencing and quantitative PCR of the archaeal 16S rRNA gene. The results showed that Euryarchaeota (57.4%) and Bathyarchaeota (38.7%) were dominant in all the samples. Methanogenic Methanosarcinales (25.1%) and Methanomicrobiales (13.7%), and methanotrophic archaea ANME-2d (9.0%) were the dominant Euryarchaeota; MCG-11 (16.5%), MCG-6 (9.1%), and MCG-5b (5.5%) were the dominant Bathyarchaeota. The community composition remained stable between summer and winter, and the vertical distributions of the archaeal phyla conformed to two patterns among the four sampling sites. In the winter samples, the archaeal 16S rRNA gene abundance was approximately 1.0E+10 copies/g of wet sediment and the Shannon index was 7.3±5, which were significantly higher than in the summer samples and in other karst environments. A correlation analysis showed that the moisture content and pH were the factors that mostly affected the archaeal communities. The prevalence of nitrate in the summer may be a key factor causing a significant decrease in archaeal abundance and diversity. Two features specific to karst environments, calcium-richness and weak alkalescence of the water supplies, may benefit the prevalence of bathyarchaeotal subgroups MCG-11, MCG-5b, and MCG-6. These results suggest that in karst wetlands, most of the archaea belong to clades that have significant roles in carbon turnover; their composition remains stable, but their abundance and diversity vary significantly from season to season.
