“…Although microplastic uptake by fish is likely affected by MPs abundance, this correlation seems not to be strictly dependent on MPs abundance in water or sediments. Several studies demonstrated that higher MPs environmental concentration does not necessarily translate into higher ingestion [71,87,106,111,121]. Other factors, in fact, can drive the ingestion of MPs, as demonstrated by laboratory experiments with zebrafish (Danio rerio) by Kim and colleagues [141], in which a higher food availability has been demonstrated to trigger an increased MPs ingestion, independently of the MPs concentration in water.…”

Microplastics (MPs) have received increasing attention in the last decade and are now considered among the most concerning emerging pollutants in natural environments. Here, the current knowledge on microplastic ingestion by wild freshwater fish is reviewed with a focus on the identification of possible factors leading to the ingestion of MPs and the consequences on fish health. Within the literature, 257 species of freshwater fishes from 32 countries have been documented to ingest MPs. MPs ingestion was found to increase with rising level of urbanization, although a direct correlation with MPs concentration in the surrounding water has not been identified. MPs ingestion was detected in all the published articles, with MPs presence in more than 50% of the specimens analyzed in one study out of two. Together with the digestive tract, MPs were also found in the gills, and there is evidence that MPs can translocate to different tissues of the organism. Strong evidence, therefore, exists that MPs may represent a serious risk for ecosystems, and are a direct danger for human health. Moreover, toxicological effects have also been highlighted in wild catches, demonstrating the importance of this problem and suggesting the need for laboratory experiments more representative of the environmental situation.

“…In sh samples, the overall relative abundance of MPs followed a similar trend as in the surface water, and prominent size MPs were dominant (43%), followed by small size MPs (29%) and medium-sized MPs (28%). MPs with sizes up to 1000 µm reported being highest (70.5%) in a study by Sun et al (2020), whereas Wang et al (2020) reported that 80% of the detected MPs belonged to the size range of 500-1000 µm. The relative proportion of ingested MPs sizes also varied according to the sh feeding habit.…”

“…Recently, Kuśmierek and Popiolek, (2020) described the similar trend of the highest proportion of bres (99.8%) in the gastrointestinal tract of freshwater sh. Zhang et al (2020 b) and Wang et al (2020) also reported that the bres with the highest concentration in native freshwater sh belonging to different trophic levels from Pearl River South China. The possible reason for the highest proportion of bres in sh species may be its di culty to excrete with faeces as bres stick with intestinal walls rmly compared to other shape MPs.…”

Microplastics (MPs) are cosmopolitan in distribution and an emerging threat to life and the environment. These particles are not restricted to human-inhabited lands but also found in different mountains and glaciers where the human population is relatively low. These MPs make their way to the river ecosystem from glaciers, rains, and municipal and industrial effluents. The current study was designed to highlight MPs' pollution in water, sediments, and fishes of the Swat River: originating from the Hindu Kush Mountain Range. These samples were collected from eight different sites across the river. The average MPs concentrations were 305.79 ± 289.66 MPs/m 3, 588.29 ± 253.95 MPs/kg, and 12.54 ± 8.02 MPs/individual the water, sediments, and fish samples, respectively. The highest MPs concentrations (753.71 ± 330.08 MPs/m 3 ) in water were recorded near Mingora City, whereas MPs concentrations (834.0 ± 367.21 MPs/kg) were the highest on the same site. Among the selected fish species, the highest number of MPs was observed in Shizothorax plagiostomus. In contrast, the lowest in Wallago attu being 17.08 ± 8.27 Among the selected fish species, the highest number of MPs was observed in Shizothorax plagiostomus, whereas the lowest in Wallago attu being 17.08 ± 8.27 MPs/individual and 5.0 ± 2.36 MPs/individual, respectively. Fibres were the most prevalent MPs in all the matrices representing 80%, 92%, and 85% of the total MPs count in water, sediments, and fish samples. These findings highlighted that the high concentration of MPs prevailing in the river originating from high-altitude freshwater sources and awareness, education, ecotourism, sustainable reduction in plastic use, and strict rules and regulations could be helpful to prevent the anthropogenic menace.

“…The protection of the Songhua River and the Huai River requires substantial investment to improve clean water availability from them since they are part of the top seven important rivers in China. According to Wang (Wang, Zhang et al 2020) both the quantity of poor water (Grade V+) in both the Huai and Songhua Rivers reached 2.8% and Hua 0.6% respectively. However, the two rivers have not been able to improve on the percentage of Grade 1-III levels to the estimated 70% in the Ten Water Target.…”

“…In 2019, a total of 2.5 million tons of pollutants were removed from the river. Over a period the water colour in the towns and villages in its vicinity had changed from white to a shade of orange as a results of the impact of different forms of varying industrial e uent (Wang, Zhang et al 2020). According to the Guangdong provincial administration, an accumulated amount of 120 billion RMB (about 16.9 billion U.S. dollars) were invested into the pollution treatment of these heavily-polluted rivers in Shenzhen and to enhance the landscape enhancement of its surrounding areas (Guo, Chen et al 2020).…”

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.
