Occurrence and risk assessment of pharmaceuticals and personal care products and endocrine disrupting chemicals in reclaimed water and receiving groundwater in China

Differential enzymatic degradation of thiazole pollutants by two different peroxidases – A comparative study

“…For example, it is estimated that up to 280,000 ton of synthetic dyes per year are discharged into the environment (mostly rivers and seas) [1]. In addition to these traditional sources of pollution, increased environmental awareness has highlighted concerns arising from the prevalent presence of ''emerging pollutants" or ''contaminants of emerging concern" in our water supply [2][3][4]. These emerging pollutants are broadly defined as synthetic chemicals or microbes in the environment that are normally not monitored but have the potential to adversely affect various living organisms.…”

The influence of reclaimed water recharge on 12 isomers of NP in groundwater

“…In Beijing city, 18 × 106 m 3 /y of wastewater was treated as reclaimed water from 2008 [2]. However, it is difficult to remove all the contaminants in reclaimed water completely, meaning that some of them such as endocrine disrupting chemicals, pharmaceuticals, perfluorochemicals and antibiotics were introduced into groundwater, thereby pose risks to groundwater and humans [3][4][5]. It is urgent to study the pollutants in reclaimed water and groundwater for risk assessment.…”

“…NP was a priority pollutant in the effluent of wastewater treatment plants, which had the higher ecological risk [6]. Several researchers [5,7] had studied the NP in the groundwater influenced by reclaimed water or waste water. Moreover, most of the researchers studied the NP which was the mixture of isomers and the isomers of NP in the groundwater have rarely been reported.…”

The removal of oxytetracycline (OTC) by potassium ferrate (VI) in aquatic environment

“…It is widely used in swine, cattle, poultry and fish husbandry as feed additives and veterinary drugs for prophylactic, and therapeutic purposes throughout the world, because of its low cost and effective antimicrobial (Lu et al, 2015). However, the widespread use of it has led to much environmental issues and human health problems (Marx et al, 2015;Li et al, 2015;Burkina et al, 2015;Auerbach et al, 2007;Luis Martinez, 2009), such as the presence of OTC residues in animal foods and environmental pollution (Kim et al, 2014;Fritz et al, 2007;Sun et al, 2014). Most of OTC leaves human and animal body unmetabolized via feces and urine Kemper, 2008).Therefore OTC is extensively distributed in soil, groundwater, surface water, sea water, and sediment worldwide (Shibata et al, 2014;Chen et al, 2015;Kuemmerer, 2009).…”
