Abstract
The wide occurrence of new-emerging pollutants and their potential environmental and ecological risks have recently caused great public concerns. The paper firstly put forward the severe problem. Then the possible main reasons were analyzed which might attribute to both the inefficient removal of wastewater treatment plants with conventional technology and ignorance of the monitor and control of new-emerging pollutants in the effluents. Also, the complexity and extreme high costs may also make the organizations sidestep the problem. Finally, possible strategies to deal with the problems were proposed. The upgrade of wastewater treatment plants was important and urgent.
Highlights
As the social and industrial development, more and more new-emerging organic pollutants (NEOPs), such as the pharmaceuticals and personal care products (PPCPs), were detected in natural environments [1], and have been enormously documented to be devastating to ecological biodiversity and public health [2] [3] [4] [5]
Wastewater treatment plants (WWTPs) are commonly regarded as the most important barrier to prevent the entry of pollutants into environments but they failed to play the roles in new-emerging micro-pollutants removal
Numerous studies have demonstrated that the discharge from WWTPs is one of the largest sources for new-emerging organic pollutants to natural environment [1] [3] [9] [10]
Summary
As the social and industrial development, more and more new-emerging organic pollutants (NEOPs), such as the pharmaceuticals and personal care products (PPCPs), were detected in natural environments [1], and have been enormously documented to be devastating to ecological biodiversity and public health [2] [3] [4] [5]. In 2014, World Health Organization firstly reported the causal relationships between antibiotics and severe diseases in humans and warned the public as a world crisis [6]. The constantly reported environmental risks caused by NEOPs lead to public panic and drive us to keep close eyes on their environmental behaviors and explore effective approaches to handle the problems
