Abstract
Purpose
Pharmaceutical and personal care products (PPCPs) and phosphorus are pollutants that can cause a wide array of negative environmental impacts. Phosphorus is a regulated pollutant in many industrial countries, while PPCPs are widely unregulated. Many technologies designed to remove phosphorus from wastewater can remove PPCPs, therefore the purpose of this paper is to explore the ability of these technologies to also reduce the emission of unregulated PPCPs.
Design/methodology/approach
Through meta-analysis, the authors use the PPCPs’ risk quotient (RQ) to measure and compare the effectiveness of different wastewater treatment technologies. The RQ data are then applied via a case study that uses phosphorus effluent regulations to determine the ability of the recommended technologies to also mitigate PPCPs.
Findings
The tertiary membrane bioreactor and nanofiltration processes recommended to remove phosphorus can reduce the median RQ from PPCPs by 71 and 81 percent, respectively. The ultrafiltration technology was estimated to reduce the median RQ from PPCPs by 28 percent with no cost in addition to the costs expected under the current phosphorus effluent regulations. RQ reduction is expected with a membrane bioreactor and the cost of upgrading to this technology was found to be $11.76 per capita/year.
Practical implications
The authors discuss the management implications, including watershed management, alternative PPCPs reduction strategies, and water quality trading.
Originality/value
The evaluation of the co-management of priority and emerging pollutants illuminates how the removal of regulated pollutants from wastewater could significantly reduce the emission of unregulated PPCPs.

Abstract
This article describes and clarifies the human rights of persons with disabilities in the context of detention in light of the recently adopted and already in force Convention on the Rights of Persons with Disabilities (the Convention). Focusing on the Convention, the article sheds light on the legality of certain forms of detention affecting persons with disabilities, the substantive and procedural requirements for their detention, and on their rights in relation to conditions of detention. This article also provides an account of the different treatments and practices inflicted on persons with disabilities in prisons and other institutions and assesses whether they constitute torture and ill treatment. The authors argue that the Convention on the Rights of Persons with Disabilities represents a paradigm shift that requires States to modify and adopt laws, policies and practices that fully respect the right to liberty of persons with disabilities, and their equal enjoyment of rights while in detention, including the right to be free from torture and ill treatment.
