Hans Peter Arp is an Expert Advisor at the Norwegian Geotechnical Institute (NGI), Oslo and a Professor in the Department of Chemistry at the Norwegian University of Science and Technology (NTNU), Trondheim.
His research is focussed on both fundamental and applied aspects related to the fate, behaviour and transport of chemicals and plastic in the environment. His recent projects study fate of chemicals during diverse waste handling process, within the context of best management practices for hazardous chemicals within a circular economy. Many of his current research focusses towards safe and sustainable recycling of sludge, plastics and e-waste. Since 2016 he has conducted two large research projects for the German Environment Agency (UBA) to assist in the development and implementation of criteria and guidance to identify substances that are persistent, mobile and toxic (PMT) or very persistent and very mobile (vPvM). Recently a version of this criteria was adopted by the European Commission. This work is now being followed by ZeroPM, a EU Green Deal H2020 project, which he is the co-coordinator of. ZeroPM’s mandate is to enable the EU Green Deal’s ambition towards zero pollution of persistent and mobile substances, including PFAS, by developing and interlinking prevention, prioritization and removal strategies.
报告摘要
Water worldwide is becoming increasingly contaminated with substances considered persistent, mobile and toxic (PMT) or very persistent and very mobile (vPvM). PMT/vPvM substances are those which do not breakdown easily in the environment (persistent), are transported relatively rapidly through soil and groundwater (mobile) and are in some cases toxic. Their accumulation in freshwater resources is increasingly putting drinking water resources under a new type of stress. Their irreversible accumulation in the environment allows them to fulfil the criteria of a planetary boundary threat. Well known examples include melamine, 1,4-dioxane, trifluoroacetate and several PFAS, but there are many more, including a large portion of transformation products that remain unidentified. Advanced water treatment methods like ozonation or activated carbon filtration are often ineffective, forcing some water producers to invest in nanofiltration and reverse osmosis. Industry, regulators, academia, and the water sector are now acting to reduce pollution from PMT/vPvM substances. A focal point of this action is the European Union’s Green Deal, particularly its Chemicals Strategy for Sustainability towards a Toxic Free Environment and its Zero Pollution ambition. Building off an initiative by the German Environment Agency (UBA), new hazard classes for PMT/vPvM substances are currently being implemented in two of the main European chemical regulations, CLP and REACH.
The presentation will be divided into three parts, showing 1) the history of the increasing menace of PMT/vPvM substance contamination; 2) the regulatory developments related to defining PMT/vPvM substances; 3) how to confront and minimize the threat of PMT/vPvM substances. The presentation will focus on how industry, regulators, academia and the water sector can work together towards zero pollution of PMT/vPvM substances, ensuring safe, sustainable and clean water resources for future generations.
