Passive air samplers (PAS) have been developed since the early 2000s and widely used for the atmospheric monitoring of persistent organic pollutants (POPs). PAS are useful especially for the investigation of source-receptor relationship of POPs because they provide higher spatial resolution data. In...

대기 중 잔류성유기오염물질의 환경거동을 이해하기 위해서 무엇이 필요한가? | , 2008b). POPs의 환경거동을 이해하기 위해서는 배출원-수용원 관계(Source-receptor relationship)를 파악하는 것이 우선이며, 이를 위해서는 다수 지점에서의 대기 모니터링이 필수적이다. POPs 농도는 다른 대기오염물질 농도에 비해서 매우 낮은 수준이므로(수 ng/m3), 능동대기채취기 (Active air sampler: AAS)의 일종인 고용량대기채취기(High volume air sampler: HiVol)를 이용하여 짧은 기간 (보통 12~24시간)에 많은 양의 시료(1,000m3 내외)를 채취한다. | |
대기 중 잔류성유기오염물질의 특성은 무엇인가? | 대기 중 잔류성유기오염물질(Persistent organic pollutants: POPs)은 대표적인 미량독성물질로서 생축적, 독성, 잔류성, 장거리 이동, 다매체 거동의 특성을 나타낸다 (UNEP, 2013). 유엔환경계획 (United nations environment programme: UNEP)의 스톡홀름협약 (Stockholm convention)에서 규제하는 POPs 종류에는 다이옥신류 (Polychlorinated dibenzo-p-dioxins/furans: PCDD/Fs), 유기염소계농약류 (Organochlorine pesticides: OCPs), 폴리염화비페닐 (Polychlorinated biphenyls: PCBs), 브롬화계난연제 (Brominated flame retardants: BFRs), 과불화합물(Perfluorinated chemicals: PFCs)이 있다. | |
POPs 종류에는 어떤 것들이 있는가? | 대기 중 잔류성유기오염물질(Persistent organic pollutants: POPs)은 대표적인 미량독성물질로서 생축적, 독성, 잔류성, 장거리 이동, 다매체 거동의 특성을 나타낸다 (UNEP, 2013). 유엔환경계획 (United nations environment programme: UNEP)의 스톡홀름협약 (Stockholm convention)에서 규제하는 POPs 종류에는 다이옥신류 (Polychlorinated dibenzo-p-dioxins/furans: PCDD/Fs), 유기염소계농약류 (Organochlorine pesticides: OCPs), 폴리염화비페닐 (Polychlorinated biphenyls: PCBs), 브롬화계난연제 (Brominated flame retardants: BFRs), 과불화합물(Perfluorinated chemicals: PFCs)이 있다. 또한, 대표적인 유해대기오염물질(Hazardous air pollutants: HAPs)인 다환방향족탄화수소 (Polycyclic aromatic hydrocarbons: PAHs)는 스톡홀름 협약의 규제대상물질은 아니지만, 유엔유럽경제위원회 (United nations economic commission for Europe: UNECE)의 대기오염물질 장거리이동에 관한 협약 (Convention on long-range transboundary air pollution: CLRTAP)에서 POPs로 지정되었다(UN, 2004). |
