Abstract |
: |
Urban infrastructure, such as bridges, roads and buildings, is
constructed from a complex mixture of construction materials
including concrete, metals, ceramics and plastics. The creation
and operation of this infrastructure requires building activities
(referring here to construction, refurbishment, demolition and
recycling) over the life cycle of individual assets. Such buildingrelated
activities are recognised as important but poorly quantified
sources of coarse particles (i.e. 10 mm, PM10). However, far less
attention has been paid to associated emissions of fine (i.e.
2.5 mm, PM2.5) and ultrafine particles (UFP; <100 nm in diameter).
In fact, it remains largely unknown whether these activities also
cause the unintended release of UFPs. As a consequence the focus
of this article is limited to the UFP fraction arising from building
activities, both due to length constraints and the lack of published
information compared with larger size fractions. This should not
distract from the fact that investigation of the release and exposure
to both the coarse and fine fractions of particles from building activities
are important and worthy of investigation. In seeking to
address this under-explored topic preliminary evidence of UFP
dust release during the processing of concrete materials is presented
and the importance of such emissions and associated exposure
discussed. The need for risk assessment and management
strategies is also examined and some of the research gaps highlighted.
The term ‘UFP dust’ is used throughout this article to refer
to the UFP produced from the building activities to make them
distinct from those arising from combustion or other engineering
processes (Kumar et al., 2010). |
