中文摘要
评估个人暴露在空气中颗粒物的空间和时间变化
代表关键本地来源的组件,如柴油交通,对于推进我们的
了解城市空气污染对健康的影响。目前的暴露评估方法也是
繁琐、嘈杂和劳动密集型,不能提供关键分析物的近实时测量。
我们建议开发和测试一种微型(手掌大小)、安静、可充电的个人采样器,它将
(1)记录近实时、时间和空间分辨率的黑碳(BC)浓度,(2)收集和
存档时间和空间分辨率的PM样本以供以后的实验室分析,(3)有一个额外的通道
用于相关气体或蒸气的化学光学分析,如臭氧,以及(4)测井位置和活度
数据。我们在尺寸、功率、成本和安静方面的设计目标将允许在大多数个人上广泛使用,包括
幼儿,不中断正常活动。BC将通过内部微型机测量
沉积颗粒的光学吸附分析。空间信息将由一个微型全球
室外位置的位置传感器(GPS)和室内关键位置的小型家庭/工作/车载无线信标
地点。该单位将存档多个时间和空间分辨的颗粒物样本,供实验室通过
质谱学和单粒子技术,以确定接触辐射的时空模式
粒子来源和广泛的痕量金属。可编程的微型“智能”个人

英文摘要
Assessing spatial and temporal variations in individual exposures to airborne particulate matter
components that are representative of key local sources like diesel traffic is critical for advancing our
understanding of the health effects of urban air pollution. Current methods of exposure assessment are too
cumbersome, noisy and labor-intensive, and do not provide near-real time measurements of key analytes.
We propose to develop and test a miniature (palm size), quiet, rechargeable personal sampler that will
(1) log in near real-time, time- and space-resolved concentrations of black carbon (BC), (2) collect and
archive time- and space-resolved PM samples for later laboratory analysis, (3) have one additional channel
for use in chemo-optical analysis of a relevant gas or vapor, such as ozone, and (4) log location and activity
data. Our design goals for size, power, cost and quietness will permit wide use on most individuals, including
young children, without disruption of normal activities. BC will be measured via an internal subminiature
optical adsorption analysis of deposited particles. Spatial information will be provided by a miniature global
position sensor (GPS) for outdoor locations and small home-/work-/car- placed radio beacons for key indoor
locations. The unit will archive multiple time- and space-resolved particulate samples, for lab analysis via
mass spectrometric and single particle techniques, to identify temporal-spatial patterns of exposure to
particle sources and to a wide range of trace metals. The programmable miniature "smart" personal
monitoring system will have the flexibility to be used in a wide range of sampling designs to assess spatial
and temporal patterns of expsoure. Development milestones will include designing, building and testing 3
progressively more advanced versions of the sampler. Version 1 will integrate a GPS sensor, but will lack
real-time BC capabilities. Version 2 will incorporate a sampling wheel and otpics to allow near real-time
measurements of BC and will include development of a base unit that will operate as a battery re-charger
and wireless data teleport, permitting continuous monitoring for up to a month without maintenance. To
assess subject compliance, a button-size compliance/location sensor will also be built and tested at this
stage. In Version 3 we will test the concept of incorporating ozone detection in near real-time on the third
channel,. Solar powered and/or large-battery-powered base units will also be designed for use in settings
where access to the power grid is limited, such as in developing countries or for use at fixed-site outdoor
locations lacking power. Laboratory and field experiments will be carried out iteratively during development
to generate sensor algorithms, find improvements as well as estimate precision and accuracy via
comparison to traditional real-time and integrative sampling methods of PM. The final smart air pollution
monitor will incorporate upgrades suggested by the latest field-testing.
