The exposure of 15 subjects to NO2 was assessed using different approaches: (a) direct measurement of personal exposure, (b) calculation of weighted average exposure using data on time spent and concentrations measured at home, at work, in transit, and outdoors, (c) the same calculation but instead of actual concentrations, using concentrations measured in other homes in Zagreb (out of 90) situated in a district with a similar traffic density, and using the same cooking fuel. The best agreement with personal exposure was obtained for exposure under (b), but calculation with surrogate concentrations (c) also gave a fair approximation.
采用不同方法评估了15名受试者对二氧化氮的暴露情况：(a) 直接测量个人暴露；(b) 利用在家、工作场所、出行途中及户外的停留时间和测量浓度数据计算加权平均暴露；(c) 同样的计算方法，但使用萨格勒布其他90户位于交通密度相似地区且使用相同烹饪燃料的家庭所测量的浓度，而非实际浓度。(b)情况下的暴露与个人暴露的一致性最佳，但使用替代浓度进行计算(c)也能给出合理近似值。
