Aeroallergen sampling provides information regarding the onset, duration, and severity of the pollen season that clinicians use to guide allergen selection for skin testing and treatment.
This atmospheric survey reports: 1) airborne pollen contributors in Philadelphia, Pennsylvania (1991 to 1997) and suburban Cherry Hill, New Jersey (1995 to 1997); 2) pollen onset, duration, and peak level; and 3) the relationship between airborne pollen and selected meteorologic variables.
At both locations, separated by 11 km. sampling was performed with a volumetric Rotorod Sampler (Sampling Technologies, Minnetonka, MN).
In Philadelphia and Cherry Hill, respectively, 3-year average measurements included 75.0 and 74.2% tree pollen, 10.2 and 8.3% grass pollen, and 14.8 and 17.5% weed pollen. Prominent airborne pollen taxa were Acer, Quercus, Betula, Pinus, Cupressaceae, Poaceae, Ambrosia, and Rumex. The tree, grass, and weed pollen seasons extended from mid-March to mid-June, late April to mid-June, and mid-August to late September, respectively. A secondary Poaceae pollen peak occurred in September. There was a statistically significant correlation between simultaneous weekly average pollen levels in Philadelphia and in Cherry Hill (Acer, r(p) = 0.987, Quercus, r(p) = 0.645, Betula, r(p) = 0.896, Pinus, r(p) = 0.732, Cupressaceae, r(p) = 0.695, Poaceae, r(p) = 0.950, Ambrosia, r(p) = 0.903, and Rumex, r(p) = 0.572, P <0.001). Daily Poaceae pollen levels were positively influenced by same-day high temperature (r(s) = 0.333 in Philadelphia and r(s) = 0.426 in Cherry Hill, P < 0.05). Daily Ambrosia pollen levels were inversely influenced by same-day total precipitation (r(s) = -0.174 in Philadelphia and r(s) = -0.257 in Cherry Hill, P < 0.05).
This is the first volumetric survey performed in either Philadelphia or Cherry Hill. Copious amounts of airborne pollen were seen from late April to early May and in early September. Pollen onset, duration, and year-to-year variability were similar at both sites. An awareness of local aeroallergen patterns is critical in the effective testing and treatment of atopic individuals.
空气过敏原采样可提供有关花粉季节的开始、持续时间和严重程度的信息,临床医生可利用这些信息指导皮肤试验和治疗的过敏原选择。
本大气调查报道:1)宾夕法尼亚州费城(1991年至1997年)和新泽西州郊区樱桃山(1995年至1997年)的空气传播花粉来源;2)花粉的开始、持续时间和峰值水平;3)空气传播花粉与选定气象变量之间的关系。
在相距11公里的两个地点,使用容积式旋转棒采样器(采样技术公司,明尼通卡,明尼苏达州)进行采样。
在费城和樱桃山,3年平均测量结果分别包括75.0%和74.2%的树木花粉、10.2%和8.3%的草花粉以及14.8%和17.5%的杂草花粉。主要的空气传播花粉类群有槭属、栎属、桦属、松属、柏科、禾本科、豚草属和酸模属。树木、草和杂草花粉季节分别从3月中旬持续到6月中旬、4月下旬持续到6月中旬以及8月中旬持续到9月下旬。禾本科花粉在9月出现第二个峰值。费城和樱桃山的每周平均花粉水平之间存在统计学显著相关性(槭属,r(p)=0.987;栎属,r(p)=0.645;桦属,r(p)=0.896;松属,r(p)=0.732;柏科,r(p)=0.695;禾本科,r(p)=0.950;豚草属,r(p)=0.903;酸模属,r(p)=0.572,P<0.001)。当日禾本科花粉水平受当日高温的正向影响(费城r(s)=0.333,樱桃山r(s)=0.426,P<0.05)。当日豚草花粉水平受当日总降水量的反向影响(费城r(s)=-0.174,樱桃山r(s)=-0.257,P<0.05)。
这是在费城或樱桃山进行的首次容积式调查。4月下旬至5月初以及9月初可见大量空气传播花粉。两个地点的花粉开始、持续时间和年际变化相似。了解当地空气过敏原模式对于特应性个体的有效检测和治疗至关重要。
