本研究是为了确证小动物各种组织中的铅蓄积与交通密度、距公路的距离的关系。在美国科罗拉多州北部中心,丹佛城与怀俄明州边境之间,沿着25号州间公路,从以下4个具有不同交通量的地方捕获白足小鼠,用以确定交通量对各种组织中铅蓄积的影响。每天通过车辆数第1点为4,200辆;第2点为9,500辆;第3点为18,500辆;第4点为38,000辆。第4点还具有4%的向上坡度。为了确定不同组织中铅蓄积与靠近公路之间的关系,在一个多草地区,沿着91米长、183米宽范围内捕获小鼠,该地交通量为18,500辆/天(第5点)。此外,在每点沿公路垂直面的
The purpose of this study was to confirm the relationship between lead accumulation and traffic density in various tissues of small animals and their distance from the road. In the northern center of Colorado, between the Denver and Wyoming borders, along Interstate 25, white-footed mice are captured from four different volumes of traffic to determine the amount of traffic that can be found in various tissues Impact of lead accumulation. The number of vehicles passing by day was 4,200; the second was 9,500; the third was 18,500; the fourth was 38,000. Point 4 also has a 4% uphill slope. To determine the relationship between lead accumulation in different organizations and the proximity of roads, mice were captured along a 91-meter long, 183-meter wide area in a grassy area with 18,500 vehicles / day (point 5) . In addition, each point along the vertical road surface
