长期以来,当局已经证明了生物指标在监测环境污染状况方面的实用性。一些生物指标可以衡量环境污染物水平,许多树种已经过测试,用于监测目的。树木形态特征的差异表明了人类活动对不同材料的影响。确定了来自受污染地点的树皮和木材生物量的测量,并将其与来自清洁地点或具有不同污染源的区域的树皮和木材生物量进行了直接比较。然而,初步结果证明了该方法在实现疾病控制和促进健康战略以减少风险城市地区的环境和健康不平等方面的潜力。东方云杉和云杉。,尤其是它们的树皮,可以被认为是比松果更强大的铜(37.95毫克/千克)和锰(188.25毫克/千克)的存储,阿拉伯柏树,和Pseudotsugamenziesii,因此,它是铜和锰污染的更好的生物指示剂。考虑到研究的总浓度,污染被认为是由该地区的环境问题和交通造成的。铜的沉积,Mn,Ni,和锌元素被发现的孟子(60,443,58,和258毫克/千克)和东方白杨(76,1684,41,和378毫克/千克),似乎反映了大气与P.pinaster,C.Arizonica,还有C.Atlantica.自1983年以来,Ni和Zn的浓度已大大增加,而门氏疟原虫和东方疟原虫可能是强调污染田地的潜在有价值的生物指标。
Authorities have long proved the utility of bioindicators in monitoring the state of environmental pollution. Some biological indicators can measure environmental pollutant levels, and many tree species have been tested for suitability for monitoring purposes. The differences in morphological characteristics in the trees have demonstrated the effects of human activities on different materials. Measuring bark and wood biomass from contaminated sites was identified and directly compared with those from a clean site or areas characterized by distinct contamination sources. However, preliminary results demonstrate the approach\'s potential in the realization of strategies for disease control and promoting health to reduce environmental and health inequalities in at-risk urban areas.
Picea orientalis L. and Cedrus atlantica Endl., especially their bark, can be regarded as a more robust storage of Cu (37.95 mg/kg) and Mn (188.25 mg/kg) than Pinus pinaster, Cupressus arizonica, and Pseudotsuga menziesii, which and is therefore a better bioindicator for Cu and Mn pollution. Considering the total concentrations as a result of the study, the pollution is thought to be caused by environmental problems and traffic in the region. The deposition of Cu, Mn, Ni, and Zn elements was found P. menziesii (60, 443, 58, and 258 mg/kg) and P. orientalis (76, 1684, 41, and 378 mg/kg) and seems to reflect atmospheric quite clearly compared to P. pinaster, C. arizonica, and C. atlantica. Ni and Zn concentrations have significantly increased since 1983, and P. menziesii and P. orientalis can be potentially valuable bioindicators for emphasizing polluted fields.
