摘要

Method of detecting chronic exposure of an organism to a pollutant, and for evaluating biological damage due to chronic exposure to sublethal levels of pollutants and kits for carrying out the method are disclosed. The methods comprise:PP(a) sampling at least one organism in order to determine whether it has been chronically exposed to a sublethal concentration of one or more pollutants in its environment, under sampling conditions that do not induce any additional heat shock protein (hsp) response in the organism;PP(b) obtaining a sample of cells or secretions of said organism, suspected of having elevated levels of heat shock proteins and solubilizing the heat shock proteins in the sample; andPP(c) measuring the concentration of a heat shock protein in said sample.PP The invention also provides methods for evaluating biological damage due to chronic exposure to a sublethal concentration of one or more pollutants comprising detecting chronic exposure of the organism by the above method and then comparing the measured concentration of hsp to a predetermined standard calibration curve which correlates hsp concentration with physiological impairment of growth or reproductive processes, and kits for carrying out the methods.

本发明还提供了评估由于长期暴露于一种或多种亚致死浓度的污染物而引起的生物损伤的方法。包括通过上述方法检测生物体的慢性暴露,然后将测得的hsp浓度与预定的标准校准曲线进行比较,该标准的标准曲线将hsp浓度与生长或生殖过程的生理损害相关联,以及用于实施该方法的试剂盒。
