“…We examined tadpole livers for evidence of histopathology such as necrosis, lesions, hepatocyte degeneration and vacuolation. PAHs can also 2 3 2 interfere with the heme biosynthetic pathway and lead to hepatic porphyria in which the liver accumulates excess uroporphyrin (Peakall 1992). Because uroporphyrin is the porphyrin most affected by PCBs and other PAHs, we measured uroporphyrin levels in tadpole livers.…”

“…Because uroporphyrin is the porphyrin most affected by PCBs and other PAHs, we measured uroporphyrin levels in tadpole livers. Additionally, induction of cytochrome P450 (cyp P450) enzymes, a large family of metabolizing and detoxifying liver enzymes, has been used as a sensitive biomarker for organic pollutant exposure (Peakall 1992). …”

“…Assessment of the effects of hazardous chemicals on human health has concentrated on the individual, and on organ, cellular, and subcellular causes of ill health (5,8). This has led to investigations aimed at identifying the mechanisms of action of the causative agents.…”

“…At every level of ecological organization, from the individual to ecosystems, there are indicators or measures (biomarkers or bioindicators) of well-being (5,6). At the population level, population stability is the end point of concern (21).…”

“…Recently, the importance of landscape scale considerations has moved to the fore, as we realize that ecological processes cannot always be easily compartmentalized (1)(2)(3)(4). Understanding the effects of chemicals and measuring or assessing the effects of chemicals at the different levels of organization in ecological systems requires understanding the factors that affect exposure and response (5,6). Differences in individual physiology, behavior, and ecology influence the extent to which individuals and populations are exposed to hazards, as well as how they respond (7).…”

Differences in genetic susceptibility to hazardous chemicals affect individuals of both human and nonhuman populations. In both cases, differences in response to chemicals or general ill health result as a function of these differences in genetic susceptibility. However, ecological systems are a compilation of hundreds or even thousands of different species, resulting in structural and functional characteristics that are themselves affected by differences in susceptibility. Although individual and population differences in susceptibility to hazardous chemicals underlie effects at the community and the ecosystem level, they do not account for all differences. propose a twotiered approach to evaluating susceptibility to ecological systems: a general susceptibility as a function of ecosystem type (based on structure and function of that system) and a differential in susceptibility within broad ecosystem types as a function of biotic and abiotic factors. In terrestrial ecosystems, the two factors that most affect overall susceptibility are species diversity and hydrology; evaluation of the effects of hazardous chemicals involves measuring species diversity and water movement. This same methodological approach can be applied to aquatic ecosystems and to highly altered ecosystems such as agriculture, forestry, fisheries, and urbanization.Environ Health Perspect 1 05(Suppl 4): 843-48 (1997)

The use of persistent organochlorine insecticides has had serious consequences on populations of birds of prey and fish‐eating bird species. The question now is whether current pesticides have the same potential to reduce bird populations. In order to answer this, however, the question must be defined carefully, which is one of the most difficult tasks facing any attempt to measure the impact of pesticides on birds because so many variables are involved. Overall, however, this article argues that in cases of acute poisonings in birds of prey, a few pesticides are responsible for most of the problems.
