[The labor process and work-related accidents among garbage collectors in Rio de Janeiro, Brazil]

This study describes the work performed by garbage collectors in the Rio de Janeiro City Street Cleaning Company (COMLURB) (Rio Comprido division) and its consequences for their health. Data were collected through interviews and on-site video documentation. A detailed description of the work process was performed. In addition, we analyzed the workers' reports of their lifetime experience with job-related risks and accidents.

An assessment of the risk of foreign animal disease introduction into the United States of America through garbage from Alaskan cruise ships.

The United States Department of Agriculture, Animal and Plant Health Inspection Service (USDA-APHIS) has been exploring methods of quantitative risk assessment to support decision-making, provide risk management options and identify research needs. With current changes in world trade, regulatory decisions must have a scientific basis which is transparent, consistent, documentable and defensible. These quantitative risk assessment methods are described in an accompanying paper in this issue. In the present article, the authors provide an illustration by presenting an application of these methods. Prior to proposing changes in regulations, USDA officials requested an assessment of the risk of introduction of foreign animal disease to the United States of America through garbage from Alaskan cruise ships. The risk assessment team used a combination of quantitative and qualitative methods to evaluate this question. Quantitative risk assessment methods were used to estimate the amount of materials of foreign origin being sent to Alaskan landfills. This application of quantitative risk assessment illustrates the flexibility of the methods in addressing specific questions. By applying these methods, specific areas were identified where more scientific information and research were needed. Even with limited information, the risk assessment provided APHIS management with a scientific basis for a regulatory decision.

Acute and sublethal toxicity of seepage waters from garbage dumps to permanent cell lines and primary cultures of hepatocytes from rainbow trout (Oncorhynchus mykiss): a novel approach to environmental risk assessment for chemicals and chemical mixtures.

In order to evaluate the suitability of cytopathological criteria in isolated fish hepatocytes as endpoints in (eco)toxicological research, liver cells isolated from rainbow trout (Oncorhynchus mykiss) by collagenase perfusion were exposed in vitro for up to 5 days to sublethal dilutions of two seepage water samples collected from garbage dumps. Hepatocytes were analysed with respect to acute (lactate dehydrogenase leakage) and sublethal toxicity (electron microscopy, stereology). In addition, acute toxicity (24 h) was tested in the piscine fibrocytic cell line R1 by means of crystal violet staining and neutral red retention. Acute toxicity in R1 cells and isolated hepatocytes could only be documented for sample I at dilutions of 1:2 and 1:4. This difference in toxicity could be corroborated by cytological alterations in isolated hepatocytes, which could be documented for dilutions of 1:100 and 1:8 in samples I and II, respectively. Ultrastructural changes were time- and dose-dependent and included reduction of hepatocellular volume, disturbance of intracellular compartmentation, modified heterochromatin distribution, transformation of rough endoplasmic reticulum into concentric membrane whorls, proliferation of lysosomes and cytoplasmic vacuoles, as well as reduction of hepatocellular glycogen. Although several hepatocellular reactions were found after exposure to either sample, the syndrome of ultrastructural alterations allowed clear differentiation between the two samples. Results illustrate that cytological effects far below macroscopically detectable damage can be discovered not only in intact fish, but also in fish cell culture systems. On the basis of the data presented, a multi-tiered test procedure for aquatic toxicity assessment exclusively based on tests with fish cell culture systems is proposed: (1) rapid screening for acute toxicity with permanent cell lines; (2) short-term tests with more complex, yet more sensitive systems such as primary hepatocytes with straightforward biochemical endpoints; (3) prolonged exposure of isolated hepatocytes in combination with ultrastructural and biochemical investigations as a sensitive tool to detect adverse effects at environmentally relevant toxicant concentrations.

[Rainer Werner Fassbinder's "Garbage, the city and death"-- a German landscape of the soul].

No other recent "art event" has aroused so much public debate in Germany as Fassbinder's play "Garbage, City, Death" (1976). The controversy it sparked on its appearance has still not entirely died down. In a painstaking psychoanalytic interpretation Vogt first shows that the play achieves an artistic representation of the unconscious dilemma besetting the second generation of non-Jewish Germans in their relationship to National Socialism. In Fassbinder's play this dilemma, which is bound up with vicarious guilt feelings, is however only presented and not in any way worked out. The upshot is that all those forms of identification with German traditions that have been repudiated on a conscious level re-enter, as it were by the back door, and attain a new virulence. The author demonstrates that at the heart of the play a mechanism of guilt-refusal is operative that inverts the historical culprit-victim relation and makes the Germans themselves into the real victims. In the second part of his article Vogt is concerned to situate the play and the controversy surrounding it in a broader political context--Bitburg (1985), the "historians' conflict" (1986), Jenninger's speech (1988)--revealing a specific collective psychological inscape in present-day Germany for which, in its profounder well-springs, Fassbinder's play may be legitimately regarded as symptomatic. Fassbinder (born 1945) articulates for his generation aspects of an "ethnic disturbance" (George Devereux) which continues to persist precisely because there is a German past "that refuses to go away" (Ernst Nolte).
