Abstract This paper analyzes the Australia – Anti-Dumping Measures on A4 Copy Paper panel report, the second recent WTO dispute to involve a challenge to Indonesia's paper industry. The Indonesian paper industry benefits from reduced-cost inputs because of the Indonesian government's influence and subsidies over the timber and pulp market. The report offers the first interpretation of ‘particular market situation’ under Article 2.2 of the WTO's Anti-Dumping Agreement. At the same time, it raises questions regarding the appropriateness of using anti-dumping measures to address what are fundamentally subsidy issues. While the panel ultimately found that Australia's measure was inconsistent with Article 2.2, the paper shows that the panel's interpretation of ‘particular market situation’ increases the relative attractiveness of using anti-dumping duties instead of countervailing measures. Two key points on the welfare implications of the decision can be made. The first relates to the motivations of the Australian paper industry and the imperfectly competitive market in which Australian Paper operates. The second is the importance of challenging subsidies rather than imposing anti-dumping duties where the subsidies in question have negative environmental effects.

Environmental Effects Monitoring

Abstract Sublethal toxicity tests successfully measured the improved quality of pulp mill effluents from the first cycle of environmental effects monitoring (1992–1996) to the second cycle (1997–2000). Test endpoints showed notable shifts to higher concentrations (less toxic). During the second cycle of monitoring, significantly more tests showed no effect in full-strength effluent. Five case studies were considered as part of this exercise. Most of the improvement came with installation of secondary treatment. Twelve Ontario mills with secondary treatment showed reduced toxicity, compared to results with primary treatment. All 29 sets of sublethal data showed higher IC25s during the second cycle, and 23 of these differences were statistically significant. Any other changes between the two cycles of study caused only marginal overall improvement in toxicity, judging by 12 freshwater mills in British Columbia which had secondary treatment during both cycles. Sublethal tests successfully predicted the zone of potential effect in receiving water, agreeing with effects observed in biological surveys. Overlapping zones from multiple discharges could also be demonstrated. In a situation near Niagara Falls, sublethal tests estimated the proportions of toxic loading that four mills contributed to one water body. The prediction was realistic; the actual toxicity found for a mixed effluent was 57% of that predicted from separate toxicities. The conservative prediction agrees with the usual less-than-additive sublethal action of combined toxicants.

Special Circumstances

Clemmer and Beebe have pointed out that surface structures on graphite substrates can be misinterpreted as biopolymer images in STM experiments. We have been using electrochemical methods to react DNA fragments onto gold electrodes for STM and AFM imaging. The adsorbates produced in this way are only homogeneous in special circumstances. Searching an inhomogeneous substrate for ‘desired’ images limits the value of the data. Here, we report on a reversible method for imaging adsorbates. The molecules can be lifted onto and off the substrate during imaging. This leaves no doubt about the validity or statistical significance of the images. Furthermore, environmental effects (such as changes in electrolyte or surface charge) can be investigated easily.
