“…Low residues were detected in the emergent flies. Larvae of midge species are perceived to be relatively insensitive organisms in toxicity assessments (Ingersoll, 1993). This conclusion is in part based on the practice of conducting shortterm tests with relatively robust forth instar larvae.…”

The current draft EC regulatory guidance document for the authorisation of plant protection products, directive EEC 91/414, contains provision for testing the potential toxicity of pesticides to sediment dwelling organisms. Development of an appropriate method is currently in progress, by a German regulatory and industry working group. The compounds which are expected to trigger sediment toxicity data are likely to be those which are relatively persistent, with a high Kow, with the potential for significant adsorption to sediments, and may have previously demonstrated toxicity to aquatic organisms. The current proposal from this working group involves an artificial sediment, prepared in accordance with OECD guideline 207, as used for earthworm toxicity tests. The implications of using this sediment on the distribution, fate and availability of the compound under test are considered. This paper presents toxicity data for Chironomus riparius generated using radiolabelled Prochloraz® in systems using this artificial sediment and two natural sediments. The fate of prochloraz was also investigated in the same systems and compared with data generated from sediment/water studies carried out in accordance with regulatory guidelines. At the maximum Predicted Environmental Concentration (PEC) of 195/~g-l nominal, prochloraz had no effects on the survival and development of Chironomus riparius. The fate of the compound in the systems used was enhanced possibly as a result of photodegradation.

BACKGROUNDAberdeen Proving Grounds (APG) is approximately 50 km northeast of Baltimore, Maryland and is a designated Major Range Test Facility operated by the U.S. Department of Defense. APG is located on approximately 7,000 ha of coastal plain bordering the upper Chesapeake Bay. Since development and testing of weapons and weapon systems is a primary function of APG, about 80 to 85% of the land at APG is dedicated to ballistic test ranges, impact areas, vehicle test tracks, and other test facilities. Armor-piercing penetrators composed of a DU alloy (99.25% DU and 0.75% titanium) have been field-tested at APG for in-flight accuracy since the 1950s. DU has been used in armor-piercing penetrators because of its high density, good mechanical properties, pyrophoric qualities, and relatively low cost.

Amphipod Sediment Toxicity Tests

et al. 2004

The purpose of the amphipod solid‐phase toxicity test is to determine if test sediment samples reduce survival (growth, reproduction, etc.) of exposed organisms relative to that of organisms exposed to control and reference sediment. Test results are reported as treatment (station) or combination of treatments (sites or chemicals) that produce statistically significant reduced survival (growth, reproduction, etc.) from control or reference sediments. Sediment amphipod tests (3) can be used to (1) determine the relationship between toxic effects and bioavailability, (2) investigate interactions among contaminants, (3) compare the sensitivities of different organisms, (4) determine spatial and temporal distribution of contamination, (5) evaluate hazards of dredged material, (6) measure toxicity as part of product licensing or safety testing or chemical approval, (7) rank areas for clean up, and (8) set cleanup goals and estimate the effectiveness of remediation or management practices.
