11. Lindane meets several internationally accepted criteria for persistence, bioaccumulation and toxicity.

12. Students read about bioaccumulation and Biomagnification, then position themselves as part of the ocean food web

13. A wide range of bioaccumulation factors (BAF) for alpha-HCH has been reported in several studies.

14. A diet-weighted bioaccumulation factor of approximately 3 was determined for the trout (Martin et al., (2004b).

15. Definition of bioaccumulation : the accumulation over time of a substance and especially a contaminant (such as a pesticide or heavy metal) in a living organism Other Words from bioaccumulation Bioaccumulate \ ˌbī-​ (ˌ)ō-​ə-​ˈkyü-​m (y)ə-​ˌlāt

16. Furthermore, erosion and enhanced hydrodynamic forces counteract bioaccumulation in this lagoon cramped by dikes and causeways.

17. Consequently, bioaccumulation, and in particular Biomagnification of MPs and associated chemical additives, are often inferred to occur in marine food webs

18. Effect of dissolved organic matter of various origins and Biodegradabilities on the bioaccumulation of polycyclic aromatic hydrocarbons in Daphnia magna

19. Unexpected Biomagnifications and bioaccumulation of heavy metals (HMs) in the surrounding environment has become a predicament for all living organisms together with plants

20. Bioaccumulation of substances within aquatic organisms can give rise to toxic effects over longer time scales even when actual water concentrations are low.

21. To Bioaccumulate is to undergo bioaccumulation (or biological accumulation)—the process by which foreign substances, such as pesticides or toxic chemicals, build up within an organism

22. While Biomagnification refers to increasing concentration of substances with each successive link in the food chain, bioaccumulation is the increase in the concentration of a particular substance within an organism.

23. Biomagnification results from the process of bioaccumulation and biotransfer in which the tissue concentration increases in organisms higher up the food chain as a result of predation (see Figure 5)

24. This activity will demonstrate the concepts of bioaccumulation and Biomagnifications using the classic example of DDT (dichloro-diphenyl-trichloroethane), as well as review how energy is transferred through a food chain.

25. Cerium(III) nitrate hexahydrate Revision Date 19-Jan-2018 LC50: = 0.3 mg/L, 96h semi-static (Oncorhynchus mykiss) Persistence and Degradabilitybased on information available.May persist Bioaccumulation/ AccumulationNo information available

26. mortality of the control worms and the worms in each test vessel and any observed abnormal behaviour (e.g. soil avoidance, lack of reproduction in a bioaccumulation test with enchytraeids);

27. The octanol-water partition coefficient (log Kow # ) for alpha-HCH indicates a potential for bioaccumulation ( # ), though it is below the value of # stated in Annex D paragraph # (c)(i) of the Stockholm Convention

28. Biomagnification The result of bioaccumulation and biotransfer by which tissue concentrations of chemicals in organisms at one trophic level exceed tissue concentrations in organisms at the next lower trophic level in a food chain.

29. Aquacultural tilapia (Oreochromis mossambicus L.) and shrimp (Penaeus monodon L.) from groundwater-cultured ponds in southwestern Taiwan were analyzed to estimate arsenic (As) bioaccumulation and the potential health risk to human intake

30. Anilin Not listed Oncorhynchus mykiss: LC50 = 10.96 mg/L 96h EC50 = 425 mg/L 5 min EC50 = 488 mg/L 15 min EC50 = 0.16 mg/L 48h Persistence and DegradabilityPersistence is unlikely Bioaccumulation/ AccumulationNo information available

31. Effect of dissolved organic matter of various origins and Biodegradabilities on the bioaccumulation of polycyclic aromatic hydrocarbons in daphnia magna Jean-Marie Mouchel INTRODUCTIONPolycyclic aromatic hydrocarbons (PAHs) are carcinogenic and mutagenic organic contaminants, usually by-products of industrial and urban activities as fuel

32. - include chronic toxicity testing on the most sensitive aquatic organisms identified in the Phase IIA assessment, e.g.: the fish early life stage test, the Daphnia reproduction test, 72-hour algae tests and a bioaccumulation study,

33. “ Biomagnification (or bioaccumulation) refers to the ability of living organisms to accumulate certain chemicals to a concentration larger than that occurring in their inorganic, non-living environment, or in the case of animals, in the food that they eat.

34. Biomagnification (or bioaccumulation) refers to the ability of living organisms to accumulate certain chemicals to a concentration larger than that occurring in their inorganic, non-living environment, or in the case of animals, in the food that they eat

35. Bioaccumulation and Biomagnification are two concepts intimately tied to human health and difficult ones to comprehend. There are many chemicals and toxins that can bioaccumulate in organisms and biomagnify through the food web, including DDT, PCBs, mercury, and algal biotoxins.

36. The poisons Bioaccumulate in the wildlife that prey on rodents, and they, too, become sickened or die from "rodenticide intoxication." Although second generation anticoagulants are designed to kill in one feeding, both first and second-generation anticoagulants cause bioaccumulation and …

37. Bioaccumulation and Biomagnification are two different processes that often occur in tandem with one another.Bioaccumulation is the process by which toxins enter the food web by building up in individual organisms, while Biomagnification is the process by which toxins are passed from one trophic level to the next (and thereby increase in concentration) within a food web.
