“…High concentrations of APs were reported for other highly industrialized and urbanized areas, such as Hamilton Harbor of the Great Lakes (up to 72,000 ng/g dw of NP and 1800 ng/g dw of OP) [38], Virginia (USA) sediments adjacent to STPs and outfall (up to 14,100 ng/g dw) [23], and Jamaica Bay (NY, USA)(up to 13,700 ng/g dw of NP and 45 ng/g dw of OP) [25]. How- ever, the concentrations of NP and OP in surface sediments from the Pearl River estuary and nearby South China Sea ranged from 59 to 571 ng/g dw for NP and from 1 to 18 ng/g dw for OP [20], which were comparable to those found in Tokyo Bay (120-640 ng/g dw of NP and 6-10 ng/g dw of OP) [10]. The above result suggests that the Pearl River System has been significantly polluted by APs, and the contamination level in the PRD is one of the highest in the world.…”

“…4-Nonylphenol (NP) and 4-tert-octylphenol (OP) are more toxic and persistent than their ethoxylated precursors [7]. The concern over ubiquitous APs in the environment has been increasing due to their toxicity [8][9][10], estrogenic activity [11][12][13], and massive use. It was reported that the annual production of NP approximately reached 45,000 tons in the EU [14] and 16,000 tons in China [15].…”

“…Além disso, alguns valores de concentração indicam que o sedimento da bacia do Tarumã-Açu seja considerado poluído em alguns paises, principalmente nas proximidades do aterro sanitário (Tabela 5), representando um risco para a vida aquática, saúde humana (Ho et al, 2002).…”

RESUMOOs resíduos gerados em domicílios incluem diversos produtos, como pesticidas, produtos farmacêuticos, detergentes, óleos de cozinha, metais pesados contidos em baterias e outros utensílios. Esses resíduos são lançados continuamente em aterro sanitário ou lixões em cidades como Manaus. O chorume produzido nesses aterros, quando não tratados, contamina recursos hídricos superficiais e subterrâneos. Neste estudo foi feita uma avaliação das conseqüências da liberação do chorume no sistema hídrico da bacia do Tarumã-Açu. Amostras de água e sedimento foram coletadas nos igarapés Matrinxã, Acará, Bolívia, bacia do Tarumã-Açu e dentro do aterro sanitário (Manaus -Amazonas -Brasil) em março 2001. As amostras de água foram filtradas em filtro Milipore (0,45 mm de poro) e, em seguida, tratadas com HNO 3 concentrado. As amostras de sedimento foram peneiradas em malha de 0,053 mm e digeridas com HCl:HNO 3 (1:3) a 150 o C. As concentrações de alguns metais pesados (Co, Cu, Fe, Cr, Ni, Mn, Pb e Zn) foram determinadas nas amostras de água e sedimento por espectrometria de absorção atômica de chama. Os resultados revelaram que a concentração dos metais pesados é muito acima dos permitidos pela resolução 357/2005 do CONAMA em praticamente todos os locais amostrados, mostrando que o Aterro Sanitário é um dos principais responsáveis pelo impacto ambiental observado nos corpos hídricos estudados. As análises dos componentes principais (PCA) e hierárquica de cluster (HCA), revelam que os pontos de coleta localizados dentro do aterro sanitário apresentam características diferentes dos outros locais amostrados. Além disso, o HCA e PCA mostraram que existe uma similaridade entre os pontos de coleta localizados fora do aterro o que permite afirmar que o chorume do aterro se dissolve por todo corpo hídrico estudado.

“…4.2.4.4 Influence of ammonia toxicity in other porewater testing Ho et al (2002) reviewed the available published literature for porewater and wholesediment toxicity identification evaluation (TIE) testing to determine if one or more groups of contaminants (e.g., metals versus PAHs) were responsible for observed toxicity. Ammonia was identified as a contributory toxic agent in 69% of the porewater TIE studies (and was the sole toxic agent in 23% of the porewater TIE studies).…”

“…Although the number of studies included in the review was relatively small (i.e., n = 13 for porewater; n = 5 for whole-sediment), it does indicate the potential magnitude of the influence of ammonia in porewater testing. Ho et al (2002) suggested that the influence of ammonia may be an artifact of the test system (i.e., ammonia is water soluble, and therefore more likely to result in over-exposure in a porewater sample).…”

The magnitude and extent of contaminated marine sediment are frequently assessed using a Sediment Quality Triad framework involving multiple toxicity tests using a variety of species, toxicological endpoints and exposure systems. Data are integrated into an overall assessment of sediment quality using a weight of evidence approach. Guidance on the selection of appropriate toxicity tests recommends a wide range of organism type, life-cycle, exposure route, and feeding type be includedporewater bivalve larval development tests increases the number of exposure routes under consideration.Interpretation of porewater toxicity data are subject to limitations, in part, related to the extensive chemical manipulations associated with the extraction of in situ anoxic porewater and the subsequent aeration required for the laboratory-based toxicity test. The ability of the porewater-only test to represent ecologically relevant adverse effects in the field appears minimal. Results from concurrent porewater and elutriate toxicity testing using newly fertilized larvae of the bivalve, Mytilus galloprovincialis are provided to illustrate these problems. Porewater samples were consistently more toxic than the corresponding elutriate sample, and ammonia, a common confounding factor in sediment toxicology, was identified as the most likely toxic agent for the majority of samples.Porewater toxicity testing using M galloprovincialis is therefore not recommended as a routine element of the sediment quality triad unless additional chemistry (samples used for testing as well as in situ) are available to facilitate an appropriate interpretation of the resulting toxicity data. DEDICATIONFor all the support and understanding from my beloved wife, Elana.
