“…Calcium has been widely used in many industries such as food industry and construction industry. Small fish bone is an important source of calcium and it can increase calcium bioavailability (Larsen et al, 2001), and thus calcium as an alkali will be used to neutralize the acid mine drainage and remove the dissolved heavy metals as well. Bone meal which will consist of chicken bones and fish bone are selected because they are potential source to obtain calcium.…”

The typical methods of treatment for acidic and metal contaminated water effluent such as the Acid Mine Drainage (AMD) will always focus on either civil engineering methods, such as disposal, excavation, drainage and encapsulation or process based technologies such as effluent washing and treatment. These techniques are not environmental friendly, costly and unsustainable, thus environmental damaging. Nowadays, there is a growing need for an alternative remediation treatment that is innovative and more natural in order to prevent pollution in the environment. Therefore, in this study, a new alternative treatment, that is more organic, biodegradable and cost effective, using bone meal was presented. In this research, bone meal comprising of chicken bones were used as an alternative passive treatment to determine its potential in neutralizing and removing heavy metals from the abandoned cooper mine, Mamut Acid Mine Drainage (AMD) waste water effluent. A pretreatment process for bone meal was performed by incineration process where it was heated up in the furnace at 500°C for 24 h after it was cleaned, crushed, boiled and dried. Batch experiment test has been carried out to test whether the selected bone meal sizes 45, 75 and 150 µm was able to neutralize the AMD Mamut water samples. Inductive Plasma Couple-Atomic Emission Spectrometry (ICP-AES) test was carried out to test the concentration of the heavy metals before and after the treatment. The surface morphology of bone meal was examined by Scanning Electron Microscopy (SEM). Enlargement of pores after the neutralization treatment was seen on the surface morphology of the bone meal by SEM analyses. A significant rising of pH from 2.98 to 5.69 within 6 h 30 min was observed during neutralization process and 99% removal of Fe, Zn, Al, Cu and 36% removal of Mg concentration was achieved after the treatment through the neutralization treatment of the AMD waste water effluent. The results from this study conclude that bone meal has the potential to neutralize and remove heavy metals from acidic and metal contaminated AMD waste water effluent.

“…This corresponds to 2,530 µg Pb and 970 µg Zn in a blue mussel with a shell length of 6 cm. According to previous studies, suspension feeders such as blue mussels take up metals bound to particulate matter and food particles as well as metals in dissolved form within the seawater (Rainbow, 1995;Larsen et al, 2001). Consequently, the high Pb and Zn concentrations in 1989 and 1990 are considered the result of both a higher dispersion of dissolved and particle-bound Pb and Zn at that time as a consequence of removal and subsequently disposal of M A N U S C R I P T…”

“…The Black Angel Lead-Zinc Mine in Maarmorilik in West Greenland (Figure 1) is an important example in mining history where discharge of waste materials into the sea caused a significant release and dispersion of metals within a larger fiord system (Asmund, 1992a;Larsen et al, 2001;Elberling et al, 2002). The Black Angel Mine was operated between 1973 and 1990 and during this period, so-called mine tailings from ore treatment were discharged into a small partly-enclosed fiord Affarlikassaa (named the A-fiord).…”

“…Embora não haja mais a exploração do chumbo, os efeitos ambientais dessa atividade continuam presentes, via descarga dos efluentes e rochas com alto conteúdo de metais pesados 26 . Alguns estudos têm reportado o impacto ambiental por metais provenientes de atividades de mineração [27][28][29][30] . Neste trabalho, os metais avaliados foram Pb, devido aos problemas com a mineração, Cd, Cu e Zn pois, segundo a CETESB, esses metais têm sido encontrados no PETAR…”

Recebido em 14/10/04; aceito em 4/5/05; publicado na web em 10/8/05 EVALUATION OF METAL CONTENT IN SEDIMENTS OF THE BETARI RIVER IN THE PARQUE ESTADUAL TURÍSTICO DO ALTO RIBEIRA -PETAR-, SÃO PAULO, BRAZIL. The subsoil of the Vale do Ribeira was the focus of mining industries for the exploration of lead, mainly inside the park -PETAR. Despite the fact that the exploration has ended, the environmental effects of those activities are still present, due to great amounts of heavy metals that are leached. Concentrations of pseudo-total and bioavailable metals were determined in sediment samples of the Betari River, using atomic absorption spectrometry. The results demonstrated that the sediments are contaminated by Pb, Zn and Cu. The findings can contribute to an efficient and environmentally and economically adequate management of the park, for the conservation and the protection of the area.Keywords: river sediment; trace metals; sustainable development. INTRODUÇÃOO crescimento industrial desordenado gera como conseqüên-cia uma grande liberação de compostos indesejáveis ao meio ambiente, causando danos à vida animal e vegetal. Desta forma, apesar dos bens minerais contribuírem para o desenvolvimento industrial, são, também, fontes poluidoras quando lançados em grande quantidade ao meio ambiente 1 . O lançamento dos efluentes industriais e domésticos, o intemperismo e outros processos pedogênicos que sobre a rocha matriz geram os elementos-traço podem propiciar um perfil completamente diferente ao da dinâmica de sedimentação encontrada nos ambientes naturais não perturbados 2 . Mas essas não são as úni-cas fontes que geram esse tipo de elementos os quais podem, ainda, ser incorporados aos ambientes naturais por microrganismos, decomposição de restos de animais e fontes antropogênicas 3 . Os sedimentos desempenham um papel importante no tocante ao destino de xenobióticos em ambientes aquáticos, pois refletem a quantidade corrente do sistema aquático e podem ser usados para detectar a presença de contaminantes que não permanecem solúveis após seu lançamento em águas superficiais 4 . Os sedimentos são considerados de grande importância na avaliação do nível de contaminação dos ecossistemas aquáticos, devido não só a sua capacidade em acumular elementos-traço mas, também, por serem reconhecidos como transportadores e possíveis fontes de contaminação, já que tal compartimento ambiental pode liberar espécies contaminantes 5,6 . Tais espécies são geralmente liberadas do leito do sedimento devido a alterações nas condições ambientais e físico-químicas (pH, potencial redox e ação microbiana, entre outras), podendo contaminar a água e outros sistemas ambientais, afetando a qualidade da água, levando à bioacumulação e transferência na cadeia trófica 5,7 . Os metais, principalmente os metais pesados, em grande concentração, merecem maior preocupação, principalmente por serem não degradáveis, permanecendo por longos períodos no ambiente, principalmente nos sedimentos. Nos últimos anos, tem aumentado a investigação sobre metais pr...
