Resumo: | The mangrove acts as marine nursery, geochemical filter and source of income for the population, however, the degradation and pollution of mangroves may favor the release of toxic substances such as heavy metals. In this sense, this study aimed to analyze the levels of iron (Fe), copper (Cu), lead (Pb), mercury (Hg), nickel (Ni), cobalt (Co) and its relationships with the physical and chemical attributes, and to evaluate soil quality through national and international guidelines. They collected three profiles in each of the four areas studied (Bar Mamanguape- PB; estuary of the river Botafogo- B; Canal Santa Cruz-CSC, the Timbó- T River estuary). Samples were collected with samplers for flooded soils and the samples were subjected to hydrogen potential analysis (pH), redox potential (Eh), total organic carbon (TOC), carbonates (CO3-), grain size and by acid digestion method 3051A. The near neutral pH (6.5 to 8.5) and Eh levels in suboxic (Eh 100-350 mV) and anoxic (Eh <100 mV) discloses a geochemical reducing environment. The predominance of fine particles (silt and clay) and organic matter are present in soils around the estuary B and PB1 and PB2 profile, except in the soil CSC estuaries, T and PB3 profile where there was a predominance of sand fraction by situate near mouth. High positive correlations (r> 0.70) were found between fine particles, TOC and metals studied. Environmentally available mercury levels in the estuary B were higher than the ERM (Probable effects level), ERL (Effects range low) TEL (Threshold effect level), PEL (Probable effects level), VP (Value prevention) and the VRQ (quality reference value); Ni exceeded the TEL in some depth in the estuary B profiles, while the soils of other estuaries have levels above the VRQ. Thus, it is possible to identify contamination of Hg and Pb in the B and CSC estuary profiles; Cu B, CSC and PB; Ni B, and CSC PB; and Fe in the estuary B and PB; while for the Co there was no contamination in any of the studied estuaries. The FE (Factor enrichment) and Igeo (Geo-accumulation index) reveal that the B estuary had a severely serious enrichment (EF> 25) and is highly to extremely polluted (Igeo class 5) for Hg, respectively ; and low-enriched (EF <3) to the other metals. The Levels of Hg (Above PEL) and Ni (Above TEL) can be causing toxicity to benthic organisms. From the cluster analysis it was observed that distinctly from the others, Botafogo River estuary is impacted by metals due to strong pressure of human activities on the north coast of Pernambuco region. As a result, mangrove soil into the river Botafogo stands out as one of the marine ecosystem most impacted by Hg. |

Nesse sentido, o presente trabalho objetivou analisar os teores de ferro (Fe), cobre (Cu), chumbo (Pb), mercúrio (Hg), níquel (Ni), cobalto (Co) e suas relações com os atributos físico-químicos, além de avaliar a qualidade dos solos por meio de diretrizes nacionais e internacionais. Foram coletados 3 perfis em cada uma das 4 áreas estudadas (Barra de Mamanguape- PB; Estuário do rio Botafogo- B; Canal Santa Cruz- CSC; Estuário do rio Timbó- T). As coletas foram realizadas com amostradores para solos inundados e as amostras foram submetidas a análises de potencial de hidrogênio (pH), potencial de oxirredução (Eh), carbono orgânico total (COT), carbonatos (CO3-), granulometria e digestão ácida pelo método 3051A. O pH próximo da neutralidade (6,5 e 8,5) e o Eh em níveis subóxicos (Eh 100-350 mV) e anóxicos ( Eh <100 mV) revelam um ambiente geoquímico redutor. O predomínio de partículas finas (silte e argila) e matéria orgânica estão presentes nos solos em todo estuário B e no perfil PB1 e PB2, exceto nos solos dos estuários CSC, T e no perfil PB3 onde houve predominância da fração areia por situarem próximos à desembocadura. Altas correlações positivas (r > 0,70) foram encontradas entre partículas finas, COT e os metais estudados. Os teores de Hg ambientalmente disponíveis no estuário B foram superiores ao ERM (Probable effects level), ERL (Effects range low), TEL (Threshold effect level), PEL (Probable effects level), VP (Valor de prevenção) e o VRQ (Valor de referência de qualidade); o Ni superou o TEL em algumas profundidades nos perfis do estuário B, enquanto nos solos dos demais estuários apresentaram valores superiores ao VRQ. Desta forma, é possível identificar contaminação por Hg e Pb em perfis do estuário B e CSC; por Cu em B, CSC e PB; por Ni em B, CSC e PB; e por Fe no estuário B e PB; enquanto para o Co não houve contaminação em nenhum dos estuários estudados. O FE (Fator de Enriquecimento) e o Igeo (Índice de Geo-acumulação) revelam que o estuário B teve um enriquecimento severamente grave (FE > 25) e encontra-se altamente a extremamente poluído (Igeo classe 5) para o Hg, respectivamente; e baixo enriquecimento (FE < 3) para os demais metais. Os Teores de Hg (Acima do PEL) e Ni (Acima do TEL) podem está causando toxicidade a organismos bentônicos. A partir da análise de agrupamento observou que distintamente dos demais, o estuário do rio Botafogo encontra-se impactado por metais, devido a forte pressão das atividades antrópicas na região do litoral norte pernambucano. Em virtude disso, o solo do manguezal no rio Botafogo se destaca como um dos ecossistemas marinhos mais impactados por Hg.Submitted by Mario BC (mario@bc.ufrpe.br) on 2016-06-20T12:40:13Z No. of bitstreams: 1 Wildson de Morais Silva.pdf: 1890192 bytes, checksum: 7eeb21a8a05d68339c6b1b6af39b841d (MD5)Made available in DSpace on 2016-06-20T12:40:13Z (GMT).

description |
The mangrove acts as marine nursery, geochemical filter and source of income for the population, however, the degradation and pollution of mangroves may favor the release of toxic substances such as heavy metals. In this sense, this study aimed to analyze the levels of iron (Fe), copper (Cu), lead (Pb), mercury (Hg), nickel (Ni), cobalt (Co) and its relationships with the physical and chemical attributes, and to evaluate soil quality through national and international guidelines. They collected three profiles in each of the four areas studied (Bar Mamanguape- PB; estuary of the river Botafogo- B; Canal Santa Cruz-CSC, the Timbó- T River estuary). Samples were collected with samplers for flooded soils and the samples were subjected to hydrogen potential analysis (pH), redox potential (Eh), total organic carbon (TOC), carbonates (CO3-), grain size and by acid digestion method 3051A. The near neutral pH (6.5 to 8.5) and Eh levels in suboxic (Eh 100-350 mV) and anoxic (Eh <100 mV) discloses a geochemical reducing environment. The predominance of fine particles (silt and clay) and organic matter are present in soils around the estuary B and PB1 and PB2 profile, except in the soil CSC estuaries, T and PB3 profile where there was a predominance of sand fraction by situate near mouth. High positive correlations (r> 0.70) were found between fine particles, TOC and metals studied. Environmentally available mercury levels in the estuary B were higher than the ERM (Probable effects level), ERL (Effects range low) TEL (Threshold effect level), PEL (Probable effects level), VP (Value prevention) and the VRQ (quality reference value); Ni exceeded the TEL in some depth in the estuary B profiles, while the soils of other estuaries have levels above the VRQ. Thus, it is possible to identify contamination of Hg and Pb in the B and CSC estuary profiles; Cu B, CSC and PB; Ni B, and CSC PB; and Fe in the estuary B and PB; while for the Co there was no contamination in any of the studied estuaries. The FE (Factor enrichment) and Igeo (Geo-accumulation index) reveal that the B estuary had a severely serious enrichment (EF> 25) and is highly to extremely polluted (Igeo class 5) for Hg, respectively ; and low-enriched (EF <3) to the other metals. The Levels of Hg (Above PEL) and Ni (Above TEL) can be causing toxicity to benthic organisms. From the cluster analysis it was observed that distinctly from the others, Botafogo River estuary is impacted by metals due to strong pressure of human activities on the north coast of Pernambuco region. As a result, mangrove soil into the river Botafogo stands out as one of the marine ecosystem most impacted by Hg. |
