The purpose of this work was to integrate different methodologies to assess the potential ecological risk of estuarine sedimentary management areas, using the Sado Estuary in Portugal as case study. To evaluate the environmental risk of sediment contamination, an integrative and innovative approach was used involving assessment of sediment chemistry, sediment toxicity, benthic community structure, human driving forces and pressures and management areas organic load levels. The basis for decisionmaking for overall assessment was a statistical multivariate analysis appended into a score matrix tables, using a best expert judgment. The integrated approach allowed to identify from the 19 management areas analyzed, three with no risk but other three with high risk to cause adverse effects in the biota, related with the contaminants analyzed. The methodologies used showed to be effective as a support for decision making leading to future estuarine management recommendations.

“…Enrichment factors (EF) of the metals in the soils and plants were calculated for each metal relative to the background concentration obtained from a site (site A) free from traffic, industrial and solid waste pollution. The expression used for EF determination was that reported by Liu et al (2005) (Fang et al, 2006;Liu et al, 2005;Quevauviller et al, 1989;Reinmann et al, 2000;Schiff and Weisberg, 1999). For instance, Fe was used as the reference metal in this study because it was found most abundant in the soil and plant, implying that its occurrence within the experimental sites is natural.…”

ABSTRACT:The ability of Chromolaena odorata to accumulate and serve as biomarker to lead and cadmium metals pollution load had been revealed by this study. Samples of soils and Siam weed were collected to assess impacts of solid waste disposal and traffic density on the environment. Composite sample were collected from a solid waste dumpsite, three traffic polluted areas with varying traffic density and a background site distant from traffic. Concentration of eight elements: cadmium, cobalt, chromium, copper, iron, nickel, lead and zinc were determined in soil and plant samples and correlated together. Accumulative factors like pollution load index, transfer factor, contamination factor, enrichment factor were calculated for the metals in both plants and soils and used as basis for interpreting the state of the environment and ability of C. odorata to accumulate metals. The accumulative factors of plants were generally greater than that of soil samples indicating increased accumulative capacity of the plant. The accumulations of lead and cadmium in C. odorata were remarkable with contamination factor 10.51 and 23.50, respectively and mean enrichment factors 3.52 and 6.93, respectively. Other metals had lower accumulative factors. The distribution of metals and calculated factors placed solid waste disposal site as the most polluted site while the trend observed in areas with traffic pollution depicts the ability of C. odorata to clean up metal pollution by accumulating them. It can therefore be suggested that solid waste disposal negatively affects the environment more than traffic pollution subject to the volume of traffic.

“…There are many areas impacted by pyritic mine spreading all around Spain (Álvarez et al, 2003;Clemente et al, 2006;Rufo et al, 2007), which after becoming derelict sites now require environmental rectifications. In the pyrite deposits, natural weathering interaction may release elements such as As, Zn, Pb, Cu, Mn, Cd, Mo, Cr, and Ni which may contaminate water, soil and plant ecosystems at unacceptable levels (Quevauviller et al, 1989;Santos Oliveira et al, 2002). Releases may cause direct adverse effects on terrestrial and aquatic organisms.…”

El acceso a la versión del editor puede requerir la suscripción del recurso Access to the published version may require subscription This paper describes a new methodology for assessing site-specific environmental impact of contaminants. The proposed method integrates traditional risk assessment approaches with real and variable environmental characteristics at a local scale. Environmental impact on selected receptors was classified for each environmental compartment into 5 categories derived from the whole (chronic and acute) risk assessment using 8 risk levels. Risk levels were established according to three hazard quotients (HQs) which represented the ratio of exposure to acute and chronic toxicity values. This tool allowed integrating in only one impact category all the elements involved in the standard risk assessment. The methodology was applied to an abandoned metal mine in Spain, where high levels of As, Cd, Zn and Cu were detected. Risk affecting potential receptors such as aquatic and soil organisms and terrestrial vertebrates were assessed. Whole results showed that impact to the ecosystem is likely high and further investigation or remedial actions are necessary. Some proposals to refine the risk assessment for a more realistic diagnostic are included.Published by Elsevier B.V.
