“…4h). These sites represent anoxic conditions, allowing trace elements to be captured by the minerals and organic matter (Zhao et al, 2014). According to previous studies (Sansalone and Kim, 2008;Zhao et al, 2014), organic matter has an affect on chemical speciation transformation and the absorption of trace elements in sediments and can affect the toxicity and bioavailability of trace elements.…”

Measurement of elevated trace elements is an important component of environmental assessment and management of estuarine marine sediments in systems adjacent to concentrated human activity. The present study surveys the estuarine sediments in selected tributary bays, creeks, and the upper segments of the Georges River system, NSW, Australia, which flows into the Tasman Sea through Botany Bay. A total of 146 surface sediment samples were analysed by X-ray fluorescence. Potential pollution of sediments was evaluated using potential load index, modified degree of contamination, and potential ecological risk index. The spatial distribution of trace elements varies between sites. Variable sources of contamination, including runoff from catchment areas, and emissions from watercraft and boatyards are contributing sources. Bay morphologies and their interactions with catchment and tidal flows play significant roles in the distribution of trace elements. The greatest concentration of trace elements occurs around discharge points and in the inner parts of bays that have high percentages of mud particles and organic matter. The lowest contamination by trace elements was found in sandy sediments along the shoreline and edges of the bays. Trace element distributions decline in concentration in residential-free areas and reach background levels in deeper sediment cores. The concentrations of trace elements were controlled by discharge points from the catchment area, marine boat activities, bay morphology, and sediment types (sand, silt, and clay). The highest pollutant concentrations are the result of past legal, but uncontrolled, discharge of waste from manufacturing into Salt Pan Creek. Creek.

“…These trace metals can have deleterious effects on fauna, flora and aqua microorganisms. Trace metals can enter into human bodies via the food chain, inhalation or dermal absorption, and may lead to critical health disorders that affect the nervous system, endocrine system and/or the immune system (Romero et al 2013;Zhao et al 2014). The trace metal concentrations that were measured in Kogarah Bay were compared with the concentrations of trace metals from marine sediments (Table 4) in previous Australian studies (Birch and Taylor 1999;Jones et al 2003) and around the world (Hamer and Karius 2002;Pekey 2006).…”

“…Trace metals tend to be adsorbed, absorbed and accumulated in the fine to very fine sediment particle fraction, which eventually transfers to depositional areas (Mendiguchía et al 2006). Moreover, the discharge of untreated urban wastewater can lead to the accretion of organic matter that may contain high levels of total phosphorus, nitrogen and carbon in the sediments, resulting in the reduction of dissolved oxygen in water (Ruiz et al 2006;Zhao et al 2014). The main purpose of this paper is to provide a better understanding of the geochemical status, toxicological spatial and temporal distribution of trace metals in Kogarah Bay, as well as to determine the relationship between the spatial pattern of trace metals and distribution of sedimentary fractions.…”

The distribution of trace metals (spatial and temporal) and sedimentary fractions were investigated to identify the concentrations and sources of trace metals within Kogarah Bay, NSW, Australia. A total of 59 surface sediments and six subsurface samples from core of the sediment were collected. The contamination factor and pollution load index indices used to evaluate environmental effects of trace metals. The study area was found to be uncontaminated with Cr and Ni, moderately contaminated with As and considerably contaminated with Cu, Zn and Pb. The concentrations of Cr and Ni were below both effect range low and effect range median, while As, Cu, Zn and Pb were slightly above effect range low. The highest concentrations of these trace metals such as Cu, Zn and Pb were found in the north, northwest and southeast of the bay, close to discharge points, stormwater outlets and around boatyards and watercrafts. The spatial distributions of metals were strongly related to muddy particles and organic matter. The temporal sediments of metals declined with increased sediment depth, which reflects accumulation of trace metals since European settlement in this area. Furthermore, the source of the trace metals was found to be stormwater outlets, gasoline fumes, boatyards and other human activities.

“…The rapid industrialization of society leads to the release significant amounts of pollutants, particularly metals, to land. The exhaust gases of vehicles, mining and smelting, precipitation are considered to be sources of pollution (Chabukdhara and Nema, 2013;Christoforidis and Stamatis, 2009;Kelepertzis, 2014;Wei and Yang, 2010;Zhao et al, 2014). Recently, soil contamination with metals is increased through the application of organic fertilizers, the placement of wastes on the land (Tejada et al, 2011;Vig et al, 2003).…”

A laboratory-based simulation of exposure of the soil community in a gray forest soil to cadmium and glucose has been conducted. It was established that while growing in a fertile medium microbial communities isolated from a soil sample contaminated with cadmium have a substantially increased phase of growth delay and there is a reduction in total growth. While analyzing communities by Biolog Ecoplate method, it was found that, as compared to the community isolated from a soil rich in glucose, the community in a soil with cadmium is characterized by significantly lower AWCD, R and H indices, in which the differences increase with time of incubation. Also differences in the pattern and rate of recyclable substrates have been revealed. The resulting data suggest changes in the functional activity of the microbial community in the soil under the influence of cadmium.
