“…The results of the 2000 sediment sampling (present study) are in good agreement with the sediment concentrations found by Chenhall et al (1992) and are higher or within the background sediment concentrations found by who analysed whole sediments, dried and ground to < 150 µm. The 1993 sediment metal concentrations (present study) are very much lower than the results of previous studies and are towards the lower end of concentrations found by .…”

Fish (dusky flathead-Platycephalalus fuscus and luderick-Girella tricuspidata) and shellfish (Anadara trapezia and Saccostrea commercialis) samples from Lake Illawarra in southeastern Australia were collected in 1993 and 2000 and analysed for a range of metals. Sediments with which the shellfish were in contact were also examined. The results were compared with shellfish data collected in 1976 and in an independent study in 1993. No reported data were available for comparison with the fish metal results. The results showed that trace metal concentrations in both fish and shellfish were generally low and represented minimal health risk. The dusky flathead, a predator species, had detectable concentrations of mercury, while the luderick, a herbivore, had values below detection limits. Metal concentrations in shellfish were in general agreement with those found in other studies, and showed that no apparent changes were occurring over time, except those that could be explained by changes in the age of the shellfish. Only copper in Lake Illawarra oysters showed greater concentrations than found in other southeastern Australian estuaries. It is recommended that future studies focus on organic and microbial contamination.

“…Here, sediments contain up to 20 0 times the concentrations of heavy metals found in rural areas, and the plants Sarcocornia quinqueflora, Suaeda australia and Triglochin striata all contain elevated levels (although not as high as those in the sediments) of Cu, Zn, Pb, Cd, Cr and Mn (Chenhall et al, 1992).

“…Other species of that genus, Sarcocornia, have been widely studied. For example, Sarcocornia perennis ( S. perennis ) has been exposed to different sea water concentrations to research its physiological responses [6]; Sarcocornia fructicosa ( S. fructicosa ) has been studied for its productivity and nutritional value [7]; Sarcocornia ambigua has been investigated for its process of germination [8]; and Sarcocornia quinqueflora has been included in an assessment of environmental pollution in coastal wetlands [9]. Lutts and Lefèvre (2015) [10] performed a literature review that demonstrated that S. fructicosa and S. perennis exhibit tolerance to high levels of heavy metals, which makes them promising candidates for phytoremediation of heavy metal pollution.…”

Being adapted to saline environments, halophytes are plant species that have received considerable attention due to their ability to cope with environmental stress factors, such as high concentrations of soluble salts and heavy metals. In this work, we focused on determining if the Sarcocornia neei (S. neei) plant can be considered as an indicator of heavy metal pollution in soil. This was done by analyzing the concentration of cadmium (Cd), lead (Pb), copper (Cu), and arsenic (As) in plants and soil sampled from two wetlands in the central zone of Chile: a wetland contaminated by industrial activities and a wetland protected by the Chilean government. In addition, 14 fertility parameters (pH, electrical conductivity, organic matter, nitrogen (N), phosphorus (P), potassium (K), sodium (Na), Pb, calcium (Ca), magnesium (Mg), Manganese (Mn), zinc (Zn), iron (Fe), and boron (B)) were analyzed for soil samples in both wetlands. This was done to differentiate between available elements and contamination by heavy metals. Plant and soil samples in the contaminated wetland exhibited significantly higher heavy metal concentrations in comparison to samples analyzed from the protected wetland. This indicates that the S. neei plant can be further researched as an indicator of heavy metal pollution in saline soils and possibly for phytoremediation purposes.
