Metals concentrations (As, Cd, Cu, Hg and Pb) in seawater, sediment and the seagrass (Enhalus acoroides) were analysed at Pulai River estuary, Johor Straits, Malaysia. In this research, Enhalus acoroides was used in order to find it's efficiency in up taking metals with a role in phytoremediation. Seawater, sediment and Enhalus acoroides samples were collected, and data of Pearson's correlation...

Polychlorinated biphenyls (PCBs) are persistent organic pollutants damaging to human health and the environment. Techniques to indicate PCB contamination in planta are of great interest to phytoremediation. Monitoring of dioxin-like PCBs in transgenic plants carrying the mammalian aryl hydrocarbon receptor (AHR) has been reported previously. Herein, we report the biomonitoring of non-dioxin-lik...

The health safety of Bt (Bacillus thuringiensis) corn (Zea mays L.) was studied using mouse testes as a sensitive biomonitor of potential toxic effects. Pregnant mice were fed a Bt corn or a nontransgenic (conventional) diet during gestation and lactation. After they were weaned, young male mice were maintained on the respective diets. At 8, 16, 26, 32, 63, and 87 days after birth, three male m...

The health safety of transgenic soybeans (glyphosate-tolerant or Roundup Ready) was studied using the mammalian testis (mouse model) as a sensitive biomonitor of potential toxic effects. Pregnant mice were fed a transgenic soybean or a non-transgenic (conventional) diet through gestation and lactation. After weaning, the young male mice were maintained on the respective diets. At 8, 16, 26, 32,...

The aim of this study was to test a possible use of Urtica dioica (common nettle) plant as a biomonitor of polonium (210)Po and lead (210)Pb contamination near phosphogypsum stacks by determining concentrations of these radionuclides in samples collected from the area of phosphogypsum stockpile in Wiślinka (northern Poland). The (210)Po and (210)Pb contents in roots depended on their concentrat...

The aim of this preliminary research was to establish if there are intersex occurrences in wild freshwater fish in Slovenian rivers and streams. In the first study we evaluated all fish species of both sexes obtained from the river Ljubljanica from its source to mouth. In the second study we focused on the rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta m. fario) males from 30...

The present study evaluated the potentials of phytoremediation and biomonitoring potentially toxic metals (PTMs) (Zn, Ni, Fe, Pb, Cu) in mangrove leaves Rhizophora apiculata from tropical ecosystem Sepang Besar River Lukut River, Peninsular Malaysia. Overall, studies concluded that (a) levels essential Cu, Zn lamina are significantly (p < 0.05) higher than MP, (b) Pb Ni MP lamina, (c) has be...

to examine metal content of dandelion plants in relation to environmental metal levels,concentrations of cd, hg and pb were analyzed in plant parts (leaves and roots) and soil samples from fivesites in the city of brno (czech republic), differentially impacted by pollution. soils and plants werecollected mid-april 2011. atomic absorption spectrometry was used to determine concentrations of thes...

oleander was tested as biomonitoring plant for surfactant polluted marine aerosol. potted plants in the greenhouse were sprayed once a week for 5 weeks with seawater containing sodium dioctyl sulfosuccinate (sds) at the following concentrations: 5, 10, 15, 30, 60, 120, 250, 500 mg/l. a significant correlation was found between sds concentration in the spray and surfactant deposit on the leaves ...
