The aim of this study was to determine pollution by polycyclic aromatic hydrocarbons (PAH) and heavy metals in seawater and sediment in Kostrena coastal area, as well as their toxicity using bioluminescence based tests. Total PAH concentration in seawater ranged 1.7-155.3 ng/L. The share of carcinogenetic PAH was relatively high, ranging 22-48.3%. Nickel concentrations in seawater were beyond d...

In soil ecotoxicological studies, a toxic metal is usually added in the form of either an inorganic or organic salt with relatively high solubility. Nitrate, chloride, acetate, or sulfate are commonly considered as valid options for that aim. However, recent studies have shown that different salts of the same metal at the same cationic concentration may exhibit different toxicities to plants an...

Adverse effects of manufactured nickel oxide nanoparticles on the microalgae Chlorellavulgaris were determined by algal growth-inhibition test and morphological observation via transmission electron microscopy (TEM). Results showed that the NiO nanoparticles had severe impacts on the algae, with 72 h EC(50) values of 32.28 mg NiOL(-1). Under the stress of NiO nanoparticles, C. vulgaris cells sh...

OBJECTIVE While the potential toxicity of metals in humans is a well-established field of research, there are few studies that examine circulating concentrations of metals in large population-based samples. The aim of this study was to analyze levels of heavy metals and trace elements in both whole blood and serum in an elderly population, and to examine if gender, kidney function, haemoglobin ...

Water and sediment samples were collected from 20 location of the Buriganga river of Bangladesh during Summer and Winter 2009 to determine the spatial distribution, seasonal and temporal variation of different heavy metal contents. Sequential extraction procedure was employed in sediment samples for the geochemical partitioning of the metals. Total trace metal content in water and sediment samp...

The European Water Framework Directive prescribes that the environmental quality standards for nickel in surface waters should be based on bioavailable concentrations. Biotic ligand models (BLMs) are powerful tools to account for site-specific bioavailability within risk assessments. Several BLMs and simplified tools are available. For nickel, most of them are based on the same toxicity dataset...

Sanitary landfill leachate (SLL) is a mixture of highly toxic and recalcitrant pollutants that threatens the water quality Yucatán Peninsula karst aquifer, one most extensive aquifers on planet. To reduce adverse environmental impacts this wastewater, triple-stage Fenton process (FP) was applied in an old SLL. Removal efficiencies were evaluated terms physicochemical variables, metal(oid)s conc...

This study was carried out to determine the effects of different heavy metals and its doses on germination early seedling stage maize (Zea mays L.) at Akdeniz Univesity, Agricultural Faculty, Department Field Crops in 2017. Heavy such as lead (Pb), nickel (Ni), chromium (Cr), cadmium (Cd) mercury (Hg) 0 (control), 100, 200, 400 800 mg L-1 were used experimental factors. research laid factorial ...

Tanners, welders and workers in various industries are exposed to acute and chronic toxicity of these heavy metals world wide. The present work is undertaken to evaluate the genotoxic effects of Ni and Cr at two different exposure intervals with a single dose and the amelioration of this toxicity using curcumin. Ni in form of nickel chloride (4.216 X 10M) and Cr as potassium dichromate (1.36 X ...
