ZINC AND LEAD IN AQUATIC PLANTS AND BOTTOM SEDIMENTS OF ANTHROPOGENIC RIVERS

1. INTRODUCTION Contamination of aquatic environment by heavy metals has become a serious concern in a developing world. Heavy metals, unlike organic pollutants, are persistent in nature and cannot be biologically destroyed. They can only be transformed from one oxidation state or organic compound to another.These metals are released from variety of sources such as mining, urban sewage, smelters, tanneries, textile industry and chemical industry. Heavy metals are highly toxic to aquatic plants

FABRICATION AND CHARACTERISATION OF CHITOSAN/COCONUT FIBER COMPOSITE MEMBRANES FOR ELIMINATING CU2+ AND PB2+ FROM AQUEOUS SOLUTIONS

1. INTRODUCTION Heavy metals play an important role as “trace elements” in biochemical reactions and are essential elements for the body in low concentrations [1]. However, at higher concentrations, heavy metals cause serious toxicity. When heavy metals enter the human body, they affect the sulphate groups in enzymes, enabling enzymatic deactivation or membrane blockade, preventing the transport of materials through the cell membrane and metabolism, potentially resulting in poisoning. In

CADMIUM AND LEAD CONTENT IN THE BARRIER DUSTS SAMPLED FROM THE NOISE BARRIERS LOCATED NEAR TO POZNAŃ (POLAND) - A PRELIMINARY STUDY

High levels of heavy metals in the environment are dangerous for humans due to possible bioaccumulation of such contaminants by edible plants and herbivores. In this study, total content of cadmium and lead in the barrier dusts sampled from three noise barriers located along E261 expressway in Poland (near Poznań) was determined using flow-injection differentialpulse anodic stripping voltammetry (FIA DP-ASV). The results indicate that total content of the studied metals ranged from 0.09 to 0.6

BACTERIAL METALLOTHIONEINS

Heavy metals are found in all living organisms where, as indispensable microelements (e.g. zinc, iron, copper), are involved in endless metabolic processes. However, living organisms are also at a risk of exposure to highly toxic metals, including cadmium or lead, which do not play any physiological role. Among multiple mechanisms associated with the maintenance of micronutrient homeostasis and detoxification of unwanted metals, there is a family of low-molecular-weight, cysteine-rich proteins

Enterobacter asburiae KUNi5, a Nickel Resistant Bacterium for Possible Bioremediation of Nickel Contaminated Sites

Nickel resistant bacterial strain Enterobacter asburiae KUNi5 was isolated and showed resistance up to 15 mM and could remove Ni opti­mally better at 37°C and pH 7. Maximum removal was found at initial concentration of 0.5 to 2 mM, however, growth and Ni removal were affected by other heavy metals. Major amount of the metal was accumulated in the membrane fractions and certain negatively charged groups were found responsible for Ni binding. KUNi5 could also produce 1-aminocyclopropane-1

ECONOMIC ASPECTS OF APPLICATION OF PRETREATMENT SYSTEMS BEFORE GRANULAR ACTIVATED CARBON FILTRATION

Granular activated carbon (GAC) is used for removing an excessive amount of organic contaminants causing undesirable taste, odour or colour of water, and refractive micropollutants, such as heavy metals or toxic organic compounds. However, adsorption is one of the most expensive unit processes used in treatment and renewal of water. This is due to the high cost of granular active carbon and the necessity of its frequent exchange or regeneration. In the paper the authors present the results of

Natural Attenuation Potential of Polychlorinated Biphenyl-Polluted Marine Sediments

The marine environment in Kuwait is polluted with various hazardous chemicals of industrial origin. These include petroleum hydrocarbons, halogenated compounds and heavy metals. Bioremediation with dedicated microorganisms can be effectively applied for reclamation of the polluted marine sediments. However, information on the autochthonous microbes and their ecophysiology is largely lacking. We analyzed sediments from Shuwaikh harbor to detect polychlorinated biphenyls (PCBs) and total

Levels of Organic Compounds, Number of Microorganisms and Cadmium Accumulation in Festuca ovina Hydroponic Culture

Understanding the microbiological, biochemical and physiological aspects of phytoremediation of soil and water environments polluted to different degrees with heavy metals has very important theoretical and practical implications. In this study, a comparison was made between total cadmium concentration in root and shoot tissues as well as concentrations of particular fractions of Cd immobilized by roots of Festuca ovina (Sheep’s fescue) hydroponically cultivated in nutrient solutions
