Resumen

The more intensive growth of agricultural crops adding mineral fertilizers, environmental pollution make the soil degraded: reduce the fertility of soil, increase the concentration of heavy metals. Especially dangerous is a common, synergistic effect of heavy metals. Vermicompost optimizes pH, texture and organic material content – the soil indicators, which are the major contributors to migration of heavy metals in the soil and to the plants from it. In the article there is an investigation of vermicompost influence on bioaccumulation of heavy metals in common meadow-grass. After experimental

The paper analyses the effects of heavy metals on freshwater fishes. From the point of view of pollution caused by heavy metals, the condition of ecosystems in Lithuania is yet less affected by heavy metals compared to that the world over. Fishes accumulate heavy metals selectively. Fishes mostly accumulate Pb, Cr, Cd. Our experiments showed that MPC (Maximum Permitted Concentration) (0.2 mg/kg) of lead was exceeded 1.6 time in the muscles of perch, and 1.4 time ‐ in the muscles of roach. The MPC (0.05 mg/kg) of cadmium was exceeded 1.2 time in the muscles of perch and roach. It was determined

Resumen

Heavy metals normally occur in nature and are essential to life but can become toxic through accumulation in plants and living organisms. Arsenic, cadmium, chromium, copper, lead, nickel, and mercury are the most common heavy metals which can pollute the our environment. Most of the heavy metals causes environmental and atmospheric pollution, and may be lethal to plant. Heavy metal’s can become strongly toxic by mixing with different environmental elements, such as water, soil, and air plants and other living organisms can be uptake to them through the food chain.

Resumen

Intertidal sediments are rich in biological resources, which are important for material circulation and energy exchange. Meanwhile, these areas can be treated as sinks as well as sources of coastal heavy metal pollutants. Due to the influence of the tide, the intertidal sediments are in a state of periodic flooding and exposure, and environmental factors such as dissolved oxygen, salinity and overlying water pressure are changeable. Heavy metals in sediments are prone to migration and transformation with the dynamic effects of tidal water and the changes in the environment factors, which incre

Resumen

Biochar can be produced from many various feedstock including biomass residues such as straw, branches, sawdust and other agricultural and forestry waste. One of the alternatives is to obtain biochar from industrial sewage sludge, however, the use of such a product could be limited due to high quantities of heavy metals in the biochar as a product. Total concentration of heavy metals provides only limited information on the behavior of heavy metals, therefore, batch leaching and up-flow percolation leaching tests were applied to study the leaching of heavy metals (Cd, Pb, Cr, Ni, Zn, Cu) from

Essential heavy metals are needed in small amounts, such as Fe, Mn, Cu, and Zn, while non-essential heavy metals are heavy metals that are not needed by living organisms such as Cd, Pb, Ag, Hg, and Cr. Heavy metal management aims to reduce the negative impact of soil contamination due to heavy metals. One of the heavy metals management is using organic materials. Eco enzymes are the result of fermentation of organic materials that are rich in microorganisms. Microorganisms

Resumen

Heavy metals are substances that are widely present in the environment and are also used in human industrial activities. Heavy metals that cause major clinical problems include mercury, lead, arsenic, cadmium, and aluminum. Heavy metals can be exposed to humans not only through food but also through environmental media and household products. Although heavy metal exposure sources are managed by the Ministry of Food and Drug Safety, exposure may vary depending on the local environment or individual dietary habits. It is relatively easy to determine the cause of acute exposure of high-concentrat

Resumen

Heavy metals in organic fertilizers pose a risk to the agricultural ecosystem. The environmental risk of heavy metals depends not only on the total amount but also on the speciation. Hence, more information on heavy metals speciation in organic fertilizers is needed to avoid adverse effect. At present, the speciation information of heavy metals is usually obtained by the single-extraction method and sequential extraction method. Common heavy metals that have received attention include Cu, Zn, Pb, Cd, Cr, Hg and As. There is a lack of reviews on speciation analysis methods for heavy metals, spe

Resumen

Almost each heavy metal is serious toxicants as carcinogens. Heavy metals are kept under environmental pollutant category due to their toxic effects in plants, human and food. These are heavy metals persistence, accumulate and not metabolized in other intermediate compounds and do not easily breakdown in environment. Heavy metals are naturally occurring elements, and are present in varying concentrations in all ecosystems. Some of the heavy metals i.e. Arsenic (As), Cadmium (Cd), Lead (Pb), Mercury (Hg) are accumulative poison. Arsenic (As), cadmium (Cd), chromium (Cr), and nickel (Ni) are cat

Resumen

Environmental pollution due to heavy metals is a matter of great concern to many scientists and managers worldwide. The threats to human health from heavy metals are primarily associated with the exposure in agriculture production activities. However, a considerable number of technological methods have been used to remove the heavy metals from polluted soils. One of the simplest measures to effectively remove heavy metal contamination is to use both plants and microorganisms, which have been considered "natural materials" or "Bio-Materials" to treat pollutants. This study was conducted on asse

Resumen

Herbal medicines are potential sources of therapeutic aids for human beings. WHO estimates that 80% of the world’s population depends on herbal products as their primary form of health care. Herbal plants are widely used nowadays because they have few side effects, are readily available, and are cost-effective. Herbal plants are easily contaminated by absorbing heavy metals from soil, air and water. The primary health concerns of heavy metals are Arsenic, Cadmium, Lead and Mercury. Heavy metal causes countless health-related issues, such as kidney and liver damage, skin cancer, etc. So, the es

Resumen

The cultivation of rice is widespread worldwide, but its growth and productivity are hampered by heavy metals stress. However, sodium nitroprusside (SNP), a nitric oxide donor, has been found to be effective for imparting heavy metals stress tolerance to plants. Therefore, the current study evaluated the role of exogenously applied SNP in improving plant growth and development under Hg, Cr, Cu, and Zn stress. For this purpose, heavy metals stress was induced via the application of 1 mM mercury (Hg), chromium (Cr), copper (Cu), and zinc (Zn). To reverse the toxic effects of heavy metals stress,
