These heavy metals are found naturally on the Earth's crust since the Earth's formation. Due to the astounding increase of the use of heavy metals, it has resulted in an imminent surge of metallic substances in both the terrestrial environment and the aquatic environment [4]. Heavy metal pollution has emerged due to anthropogenic activity which ...
The mining industry contributes to several major sectors of the economy, including agriculture, energy, construction, transport and manufacturing. In 2004 the value of production from mining underground resources (excluding oil and gas) was $1.142 billion, just under 1% of gross domestic product. This had grown over 45% since 1999, buoyed …

Dec 10, 2017 0183 32 Zinc, like all metals, is a natural component of the Earth s crust and an inherent part of our environmentZinc is present not only in rock and soil, but also in the air, water, and the biosphere - plants, animals, and humans Zinc makes up an estimated 0004 of the Earth …
The environmental effects of dredging have come under scrutiny in recent years. Environmental organizations, in particular, have raised questions about dredging's effect on bank erosion, water quality, and wildlife. …
Abstract. We developed a simple aquatic microbial ecosystem model in order to examine potential effects of zinc on microorganisms and the related degradation of …
The aims of the study were to (1) explore the changes in the zinc toxicity effect on the aquatic organisms in environments with different pH values and (2) compare the short-term hazardous concentration …
Sulfur is an essential nutrient for crop production, often ranked behind only nitrogen, phosphorus, and potassium in importance. Increased removal due to higher crop yields combined with reduced inputs from atmospheric deposition and other sources have increased the prevalence of sulfur deficiencies. This Crop Insights discusses sulfur …
For more information on asbestos health risks Ph.D A serious and increasingly clear threat to coral Some effects of marine pollution are visible land and water are looked after by everyone in today's society 2020· 1. Introduction. The aquatic environment is composed of marine and freshwater ecosystems.
1. Introduction. Expeditious expansion and industrial development near the rivers have led to more stress on the river, and with increased stress, the water becomes polluted, and worsening environmental health is observed [].The water-soil interface and the water-atmosphere interface are the medium through which the heavy metals travel …
Tang, Xin, et al. presented a study on the environmental risks of zinc oxide (ZnO) nanoparticles exposure and their associated toxicity effects of freshwater algae Microcystis aeruginosa. When the organism was exposed to ZnO nanoparticles >1 mg/L, the destruction of the algae occurred including the release of the intracellular organic matter.
Analytical electron microscopy (AEM) was used to characterize individual aquatic particles in a lake that has been contaminated by zinc smelting operations. Samples were …
The toxic effect of zinc on aquatic animals depends upon several environmental factors, especially temperature, water hardness, and dissolved oxygen concentration. At an acute toxic concentration of zinc, it kills fish by destroying gill tissue and at the chronic toxic level, it induces stress which results in the death of fish [ 120 ].
Zinc potentiates the metabolism function, synthesis of essential enzymes, and the formation of hormones associated with growth, reproduction, …
Abstract. Bituminous materials are one of the oldest and most widely used construction materials. While their components are obtained from finite resources, these materials have long been known as sustainable products due to their capacity to extend their serviceable lives through reclaim, reuse and/or the recycling processes.
Introduction. Human activities are increasingly impacting the marine realm, often resulting in detrimental effects on the health and productivity of marine ecosystems [].Plastic debris is now recognized as an important anthropogenic pollutant, and plastic litter has now been found in all surveyed marine areas [].Plastics commonly found in the …
Negative effects on the environment are unequivocal and are occurring around the world. The volume being extracted is having a major impact on rivers, deltas and coastal and marine ecosystems, sand mining results in loss of land through river or coastal erosion, lowering of the water table and decreases in the amount of sediment supply.
Antibiotic residues in aquatic environments pose a potential hazard, and microbes, which play important roles in aquatic ecosystems, are vulnerable to the impacts of antibiotics. This study aimed to analyze the research progress, trends, and hot topics of the impact of antibiotics on microbial community and biodegradation mechanism using …
The same reasons that led this water to be so clear are the reasons certain quarries are well suited for use as reservoirs. Structural stone is waterproof. "Quarry" could be used as a catchall term for any sort of mine. Quarries for building stone are the ones to use. The Bellwood quarry depicted above was for granite.
Zinc-shortages can even cause birth defects. Although humans can handle proportionally large concentrations of zinc, too much zinc can still cause eminent health problems, such as stomach cramps, skin irritations, vomiting, nausea and anaemia. Very high levels of zinc can damage the pancreas and disturb the protein metabolism, and cause ...
The aquatic ecosystem has an emerging threat caused by microplastic as a result of dumping plastic into water bodies. Thus, resulting in degradation of the quality of aquatic sediments, which is assessed by the enrichment factor. The effect of pollution on sediments can be evaluated by "degree of pollution.".
The aim of this paper is to review the environmental effect of concrete industry. It has been found that the environmental impact of concrete industry is severe in various environmental categories ...
Zinc (Zn) is the second essential microelement, and it plays a variety of roles in their bodies, including protein and energy metabolism, gene control, cell membrane, and bone health [ 16 ]. Zn is a cofactor for more than 200 enzymes in animals' bodies, including alkaline phosphatase, carbonic anhydrase, and alcohol dehydrogenase [ 17 ].
Some of the chemical and physical properties of zinc and zinc-containing compounds are presented in Table 2-1. Table 2-1. s of zinc and selected zinc compounds Zinc Zinc oxide Zinc chloride Zinc sulfate Zinc sulfide CAS Registry Number Molecular formula Zn ZnO ZnCl2 ZnSO4 ZnS Molecular
In recent years, talks on toxic metal pollution had taken center stage in most scientific symposiums as a serious health concern. Very high levels of toxic metals have been reported in most parts of South African soils, plants, animals and water bodies due to pollution. Toxic metals such as Zinc (Zn), Lead (Pb), Aluminium (Al), Cadmium (Cd ...
Purpose Soils formed in metallic mines and serpentinite quarries, among other unfavourable features, have high levels of heavy metals. They can release into the environment causing surface and subsurface water contamination, uptake by plants, their accumulation in the food chain and adverse effects on living organisms. In this work, we …
