2018-6-132007. Impact of Iron and Steel Industry and Waste Incinerators on Human Exposure to Dioxins, PCBs, and Heavy Metals Results of a Cross-Sectional Study in Belgium. Journal of Toxicology and Environmental Health, Part A Vol. 70, Strategies for Clean Air and Health, pp. 222-226.
2019-3-12Sulfidized zerovalent iron sZVI is widely studied because of its remarkable reactivity with a number of groundwater contaminants. Nonetheless, its nanoscale structure is not well understood. As such, there is an uncertainty on how sZVI structure controls its reactivity and fate in the subsurface environment. Using pair distribution function analyses, we show that sZVI made from one-pot ...
Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of sinkholes. The leakage of chemicals from mining sites can also have detrimental effects on the health of the population living at or around the mining site.
Dyeing and printing textiles can have a significant impact on the environment from discharge of dyes, pigments, and other chemicals into water systems. Components that contribute to problems include color, salt, acids, and heavy metals. Some materials create problems because of high biological oxygen demand others have high chemical oxygen ...
2008-2-25The impact of environment-related malnutrition has already been incorporated in the EBD estimates see for additional details relating to water, sanitation and hygiene in particular. No comprehensive database was, however, available for blood lead levels, and no methods for estimating the disease burden due to crowding had been developed at ...
Disposal of iron ore tailings along the shore of Tolo Harbour, Hong Kong has altered the adjacent environment. Due to the ever-expanding population, the vast development of various industries, and the lack of sanitary control, the existing pollution problem of Tolo Harbour is serious.
The iron and steel industry was the emblem of the industrial revolution in the 19th and early 20th century United States, playing an important role in shaping the nations transportation infrastructure, the industrial specialization of its cities,
The iron mining companies of Minnesota place environmental stewardship as company core values. Before any mining commences, Minnesota iron mines work with stakeholders, local, state and federal agencies thorough environmental reviews are conducted, and permits to mine include environmental control requirements.
2019-5-25To quantify the effects of an advanced iron photochemistry scheme, the chemical aqueous-phase radical mechanism CAPRAM 3.0i has been updated with several new FeIIIcarboxylate complex photolysis reactions. Newly introduced ligands are malonate, succinate, tartrate, tartronate, pyruvate, and glyoxalate. Model simulations show that more than 50 of the total FeIII is
When mining waste containing iron sulphides is allowed to lie unsheltered and comes under the effects of weather and wind, it will crumble through an oxidation process. This weathering results in the release of an acidic and often metal-rich leachate into the surrounding environment, known as
The impact of environmental issues on water supplies can result in harm to agriculture, a decrease in productivity, and higher costs. Mitigating Risk Environmental issues that we face today make it clear that solving as many of these complex issues as we can best serve all sectors.

The environmental impact of the Late Iron Age and Romano-British ironworking hillfort of Bryn y Castell in upland southern Snowdonia was investigated by multiple profile pollen and charcoal analysis of nearby valley mire and blanket peat deposits. Pollen data, collected from five radiocarbon dated profiles within a 1.5 km radius of the hillfort ...
2020-2-17The team developed a simple three-box model, with each box representing a general ocean environment with a particular balance of iron versus macronutrients. The first box represents remote waters such as the Southern Ocean, which typically have a decent concentration of macronutrients that are upwelled from the deep ocean.
