Broadly, long-term exposure to toxic heavy metals can have carcinogenic, central and peripheral nervous system, and circulatory effects. For humans, typical presentations associated with exposure to any of the "classical" [37] toxic heavy metals, or chromium (another toxic heavy metal) or arsenic (a metalloid), are shown in the table. [38]
Water pollution is a major global environmental problem because it can result in the degradation of all aquatic ecosystems – fresh, coastal, and ocean waters. [75] The specific contaminants leading to pollution in water include a wide spectrum of chemicals, pathogens, and physical changes
It is difficult to differentiate the effects of low level metal poisoning from the environment with other kinds of environmental harms, including nonmetal pollution. [36] Generally, increased exposure to heavy metals in the environment increases risk of developing cancer. [37]
The major effects of industrial air pollution on wildlife include direct mortality, weakening industrial-related injury and disease, and physiological and psychological stress. [15] Gas and particulate emissions from historical smelting operations have been a source of concern for human health and environmental impacts at some sites.
Legacy pollution or legacy pollutants are persistent materials in the environment that were created through a polluting industry or process that have polluting effects after the process has finished. Frequently these include persistent organic pollutants , heavy metals or other chemicals residual in the environment long after the industrial or ...
Mercury is a heavy metal that cycles through the atmosphere, water, and soil in various forms to different parts of the world. Due to this natural mercury cycle, irrespective of which part of the world releases mercury it could affect an entirely different part of the world making mercury pollution a global concern. Mercury pollution is now ...
Air pollution — Atmospheric particulate matter • Biological effects of UV exposure • CFC • Environmental impact of the coal industry • Environmental impact of hydraulic fracturing • Indoor air quality • Ozone depletion • Smog • Tropospheric ozone • Volatile organic compound • Ultrafine particles
The report Environmental Risks and Challenges of Anthropogenic Metals Flows and Cycles [1] was the third of six scientific assessments on global metals to be published by the International Resource Panel (IRP) of the United Nations Environment Programme. The IRP provides independent scientific assessments and expert advice on a variety of areas ...
