Ecological impacts of explosives are the effects that both unexploded explosives and post-explosion by-products have on the environment. [1] Explosive derived contaminants may have adverse effects on the environmental as well as human health. In addition to their military use in warfare, explosives are also used in construction and demolition.
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
Microparticles of destroyed ammunition shells may enter water and penetrate human and animal bodies through the food chain. [17] [medical citation needed] Explosives, such as TNT, DNT, and RDX, cause chemical pollution and induce acute intoxication and long-term mutagenic effects in people. TNT is easily absorbed through skin and mucous membranes.
A practical definition of water pollution is: "Water pollution is the addition of substances or energy forms that directly or indirectly alter the nature of the water body in such a manner that negatively affects its legitimate uses." [1]: 6 Water is typically referred to as polluted when it is impaired by anthropogenic contaminants.
Major current environmental issues may include climate change, pollution, environmental degradation, and resource depletion.The conservation movement lobbies for protection of endangered species and protection of any ecologically valuable natural areas, genetically modified foods and global warming.
The Department of Energy in 2022 required its existing sites to assess climate change risks to “mission-critical functions and operations,” including waste storage, and to develop plans to ...
Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
Water is the main transmitter of oil shale industry pollutants. One environmental issue is to prevent noxious materials leaching from spent shale into the water supply. [ 3 ] The oil shale processing is accompanied by the formation of process waters and waste waters containing phenols , tar and several other products, heavily separable and ...
