Causes of Water Pollution by Industries
One of the least discussed problems is sound pollution. People tend to underestimate this problem because it is not possible to smell, see or touch it. However, noise pollution also has negative effects on the environment and people. The research shows that many illnesses are connected to noise pollution, such as hearing loss, high blood pressure, coronary heart disease and speech interference. The industrial noises also affect the lives of animals. For example, whales’ navigation system breaks down due to the sounds of ships. Besides, the industrial noise makes wild species communicate louder which requires additional efforts and decreases their life spans.
Why Water Pollution by Industries should be Controlled
Essay on Air Pollution: Causes, Effects and Control of Air Pollution
These policies have been taken effects, and in 2015, the average PM2.5 in 74 key cities in monitoring system is 55 μg/m3, showing a 23.6% decrease as to 2013. Despite the reduction in coal consumption and polluting industries, China still maintained stable economic growth rate from 7.7% in 2013 to 6.9% in 2015.
Industrial Pollution Essay - Paper Topics
According to the World Bank, the Chinese cities with the highest levels of in 2004 of those studied were , , and . In 2012 stricter air pollution monitoring of ozone and PM2.5 were ordered to be gradually implemented from large cities and key areas to all , and from 2015 all or higher cities were included. State media acknowledged the role of environmental campaigners in causing this change. On one micro-blog service, more than a million mostly positive comments were posted in less than 24 hours although some wondered if the standards would be effectively enforced.
Free Pollution Essays and Papers - 123helpmecomMany inorganic materials take a long time to biodegrade, which means that their buildup rate is almost proportional to the total rate of pollution at any given time. These are also often some of the most potent and generally poisonous materials and thus strongly toxic even in low concentrations. Influential inorganic pollutants include non-metals like ammonia and cyanide and heavy metals such as Cu, Hg, Cd among others, which are all toxic in various degrees. Many inorganic discharges are point sources, so proper treatment of material is generally possible through biological degradation with microbes and fungi or electrokinetic treatment (the use of electricity to reduce heavy metal ions and turn them into elemental precipitates). Also, most heavy metals are much less toxic in alkaline environments, a fact that can be used in treatment plans. Some combination of these three techniques should be established to lower emissions for point source metal pollution.
Pollution by industries essayMacroorganisms, like mammals, amphibians, or fish, often have their own mechanisms of travel, yet even many of them need connected biomes. On the other hand, many smaller organisms that are essential to the ecosystem, such as small insects or microbes, cannot travel on their own and rely on wind, rain, drift, or transportation by other organisms to change places. Macroorganism travel may be significantly impaired by habitat fragmentation through , pollution of river biomes all the way to their sources, or an extinction or large reduction in numbers of transporting species such as waterfowl (Yukimura et al., 2009). These obstacles are also often directly correlated to the pollution or the cause of pollution. For instance, strong industrial presence can pollute environments, but will also lead to urbanization and habitat fragmentation due to workers living nearby. If there are no colonies preserved from pre-pollution eras and classical mechanisms of transport have been destroyed for organisms occupying important niches in the ecosystems, careful human intervention may be needed to introduce necessary species.
