Environmental science is the study of the natural world and how it is affected by human activities. One important aspect of environmental science is the study of pollution, which refers to the presence of harmful substances in the environment. Pollution can have a variety of negative impacts on the environment, including air pollution, water pollution, and soil contamination. In this essay, we will explore some of the latest research on pollution and its effects on the environment.
One type of pollution that has received a lot of attention in recent years is air pollution. Air pollution refers to the presence of harmful substances in the air, such as particulate matter, carbon dioxide, and other gases. These substances can be emitted from a variety of sources, including power plants, vehicles, and industrial facilities.
Air pollution can have serious health consequences for humans and other animals. For example, exposure to particulate matter, which is made up of tiny particles suspended in the air, has been linked to respiratory and cardiovascular problems. Long-term exposure to air pollution has also been linked to an increased risk of cancer and other serious health issues.
Water pollution is another important issue in environmental science. Water pollution refers to the presence of harmful substances in bodies of water, such as lakes, rivers, and oceans. These substances can come from a variety of sources, including agricultural runoff, industrial waste, and sewage.
Water pollution can have serious consequences for the environment and the animals that depend on these bodies of water. For example, algae blooms, which are often caused by excess nutrients in the water, can lead to oxygen depletion and the death of fish and other aquatic life. Water pollution can also contaminate drinking water, posing a risk to human health.
Soil contamination is another type of pollution that can have serious consequences for the environment. Soil contamination refers to the presence of harmful substances in the soil, which can be caused by a variety of sources, including industrial waste, agricultural practices, and mining operations.
Soil contamination can lead to a variety of negative impacts on the environment. For example, it can lead to the death of plants and animals, and it can also contaminate the food supply if the contaminated soil is used to grow crops. In addition, soil contamination can have serious health consequences for humans, as the harmful substances can be absorbed through the skin or ingested through contaminated food or water.
In conclusion, pollution is a serious issue in environmental science, with a wide range of negative impacts on the environment and human health. From air pollution to water pollution to soil contamination, the presence of harmful substances in the environment can have serious consequences for the natural world and the animals and humans that depend on it. As such, it is important for individuals and communities to work towards reducing pollution and protecting the environment.

Such environmental impacts are increasing day by day because the scale of individual mining operations is increasing as mining of lower grade deposits increases. The present book, Assisted Phytoremediation, is aimed to offer such promising and potential tools to enhance plant performance. More than two-thirds of US adults now say they use technology to track their heart rate and other health data; gadgets for the home sense water and electricity usage by the minute, and cities are employing sensors to track everything from pedestrian traffic to leaky pipes. If the norms of developed countries are applied in India, costs will be very high. The WHO's online database for pollution has readings from just one year for Ulaanbaatar, showing concentrations of harmful particles called PM 10, which have a diameter of 10 micrometres or less, and PM 2.
In this direction, the plant-based remediation is appropriate to reduce contaminants. Parvaiz Ahmad, in Plant Metal Interaction, 2016 Abstract Environmental pollution is one the major problems that affects biodiversity, ecosystems, and human health worldwide by contaminating soil and water. Work is also under way to develop wearable sensors to monitor personal exposure levels. Many of the data produced by these devices are openly available through online platforms such as Xively. Pollution of air, water and land pose a serious threat to the well-being of every little thing that inhabit the Earth.
In May, a community effort coordinated by FutureEverything, an innovation lab in Manchester, UK, created a network of sensors around that city's centre. The problem is that temperature, humidity and some gases skew the results from sensors such as those used in the Air Quality Egg and SCK, making it difficult to compare results between devices, he says. Built on the principle of openness, such do-it-yourself DIY efforts are part of a push to democratize air-quality monitoring so that it no longer remains solely in the domain of governments and academic researchers. Around the same time, sensors for other uses were starting to emerge. Across the globe, journalists, advocacy groups, hackers and others are starting to use low-cost monitoring devices to vastly expand the amount of data that are publicly available on forms of air pollution such as particulate matter and toxic gases. The United Nations has also designated June 5 of every year to be World Environment Day in order to bring representatives of all member nations together to address the environmental problems, to create awareness and to instigate action. It is only then that they start thinking about doing something to stop the effects of pollution but little do they know that most of it are irreversible.
The answer to all the environmental problems the world is facing today is immediate action and consistency in reduced usage of private transportation, machinery with possible carbon emission and proper disposal of waste to start with. After spending a year looking at what technology was available, Díez Ladera decided that he and his team would have to realize this dream themselves. This can help modify microorganisms to gain the ability to sense and degrade hazardous chemicals from contaminated sites, in turn, allowing us to grow vegetation and improve crop productivity. Plants deploy multiple physiological, biochemical, and molecular mechanisms to counter the deleterious effects of environmental pollutants. Such pollutants as industrial effluents, automobile exhaust, domestic sewage, heavy metals, radioactive compounds, and various exhausts released by electronics remain in nature and pose great threats to the life on Earth. Da Costa had worked with engineers to develop the instrument package, which measured carbon monoxide and nitrogen oxides and tracked the pigeons' movements using a Global Positioning System GPS receiver.
In this chapter, conventional and advanced molecular biology tools for the removal and detoxification of contaminants from soil and water to improve environmental conditions are highlighted. Critical increase in health risks due to carcinogenic compounds by 20% is another effect of living in polluted habitats. DIY endeavours also lack input from pollution experts, says Tim Chatterton, a pollution-policy researcher at the University of the West of England in Bristol, UK, who has worked with the UK government to monitor air quality. It can be assisted by altering the environmental conditions and stimulate the microbial or plants grown for degradation or reduction of pollutants. In early 2014, officials in Amsterdam provided 100 citizens with SCKs and instructions on how to use them in their neighbourhoods. Holdgate 1979 defined environmental pollution as the introduction by man, into the environment, of substances or energy liable to cause interference with legitimate uses of environment. Article on Pollution Pollution is one of the most dangerous environmental problems the world is facing today.
Both developed and developing nations share this burden together, though awareness and stricter laws in developed countries have contributed to a larger extent in protecting their environment. Some environmental consequences of mining and processing coal deposits are deforestation, land damage, water pollution and hydrological damage, air pollution, noise pollution, ground vibration and rock dispersal, and visual impact. Using recent literature and a case study, we have elaborated the role of ecological pest management and industrial development that need to be focused toward sustainable environmental protection. During those rides, Apte found even greater fluctuation in the levels of harmful ultrafine particles, which are smaller than PM 2. Recent advances in CRISPR-Cas9 technology have been used to edit the genome of microorganisms or plants in order to improve the degradation and accumulation efficiency to a higher rate for controlling environmental pollutants. Apte's previous work has shown just how important it is to understand how pollution levels vary at the human scale. Multiple efforts have been taken by the governments of various countries and organizations around the world to reduce the effects of pollution on our environment.
This chapter examines the types of pollution—air, water, and soil; the causes and effects of pollution; and proffers solutions in combating pollution for sustainable environment and health. In 2013 the EPA announced the winners of a competition for developers to create low-cost wearable sensors that integrate air-quality measurements with health data. The sensors currently used in the SCK and the Air Quality Egg are not up to the task of providing robust pollution data, says Ben Barratt, an air-quality scientist at King's College London, who helps to run the London Air Quality Network, an online resource for pollution data. Moreover, these techniques help change or convert the pollutant from one form to another rather than completely degrading or removing it from the site Noel and Rajan, 2014. Soot fills the skies, and people don face masks to ward off smog so thick it can hide buildings a few hundred metres away. These efforts have already captured the attention of city officials and citizen groups. Similar efforts were emerging in Spain at around the same time.
Currently, advanced molecular biology tools along with conventional approaches allow us to rapidly degrade or accumulate hazardous materials from environments. Global warming is resulting into decline in world glacier reserves causing a noticeable rise of 3. Vimal Chandra Pandey, Vijai Singh, in Phytomanagement of Polluted Sites, 2019 Abstract Environmental pollution is one of the most serious global challenges. Human beings have the habit of taking things for granted. Hence, compared to conventional remediation practices, remediation with different kinds of plants or algae seems to be promising because of its low cost, eco-friendly nature, and easy implementation strategies.
All this enthusiasm by proponents has not yet won over environmental researchers. Phytoremediation is a cost-effective, environmentally friendly, nonintrusive, and affordable technological solution used to extract or remove inactive metals and metal pollutants from contaminated soil and water. Environmental pollution reflects a measurement of contamination of the living and nonliving physical and biological constituents of the earth, in a manner and to an extent, to adversely affect the normal optimum environmental processes Kemp, 1998. Water gets polluted when toxic substances like chemicals and plastic waste are discharged into the water bodies, and the process by which accumulated solid and liquid waste contaminate the soil and groundwater are referred to as land pollution. The pollutants may yield primary or secondary damages, of which the primary damage can be quantified and its impact monitored. In 2011, a group of hackers, makers and artists who called themselves the Sensemakers gathered at meet-ups in Amsterdam and New York. When winter descends on Ulaanbaatar, Mongolia, the air turns foul.
