The Functions of Water probably heard of water, but how do you understand what it is? It’s a complex liquid made up of molecules. A large drop of water contains about 3 billion trillion molecules! A single molecule of water has three atoms: two hydrogen atoms locked in a triangle with one oxygen atom. These three atoms form the chemical formula H2O. The slightly-unbalanced structure of water molecules allows them to dissolve and attract many different substances.
Molecular structure
The molecule of water is composed of hydrogen and oxygen atoms. These two atoms are connected by electrons, and their mutual attraction creates covalent bonds. These bonds have a weak attraction, but they are very important in the chemistry of life. Some molecules have a high affinity for water, while others have an antipathy towards it. These are referred to as hydrophilic and hydrophobic molecules, respectively.
The water molecule is made up of two hydrogen atoms, one of which is connected to an oxygen atom by a single chemical bond. The hydrogen atoms in water have solely proton nuclei, except for deuterium and tritium, which contain two neutrons. The latter is called heavy water and is used for chemical research and in nuclear reactors. This study has significant implications for understanding the structure of proteins and other biomolecules in aqueous solutions.
Functions
Listed below are eight fundamental functions of water, each operating at a different spatial scale. Water for supply and state primarily function at the local or regional scale, while the carrier and productive functions extend well beyond the local watershed. The regulatory function of water has global implications, while green water functions may have only local implications, but can still have large impacts through atmospheric processes. In the context of sustainability and resilience, water’s functions are essential for achieving these goals.
Understanding water’s functions allow scientists and policymakers to identify the most appropriate policies for future environmental and human security. Water provides essential resources for human life. As one of the most essential elements of our physical and chemical systems, water plays an essential role in maintaining ecosystem balance. From simple diffusion of food substances to complex chemical reactions, water facilitates human activity and plays an important role in regulating temperature and acid-base balance. Water is the main component of blood, urine, sweat, tears, mucus, and joint fluid.
Sources
Humans have varying methods of extracting water from various sources. Some sources are natural and others are man-made. For example, the surface water is collected from rainfall, while dams and reservoirs produce hydroelectric power. Rainwater is a valuable water source on a small scale, and rainwater collection and storage can be very beneficial. In BYJU’s Biology course, students will learn about water and its sources.
Many factors must be considered when selecting a source of water. Over-extraction and pollution of water can reduce availability. Global water consumption is increasing, primarily due to increased population and per capita consumption. Developing countries use less water per person than industrialized countries. The availability and sustainability of freshwater sources can determine whether a community has clean water supplies. However, the amount of water that can be extracted from the ground is limited. Water conservation efforts can improve water quality and supply in low-income areas.
Adaptability
The global north has lost sight of its ability to adapt. In the past, we have successfully mitigated floods and storm surges by building on high ground and implementing major infrastructural systems. Today, we face unprecedented challenges of climate change, which threatens this engineered security. In response, our policymakers are integrating climate change into the water sector and examining how we can adapt to these new challenges. Here are the three key elements of a successful adaptation strategy.
Firstly, we must accept that the supply of water is not the same in all areas. This will require us to accept that water can be recycled and reused. This is the transition phase from the efficiency of water supply to the adaptability of water demand. Water management in this phase requires new approaches, including increased collaboration between the public and private sectors. By identifying the critical elements of water governance, we can create a more efficient water supply and balance direct and indirect benefits.
Health risks
Exposure to trace metals in drinking water may increase the risk of developing cancer, particularly in children. Long-term exposure to toxic metals causes various forms of cancer. Health risks of drinking water by metals are listed in Table 11. The carcinogenic risk is less than one x 10-6; higher values are harmful. Listed below are the health risks of different trace metals found in water. The levels of these chemicals are acceptable in some areas.
The sources of contamination are not always clear. For example, contaminated water can be the result of poor land-use practices, unmanaged sewers, or even organic chemicals. Even if the drinking water is purified and tested, it is still possible to have some contamination. In addition to bacterial contamination, drinking water can contain other contaminants. In some areas, the government regulates bottled water. Private good owners may also want to collect additional samples. Visit this Website to get more information.
