❑ More than 90% of skin lesions caused in the workplace are contact dermatitis.
Accurate diagnoses and identification of etiologies are necessary, not only to properly treat skin diseases, but also to prevent future occurrence of disease or exposure.įamiliarity with the vocabulary of dermatology is helpful in understanding this specialized topic. Seven common skin conditions that can have environmental etiologies are presented in this monograph. Dermatitis from chemical exposures in the workplace accounts for about 30% of all reported occupational illness the prevalence of skin lesions due to chemicals encountered outside the workplace (i.e., environmental exposures) may never be known. The large number of chemicals in the home and workplace and the accidental and intentional releases to air, water, and soil potentially allow ever-increasing contact with chemicals in the environment. Because the skin has such a prominent and protective role, many factors affect it adversely, including mechanical agents (friction, vibration, pressure, and trauma) physical agents (heat, cold, and radiation) biologic agents (plants, insects, animals, and microbes) and a variety of chemical agents. The skin ensures the body’s integrity by preserving internal fluids and electrolytes, maintaining thermoregulation, and protecting against physical injury and entry of harmful agents. The Nature of Water: Environment CanadaUnlike most organs, the skin is in constant contact with the external environment.Mitchell, H.H., Hamilton, T.S., Steggerda, F.R., and Bean, H.W., 1945, The chemical composition of the adult human body and its bearing on the biochemistry of growth: Journal of Biological Chemistry, v.No less important is the ability of water to transport waste material out of our bodies. The carbohydrates and proteins that our bodies use as food are metabolized and transported by water in the bloodstream. Water's "stickiness" (from surface tension) plays a part in our body's ability to transport these materials all through ourselves. The excellent ability of water to dissolve so many substances allows our cells to use valuable nutrients, minerals, and chemicals in biological processes.

The cells in our bodies are full of water. The unique qualities and properties of water are what make it so important and basic to life. There just wouldn't be any you, me, or Fido the dog without the existence of an ample liquid water supply on Earth. People with more fatty tissue have less water than people with less fatty tissue (as a percentage).Women have less water than men (as a percentage).Babies and kids have more water (as a percentage) than adults.In adult women, fat makes up more of the body than men, so they have about 55% of their bodies made of water.
However, fat tissue does not have as much water as lean tissue. In adult men, about 60% of their bodies are water. By one year of age, that amount drops to about 65%. Babies have the most, being born at about 78%. Jeffrey Utz, Neuroscience, pediatrics, Allegheny University, different people have different percentages of their bodies made up of water. acts as a shock absorber for brain, spinal cord, and fetusĪccording to Dr.It assists in flushing waste mainly through urination.The carbohydrates and proteins that our bodies use as food are metabolized and transported by water in the bloodstream.It regulates our internal body temperature by sweating and respiration.A vital nutrient to the life of every cell, acts first as a building material.Water serves a number of essential functions to keep us all going
All of the water a person needs does not have to come from drinking liquids, as some of this water is contained in the food we eat. Generally, an adult male needs about 3 liters (3.2 quarts) per day while an adult female needs about 2.2 liters (2.3 quarts) per day. Of course, this varies according to age and gender, and also by where someone lives. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%.Įach day humans must consume a certain amount of water to survive. Up to 60% of the human adult body is water.Īccording to Mitchell and others (1945), the brain and heart are composed of 73% water, and the lungs are about 83% water. Water is of major importance to all living things in some organisms, up to 90% of their body weight comes from water. Food? Water? Air? Facebook? Naturally, I'm going to concentrate on water here. Think of what you need to survive, really just survive. Water serves a number of essential functions to keep us all going
