Environmental Pollution and it's Type


Have a glance at the spritzer nature at its excited best turquoise blue sky, an eyeful of green sparkling waters barraging wilderness and what about the land of vanishing beauty shrinking open space of gray concrete sooty air, drying land, dirty waters, and endangered wilderness. This change, which is named environmental degradation has become a serious issue before the planet. Let’s then begin with water pollution. Pollution is an undesirable change in the physicochemical or biological characteristics of air, water, and soil. Due to the addition of materials or energy in quantity, and quality which is harmful to living beings including man, thus substances that contaminate air, water, and soil are called pollutants. Pollutants may be gases like carbon monoxide, sulfur oxides, and nitric oxides. Metals like lead, zinc, and Mercury. Chemicals like aldehydes, detergents, pesticides, herbicides, and CFCs sewage radioactive wastes, and soon types of pollution are air, water, land, noise, and pollution.

Air Pollution-

The major causes of air pollution are toxic gases and exhausts that are let out into the air by industries, volcanoes, jet planes, automobiles, forest fires, burning of garbage, etc. these contain many harmful gases that cause diseases in human beings.

Water Pollution-

Destruction of vegetation and damage to the structures on earth, these gases can also form acid rainwater pollution the effluence let into water bodies from industries, sewage from towns and cities, washing clothes and cattle in water bodies and such other reasons cause pollution. The residual fertilizers and pesticides carried into water bodies during rain also caused pollution. The list of pollutants are often quite long oil spills and oceans are another major cause that harms marine life.

Land pollution-

If you wizard big cities you will find heaps of solid wastes. In around the sources of land pollution are mainly houses, cattle sheds, industries and agricultural fields. It includes household wastes, glass, fruit and vegetable waste. Dead bodies of animals, old clothes, paper, plastic bottles, cans, excreta chemicals, wood pieces and so on. The heaps of solid wastes provide a breeding ground for germs, in addition to spoiling the beauty and surroundings they Emmett, found smell controlling land pollution disposal of waste should be done very carefully and scientifically, it depends on the kind of solid waste.
Solid waste originating from constructing material etc. are varied in urban areas as landfills solid wastes like plastics, tin cans, metal scrap, a paper must be recycled, wastes originating from plant materials and household organic material can be became biogas and are often obtained from biodegradable wastes. Waste from hospitals and nursing homes should be burned in incinerators.

Soil pollution-

Pollution of soil is somewhat a localized phenomenon as compared to air and pollution, which spreads to long distances. Soil pollution occurs due to two main reasons, by pollutants that are washed down from the atmosphere because of rain, insecticides, and pesticides that are applied to the crops. Both these alter the composition and quality of the soil.

Noise pollution- 

Noise can be defined as any unwanted sound. Sound is measured in a unit called decibel dB. The lowest sound measured in this unit is 1 decibel and the sound of a rocket taking off is about 180 decibels, in-between the two are various levels of sounds. When we talk normally the sound level is about 60 dB, noise is a pollutant because it produces several adverse effects on human beings and other animal life. The loudness and duration of noise is injurious to our physical and mental health, sudden loud noise may cause acute damage to the eardrum, and continued loud noise may cause deafness. Now as low because the efficiency of labor disturbs, and causes irritability.

Thermal pollution-

Thermal pollution includes release of any quite heated gases or heated water repeatedly into the environment including the water bodies if released within the atmosphere they warm up the air therein area and if released in water bodies they kill aquatic life.

Office Ergonomics-Contact Stress: This Is What Professionals Do

Image
  Contact Stress- Contact stress results from occasional repeated or continuous contact between sensitive body tissue and a hard or sharp object contact stress commonly affects the soft tissue on the fingers, palms, forearms, thighs, calves and feet. Prolonged contact stress can inhibit blood flow, tendon and muscle movement and nerve function. One common example is resting wrists or elbows on the sharp edge of a desk or workstation, while performing tasks this can take place, while typing with the keyboard either too close or too far away using the mouse for a prolonged period of time can also lead to contact stress. The stress can be prevented by repositioning commonly used workstation items floating hands above the keyboard and reducing tension in the shoulders eliminates potential contact stress using a keyboard tray eliminates contact with a work surface edge and keeps your arms in a neutral position. Optimal neutral arm position has the arms relaxed at the side of the body with a

Different Types of Flanges and Valves in the Industry | Health and Safety

Image
Types of Flanges Flanges have been designed and developed to be used in countless application each one has its own special characteristics and should be carefully selected to meet specific functional requirements. The following flanges will be discussed in this chapter weld neck, threaded, socket weld, slip-on, lap-joint, blind, Orifice, and reducing flange. 1. Weld Neck Flange- Weld Neck Flanges transfer the stress from the flange itself into the connected pipe. These are used mainly for all processes and critical services where the weld joints need a radiographic inspection. 2. Socket Weld Flange-  Socket Weld Flanges are welded on one side only these are used for small board blanks only 3. Threaded Flange- Threaded Flanges are used on non-critical piping for air, water, or nitrogen. Usually, the piping material used for threaded piping is Galvanized CS. 4. Lap Joint Flanges- Lap Joint Flanges are used with stub ends. These are welded with pipes & fl

Hydrostatic Pressure Testing of Fire Extinguisher | Health and Safety

Image
We are going discuss hydrostatic test of stored pressure type fire extinguisher what you're going to see full hydrostatic test here, we wanted to give you guys a little bit of idea on how that works whether you are a fire equipment distributor or an end-user.  First, you need to take the extinguisher apart, then get the top off and then go ahead and clean off the tube then clean out the head of the extinguisher you can see there's a lot of foreign matter and dust particles and things inside, blow all that out, run a nylon brush through and then check that valve stem and the spring and make sure that everything is in good working condition. remember that the only difference between six-year care down and the hydrostatic test is simply that you need to fill that shelf full of water you need to pressurize it to three times its operating pressure and a hydrostatic test you need to record all that as opposed is just doing an internal examination and external examination o

Safety of Pressure Vessels and Pressure System

Image
  Pressure Vessels A pressure vessel consists mainly of a series of sheets of metal suitably shaped and welded together. They are designed to contain stored energy above atmospheric pressure. Pressure vessels, typically steam boilers and air receivers, are inherently potentially dangerous items of plant and there is a long and tragic history of accidents associated with them. -Typically injuries relate from: The impact from the blast of an explosion or release of compressed liquid or gas. Impact form parts of equipment that fail or any flying debris. Contact with the released liquid or gas, such as steam, and fire resulting from the escape of flammable liquids or gases; and Oxygen depletion or enrichment. -The typical causes of pressure system failure are: Poor equipment and or system design. Poor maintenance of equipment. An unsafe system of work. Operator error, poor training, and supervision. Poor installation: and Inadequate repairs or modification. St
