Type of Pollution and Human Health

Pollution is the introduction of contaminants into the sources we got from the nature. Without contaminants our natural resource are very clean and therefore we love to use these. Generally pollution is categorized into air pollution,  water pollution, noise pollution, soil pollution, radioactive pollution, thermal pollution (sometime also termed as heat island effect) and light pollution.  


Below photograph clearly shows the air pollution in terms of smoke. Air pollution can be by many means as it depends on various parameters. Moreover the reason of this kind of pollution is of inefficient system or un-burnt fossil fuel. Pollutants have a negative impact on the natural resources that we have in our world.

Air pollution is called when its chemistry get affected by pollutants. Pollutants may be in the form of particulate matter such as PM10 or PM2.5 etc. and dangerous gases such as carbon dioxide, Sulphar dioxide - SOx, NOx, dust or gases emitted by automobiles and form industries of various types. 
All these pollutants affect the human health greatly and continuous inhaling of these gases may vanish the human life. These affect the kidney, and other micro organism of our body. 
The list of pollutants are mentioned below - 
  • Pollution from automobiles  (train, car, bus, plane, etc.) - emission of various hazardous gases 
  • Sometimes due to fire in forest, volcanic eruption etc. 
  • Emission by Diesel Generator, commonly called DG sets (generally used for power backups) and energy system used during construction/ demolition of buildings/construction activities

Effect of air pollution can be easily observed on human health -  
  • Air pollution increases smog,
  • It may cause Acid rain
  • May cause Asthma
  • It causes Global Warming
  • many others are observed by us

Below image was taken at Sambhar Lake, Rajasthan. The process involved in this factory is to purify & refine the Salt - Sambhar Salt. There was complete black some which indicate un-burnt fuel or very very inefficient process of purifying Salt. 



Effect of air pollution:
1. CO2 (Carbon die-oxide) increases in the environment which affect the human health.
2. Indoor air quality suffers (hard to meet the ASHRAE 62.1 guidelines to meet the CO2 level in         the occupied areas)
3. There are many more .....to come shortly

Water pollution:
whenever poly bags, paper or contaminants get involved into either stable or flowing water then obviously it would be water pollution.

What is adaptive thermal comfort ?

Image
Overview Field studies of thermal comfort have been conducted intensively at various climatic locations to define the range of acceptable thermal environment for air-conditioned and naturally conditioned buildings that led to the development of Adaptive Thermal Comfort (ATC) model.  Research on adaptive thermal comfort revealed a higher range of acceptable temperatures, which depend on climate, building type, behavioral controls, and other similar factors. Field studies have also revealed the role of thermal adaptation to conserve energy in air-conditioned buildings, and this concept is also useful for building design, and operation of naturally conditioned buildings as per the outdoor conditions.  Higher bandwidth of comfort temperature and energy conservation opportunities encouraged researchers to carry out intensive field studies of thermal comfort to propose robust adaptive thermal comfort model. Definition Adaptive principle states that if a change occur...

ISO 7730 for Thermal Environment Evaluation

ISO 7730 is an International Standard for 'Ergonomics of the Thermal Environment-Analytical Determination and Interpretation of Thermal Comfort Using Calculation of the PMV and PPD and Local Thermal Comfort Criteria’.  ISO 7730 illustrates methods to evaluate the general thermal sensation and the degree of discomfort for occupants exposed to moderate thermal environmental conditions. This Standard grouped the thermal environment into three different categories namely  Category-A,  Category-B and  Category-C  All there  categories  are described with the help of Table given below.  Category-A describes narrow comfort conditions, whereas Category-C prescribes wider comfort bandwidth (-0.7 < PMV < +0.7). The Standard describes the calculation of PMV and PPD indices for thermal comfort and for local discomfort. The Standard also defines the local clothing habits for indoor comfort and but does not provide information for cl...

EN 15251 for Energy and Thermal Environment Evaluation

Comfort standard EN 15251 (version released in 2007) is entitled to ‘Indoor environmental input parameters for design and assessment of energy performance of buildings–addressing indoor air quality, thermal environment, lighting and acoustics.’  The Standard EN 15251 deals with energy performance of buildings as well as indoor environment quality such as thermal environment, indoor air quality, acoustic comfort, and visual comfort conditions to provide more comfortable indoor climate and that is also energy efficient.  Previous research  (Nicol & Wilson conducted study in 2010)   has examined that EN15251 Standard helps building designers to optimise the building energy consumption, considering thermal, air quality, acoustic and visual comfort. Furthermore, studies carried out under SCATs (Smart Controls and Thermal Comfort) research project reveal that this Standard involve  only   European countries for energy and comfort evaluation. SCAT s...
