Bad air pollution and ill health effects -by- Naseem Sheikh

Air pollution is a mixture of solid particles and gases in the air released both by natural and anthropogenic sources. Natural sources includes volcano eruption, soil erosion, wildfire, pollen and mold spores and volatile organic particles evaporation of mountain and sea salts due to high temperature. Anthropogenic sources includes traffic vehicle emissions, chemicals from factories, fumes of volatile organic compounds from hair spray, varnish, air freshener, body spray and other solvents, chemicals from fertilizers,controlled burn particles from agriculture and forests, hazardous waste gases from incineration and military weapon utilization. It may cause diseases, allergies and even death to humans; it may also cause harm to other wildlife and food crops, and may damage the natural or built environment.Some air pollutants are poisonous. Inhaling them can increase the chance of ill health problems. People with heart or lung disease, aged adults and children are at higher risk from air pollution. Air pollution isn't just outside - the air inside buildings can also be polluted and affect your health. Some 3 million deaths a year are linked to exposure to outdoor air pollution. Indoor air pollution can be just as deadly. In 2012, an estimated 6.5 million deaths (11.6% of all global deaths) were associated with indoor and outdoor air pollution together. Under developed and middle income countries are highly affected due to air pollution due to lack of protection barriers. Nearly 90% of air-pollution-related deaths occur in low- and middle-income countries, with nearly 2 out of 3 occurring in WHO’s South-East Asia and Western Pacific regions. Ninety-four per cent are due to noncommunicable diseases – notably cardiovascular diseases, stroke, chronic obstructive pulmonary disease and lung cancer. Air pollution also increases the risks for critical respiratory infections.Even in the areas with relatively low levels of air pollution, public health effects can be significant and costly, since a large number of people breathe in such pollutants. Air pollution is responsible for one in nine deaths worldwide, and touches everyone -- 92% of the human race live in places that do not meet World Health Organization air quality guidelines. This notorious developing cloud of pollution has catapulted air pollution towards the top of the list of avoidable risk factors for ill health, with an unacceptably high burden of disease. Climate change is a global phenomenon, its impacts not restricted to local place but in fact spread all over the world even to northern areas where population is very low. Climate change is affecting the health of living beings. As the climate continues to change, the risks to human health will grow, exacerbating existing health threats and creating new public health challenges. This assessment significantly advances what we know about the impacts of climate change on public health, and the confidence with which we know it. it has very local impacts that can profoundly affect communities, not the least of which is air pollution. Increasing temperatures are directly linked to poor air quality which, in turn, can affect the heart and exacerbate cardiovascular disease and even cancer. Due to outside bad air condition inner air situation is also not safe. in 1984, a World Health Organization report on Sick Building Syndrome (SBS) suggested that up to 30% of new and remodeled buildings worldwide may be linked to symptoms of SBS due to inner impure air conditions. Syndrome causes are frequently pinned down to flaws in the heating, ventilation, and air conditioning (HVAC) systems. Other causes have been attributed to contaminants produced from the off-gassing of some types of building materials, volatile organic compounds (VOC), molds, light industrial chemicals used within an office or home, or improper fresh-air intake location/lack of adequate air filtration.

AquaPonics: latest environmental and climate friendly way of gardening

Image
Aquaponic is a combination of two words, Aqua – water and Ponics-Farm in a box. “Aquaponics an environmentally-friendly, natural food growing method to facilitate the cultivation of fish and plants together in a constructed, re-circulating ecosystem utilizing natural bacterial cycles to convert fish wastes to plant nutrients. “So it is also called as recirculation farming. Recirculation farms are a socially responsible farming method and business too; they support the use of renewable energy, recycle water and waste, and provide local food. Aquaponic systems are much more productive and use up to 90 percent less water than conventional gardens. Other advantages include no weeds, fewer pests, and no watering, fertilizing, bending, digging or heavy lifting etc. there are different types of aquaponic like Media Bed - (using a substance such as lave rocks or other medium other than soil for raising plants and bacteria) Raft - (using foam boards with cut outs to place planter pots floati...

Nipah Virus infection is zoonosis, chicken are also indirectly involve

Image
Now a days various messages on social media warns Pakistani nation to avoid chicken consumption, because its source of Nipah virus, In Pakistan production of poultry products is very high to fulfill the consumption requirements. For Layman it is confusing and  debatable either chicken is source of Nipah virus or not, mostly said no its fake news, chicken is safe its not the cause of spread, other said avoid the chicken consumption because, prevention is better than cure. Nipah virus (NiV) infection is a newly emerging zoonosis that causes severe disease in both humans and animals. "Zoonosis means a disease that can be transmitted to humans from animals". Nipah virus was first identified in Kampung Sungai Nipah, Malaysia in 1998. The pigs were the intermediate hosts during that outbreak. Around 1.1 million pigs had to be killed to control the outbreak. However, it is not necessary to have an intermediate host during Nipah Virus outbreak. The natural host of ...

Precautionary measurements in the event of an earthquake-by-Naseem Sheikh

Image
Here are some of the precautions that can be taken to minimize the potential loss of execution. With these measures and premature awareness, we can prevent earthquake damage. [caption id="attachment_media-133" align="aligncenter" width="289"] Photo by rawpixel.com on Pexels.com [/caption] Control your senses if you feel an earthquake. Instead of panicking, jumping from the top floor and screaming without panic, they can easily get out of the building so it is better to stay where they are. Cover your head with your hands with both hands, and sit down in a corner instead of the middle of the room. If there is a strong table or bed, seek shelter under it. If no heavy furniture is nearby, seek shelter under the door frame or under the stairs, as the doors sometimes jam with jerks. When in the kitchen or in the lab, close the valve as soon as the shock is mild, try to get out. If you're on the top floor, don't go down the stairs during the tremors...
