Air Pollution – Heart Related Hazards
Air Pollution – Heart Related Hazards
We know that what we’re looking at when brown haze settles over a city, exhaust billows across a busy highway, or a plume rises from a smokestack. Some air pollution is not seen, but its pungent smell alerts for you.
According to The American Heart Association, someone dies from cardiovascular disease every 40 seconds in the United States. Almost half of an Americans have at least one of three main risk factors for heart disease, high blood pressure, high cholesterol, and a smoking habit. Doctor’s tells their patients to exercise more, watch what they eat, and to quit smoking to lower their cardiovascular risk, but there are other factors that we should be also recognize as having an impact on our heart health, like air pollution exposure.
An association between the high levels of anthropogenic air pollutants and human illnesses has been known for more than half of a century. A few episodes of markedly increased of mortality rates during extreme elevations in urban pollution.
Air Pollution – Heart Related Hazards
Each year, an American Heart Association, in conjunction with the Centers for Disease Control and Prevention, National Institutes of Health & other government agencies, compiles up-to-date statistics on heart disease & other Heart vascular diseases.
Pollution can come from traffic, factories, power generation, wildfires or even cooking with a wood stove. One of the most common indoor sources is smoking, a dangerous to the person lighting up and to those nearby.
MESA
MESA Air provides evidence that the long-term exposure to air pollution is a cardiovascular disease risk factor, that should be taken as seriously. In addition of encouraging policy makers to consider as the long-term impacts of low levels of air particle pollution and motivating healthcare providers to the effects of air pollution on the cardiovascular system, the study emphasizes the importance of monitoring air quality to protect heart.
People are breathing in air pollution like carbon monoxide and particulate matter, which are tiny air particles composed of noxious substances. Some researchers are concerned about particulates that is 2.5 micrometers or smaller, which is most commonly found in car exhaust. The small size of these particulates are allows them to easily enter the body and poses a greater risk to the circulatory system than other common pollutants.
Medical researchers are particularly concerned about pollution particles smaller than 2.5 microns, which are usually related to fuel combustion. Because they are so tiny, they aren’t easily screened and more readily enter the human body. Then they begin to irritate the lungs and blood vessels around the heart. Data suggests that over time pollutants aggravate or increase the process of disease in the arteries.
Avoiding Air Pollution when You Have a Heart Condition
While it is nearly impossible to avoid all the forms of air pollution, it is recommended that heart disease patients avoid spending a long periods of time in areas of high pollution, such as near busy roads, factories or railways.
Being physically active can be improve heart and circulatory health, but consider reducing the amount of exercise have done outdoors if the air pollution in your area is high.
Epidemiology studies have used blood and urine to look for mechanistic markers for the cardiovascular changes.
Range
- 6.9 percent increase in out-of-hospital cardiac arrests, with a stronger association between the pollution and cardiac arrests in men and people 65 and older.
- 2.07 percent increase in emergency department visits for ischemic heart disease.
- 1.86 percent increases in hospitalizations for ischemic heart disease, with a stronger association in women and people 65 and older.
- The risk of death is greater from long-term exposure. Current science suggests air pollution facilitates atherosclerosis development and progression, said the scientific panel that worked on the statement. It also may play a role in high blood pressure heart failure and diabetes.https://youtu.be/d9K6JqFBrvA
Pandemic Situation has Affects the Air Pollution
Pandemic Situation has Affects the Air Pollution : The outbreak of COVID-19 has created a global health crisis. Most of the countries in the world have been affected by COVID-19 infections. However, some regions have been more badly affected in terms of infections and fatality rates than others. These remarkable variations have raised significant questions related to the influence of air pollution to the extent of COVID-19 infections, and its mortality rate around the world.
Pandemic Situation has Affects the Air Pollution : We know that air pollution can cause health problems, like heart attacks, strokes, diabetes and high blood pressure, that have been identified as the pre-existing medical conditions that to raise the chances of death from COVID-19 infection. Recent study made by Harvard T.H. Chan concluded that breathing more polluted air over many years may itself worsen the effects of COVID-19.
According to the World Health Organization, air pollution kills an estimated seven million people worldwide every year. Almost 99% of the global population breathe air that exceeds of guideline limits on pollutants.
Air pollution kills an estimation of seven million people per year, according to the World Health Organization
How lockdowns affected air pollution
We know that air pollution can cause health problems, like heart attacks, strokes, diabetes and high blood pressure, that have been identified as the Pre-existing Medical conditions that raises the chances of death from COVID-19 infection.
Country by country, region by region, the emergence of the coronavirus changes a life as we know. Entire populations were locked down and forbidden from the travelling of anything but essential and emergency purposes. Data from the International Energy Agency showed as the, by the end of March 2020, global road transport activity fell by almost 50% year on year.
While the study does not show that the air pollution directly affects an individual’s likelihood of dying from COVID-19 because individual-level of COVID data’s are not yet publicly available, it does show an association between long term exposure to air pollution and higher COVID-19 mortality rates of that pandemic Situation has affects the Air Pollution.
Hope for a cleaner future
It’s hoped that our brief experience of cleaner air will drive our desire to keep it. While pausing leisure and economic activity isn’t a healthy way do it, these shutdowns can offer valuable lessons moving forward.
Particulate matter can cause a variety of health concerns, and persons who already have a lung or heart condition are more likely to be harmed. The size of a pollutant particle is thought to determine the harm it poses to the body. This way the pandemic situation has affects the Air Pollution.
Although in cities and large towns like Glasgow, Warrington and Oxford, NO2 concentration levels more than halved during lockdown, not at all cities and large towns experienced a significant improvement in air quality.
prevention
- Wash hands frequently, use a sanitizer and maintain a physical distance of at least 2 meters.
- Use as a good quality mask, preferably an N95, N99 or N100 mask as they have the ability to filter out the finest particles.
- Patients who have recovered from the COVID-19 must be extra cautious as the disease tends to decrease lung function and increased level of pollution may aggravate their health problems.
- People must try to remain indoors and non-step out of their houses unless necessary.
- Early morning jogs must be avoided as their pollution levels are at a peak during those hours.
- When restrictions were lifted, air pollution returned to its pre-pandemic levels in 39 of 49 cities and large towns studied, even though none had returned to previous levels of economic activity.
- The coronavirus pandemic has been lead to an increase in air quality all around the world. Lockdowns have the resulted in factories and roads shutting, thus reducing emissions.https://www.apzem.in
SCRUBBER
Scrubber https://www.apzem.in
A scrubber or scrubber system is a system, that is used to removed harmful materials from industrial exhaust gases before they are released into the environment.
Spray Scrubber
Spray scrubber can be used to capture a particulate matter of size 2 microns and large particulates. It can be also remove gaseous pollutants. Apzem is a leading manufacturer of spray tower scrubber in India. Apzem’s wet spray scrubbers is incorporating standard design features and so it is extremely compact and can be easily customized based on the requirements.
Applications:
- Chemical industries
- Pulp & paper industries
- Petrochemical industries
- Steel making
- Corn Processing Facilities
- Food Manufacturing
- Pharmaceutical industries
A Devices called as a wet scrubbers trap suspended particles by direct contact with as spray of water or other liquid. In that effect, a scrubber washes the particulates out of the dirty airstream as they collide with and are entrained by the countless tiny droplets in the spray.
Working of Spray Scrubber
A scrubber is a cleaning installation whose main purpose is to neutralize harmful components in industrial air or waste gas streams. The removal of gas particles causing many problems from the gaseous stream during the process is necessary before disposing of the gases in an open air.
In some cases, the use of a gas scrubber may allow recovering a certain raw material after the treatment. A big advantage is the versatility of the gas scrubber in different areas. It includes the chemical industry, the pharmaceutical industry, and the surface treatment.
The installation functions by bringing the gas stream in contact with as washing liquid. Due to this contact, certain gaseous components are dissolved and remain in the water.
There is an transfer of the components from the gas phase to the liquid phase. This is a absorption process. The solubility of the elements in the liquid will determined to what extent the gaseous components dissolve into the liquid phase.
Thus it is a great importance to work with the correct fluid being as the absorption agent. Also besides the water, several organic or inorganic washing liquids can be also used for this purpose
In these causes, certain chemicals or micro-organisms are added to the washing liquid in order to convert or neutralize the dissolved gases.
When we use as scrubber in an optimal manner, we can achieve a very high removal efficiency of the harmful gas particles. Therefore, the fumes are released in the outside air are no longer damaging to the environment.
Purpose of Scrubbers
Scrubber systems are used as air pollution control devices that removed harmful particles, gases, or chemical byproducts from industrial exhaust streams. While not found on a many older industrial chimneys, new government regulations are requiring them to be added or constructed as an emissions control device.
Advantage
Scrubber can be classified by their use and the method they use to remove particulates. The main advantages of scrubbers is the continual use of the cheaper bunker fuel than low Sulphur fuel and thereby reducing the switching cost to an entirely new fuel system
A scriber is a hand tool used in metal work to mark lines on work pieces, prior to machining. The process of using a scriber is called as scribing, and is just part of the process of marking out.

Soldering Fume Extractor
Soldering Fume Extractor
solder : Solder is used by the assembly workers in many industries to make electrical connections and seal copper pipe during plumbing installations. It is typically available in a wire made from various metals with a core of flux on the inside. Soldering is accomplished by heating the two items to be connected with a soldering iron and touching the heated points with the solder, which melts, flows and solidifies to form a permanent connection. Flux helps to prevent the oxidation during the soldering Fume Extractor process.
Solder fumes
Solder fumes are composed of metal vapors from the solder and gas from the evaporated solder flux .Soldering melts metal alloys with low melting points to create a bond, releasing metal vapors into the air. When using an solder flux, the soldering irons are heats the solder flux to aid in the bond formation, turning the solder flux into a gaseous state.
This combination of the exposure to solder vapors and gases can cause the operator lasting health effects depending on the type of solder and the solder flux as well as duration the frequency of the application of Soldering Fume Extractor.
Fumes are generated during metal welding have toxic effects on the human body. The types and quantities of such effects depend on the density and duration of exposure time to the fumes. Moreover, the types of fumes generated during welding or Soldering is dependents on the electrodes or wires used. These fumes cover a wide spectrum from formaldehyde to metal fumes such as lead and Sternum.
Exposure to such a pollutants, particularly insufficient ventilation of workplaces increases the concentrations of fumes in the breathing air and hence can increase health risk factors.
Early symptoms of the fume exposure can include:
- Watering, irritated eyes
- Runny or Stuffy nose
- Throat Pain
- Coughing
- Wheezing
In addition to proper ventilation, employees must wear proper PPE to protect themselves from other soldering hazards. Protective clothing are such as a long-sleeved shirt, pants, and gloves prevents burns from splashes of hot solder. Protective eyewear, such as a safety glasses or goggles.
Effects of Soldering Fumes
- The dangers of carbon monoxide are very well documented and formaldehyde has been linked to causing serious breathing problems, has been linked to cancer, Amyotrophic Lateral Sclerosis (ALS), damage to the nervous system, nausea, vomiting, mood changes, depression, insomnia, etc. The list goes on.
Solid particulates are no matter how “non-toxic” or “clean” they are, are still foreign bodies in your lungs. The largest particulate in the solder fume is around 10 microns and the smallest is around 0.3 microns. The average human hair is around an 100 microns and human eyes can see below 30 microns unaided.
This means that the solid particles are fine dust, basically are small enough to pass into your lungs into the soft tissues and gas exchange chambers. Here it becomes lodged, and here it causes irreparable damage to your lungs.
Interstitial Lung Diseases (ILD’s) are a common effect of long-term exposure to dust particles that get into the deep workings of your lungs.
Soldering fumes are occupational health hazard caused by heavy metal vapors that can be breathed in.
- Proper ventilation throughout the shop in key.
- Fume extractors should be always used at soldering workstations.
- Personal protective equipment (PPE) will prevent contact with the heavy metals that could cause toxicity.
Soldering Fume Extractor – Safety Steps : Wear safety glasses or goggles whenever you solder a spatter of 370 °F molten metal or 300 °F boiling flux in the eye will ruin your day, week, etc. Use an fume extractor or noxious organic fume mask to keep the vaporized flux out of your lungs.
First Aid
-
- Any burns should be immersed in cold water for 15 minutes right away.
- If they wound is deep or extensive, seek medical attention. otherwise, cover it with a plaster or band aid.

Welding Fume Health EFFECTS
Welding Fume Extractor – Welding
Welding metals containing cadmium, chromium, lead, manganese, and nickel poses health risks to anyone who breathes the air when these fumes are present. The Environmental Protection Agency (EPA) has new requirements to reduce air pollution from compounds of these such metals.
Welding Fume
.https://www.apzem.in/index.php/product-category/fume-extractor/welding
These compounds are emitted into the air from various operations at metal fabrication, finishing plants. Exposure to the different types of welding fumes may result in different health effects. If a welder inhales gases, fumes and Vapors in large quantities over long periods, this may have a negative effect on his health.
Welding Gases
Vapors or fumes can come from coating and residues on metal being welded. Some ingredients in coatings can have toxic effect. These ingredients include: metalworking fluids, oils, and rust preventatives.
Zinc on galvanized steel (vaporizes, releasing zinc oxide fumes) Cadmium plating Chromate shielding gases such as carbon dioxide, argon, helium, etc. fuel gases such as acetylene, propane, butane, etc. oxygen used with fuel gases and also in small amounts of some shielding gas mixtures.
Welding Fume Effects
- Irritation of the welding tract Metal fume fever Sideris chronic inflammation of the lungs An increased risk of lung cancer Some of the components of welding fume, such as oxides of chromium, nickel, cadmium, and manganese are known as suspected carcinoma.
- A stainless steel welding fume has a higher content of these alloying elements like (as well as carbon) than mild steel welding fume does the former was thought to be significantly more hazardous. What the IARC discovered in that while mild steel welding fume contains much lower concentrations of these elements the concentrations is still potent enough to cause cancer in humans.
- The nose typically filters and collects much to the smoke, fumes, and grinding dust welding machines create. But some welding fume particles is very small in size and can pass through the nose, the sinus cavity, down the throat, and into the lungs.
- Most people never even notice an irritation. After a years of inhaling welding fumes, you begin to exhibit signs. Cause The most plausible theory involves an immune reaction that occurs when inhaled metal oxide fumes injure to cells lining the airways.
- This is thought to modify proteins in the lung. The modified proteins is then absorbed into the bloodstream, where they act as a allergens. It is usually associated with inhaling zinc fumes, although some believe that copper and magnesium can also cause the problem.
- Welding joins materials together by melting of a metal work piece along with a filler. Metal to form the strong joint. The welding process produces visible smoke that It contains harmful metal fumes and gas by-products. This fact sheet discusses about welding. operations, applicable OSHA standards, and suggestions for protecting welders and Coworkers are protected from exposure to the many hazardous substances in welding fume.
- Gases and fine particles in welding fume can cause dryness of the throat, coughing or tightness in the chest. This effects tend to be short-lived.
Welding Fume Extractor
Welding fumes are combination of various metals. For instance, mild steels are mostly iron, but it also contains a manganese, which has received a great deal of attention recently in terms of its effect on health. Stainless steels are also contains iron, as well as nickel and chromium. Simple steps can minimize exposure. Use any provided ventilation system (Welding Fume Extractor). Don’t stand in front of the air flow pushing fumes away from your workspace. Position your face as far from the fumes as possible. Use an small cooling fan if no air flow moves fumes from your workspace. https://www.apzem.in
