8 Effects Of Environmental Pollution On Human Health

There is no escaping the fact that we are constantly being exposed to environmental pollutants. These poisons are all around us from when we get up until we sleep. Many people don’t realize just how harmful these pollutants can be and often underestimate their effects on human health. 
Below, we will discuss 8 effects of environmental pollution on human health.

1. Respiratory Problems

Air pollution is one of the most prevalent environmental dangers on human health, and it can induce various respiratory issues, including bronchitis, asthma, and even lung cancer.
This is due to air pollution being a combination of harmful gases and particles which, if inhaled, can lead to damage to our lungs. Long-term exposure has been linked with an increased chance of developing respiratory problems by studies.
Furthermore, those with weaker immune systems, such as the elderly and very young children, 
are highly susceptible to the negative effects of air pollution.

2. Cardiovascular Diseases

Air pollutants and other environmental factors, such as radiation and stress, have been linked to heart disease. Air pollution has increased the risk of heart attacks, strokes, and other cardiovascular issues. This is because air pollution may cause inflammation and hardening of the arteries, which can lead to these diseases.
In addition, exposure to water pollution can also lead to an increased risk of cardiovascular disease. This is because water pollution can contain harmful chemicals and toxins that can enter our bloodstream and damage our hearts and blood vessels.

3. Cancer

Cancer is another serious health problem that environmental pollutants can cause. Studies have shown that exposure to certain pollutants, such as asbestos, benzene, and radiation, can increase cancer risk.These pollutants can damage our cells and DNA, leading to cancerous cell development. In 
addition, children and the elderly are particularly vulnerable to the effects of these pollutants.

4. Birth Defects

Exposure to environmental pollutants can also lead to congenital disabilities. Studies have shown that pregnant women exposed to certain pollutants, such as mercury, lead, and pesticides, are more likely to give birth to babies with congenital disabilities.
These pollutants can damage the developing fetus and cause various health problems, such as 
developmental delays, learning disabilities, and physical abnormalities. In addition, exposure to 
air pollution can also lead to low birth weight and premature birth in human beings and animals.

5. Brain Damage

Environmental pollutants can also cause brain damage. Exposure to certain pollutants, such as lead and mercury, can damage the brain and cause various problems, such as learning disabilities, memory problems, and behavior problems in human beings and animals. These pollutants can cause brain damage because they can damage the cells and nerves in the brain. In addition, children and the elderly are particularly vulnerable to the effects of these pollutants.

6. Kidney Damage

Pollutants in the environment can also cause kidney damage. Pollution, such as lead and mercury, has been shown in studies to harm the kidneys and induce kidney disease. The reason why these pollutants can cause kidney damage is that they can accumulate in the kidneys and can affect the health of the tissues and cells or even cause damage to the tissues and cells. In addition, people with diabetes and hypertension are particularly vulnerable to the effects of these pollutants.

7. Liver Damage

Environmental pollutants not only put a strain on our liver, but they can also cause long-term damage. For example, lead and mercury exposure has been linked to developing liver disease. These pollutants accumulate in the liver and can damage the cells and tissues. In addition, people with liver diseases, such as hepatitis and cirrhosis, are particularly vulnerable to the effects of 
these pollutants.​ 

8. Reproductive Problems

Environmental pollutants aren’t just bad for the planet–they can also cause serious reproductive problems in humans. Various studies have revealed how different toxins, for example, mercury and lead, can harm the reproductive system. The damage caused by these pollutants may present as infertility, miscarriages, or congenital disabilities.
The reason why these pollutants can cause reproductive problems is that they can damage the eggs and sperm. By damaging the eggs and sperm, these pollutants can prevent fertilization or cause the embryo to be abnormal.


Environmental pollutants are a major problem that can cause various serious health problems. Therefore, it is important to be aware of the dangers of these pollutants and take steps to protect yourself and your family from them. Some ways you can do this include staying informed about the quality of the air and water in your area and avoiding exposure to polluted areas.
