What are the Negative Effects of Pesticidess

Negative Effects of Pesticides are more on humans and the atmosphere. The word pesticide covers insecticides, fungicides, herbicides, rodenticides, molluscicides, and nematicides.

A pesticide controls plant growth and others. Insecticides fight a number of diseases on plants. But, they were not in use in most of the countries after the 1960s ,due to their negative effects .

Preferably, the pesticides aim at the targeted pests. But not to non-target species, including humans. 

The more we use these chemicals, the more they cause negative effects and also problems with human and other life forms.

The use of pesticides in forests, in domestic and, of course, in agriculture, has more benefits.

The chemicals present in the pesticides show immediate results.The results of destroying the feeding of caterpillars on the plant, for example,it provides the primary benefit of increased production and improved efficiency of a plant.

The Negative Effects of pesticides on our health

Impacts of pesticides on our health

Pesticides contain dangerous chemicals, and also they can clearly do more damage to humans than just the pests they are being targeted at.

They are harmful, and pesticide exposure can have a number of effects on health. They cause a variety of serious diseases ranging from respiratory issues to cancer.



Pesticide exposure can occur in many different ways. In agriculture, farmers and farm workers use pesticides to treat pests on crops, plants, and grain stores.

In villages, the people who live next to farmlands are subject to pesticides.  Professional and domestic pest control contact may also take place through the treatment of wood with preservatives.

We get contaminants in our towns and cities through our gardens and playgrounds. A lot of people buy pesticides for home and garden use. And at last, remains of pesticides found on and in our food lead to more risks too.

Severe toxicity

Acute toxicity

Pesticides become actually highly harmful. It ensures that after a single episode of absorption,or inhalation, they can have harmful results. The signs are visible and may appear within 48 hours after contact.

They may present themselves as:

  • Eye and skin irritation
  • Nausea, vomiting, diarrhea
  • Headache
  • Lossof consciousness
  • Extreme weakness, seizures and/or death
  • Respiratory tract irritation
  • Sore throat and/or cough
  • Allergic reactions

Chronic toxicity

Chronic toxicity

One of the negative effects of pesticides is to cause harmful effects over a prolonged period or usually after repeated or continuous low-level exposure.

Low doses do not always cause immediate symptoms but they can cause very serious diseases over time.

Long-term exposure to pesticides develop Parkinson’s disease in people; asthma, anxiety and depression, lack of attention  are the other health disorders; and cancer including leukemia and lymphoma other than Hodgkin’s are serious diseases.

Endocrine disruptors

Endocrine disruptors

Endocrine disruptor applies to hormone-damaging compounds and hormone balance. Hormones are the body’s chemical messengers. They regulate growth and reproductive functions.

Rather low concentrations of chemicals can cause bad results.

The disorders and diseases are as follows:

  • Neurological disorders
  • Disorders in brain development
  • Parkinson’s disease
  • Hyper and hypothyroidism
  • Thyroid tumors.
  • Early puberty
  • The appearance of cysts in the ovaries 
  • Breast cancer
  • Pregnancy complications
  • Early abortions
  • Decreased fertility
  • Diabetes
  • Obesity
  • Reduced semen quality 
  • Genital malformations
  • Prostate cancer

Carcinogenic substances

Harmful effects of chemical pesticides

There is proof that carcinogen can cause cancer . There are many various types of cancer, but they all depend on the production of abnormal cells.

They start growing without control and spreading into surrounding tissues. Single exposure rarely cause cancer but long- term exposure can lead to cancer. Its either through absorption or through the eyes, skin or lungs.

Combined effects

The most dangerous issues related to pesticide exposure could be severe. When you use more of chemicals every day and  no one knows what effect this mixture of chemicals has on you. 

Not only are the effects , but there is also no attempt to solve the issue under present pesticide regulation. Since our system only studies the safety of individual chemicals.

Harmful effects of chemical pesticides

Repellents based on pesticides and lawn treatments become things of the past, as safer alternative products find a place among people. These new formulae are as good as their chemicals but without the negative side effects of pesticides.

Do you ever wonder what impact chemical pesticides have on our lives? They can do more damage than you think, with many possible harmful effects on the environment, our health and even within our home.

Environmental effects

Environmental effects

Chemical pesticides will pollute the environment. Although their  results are often short-lived.The tests have shown that the dangerous pollutants will stay alive long over in the soil, and in our waterways.

For nearly 100 years, people have used the chemicals in fields around the world. It creates a buildup of  pollutants in our environment with every application.

Unfortunately, when pesticides contact the surface, they travel by air, soil or water. This is one specific form that chemicals cause huge damage.

The Agricultural MU Handbook, Pesticides, and the Environment state that “too much activity within the soil will lead to reduced pest control, water and groundwater pollution, and damage to non-target species, including humans.”

In recent years, organizations such as the Organic Material Review Institute (OMRI) have taken steps to develop standards for these alternative products.

The private charity group is responsible for deciding whether a substance can last for long time, such as a repellent. Unlike chemical pesticides, each approved organic product has to pass a set of rigorous standards.

The standards for these certified organic goods were put in place to reduce adverse effects on humans, animals, and the environment.

Organic products are less harmful in composition and thus minimize or even remove extra damage. Capsaicin can help eliminate potentially harmful chemical pesticides from the environment,

And eventually from the products we eat, by promoting the use of plant-based synthetic repellents such as putrescent eggs.

The Negative Effects on soil and crops

Effects on soil and crops

As farmers worldwide depend on chemical pesticides, as a result, there will be a huge change in soil . If soil quality is damaged, the nutritional value of the food is also reduced.

“The U.S. government estimates that the mineral levels in fruit and vegetables dropped by up to 76 percent between 1940 and 1991,” says Cleeton. This change is directly linked to the existing pesticide exposure.

Not only do chemical pesticides reduce our food’s nutritional value but they also contaminate it. Researches have constantly found the remains of pesticides in foods.

It includes apples, baby food, bread, cereal bars, fresh salmon, lemons, potatoes, and strawberries. While pesticides are designed to kill living organisms, and certainly aren’t intended to enter our bodies.

Organic pesticides allow us to start with the soil. Decreasing the chemical contamination on soil creates a “return to nature”. Overall, they bring back vitamins and minerals, helpful organisms, and producing clean products.

Health effects

Health effects

Pesticides result in more illnesses. The Pesticides Literature Review, which is based on studies performed by a multi-university research team in Toronto, concludes that “people should reduce their exposure to pesticides due to serious diseases. The results of this study found constant proof of serious health risks such as cancer, diseases of the nervous system and reproductive problems in people due to the exposure of pesticides”.

Similar research has linked pesticide exposure to increased neurological disorders, asthma and much more. Progress towards organic repellents is a logical step which possibly help to reduce the chances of developing the disease.

Traces of chemicals were found in the bloodstreams of certain types of cancer sufferers. Having more Vitamins and Minerals defends you from continuous illness, James Cleeton claims that “women with breast cancer are five to nine times more likely to have impurities of pesticides in their blood than those who do not. 

2,4D and Atrazine are endocrine-damaging chemicals and they also cause breast and prostate cancers too.

Why don’t you prefer to organic repellents when you read fearsome statistics like these? You too, without using potentially harmful pesticides, can live with a beautiful, problem-free lawn and garden.

Indoor pollution

Indoor pollution

Did you know that you are always exposed to chemical pesticides while you are inside your home? You, your children or your pets can easily track pollutants indoors and from there, they can be absorbed into your body through your skin or lungs.

It won’t be good,if you think that you might be breathing in the very chemicals used to grow grass or kill pests while sitting at the dinner table or sleeping in bed.

William Baue , who works with the Children’s Health Environmental says, “While many pesticides quickly die when exposed to outdoor light and heat, sometimes they can continue to exist even for years, found in carpet fibers, furniture, and stuffed toys in an indoor environment.”

The U.S. Environmental Protection Agency (EPA) has found that indoor pollutant levels can be two to five times that of outdoor pollutants. However, the EPA lists indoor air emissions among the top four environmental health risks in the US.

Invisible particles and  gasses can gather but go  hidden in your home until the effects are noticeable. If you go with organic, that can help hugely reduce these contaminants. click here for types of pest.
