In this modern era, agricultural communities
use pesticides to kill, prevent, and control insects and other harmful pests that
influence plant and crop growth. Regardless of their efficiency, insect killers
comprise toxic chemicals that have long-term impacts on the human nervous
system as well as their senses. First, in the 1930s these chemicals have been used
to keep safe crops by the United States and then widely spread after Second
World War. Afterwards, various agricultural communities started to utilize them
because of how much they impacted crop production. Today,
around two million
tonnes of insect killers are used annually in the entire world and China is utilizing a huge number of pesticides,
followed by developed countries like Argentina and the USA. As specified in a report by
the World Health Organization (WHO) globally
over 1,000 various types of chemicals are utilized to protect crops among them the well popular forms are herbicides, fungicides,
bactericides and pesticides.
Who is Vulnerable?
Those
communities that are directly susceptible to pesticides are at risk. This comprises
pesticide-applying agricultural people and anyone else in the instant vicinity
during and abruptly after pesticides are used. Similarly, when exposed to the general population the
food and water resources exist considerably lower levels of pesticide remains than
the area where pesticides are used.
In
1990, the world used £3.72 billion in pesticides. This level has been
projected to reach £5.86 billion by 2020. The United
Nations Environment Program's report
proposes that the use of different pesticides will increase and the population
of the world is expected to reach 10 billion by 2050, which will necessitate a
60% increase in food making,
the production of meat almost 70%, aquaculture
production by 90% and dairy food products by 55%. The researchers have
confidence in that farmers will require to utilize further pesticides to meet
this requirement. A study of European farming practices realized that completely removing pesticides could affect crop production declines of 78% in fruits,
54% in vegetables, and 32% in grain production.
But
human dependency on pesticides influences the environment as well. According to a study on
pesticides, these chemicals may be blamable for the deficiency in sense of
smell in bees and salmon fish, they contaminate water resources and put pressure
on water ecosystems.
Another process is called bioaccumulation in which pesticides enter the food chain. It occurs when an element starts to increase in our body as we fail to break it down. For this reason that many synthetic pesticides are not possible to break down by the human body and animals and they can store in the body in the form of fat. This can have unpleasant outcomes on human health. Despite global protocols on pesticide utilization, one study observed that there are nearly 385 million incidents of unintentional, acute pesticide poisoning (UAPP) exist among agricultural workers each year.

When pesticides are sprayed they produce fumes that convert into air toxins. In the USA, between 37 to 54% of pesticides are associated with illnesses among agricultural people and are characterized by sprays on various crops. Significant symptoms such as headache, skin nausea and irritation can be included. Also, acute health effects range from seizures to respiratory difficulties and the period of exposure to the type of pesticide applied, all affect the human senses and nervous system.
One
of the oldest cases happened in the 1960s in the Saku agricultural area of
Japan. Inhabitants of the region had a high rate of visual deficiency after contact
with organophosphates. Effects of organophosphates include blurred vision, eye
movement complaints, myopia and astigmatism. A study on residents in the region
acquired that farmers' wives who were influenced by pollution carried inside or
sprayed from close fields also underwent vision loss.
Hongli
Chen, a professor of epidemiology and biostatistics at Michigan State
University describes that when pesticide users get pesticide residue on their
skin or clothing people nearby inhale these residues through skin
absorption, inhalation, etc. This is due to a lack of personal protective
equipment or defective equipment. He reveals that when these pesticides enter
the body through inhalation then they disturb our nervous function. Moreover,
numerous types of research also illustrate a linkage between pesticide usage and
neurodegenerative diseases and cells in the human’s central nervous system die
and stop working.
A
study available in the journal of Environmental Toxicology states that children
are more likely at risk because of more consumption of liquids and food
according to per body pound weight than adults. In the Bordeaux area of France,
twenty-three primary school students have been affected with headaches, nausea
and skin problems after spraying fungicides in a vineyard in 2014. Then two
French conservational institutions filed a private court case, and the two
vineyards were charged €30,000.
Similarly,
in India, farmers use various pesticides in their fields for crop protection but
on another side, for many decades public health problems have been shown
especially among children. An investigative report that the effects of the
pesticide Alkaline Phosphatase (ALP) on many children in the northern part of
India reveals that 14 out of 30 children admitted to hospital for severe care have
not survived due to the consequences of the pesticide harm.
Moreover,
having thin skin ageing people are also mainly exposed due to insecticides
fumes, which augments the perils of poisoning by skin interaction, while the
functioning of their organs weakens and the kidneys and liver can take much
time to get rid of toxins which cause them riskier to store pesticides and also
make them physical damages and weakness of nerves system.
How to Control Harmful Effects?
According
to data provided by WHO and FAO, governments and intergovernmental institutions
will determine food criteria and control residue limits as much as possible for
pesticides in several food items. Even though consumers have inadequate monitoring
of the quantity and regularity of pesticides used in food, they can just reduce
the harmful effects by washing food and sanitizing their skin. This involves different
processes such as boiling, frying, cooking and blanching. Among these methods
washing and boiling is the most useful and easy method for the removal of
pesticide remains.
In
2001 Stockholm Convention on Persistent Organic Pollutants which entered into
force in 2004, was ratified by 152 nations to protect human health and the
environment. Some substances which include pesticides like Aldrin and DDT were
chosen and banned in light of their poisonousness, and the ability for
bioaccumulation in creatures and biological systems.
By
2030, it is committed by the European Commission to half the use of pesticides and
their risk as a role of the EU's plan for more sustainable food practices. Still,
a few agricultural communities believe that this target is inadequate. A movement
called "Save the Bees and Farmers"
has begun by agricultural campaigners who are involved in the agriculture
sector. This campaign urges the reduction of pesticides equal to 80% by 2030
and fully removed by 2035.
