The Elemental Composition of a Human Body

The human body is a miraculous, well-oiled, and exceptionally complex machine. It requires a multitude of functioning parts to come together for a person to live a healthy life—and every biological detail in our bodies, from the mundane to the most magical, is driven by just 21 chemical elements.

Of the 118 elements on Earth, just 21 of them are found in the human body. Together, they make up the medley of divergent molecules that combine to form our DNA, cells, tissues, and organs.

Based on data presented by the International Commission on Radiological Protection (ICRP), in the above infographic, we have broken down a human body to its elemental composition and the percentages in which they exist.

These 21 elements can be categorized into three major blocks depending on the amount found in a human body, the main building block (4 elements), essential minerals (8 elements), and trace elements (9 elements).

The Elemental Four: Ingredients for Life

Four elements, namely, oxygen, carbon, hydrogen, and nitrogen, are considered the most essential elements found in our body.

Oxygen is the most abundant element in the human body, accounting for approximately 61% of a person’s mass. Given that around 60-70% of the body is water, it is no surprise that oxygen and hydrogen are two of the body’s most abundantly found chemical elements. Along with carbon and nitrogen, these elements combine for 96% of the body’s mass.

Here is a look at the composition of the four elements of life:

ElementWeight of Body Mass (kg)Percentage of Body Mass (%)
Oxygen43 kg61.4%
Carbon16 kg22.9%
Hydrogen7.0 kg10.0%
Nitrogen1.8 kg2.6%

Values are for an average human body weighing 70 kg.

Let’s take a look at how each of these four chemical elements contributes to the thriving functionality of our body:

Oxygen

Oxygen plays a critical role in the body’s metabolism, respiration, and cellular oxygenation. Oxygen is also found in every significant organic molecule in the body, including proteins, carbohydrates, fats, and nucleic acids. It is a substantial component of everything from our cells and blood to our cerebral and spinal fluid.

Carbon

Carbon is the most crucial structural element and the reason we are known as carbon-based life forms. It is the basic building block required to form proteins, carbohydrates, and fats. Breaking carbon bonds in carbohydrates and proteins is our primary energy source.

Hydrogen

Hydrogen, the most abundantly found chemical element in the universe, is present in all bodily fluids, allowing the toxins and waste to be transported and eliminated. With the help of hydrogen, joints in our body remain lubricated and able to perform their functions. Hydrogen is also said to have anti-inflammatory and antioxidant properties, helping improve muscle function.

Nitrogen

An essential component of amino acids used to build peptides and proteins is nitrogen. It is also an integral component of the nucleic acids DNA and RNA, the chemical backbone of our genetic information and genealogy.

Essential and Supplemental Minerals

Essential minerals are important for your body to stay healthy. Your body uses minerals for several processes, including keeping your bones, muscles, heart, and brain working properly. Minerals also control beneficial enzyme and hormone production.

Minerals like calcium are a significant component of our bones and are required for bone growth and development, along with muscle contractions. Phosphorus contributes to bone and tooth strength and is vital to metabolizing energy.

Here is a look at the elemental composition of essential minerals:

ElementWeight of Body Mass (g)Percentage of Body Mass (%)
Calcium1000 g1.43%
Phosphorus780 g 1.11%
Potassium140 g0.20%
Sulphur140 g0.20%
Chlorine100 g0.14%
Sodium95 g0.14%
Magnesium19 g0.03%
Iron4.2 g0.01%

Values are for an average human body weighing 70 kg.

Other macro-minerals like magnesium, potassium, iron, and sodium are essential for cell-to-cell communications, like electric transmissions that generate nerve impulses or heart rhythms, and are necessary for maintaining thyroid and bone health.

Excessive deficiency of any of these minerals can cause various disorders in your body. Most humans receive these minerals as a part of their daily diet, including vegetables, meat, legumes, and fruits. In case of deficiencies, though, these minerals are also prescribed as supplements.

Biological Composition of Trace Elements

Trace elements or trace metals are small amounts of minerals found in living tissues. Some of them are known to be nutritionally essential, while others may be considered to be nonessential. They are usually in minimal quantities in our body and make up only 1% of our mass.

Paramount among these are trace elements such as zinc, copper, manganese, and fluorine. Zinc works as a first responder against infections and thereby improves infection resistance, while balancing the immune response.

Here is the distribution of trace elements in our body:

ElementWeight of Body Mass (mg)Percentage of Body Mass (%)
Fluorine2600 mg0.00371%
Zinc2300 mg0.00328%
Copper72 mg0.00010%
Iodine13 mg0.00002%
Manganese12 mg0.00002%
Molybdenum9.5 mg0.00001%
Selenium8 mg0.00001%
Chromium6.6 mg0.00001%
Cobalt1.5 mg0.000002%

Values are for an average human body weighing 70 kg.

Even though only it’s found in trace quantities, copper is instrumental in forming red blood cells and keeping nerve cells healthy. It also helps form collagen, a crucial part of bones and connective tissue.

Even with constant research and studies performed to thoroughly understand these trace elements’ uses and benefits, scientists and researchers are constantly making new discoveries.

For example, recent research shows that some of these trace elements could be used to cure and fight chronic and debilitating diseases ranging from ischemia to cancer, cardiovascular disease, and hypertension.

What is the FIFA World Cup Trophy Made Of?

This infographic explores the history and composition of the FIFA World Cup trophy ahead of the 22nd edition of the competition.

What is the FIFA World Cup Trophy Made Of?

Soccer is one of the world’s most popular sports with approximately 3.5 billion fans globally.

It was in Uruguay, in 1930, that the very first FIFA World Cup was held. It has occurred once every four years since then (except in 1942 and 1946 due to World War II).

This year, 92 years after its start, the 22nd FIFA World Cup tournament is scheduled to take place in Qatar. The highly anticipated event involves 32 national teams that will compete to win one of the most prestigious titles and a historic trophy.

So, what is the coveted FIFA World Cup trophy made up of?

The History and Composition of FIFA World Cup Trophies

Since its debut in the first FIFA World Cup tournament, in 1930, there have been two iterations of the World Cup trophy. Both trophies were made with a combination of metals and rare stones.

Until 1970, the Jules Rimet Trophy, designed by the French sculptor Abel Lafleur, glorified the winning team. A redesigned version of the trophy by Silvio Gazzaniga replaced the original in the 1974 FIFA World Cup tournament.

The Jules Rimet Trophy

Commonly called the Coupe du Monde (French for World Cup), the Jules Rimet trophy was officially renamed in 1946, honoring the then FIFA president Jules Rimet on his 25th Anniversary in office.

The trophy had a height of 35cm and weighed 3.8kg. It was made of gold-plated sterling silver and featured Nike, the Greek Goddess of Victory, holding an octagonal cup. The base of the trophy was made from a semi-precious stone called lapis lazuli. Golden plates were attached to each side of the base and they held the names of the winning teams from 1930 to 1970.

Since the beginning, it was agreed that the first team to win the World Cup three times would get to permanently keep the trophy. In 1970, Brazil marked its third victory by beating Italy in the finals and took the Jules Rimet trophy home.

However, in 1983, the trophy that even survived World War 2 was stolen from the Brazilian Football Confederation (CBF) headquarters in Rio de Janeiro and was never found. The only original piece of the Jules Rimet trophy in existence is the base that was replaced in 1954 to accommodate more winning-team names.

The FIFA World Cup Trophy

After handing over Abel Lafleur’s original trophy to Brazil in 1970, FIFA held a design competition in search of a new World Cup trophy. The association received 53 submissions from seven countries and Silvio Gazzaniga’s design of two human figures holding the Earth in their hands won the competition.

This new trophy is 36.5cm tall and weighs 6.17kg. It is made from 5kg of 18-karat gold and two layers of malachite. The base of the trophy is 13cm in diameter and the names of all winning teams since 1974 along with the years are engraved on it. This current iteration of the World Cup trophy can accommodate the names of 17 winning countries and years.

Unlike the Jules Rimet trophy, the current iteration of the trophy will not be handed over to a team definitively. It permanently belongs to the International Federation of Association Football (FIFA) and is secured at its Zurich headquarters.

However, a gold-plated bronze replica of the cup referred to as the World Cup Winners’ Trophy is given to every winning team.

Battle Royal: The 2022 FIFA World Cup

The 2022 FIFA World Cup tournament is long awaited by billions of passionate soccer fans.

It could be the final opportunity for two of the world’s best players—Cristiano Ronaldo, and Lionel Messi—to lift the World Cup trophy as they supposedly plan to retire from international games before the next World Cup.

This year, will your favorite national team be able to pose for a victory picture holding the golden trophy in their hands?

The Top Cotton Producers

Cotton is present in our everyday life, from clothes to coffee strainers, and more recently in masks to control the spread of COVID-19.

As the most-used natural fiber, cotton has become the most important non-food agricultural product. Currently, approximately half of all textiles require cotton fibers.

The above infographic lists the world’s top cotton producers, using data from the United States Department of Agriculture.

Fancy Fabric

Originating from the Arabic word “quton,” meaning fancy fabric, cotton is a staple fiber made up of short fibers twisted together to form yarn.

The earliest production of cotton was around 5,000 B.C. in India, and today, around 25 million tons of cotton are produced each year.

Currently, five countries make up around 75% of global cotton production, with China being the world’s biggest producer. The country is responsible for over 23% of global production, with approximately 89 million cotton farmers and part-time workers. Cotton’s importance cannot be understated, as it is the primary input for the Chinese textile industry along with many other nations’ textile industries.

Top Cotton Producers2020/2021 (metric tons)2021/2022 (metric tons)
🇨🇳 China 6,445,0005,835,000
🇮🇳 India6,009,0005,334,000

🌐 Other 4,059,0004,282,000
Total24,271,00025,155,000

The United States is the leading global exporter of cotton, exporting three-fourths of its crop with China as the top buyer.

Despite its importance for the global economy, cotton production faces significant sustainability challenges.

The Controversy Over Cotton

Cotton is one of the largest users of water among all agricultural commodities, and production often involves applying pesticides that threaten soil and water quality.

Along with this, production often involves forced and child labor. According to the European Commission, child labor in the cotton supply chain is most common in Africa and Asia, where it comes from small-holder farmers.

In 2020, U.S. apparel maker Patagonia stopped sourcing cotton from the autonomous territory of Xinjiang because of reports about forced labor and other human rights abuses against Uighurs and other ethnic minorities.

L Brands, the parent company of Victoria’s Secret, has also committed to eliminating Chinese cotton from its supply chain. Whether these changes in supply chains impact China’s cotton production and its practices, cotton remains essential to materials found across our daily lives.
