Even though there are so many benefits that modern industrialization has brought on our doorstep, we cannot help but note how factories and manufacturing units generate so much pollution, which ultimately contributes to global warming.
The existing methods often do not have proper protocols in place and the workforce can operate negligently without the same. Pollution, well, it certainly has an ominous reputation, and for a good reason.
It is a long-term problem that can impact our entire planet. But do you know that chemical pollution is a considerable component of the danger involved? You see chemicals are everywhere - in the air we breathe, the food we eat, and the products we use.
Most chemicals are human-made and used in various industries - from agriculture and healthcare to automotive to supply chain management. But to use it properly, we need a stable ecosystem; sometimes, that is not possible - resulting in spill or leakage - or pollution!
Moreover, the chemical industry, comprising the companies that produce industrial chemicals, has a massive responsibility. Central to the modern world economy, it converts raw materials such as natural gas, oil, metals, water, and minerals into more than 70,000 different products.
It is also the largest industrial user of oil and gas with the third-largest carbon footprint. Not so surprisingly, it produces pollution which has adverse long-term effects. However, identifying pollution is only half the battle. You need to have proper resources and solutions to have it controlled.
And that is where using IoT can make a huge difference. In this article, we will study how the Internet of Things (IoT) can be used for pollution control in chemical industries. But first, let us get the fundamentals out of the way:
Statistics of pollution generated by the chemical industry
While the entire world works on solutions, there is surprisingly little focus on the chemical industry that accounts for 7% of global greenhouse gas emissions. Let us look at a few other numbers that establish the fact that chemical industries are harmful and they produce a lot of pollution:
- Despite the strict regulations by the statutory authorities worldwide, there has been no significant improvement in the global pollution index.
- Following the TRI National Analysis, 3.5+ billion pounds of hazardous chemicals are released into the environment every year. As a result, it has led to facility explosions, and people in nearby areas have reported suffering from severe illnesses such as cancer and respiratory ailments. The pollution has ultimately led to an ecosystem imbalance and degraded the quality of human lives.
- According to the latest report by The Lancet, global pollution is responsible for causing over nine million deaths annually. Out of which, 7% of environmental hazards occur due to chemical industry operations.
What is chemical pollution?: An introduction
Chemical pollution is the contamination of the environment by chemicals that do not occur naturally. Precisely, it is directly proportional to human activities involving using toxic chemicals for various purposes.
The chemical pollutants are majorly industrial; a growing danger to the entire habitat and a more significant threat to humanity. Today, chemicals are ubiquitous, and we cannot escape from their grave consequences because they are not only processed for industrial usage but also in households, medicines, food, and many other everyday products.
This results in chemical intoxication of our surroundings such as air, water, and soil. It induces acute, subacute, and chronic illnesses, or even death. Undoubtedly, controlling chemical usage is a challenge with the ever-increasing consumer demands.
From cosmetics, drugs and nutrients to cleaning utilities and gardening products, chemical compounds are used in various products, and the effect of many of them on the environment is largely unknown.
In addition, it is vital to know the type of chemical pollution you are dealing with. Considering our ecosystem, this type of pollution extensively contributes to air, water, and soil pollution. For instance, chemical soil pollution only impacts the direct site but can invade the groundwater.
- The greenhouse gas emissions for electricity, transportation, agriculture, industrial, residential and commercial end-uses contaminate the air we breathe.
- The plastic and chemical releases in the water, sea, and ocean lead to dead zones and impact marine biodiversity.
- Agricultural, industrial, mining, and waste disposal adversely affect soil quality as they kill the microorganisms that support soil fertility.
Chemical air pollution impacts the ozone layer and can cause global changes in temperature and climate. Given the spread of this type of pollution, it is evident that more people are affected by it on a worldwide scale.
And since some of the most harmful chemicals are “forever chemicals,” these can get into our bodies and environment and not break down, disrupting our nervous system, immunity, and hormones.
For example, chemical water pollution can result in illness, poor reproductive success, and human fatality. It can cause sickness and long-term health problems in humans, and bioaccumulate in animals.
How is chemical pollution caused?
The gaseous and smoke pollutants, effluents, waste materials disposal, acid mine drainage, and toxic chemical residues and by-products cause chemical pollution.
It results from producing, processing, manufacturing, handling, storing, and dumping chemicals in natural environments. These activities occur in industrial places such as:
- Steel mills
- Heating plants
- Power stations
- Oil refineries
- Coal power plants
- Transportation firms
- Agriculture companies
- Sewage treatment plants
- Mining and smelting plants
- Textile manufacturing units
The chemical compounds produced by them are the primary chemical pollutants. Some are ultra harmful and do not break down - remaining persistent for thousands of years. It means they endure for a long time and disrupt hormones when they contaminate a human body or environment. As per chemical structure, these chemical compounds comprise of the following:
1. Organic chemical pollutants
They are toxic synthetic biodegradable chemical compounds called Persistent Organic Pollutants (POPs). Chemical pollution examples include pesticides, insecticides, herbicides, detergents, plastics, phenols, alcohols, chlorinated solvents, polyaromatic hydrocarbons (PAHs), synthetic clingers, and crude oil and petroleum refined products.
2. Inorganic chemical pollutants
They usually originate from radiant energy, noise, heat, or light. And contain poisonous non-biodegradable chemical compounds. Examples include heavy metals, salts, sulfides, acids and bases, ammonia and nitrogen oxides, perchlorate, and chemical fertilizers.
