Effects Of Soil Pollution On Human Health – Learn the insider secrets of what the best hedge funds are doing today to maximize returns.

Soil pollution is invisible to the human eye, but it affects the food we eat, the water we drink and the air we breathe. Contaminants enter the soil, then migrate into the air and water and enter our agri-food system, harming the environment and health.

Soil Pollution And Risk To Human Health

As part of the celebration of World Environment Day, the Food and Agriculture Organization (FAO) and the United Nations Environment Program jointly launched the United Nations 10-year restoration of ecosystems (2021-2030). The Report is about to begin.

Global environmental degradation, caused by increasing demands on agricultural, food and industrial systems as the world’s population continues to grow, is one of humanity’s greatest challenges.

Since ancient times, as a result of human activities, thousands of different synthetic chemical compounds and naturally occurring toxic elements have been released into the environment. These pollutants persist in the environment for hundreds of thousands of years and are distributed throughout the world.

Pollution is a global problem that knows no borders. Pollutants are found in the most remote parts of every continent and are easily transported from one country to another.

Planetary Limits To Soil Degradation

Soil is one of the main receptors of pollutants. Soil pollution is one of the main threats to soil health, but its effects go beyond the soil, and soil pollution has irreversible effects on the health of humans and ecosystems.

Contaminated soil is a source of pollutants in all parts of the environment, including water, air, food, and living things, including humans. As Planet Health and the One Health Initiative emphasize, ecosystem and human health are interconnected, but cannot be effectively addressed without addressing soil pollution.

Effects Of Soil Pollution On Human Health

Soil pollution damages ecosystems, causes serious economic losses and social inequalities and threatens the achievement of the 2030 Agenda for Sustainable Development.

How Does Water Pollution Affect Human Health?

The main sources of pollutants that cause soil pollution (in order of importance) are industrial activities, mining, waste disposal, agriculture, fossil fuel extraction and processing, and transportation. However, there is no real and comparable data on the actual emissions of each sector.

With the exception of agrochemicals, most pollutants released into the soil cannot be easily quantified and the results are uncertain. Industrial pollutants are released into the environment throughout their life cycle, from production to production, transport, use and disposal.

Since the beginning of the 20th century, the world’s annual production of industrial chemicals has doubled to about 2.3 billion tons, and is expected to increase by 85% by 2030. Thus, without rapid changes in production, soil and environmental pollution will increase. and a political commitment to practical sustainable management that fully respects consumption patterns and nature.

Despite decades of research, inventory and monitoring of contaminated soils in several countries, significant knowledge and uncertainties remain about the number and extent of affected areas, leading to the emergence of new contaminants. There is a larger gap in knowledge about the effects of particulate pollution on soil and other parts of the environment.

Urban Soil And Human Health: A Review

Organic and emerging pollutants such as pharmaceuticals and antimicrobials, resistant bacteria, industrial chemicals and plastic waste are of concern to society. In the current global pandemic situation due to COVID-19, waste is being generated rapidly and the pressure on the environment is increasing.

The large number of pollutants, their physico-chemical properties and various interactions with the soil (which determine the fate of the pollutant) make it difficult to estimate pollutant loads. Scientific knowledge about the fate of emerging pollutants is currently lacking. In many parts of the world, it is very difficult to establish global distribution patterns because there is no regular systematic analysis and monitoring in soil laboratories (the soils are more oriented towards agriculture).

Identifying and assessing the risk of contaminated sites is the most important step in managing soil contamination. If the area is contaminated to a level that harms organisms, information about the area should be collected and made public at the appropriate level of government, and appropriate remedial and risk reduction measures should be taken, especially if the area is used for food production or production. human consumption

Site identification also enables site ownership, which is the basis of the “polluter pays” principle. Although many countries have effective processes for identifying and assessing contaminated sites, many states still lack this basic step of determining who is responsible (the polluter).

The management and remediation of contaminated sites is necessary to protect human health and the environment. The regional chapters of the main report show successful approaches to managing contaminated sites in each region. The exchange of experience at the regional level can help a lot in solving the problem of soil pollution.

Clear lines of communication between scientific institutions, policy makers and society are needed to provide policy makers and other interested parties with timely and scientifically based information on the potential risks of pollutants.

Remediation of soil contamination is technically complex and expensive, costing tens of thousands to hundreds of millions of dollars annually. Remediation costs vary depending on the nature of the site, the type and concentration of pollutants, the parts of the environment affected (eg, surface water, groundwater, surface water) and measures to protect the population. Rehabilitation works, post-rehabilitation land use and selected technologies.

The production, use, transport and disposal of the most harmful soil pollutants are regulated by international agreements (Stockholm, Basel, Rotterdam and Minamata Conventions). In some areas, these global agreements are being extended through regional agreements, such as the Bamako Convention on the Import Ban into Africa and the Control of Transboundary Migration and Control of Hazardous Waste Management in Africa. States that are not parties to the Convention should strongly promote its entry into force.

Human Impact On The Nitrogen Cycle

As global pollution trends worsen, greater political, business and social commitment is needed to offset the use of toxic pollutants and increase investment in research, prevention and remediation.

Enhancing cooperation and collaboration is essential to ensure knowledge acquisition, sharing of best practices and adoption of clean and sustainable technologies.

Chemical products that act as environmental pollutants in the soil and pose a risk to human health and the environment are inorganic or organic compounds. Figure 2 shows a systematic classification of the most common pollutants in soil, according to their chemical properties. Intrinsic pollutants are not included in this figure because they are classified into different categories. Soil fate (Figure 3), including persistence, mobility, and effects on organisms elsewhere in the environment, is determined by contaminants and local soil properties. Determining the sources of trace elements in nature is important for understanding their pollution patterns and making remedial decisions.

Effects Of Soil Pollution On Human Health

Soil pollution has long-term effects on human health (Figure 4), and many variables determine the relationship between soil pollution and disease, including:

Pollutants in this group include elements or compounds of natural or anthropogenic origin in the bed. The main inorganic pollutants (trace elements, radionuclides, asbestos) are described below.

The term “trace elements” generally refers to ubiquitous elements present in the environment at very low levels and potentially harmful to living organisms. Trace elements include heavy metals (ie metals with high atomic mass), lead (Pb), cadmium (Cd), cobalt (Co), copper (Cu), chromium (Cr), mercury (Hg), and tin. Sn), nickel (Ni) and zinc (Zn). Metals that are considered trace elements include arsenic (As), antimony (Sb) and selenium (Se).

Micronutrients are persistent and do not break down through metabolic processes. Micronutrients exist in various forms, such as salts, oxides, sulfides, organic compounds, or dissolved ions in soil solutions. Partitioning of air, water and soil occurs through chemical processes, such as particle absorption or pH-dependent dissolution in water (Alloway, 2012).

Trace elements have a geogenic (natural) origin, as many rocks contain high levels of elements released into the environment by weathering or human activity. Many soils have a natural footprint
