The existence of animal kingdom and plant world is based on soil. Contamination of the soil is a direct cause of contamination of the crops. Sulfates, nitrates, heavy metals and other unnatural products pollute the ground. Microorganisms like bacteria, viruses, and protozoa, can cause serious diseases like cholera. Ex: Organic wastes in animal dung may be used to prepare compost manure instead of throwing them wastefully and polluting the soil. As for agricultural practices, farmers should switch to natural fertilizers or treated manure.
However, our waste products are full of chemicals that are not originally found in nature and lead to soil pollution. While on the roads it is due to the unclean road over run by vehicles. Bioactive chemicals are also called Creeping Deaths. The most common way to determine if an area is polluted is to look at the stars, if you can see them your area is not so polluted. And so, they are laden with chemicals that are not found in nature. It is envisaged that the output of the project will be a short document providing high level guidance on health risk assessment with reference to existing published guidance and methodologies that have been identified as being particularly relevant and helpful. Soils that have been spoiled due to excessive use of chemicals and pesticides become barren.
Soil Pollution Effects The direct effects of soil pollution negatively influence the whole social and natural environment. Acid rain harms forests, species that live in water bodies, and degrades outdoor statues, monuments, and buildings. It is as simple as that. Industrial Toxins Close proximity to unregulated or even maintained industrial sites can introduce a myriad of contaminants to the soil, many of which won't break down quickly. Humans and animals eat the plants and ingest the dangerous contaminants. For the farms to become clean once again, levels of water, soil and have to be kept in check.
The causes behind soil pollution are many and growing. It is caused by emissions from manufacturing industries and power plants, vehicular emissions, smoking, natural events such as volcanic eruptions and wildfire, and burning of waste materials such as wood, rubber and plastics. Pollution can be defined as the introduction of contaminants to the natural environment, where the environment is affected negatively by the actions of humans. So, the more the toxic contaminants in the soil, the higher the level of toxic particles and foul gasses emitted into the atmosphere. This C-14 participates in Carbon metabolism of plants which is then into animals and human beings. When these changes occur, beneficial soil bacteria, microorganisms, nutrients, and the soil chemical process begin to deteriorate to an extent where they diminish the fertility of the soil. It can also destroy soil, and cause water and air pollution.
As a result, heavy metals are mixed in soil, turning it toxic. In a study conducted in Uttarakhand in January 2011, it has come to the light that the consumption of urea has increased by two and a half times in a year. Continuous deforestation Trees absorb carbon dioxide from the air; provide oxygen for humans and other organisms. The soil pollution can even lead to widespread famines if the plants are unable to grow in it. The soil pollution causes large tracts of land to become hazardous to health. However, it is definitely very important to us.
Plastic pollution: This is not a type but it deserves to be said one. Soil pollution differs slightly from land pollution because while they are affected in some of the same ways by the same contaminates, soil pollution focuses solely on the soil. Polluted soil can harm humans by making contact with the soil or consuming vegetation produce from contaminated soils. Urban wastes : Urban wastes that result in residential areas cause contamination of the soil at places where the wastes are not properly disposed. Polluted soil is also contaminating drinking water in the rivers and other sources of water through rain water. Bio-pesticides should be used instead of chemical pesticides. Such contaminants include metals, inorganic ions and salts e.
Many of these sites are abandoned or improperly-managed industrial zones. Human activities that pollute the soil range from agricultural practices that infest the crops with pesticide chemicals to urban or industrial wastes or radioactive emissions that contaminate the soil with various toxic substances. It harms the existence of microorganisms thriving on the soil. Pesticides, herbicides, insecticides, increase the salinity of the soil, making it imperfect for crop bearing and adversely affecting the microorganisms that help the soil and plants function. In fact, many pollutants that are more common in water or air pollution, can also cause soil pollution.
The consequences of humans ingesting such pollutants can include lead poisoning, deteriorating health, allergies and reduced immune system strength. Fertility of the land is severely affected due to the inclusion of toxic elements in the soil due to chemical fertilizers, pesticides, and industrial effluents. The harmful chemicals and heavy metals in the soil decrease soil microbial and chemical activity. Plants absorb many of these pesticides and when they decompose, they cause soil pollution since they become a part of the land. Chemical compost used in agricultural work, litter and dirt also badly pollute the soil.
