Biogeochemistry

Biogeochemistry is a branch of natural science that studies the role of living organisms and their communities in geochemical processes and their impact on the environment. This branch of science examines how living organisms influence the formation and evolution of geochemical cycles, as well as how geochemical processes influence the development and functioning of living organisms.

Biogeochemistry is of great importance for understanding the global changes taking place on our planet. It helps scientists understand how interactions between living organisms and geochemical processes influence biodiversity, climate and ecosystems. In addition, biogeochemistry can be used to solve practical problems in medicine and healthcare, for example, in the field of regional pathology, when it is necessary to determine the causes of diseases and develop methods for their treatment.

One of the key concepts in biogeochemistry is the biogeochemical cycle of elements. It is the process by which living organisms extract elements from their environment, use them for their growth and development, and then return them back to the environment in the form of excrement or dead organisms. Biogeochemical cycles of elements play an important role in maintaining the balance of elements in ecosystems and preventing their excess or deficiency.

Another important concept in biogeochemistry is the geochemical environment. This is a set of chemical elements and their compounds that are found in the atmosphere, hydrosphere and lithosphere. The geochemical environment plays a key role in determining the availability of elements for living organisms and in creating the conditions for their growth and development.

In general, biogeochemistry is an important branch of natural science that helps to better understand the processes occurring in nature and develop methods for managing ecosystems. It has wide applications in medicine, agriculture, industry and other areas related to environmental protection and sustainable development.

Humans have biogeochemical significance. Over 20 chemical elements are determined in the human body, the most important of which is calcium. Rickets and osteoporosis, which arise from a lack of calcium, contribute to bone destruction. Chronic calcium deficiency in children leads to the development of rickets, decreased bone strength, and diseases of internal organs.

It takes about 840 million years for the body to obtain calcium from the soil.
