Based on the analysis of statistical yearbooks "state of contamination of soils and objects of the natural environment of the Russian Federation with pesticides and toxicants of industrial origin", analysis of the incidence of workers and the population from exposure to residual pesticides and heavy metals, the need to assess soil contamination for organic farming purposes in accordance with the requirements of article 9 of the Federal law of 03.08.2018 No. 280-FZ "on organic products and amendments to certain legislative acts of the Russian Federation"is justified. For evaluation, a digital technology is proposed in the management of environmental safety and labor protection in agriculture, developed by scientists of the ITOSH-branch of the FGBNU FNAC VIM. It is proposed to solve the problems of detoxification of soils contaminated with heavy metals and residual pesticides identified during the assessment using the available domestic and foreign experience by various methods: physical, physical-chemical, and biological.

Great Harm

Heavy metals contaminated sediment has become a worldwide environmental issue due to its great harm to human and aquatic organisms. Thus, economical, effective, and environmentally-friendly remediation technologies are urgently needed. Among which, combined remediation technologies have attracted widespread attention for their unique advantages. This paper introduces combined remediation technologies based on physical-, chemical-, and bio-remediation of heavy metal polluted sediments. Firstly, the research progress in physical-chemical, bio-chemical, and inter-organismal (including plants, animals, microorganisms) remediation of heavy metal polluted sediments are summarized. Additionally, the paper analyzes the problems of the process of combined remediation of heavy metals in river sediments and outlooks the future development trends of remediation technologies. Overall, this review provides useful technology references for the control and treatment of heavy metal pollution in river sediments.

Orthodontic Forces

Orthodontic forces deform the extracellular matrix and activate cells of the paradental tissues, facilitating tooth movement. Discoveries in mechanobiology have illuminated sequential cellular and molecular events, such as signal generation and transduction, cytoskeletal re-organization, gene expression, differentiation, proliferation, synthesis and secretion of specific products, and apoptosis. Orthodontists work in a unique biological environment, wherein applied forces engender remodeling of both mineralized and non-mineralized paradental tissues, including the associated blood vessels and neural elements. This review aims at identifying events that affect the sequence, timing, and significance of factors that determine the nature of the biological response of each paradental tissue to orthodontic force. The results of this literature review emphasize the fact that mechanoresponses and inflammation are both essential for achieving tooth movement clinically. If both are working in concert, orthodontists might be able to accelerate or decelerate tooth movement by adding adjuvant methods, whether physical, chemical, or surgical.
