Improbable: The Contamination Free Production Process Of The

In recent years, soil contamination with pesticides has become a crucial news issue with serious short- and long-term effects on human health and its environment. Pesticides play a significant role in the success of Free farming and food production. These compounds have potential for toxicity and adverse effects on human health and ecological soil systems. Pentachlorophenol PCP is one of the most recalcitrant chemicals polluting the environment for its stable aromatic ring system and chloride content.

Nowadays, many sites are contaminated with this substance. In these areas, concentrations may stay high for a long time because of slow degradation in the soil due to the negative effects that PCP has on soil microbial populations.

In the present chapter, we present an overview of the effect of PCP pesticide contamination on soil microbial populations density and diversityenzymatic activity and physicochemical parameters. Additionally, the bioremediation process will be detailed. Soil is an active, dynamic, and nonreplaceable reserve, and its situations impact its construction, environmental efficacy, and total stability [ 12 ].

The charge of soil reposes on in portion on its ordinary structure and on the variations affected by human use and administration [ 3 ]. Soil, as the main interface with other environmental compartments, plays an important role in the fate of organic pollutants.

The ground therefore occupies a position central in regulating the fate of pesticides in the environment, and it will have a dual role of storage and purification [ 4 ]. Pollutants come into contact with soil primarily through deliberate application, dispersion, and atmospheric deposition. The soil therefore represents a storage reservoir for these substances.

These compounds can also be lost from the soil or remain at high concentrations. Consequently, the fate and behavior of organic contaminants in soils have been the subject of intense research, with particular interest in the bioavailability of these contaminants [ 5 ]. The greatest difficulties in studying and estimating the retention and degradation of pollutants in soil are the diversity of chemical structures and reactivity of these compounds on the one hand and the high level read more diversity of soils in terms of structure and composition, soil, and climatic conditions, especially soil temperature and humidity on the other [ 6 ].

Soil pollutants are very diverse, and they are also often harmful and toxic to all living forms and more specifically humans Roger and Jacq, The occurrence of pollution most often results from industrial accidents, deposits, or the transport of dangerous materials [ 7 ]. Like pesticides, chlorinated solvents, nitrogen, and certain trace elements The Contamination Free Production Process Of The as copper, mercury, or silver, pollutants can both be naturally present in the soil or be the result of human activities.

This generalized use of PCP has led to the contamination of water and soil systems, with PCP currently considered to be a product of priority for decontamination studies [ 8 ]. These compounds are, in fact, the source of many concerns for companies operating in the wood preservation sector.

Chlorine compounds are harmful, and they are found in the effluents of many industries, such as the chemical and petrochemical industries, those of Prodhction and coking plants, pesticides, textiles, paper, and even in the pharmaceutical industry and many others [ 9 ]. This is why these chlorinated compounds appear as the most frequently encountered pollutants in various natural environments such as forests, rivers, marine waters, industrial discharges, urban effluents and even in the groundwater. The soil has a marked self-purification capacity.]
