“…To remedy these sites, different proposals have been carried out, some have managed to re-establish the vocation of use, despite this, and there still problems after restoration such as toxicity and water repellency (Fawzy, 2008;Yongming, 2009;Arao et al, 2010). In this sense, several investigations have shown the importance of evaluating the bioaccumulation of metals and aromatic compounds after remediation work and have emphasized that the behavior of the pollutant depends on the specif ic conditions of each region, in some cases, the contaminants can be transferred in the middle and in this way reach the human being, there are also sites in which the hydrocarbons are below the regulatory limit and have negative impacts on the development of some plants, while others are above this limit, they do not present affectations; different researchers have emphasized that in order to restore a site, different alternatives must be evaluated and the long-term eff iciency of each of them must be compared, in such a way that the information generated can serve as a decision-making tool to restore the properties of the site, optimally, feasibly and adequately (Liang et al, 2011;Hou and Al-Tabbaa, 2014;Bolan et al, 2014;Marín-García et al, 2016;Lu et al, 2017).…”

Salinity in soils is a problem that has increased in recent years, in the Mexican southeast one of the main sources associated with these effects is the oil production water, affected congenital water. Although the chemical composition changes between one site and another, it is documented that its components can cause harmful effects on health and ecosystems. To recover the vocation to use recovery areas, different treatments have been established that eliminate standardized parameters, but others that may influence soil quality are not considered. Therefore, two treatment techniques of a soil contaminated experimentally with congenital waters were evaluated, these were; cation exchange and natural attenuation, the evaluation consists in comparing the physical and chemical properties of the control soil, treated and treated after one year, some heavy metals are also determined in all of them. In the results, it is modif ied that the pollutant causes changes in the soil, such as, pH reduction (neutral to acid), porosity (20%), f ield capacity (50%) and organic matter (50%), as well as an increase in salinity (without saline to saline) and densities (10%), it is also increased that the concentrations of Pb, Zn, Ni increase. Na, Fe and V and Ca and K were reduced. Both treatments reduce salinity, but natural attenuation shows better results than cation exchange, mainly in pH, f ield capacity and textures, but with higher concentrations of sodium with respect to the witness in both cases, the metals are below the regulatory limit before and after the treatment, but when compared with control soils a level of increase in V and Pb is noted, because the area is immersed in oil activities, it is advisable to carry out long-term bioaccumulation studies.

“…The only point of concern is the reduction of microbial biomass in both MS and OS soils with N fertilizer and SOFs. The drastic decrease in microbial biomass in SOF treatments could also be from the possible heat and increased pH 43 . Dissociation of SOFs is an exothermic reaction resulting in increased soil pH of the medium due to formation of hydroxide 43 .…”

“…The drastic decrease in microbial biomass in SOF treatments could also be from the possible heat and increased pH 43 . Dissociation of SOFs is an exothermic reaction resulting in increased soil pH of the medium due to formation of hydroxide 43 . At the end of experiment, mineral soil pH measured between 9.80 and 10.00 for CPO and MPO would validate the reasoning.…”

Elevated levels of nitrous oxide (N2O) emissions are a matter of concern in agricultural soils especially when flooding (hypoxic conditions) results from over irrigation or frequent rains. This study is the first to report the use of two solid oxygen fertilizers (SOFs, calcium peroxide and magnesium peroxide) to reduce N2O production in mineral and organic soils amended with N fertilizer in a short-term laboratory incubation besides two biochars. In general, organic soil had greater N2O production than mineral soil. Soils amended with nitrogen fertilizer exhibited increased N2O production, by 74 times in mineral soil and 2 times in organic soil. Both solid oxygen fertilizers in mineral soil (98–99%) and calcium peroxide in organic soil (25%) successfully reduced N2O production than corresponding N fertilized treatments. Additionally, a greater level of available nitrate–N (52–57 and 225 mg kg−1 in mineral and organic soil, respectively) was recorded with the solid oxygen fertilizers. Corn residue biochar with N fertilizer increased N2O production in mineral soil but decreased in organic soil, while pine bark biochar with N did not affect the N2O production in either soil. Depending on soil, appropriate SOFs applied were able to reduce N2O production and maintain greater nitrate–N levels in flooded soil. Thus, solid oxygen fertilizers can potentially be used as an effective way to reduce N2O emission from hypoxic soil in agricultural production systems.

“…Advances have been made recently in the development of materials with which to deliver oxygen to lake bed sediments. Nykänen et al (2012) have demonstrated at the field scale the application of calcium peroxide to manipulate redox conditions at the bed sediment surface which can lead to the reduction of P release to the water column (Lu et al, 2017). However, oxidising conditions might result in undesirable response in V, leading to a release of this metal from bed sediment, as shown by Olszewska et al (2017).…”
