“…The red cluster refers to the pollution of water bodies. In Mexico, more than half of the waste water is not treated [46]. The uncontrolled discharging of untreated, reused water can generate negative effects derived from the pollution of water bodies and agricultural soils [47].…”

The development of agricultural activity in Mexico is generating environmental externalities that could compromise its future. One of the principal challenges facing the Mexican agricultural sector is to find a way to continue growing without jeopardising the availability and quality of its water resources. The objective of this article is to analyse the dynamics of the research on the use of water in agriculture in Mexico and its sustainable management. To do this, a review and a bibliometric analysis have been carried out on a sample of 1490 articles. The results show that the research has focused on the pollution of water bodies, climate change, the quality of water, the application of technology in order to make water use more efficient, biodiversity, erosion, agronomic practices that reduce water consumption, underground water sources, and conservation agriculture. Although research focusing on sustainability is still in its infancy, it has become a priority field. A gap in the research has been detected in terms of the economic and social dimensions of sustainability. There is also a lack of holistic studies that include all three of the pillars of sustainability (environmental, economic, and social).

“…En este trabajo, los lodos residuales provienen de una planta de tratamiento con lodos activados y las aguas residuales son mayoritariamente de origen urbano, con escasa presencia de residuos industriales que aporten cantidades importantes de metales tóxicos. En trabajos previos sobre las aguas residuales de la zona (Robledo et al, 2017), se detectaron bajas concentraciones de los metales Cu, Mn y Zn (1.1 a 1.2 mg L -1 ) en influentes de la planta de tratamiento de aguas residuales (PTAR) y una mayor concentración de Fe (media de 8.7 mg L -1 ). La concentración de estos metales se comparó con los límites establecidos en la Norma Oficial Mexicana (NOM-004- SEMARNAT-2000SEMARNAT- , 2003 para lodos residuales que pueden emplearse como mejoradores de suelos agrícolas, esto en virtud de que en el país no se dispone de normatividad para biochars de lodos residuales y su uso agrícola.…”

Pyrolysis treatment of sewage sludge to generate biochar is one of the current alternatives for environmental management of this waste. The treatment transforms sewage sludge into biochar, conserves some of the characteristics that give it an important agronomic value and reduces its pathogen content. The objective of this study was to analyze the potential use of the sewage sludge biochar obtained from the wastewater treatment plant (WWTP) of Morelia, Michoacán, México, as an agricultural soil improver considering the physical-chemical properties of the material and its content of nutrients and heavy metals as indicators. The sewage sludge was subjected to pyrolysis (SSB) in an experimental scale reactor that uses solar energy, with six residence times and temperature of 280 to 355 oC. The parameters analyzed were: pH EC, OM, Cu, Mn, Zn, Fe available (DTPA and EDTA), elemental composition (C, N, O, Ca, Mg, Na, K, P, S, Cl, Si, Al, Fe, Mn, Cu, Zn, Ti, Ni, Cr, Cd and Pb). The EC of the SSB obtained was from 592 to 5240 μS cm‑1, pH = 6.33 to 7.02, OM = 3.8 to 5.6%, high contents of C, N, P (31 to 38%, 6.5 to 7.7% and 37.7 to 48.8 g kg‑1, respectively), low Na/Ca ratio and a low content of total and available heavy metals. The properties of the SSB obtained indicate that it can be used as an agricultural soil improver since it is a material with high nutrient content and low environmental risk in terms of its low heavy metal content. These results should be complemented with studies on the response of plants to BLR, monitoring of physical-chemical conditions and analysis of organic contaminants in soil and water where this material is applied.

“…Other earlier studies have proven that wastewater contains elements that are potentially toxic for aquatic organisms (Robledo-Zacarías et al, 2017) and heavy metals, added to the soil by irrigation, accumulate on the arable layer of agricultural soils (Siebe, 1994;Prieto-García et al, 2007;Flores-Magdaleno et al, 2011) and can be absorbed and accumulated in plants (Vázquez-Alarcón et al, 2001); furthermore, contact with wastewater affects the health of the overall population (Cifuentes et al, 1994;Cifuentes et al, 2000). On the other hand, wastewater poured into receiving bodies is a high risk for human health and the environment, since medications and narcotics have been found in wastewaters, and can potentially cause toxic effects (even in low concentrations) in aquatic organisms and soil microorganisms (Robledo-Zacarías et al, 2017). (Cuellar-Carrasco et al, 2015;López-García et al, 2016), therefore the use of wastewater in agriculture can have negative effects on the soil and crops regarding salinity and sodicity (Fuentes-Rivas et al, 2017).…”

Introduction: Mexico City generates an approximate volume of wastewater of 57 m3 s-1, the wastewater is conduct by the drainage network: main channel-west interceptor-central emitter, and conducted to Hidalgo State, during it course, an important volume is poured into irrigation channels and is used for crop irrigation in the Mezquital Valley.Method: in this study, nitrate (NO3-), phosphate (PO4-3) boron (B3+) and chloride (Cl-) content in 188 wastewater samples was determined. The objective was to assessment the risk of toxicity by specific ions (B3+ and Cl-) and the nutrients content (N, P, K, Ca y Mg) in wastewater used for crop irrigation.Results: the nitrate (NO3-) concentration was very heterogeneous (CV=59.83 %) and this was attributed to the lixiviation of nitrogen fertilizers. The maximum phosphate (PO4-3) value was 65.7 mg L-1, and its concentration was attributed to the discharge of household wastewater. The boron concentration (B3+) was less than 1.88 mg L-1. The risk of toxicity due to the use of wastewater in irrigation may cause a decrease the yield of sensitive crops, such as beans.Conclusion: untreated wastewater used in irrigation in Mezquital Valley, may cause toxicity problems in some crops; the nitrate and phosphate concentrations in wastewater of the Mexico City-Mezquital Valley drainage network were high, and these were attributed to the discharges of domestic and industrial wastewaters and to agricultural drainage, high concentrations of nitrate and phosphate represent a risk for aquatic organisms due to pollution and the possible eutrophication of water bodies. The risk of toxicity by B3+ and Cl-can have a negative effect on the germination and yield of bean crops.
