“…However, land application of untreated/ treated wastewaters containing phthalic acid esters may over time result in the accumulation of phthalic acid esters in the receiving soils (Table 1). Irrigation with wastewater may not only result in soil contamination through accumulation but also affect the food quality and food safety through the uptake of contaminants by crops (Calderón-Preciado et al 2011). Therefore, it is important that irrigation systems with treated wastewater are designed with the risk of phthalic acid ester pollution in mind.…”

Phthalic acid esters have been used as plasticizers in numerous products and classified as endocrine-disrupting compounds. As China is one of the largest consumers of phthalic acid esters, some human activities may lead to the accumulation of phthalic acid esters in soil and result in contamination. Therefore, it is necessary for us to understand the current contamination status and to identify appropriate remediation technologies. Here, we reviewed the potential sources, distribution, and contamination status of phthalic acid esters in soil. We then described the ecological effect and human risk of phthalic acid esters and finally provided technologies to remediate phthalic acid esters. We found that (1) the application of plastic agricultural films, municipal biosolids, agricultural chemicals, and wastewater irrigation have been identified as the main sources for phthalic acid ester contamination in agricultural soil; (2) the distribution of phthalic acid esters in soils is determined by factors such as anthropogenic behaviors, soil type, properties of phthalic acid esters, seasonal variation, etc.; (3) the concentrations of phthalic acid esters in soil in most regions of China are exceeding the recommended values of soil cleanup guidelines used by the US Environmental Protection Agency (US EPA), causing phthalic acid ester in soils to contaminate vegetables; (4) phthalic acid esters are toxic to soil microbes and enzymes; and (5) phthalic acid ester-contaminated soil can be remedied by degradation, phytoremediation, and adsorption.

“…Although the non-potable direct reuse of treated effluents may have beneficial effects (e.g., addition of nutrients to the soil), irrigation with reclaimed water, for example, may cause sorption of microcontaminants and metals in agricultural crops and the contamination of groundwater sources [11][12][13][14]. Moreover, several studies reported the presence of microcontaminants in agricultural irrigation networks [11,12].…”

The presence of thousands of microcontaminants in wastewaters and their potential risks has drawn a large attention of the scientific community during the last years. The presence of these contaminants is especially controversial when wastewater is considered for reuse because a large number of microcontaminants are frequently not totally removed by conventional wastewater treatment processes. As a contribution to the knowledge in this field, this chapter focuses on the application of four well-known and widely used technologies to the elimination of microcontaminants. Membranes, activated carbon, ozonation, and advanced oxidation processes (AOPs) are deeply reviewed to assess their efficiency and safety in the elimination of these contaminants from wastewater effluents. A brief description of each technology is presented together with a review of their real application, mostly in wastewater treatment plants (WWTPs). A deep analysis of the found data allows to conclude that the four presented alternatives can be useful for microcontaminant mitigation although none of them seem to be a universal barrier for microcontaminants when used separately. In addition, each technology presents drawbacks which demand further research to be overcome. Depending on the final use of reclaimed water, the treatment may require the combination of several of the studied technologies although that results in an economic impact which cannot be neglected.

“…Biosolids (high quality, stabilized sewage sludges) are commonly used to improve the soil nutrient content for crop growth in agriculture; in addition, their OM improves soil fertility. However, many pharmaceutical and personal care products, endocrine-disrupting compounds and other emerging contaminants have been detected in the discharge from wastewater treatment plants, indicating their presence in biosolids (Sabourin et al, 2012;Mohapatra et al, 2016), which can be concentrated in crops when using wastewater for irrigation (Calderón-Preciado et al, 2011). Recently, special attention has been paid to studying the efficiency of different waste treatments (composting and anaerobic digestion) for the degradation of veterinary antibiotics and pharmaceuticals (Carballa et al, 2007;Ho et al, 2013;Mitchell et al, 2015;Wang et al, 2015;Butkovskyi et al, 2016).…”
