“…Wastewater streams provide an important source of water and nutrients to improve crop production. For example, irrigation of sewage effluent yielded larger winter crops than irrigation with well water, because sewage also supplied nitrogen, phosphorus, potassium, and organic carbon to the soil (Singh et al 2012). 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).…”

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.

“…A cada dia se utiliza mais águas residuárias como alternativa de fonte hídrica, dentre os motivos destaca-se: escassez de água com boa qualidade, rendimento das culturas e o aumento de nutrientes no solo (Singh et al, 2012), diminuição de água residual no meio ambiente visto por Alobaidy et al (2010) e diminuir poluição subterrânea (Muyen et al, 2011). Para a utilização de águas com qualidade físico-química e biológica inferior ao indicado para sistemas de irrigação, é necessário um monitoramento ainda mais preciso e com maior periodicidade, para que não tenha problemas de entupimento e desgaste excessivo dos materiais.…”

RESUMO:Um conceito vindo das indústrias e aplicado na engenharia de irrigação é o uso da estatística de controle de qualidade para monitorar o funcionamento e a qualidade da irrigação temporal. Objetivou-se monitorar a utilização de esgoto doméstico tratado em gotejadores do tipo labirinto, com gráficos de controle de qualidade das somas acumuladas, Cusum. Foi utilizado um modelo de gotejador in line do tipo labirinto submetido a 1188 h de funcionamento com esgoto doméstico tratado. A cada 36 h os gotejadores do sistema foram submetidos à coleta de vazões em diversos pontos, posteriormente foram calculados os coeficientes de uniformidade de aplicação e realizado a construção do gráfico Cusum. A partir da amostra dezessete que ocorre a 576 h de funcionamento, a soma acumulada dos desvios saíram dos limites de controle, indicando que neste tempo de funcionamento a irrigação com esgoto doméstico tratado não está sob controle estatístico, e sugere aplicação de processos para minimizar as fontes de variabilidade incidente. A redução da vazão alvo realizada pela obstrução do sistema na amostra dezessete foi de 8,30%. O gráfico Cusum é uma forma de monitoramento das condições hidráulicas de aplicação na irrigação por gotejamento.

“…On the other hand, the indiscriminate long term use of sewage effl uent for crop production could result in the concentration that may become phytotoxic. The use of sewage water with physical treatment can increase water resources for irrigation which may prove to be benefi cial for agricultural production in India (Singh et al 2012 ). In Italy Cirelli et al ( 2012 ) concluded that the microbiological quality of the products was generally maintained, although the E. coli content in wastewater irrigation was often over the standard.…”

The need for irrigated agriculture is growing day by day and the largest water withdrawals from renewable water resources are for irrigation. In addition, the available water resources are decreasing and we need to use non-conventional water resources for irrigation due to looming water crisis (Raschid-Sally and Jayakody, Drivers and characteristics of wastewater agriculture in developing countries: results from a global assessment. International Water Management Institute, Colombo, 35p, (IWMI Research Report 127), 2008). However, the volume of treating and using wastewater is limited due to the lack of adequate data and knowledge and/or negative effects of improper wastewater management (i.e. use of untreated wastewater). A comprehensive evaluation of what has been done is necessary in order to explore wastewater irrigation and to avoid trial-and-error policies. Although a study of wastewater irrigation from crops, soil, groundwater, health, irrigation equipments, modern technologies, and other environmental aspects is useful, management studies in comparison with other aspects can help lead to more reliable and more extensive fi ndings and fi nally a better decision on using wastewater for irrigation. The chapter presents challenges and prospects that may help decision making for the use of wastewater in irrigation.
