“…Use of industrial or municipal wastewater for the irrigation of vegetables by marginal farmers is a common practice in urban and periurban ecosystems of many countries (Alam et al 2003;Bo et al 2009;Chary et al 2008;Chopra and Pathak 2012;Chang et al 2013). Globally, the irrigation by wastewater covers &20 million ha of land (Srinivasan and Reddy 2009).…”

Assessment of potential health risks due to heavy metals through vegetable consumption in a tropical area irrigated by treated wastewater

Consumption of wastewater-irrigated vegetables is a common practice in developing countries including India. The wastewater irrigation gradually raises the contents of heavy metals in soils and vegetables. The consumption of heavy metal-rich vegetables may cause serious risk to the human health. Therefore, quantification of heavy metals in vegetables collected from wastewaterirrigated field is needed as proportion of farmers using wastewater for irrigation is increasing due to scarcity of water. The aim of the present study was to assess the heavy metal accumulation and the potential human health risks associated with consumption of contaminated vegetables irrigated with waste (WWT) and mixed wastewater (MWWT), grown in an agricultural area of Bhagwanpur, near Banaras Hindu University, Varanasi, India. Seven common vegetables growing at two differentially irrigated areas (WWT and MWWT) were considered for the study. At each site, three samples, each from water, soil and different vegetables, were taken. The samples after digestion were analysed for heavy metal contents using atomic absorption spectrophotometer. Heavy metal contents in soils, vegetables, transfer factor (TF) from soil to vegetables, metal pollution index (MPI) and their health risk in form of target hazard quotients (THQs) were calculated. Results showed significantly higher contents of heavy metals in water, soil and vegetable at WWT than MWWT. The TF value of Cd was notably greater in WWT compared to the MWWT. The values of THQ in children and adults were [1 for Pb and Cd in case of all vegetables at both WWT and MWWT. Among the vegetables, MPI was highest for B. vulgaris followed by B. botrytis, B. capitata, R. sativus, B. nigra, A. sativum and S. tuberosum. THQ for both categories were mostly higher for WWT compared at MWWT, suggesting a greater health risk to local residents from vegetable of the former than latter site. The present study suggests regular monitoring of water quality prior to discharge for irrigation uses and also points out to adopt better wastewater management strategies for proper utilization and disposal of wastewater.

“…In addition, the results confirmed that Cu and Zn are deemed to have low mobility in plants (MARSCHNER, 2012). Conversely, the internal transport rate of Cd varies considerably among species (CHOPRA & PATHAK, 2012). As such, results of this study demonstrated low mobility of this metal in M. leucocephalus.…”

Growth and volatile compounds of Martianthus leucocephalus exposed to heavy metal stress.Ciência Rural, v.46, n.12, dez, 2016. Cd (15, 30, ), Cu (30, 60, ) and Zn (150, 300, ) levels on the growth of this species and its volatile compounds production. Apical cuttings were placed in plastic trays containing 6.0L nutrient solution, and after rooting, they were submitted to Cd, Cu and Zn treatments for 15 days. All the metals evaluated reduced the succulence and growth of all parts of M. ABSTRACT Martianthus leucocephalus is found in the semi-arid Northeast of Brazil and has high pharmacological potential due to the production of volatile compounds. This study aimed to evaluate the leucocephalus. This effect was accompanied by the increase of Cd, Cu and Zn concentrations in all plant tissues. Volatile compounds content produced by M. leucocephalus was increased only by Zn (86%).Key words: Lamiaceae, metals, relative growth.

“…The reduced uptake of Cu into the plant tissues in the presence AMF or GSH may be due to efficient chelation or restriction of the metal within the plant rhizosphere (Huang et al, 2005;Mostofa et al, 2014). The availability, mobility, uptake, and translocation of HMs may be dependent on the interactions between a combination of HMs, soil, water, and plants (Singh et al, 2010;Chopra and Pathak, 2012). Singh et al (2010) reported a significantly higher concentration of HMs in plant tissues (root and shoot) collected from CFA-contaminated sites than in uncontaminated sites.…”
