Abstract
The excessive application of fertilizers and of polluted irrigation water increases the trace metal level in an agricultural ecosystem. This study aimed to assess the concentrations of trace metals (Fe, Cu, Mn, and Zn) in irrigation water, field soil and crop plants. The contents of metals were analyzed by Atomic Absorption Spectroscopy. The range and hierarchy of trace metals concentration (µg/ml) in irrigation water are as follows, Fe (2.16 - 1. 53) > Zn (0.30 - 0.17) > Cu (0.18 - 0.11) > Mn (0.11-0.09). The concentration (µg/g) range in field soil showed in an order as Fe (9000- 6961.5) > Mn (984.6-408.9) > Cu (698.5-26.3) > Zn (145.3- 22.9). Moreover, crop plant parts showed maximum concentration (µg/g.dry weight) range for metal Fe (516.3 - 126.7) followed by Mn (169.7-0.4), Zn (78.8- 50) and least for metal Cu (70.5- 4.1). It was noticed that the Fe concentration in irrigation water is higher than the water quality standards proposed by the Food and Agriculture Organization. Furthermore, the field soil exhibited more Cu, and crops have accumulated excess Fe and Cu than the Indian and European Union guidelines. Further, we reported that among the all plant part, leaves are more prone to accumulate trace metals. The value of the transfer factor indicates that plant has low bioaccumulation potential for studied trace metals. Whereas the accumulation index shows that there is a significant Cu contamination in the field soil. So we suggest that farmers should avoid the application of copper-rich fertilizers.
Highlights
The range and hierarchy of trace metals concentration The environmental pollution with trace metals has in irrigation water are as follows, Fe (2.16 - 1. 53) > become a worldwide problem during recent years
The the environmental pollutants, trace metals are of particular concentration range in field soil showed in an order concern, because of their bioaccumulation potential in as Fe (9000- 6961.5) > Mn (984.6-408.9) > Cu ecosystems [1,2]
The content of trace metals such as Fe, Cu, Mn and Zn were assessed in various irrigation water sources such as Bore wells, Wells and Ujjani reservoir. (Figure1)
Summary
The range and hierarchy of trace metals concentration The environmental pollution with trace metals has (μg/ml) in irrigation water are as follows, Fe (2.16 - 1. 53) > become a worldwide problem during recent years. The range and hierarchy of trace metals concentration The environmental pollution with trace metals has (μg/ml) in irrigation water are as follows, Fe The the environmental pollutants, trace metals are of particular concentration (μg/g) range in field soil showed in an order concern, because of their bioaccumulation potential in as Fe (9000- 6961.5) > Mn (984.6-408.9) > Cu ecosystems [1,2]. Crop plant parts ecosystems is usually studied by measuring their showed maximum concentration (μg/g.dry weight) range concentrations in water, sediments and biota. It was noticed for metal Fe (516.3 - 126.7) followed by Mn (169.7-0.4), that their concentrations generally exist low levels in water
