Title : ASSESSMENT OF HEAVY METALLIC TOXICITY IN CONTAMINATED SOIL AND VEGGIES IRRIGATED WITH SEWAGE EFFLUENT IN SIKAR DISTRICT
Ishita Bari, Dr. Kavita Yadav

Abstract :

The Sikar District in Rajasthan, India, is currently facing a severe environmental crisis due to the agricultural use of sewage effluent, which contains heavy metals like lead, cadmium, mercury, and arsenic, sourced from domestic and industrial origins (Dhaka et al., 2023; Shyam et al., 2011). This practice has become common in the region due to water scarcity and the lack of alternative irrigation sources. Heavy metals introduced into the soil tend to persist and accumulate over time, as they tightly bind to soil particles through adsorption, making remediation challenging (Dhaka et al., 2023). Consequently, the levels of heavy metals in the soil have continued to rise, leading to potential health hazards. The proposed research will beencompass a wide range of sampling sites, accounting for variations in irrigation practices, soil types, and crop varieties. Advanced analytical techniques such as atomic absorption spectroscopy and inductively coupled plasma mass spectrometry should be employed to accurately measure heavy metal concentrations in soil and vegetables (Dhaka et al., 2023). Additionally, the research will be considered seasonal variations in heavy metal accumulation and assess the impact of agricultural practices on contamination levels. Specific farming techniques or crop rotations that can mitigate heavy metal uptake by plants should also be explored. Furthermore, a comprehensive risk assessment will be conducted to estimate daily heavy metal intake through vegetable consumption and compare it to established safety thresholds and guidelines set by organizations like the World Health Organization (WHO) and the Food and Agriculture Organization (FAO). Efforts to remediate and mitigate heavy metal contamination should also be explored. Phytoremediation, which uses specific plants to absorb and accumulate heavy metals, can be considered a sustainable means to reduce soil contamination. Raising awareness among local farmers about the risks associated with sewage effluent irrigation and promoting alternative, safer irrigation practices should be a priority (Dhaka et al., 2023).The proposed research will conduct in Sikar District to address heavy metal contamination, assess health risks, provide sustainable solutions, contribute to environmental health knowledge, and empower local communities. This multidisciplinary effort underscores the urgency of addressing environmental degradation and public health challenges in the face of water scarcity and contamination issues. It is not only a local concern but also a crucial case study that can inform similar challenges faced by regions globally, emphasizing the need for responsible environmental stewardship and sustainable agricultural practices.
