EVALUATION ON PLANTS GROWN IN THE VICINITY OF MUNICIPAL SOLID WASTE (MSW) DUMPING SITE – RANIPET....

The study's goal is to determine the impact of open waste dumping on soil contamination and plant diversity in the vicinity of a municipal solid waste (MSW) dumping site. The current study will focus on three distinct plants that are grown near the Ranipet Municipality's MSW disposal site in Vellore District. Atomic absorption spectroscopy and flame emission spectroscopy are used to investigate the presence of macro and micro nutrients such as Sodium, Potassium, Phosphorous, and Zinc, as well as heavy metals such as Chromium and Cadmium in edible parts (fruits) and leaves of the plants Ribes uva-crispa 'Invicta' L., Artocarpus heterophyllus Lam (jackfruit), and Psidium guajava. To determine the impact of heavy metal pollution, the plants samples were subjected to quantitative phytochemical analysis in terms of total phenolics and total flavonoids. The quantities of Cd and Cr in plants were used to determine the site's metal pollution status, as well as the ability of different plant species to absorb and accumulate metals from the soil. The existence of Phytochemicals in quantifiable amounts suggests that the plants are resistant to heavy metal poisoning. Furthermore, it is discovered that critical plant nutrients are present in higher concentrations and that chromium bioaccumulation is higher in the leaves of plants than in their fruits, but this is within the legal range. Long-term storage of this solid waste, on the other hand, may result in crop contamination due to heavy metal leaching from the dumping site. As a result, more focus should be paid to the potential health dangers posed by heavy metals to residents residing near the MSW disposal site.
