Introduction

This study examines the centralization of heavy metals in six distinct occasional products of soil species collected from five kitchen markets in the Bangladeshi city of Dhaka. The presence of poisonous heavy metals like lead (Pb), cadmium (Cd), chromium (Cr), and arsenic (As) in the delegate tests of six extensively consumed leafy vegetables was not completely established in this focus. The HG-AAS (Hydride Generation Atomic Absorption Spectrometry) method was used to identify arsenic, while the other components, specifically lead, cadmium (Cd), and chromium Except for the lead content of the hyacinth bean (01.09 mg/kg), none of their fixations exceeded the FAO/WHO Maximum Allowable Concentration (MAC) among the investigated leafy foods. Estimated Daily Intake (EDI), cancer-causing and non-cancer-causing risks were assessed using Target Hazard Quotient (THQ) and Hazard Index (HI) to assess the health risks associated with these metals' consumption.

Regular Bodies of Water, Groundwater

As an essential component of a healthy diet, foods grown on the ground are notable. They are low-calorie, low-fat staples that are also high in nutrients, minerals, and other bioactive combinations and a good source of fiber. The prevention of malignant growth is strongly correlated with the extensive consumption of foods grown on the ground in daily life; a disease of the heart; diabetes and bone loss Because of these benefits for medicine, its widespread use has increased recently, which has had a significant financial impact. However, given the unpredictable effects of pesticides, substance composts, and other synthetics, such as heavy metals, on health, consumers today could scarcely be considered suspicious of soil-based products.

New fruits and vegetables, which are highly perishable, were brought to Dhaka from all over Bangladesh. In the city of Dhaka, the significant passage focuses on new soil products. In the past, a testing program was carried out to determine the degree of heavy metal contamination in the soil products that urban tenants brought to Dhaka City for use. Even though the method of inspection was off, this program found the possibility of heavy metal contamination of new soil products without information about the health risks to customers. Modern waste and effluents are being dumped on soils, lakes, waterways, and trenches at random in Bangladesh without any treatment. A portion of the strong waste is frequently utilized in inland fillings. In addition, they pollute the soil, groundwater, and majority of the climate as a whole. In Bangladesh, they put human health, marine life, and harvest production at risk. Copper (Cu), Nickel (Ni), Zinc (Zn), Lead (Pb), Chromium (Cr), and Cadmium (Cd) are just a few of the heavy metals involved.

Effects of Pesticides

The ingestion of significant metals from dirtied soils by plants is imperative in light of the fact that it might be badly designed for the success of clients to outflank the dietary confirmation of a part of these focused on metals (Pb, Cd, Cr, and As) through the contaminated verdant food sources. The accumulation of heavy metals in soils treated with crude city and modern wastewaters or the muck isolated from these waters is currently generally recognized. The utilization of wastewater for cropland has been refined for quite some time. Flooding wastewater to excessively accumulate heavy metals in rural soils can contaminate the soil and affect food quality and safety. Our fundamental metals come primarily from food and water; additionally, these are the channels through which various poisonous metals are introduced to us. Rather than grain or natural item crops, profound metals are expeditiously contained in the palatable bits of verdant vegetables. In order to prevent cross-contamination, new polythene zip-sacks were used for each example during the sample assortment. Weighty metals are taken up by foods grown from the ground and stored in fixations sufficiently high in their eatable and unappetizing parts to cause clinical issues for the creatures and people who consume these metal-rich plants. Polythene zip-sack packs were used to gather the samples, which were appropriately tagged and named. After that, they were carefully stored in a cold box. The collected samples were kept in a chilled box and transported to the research facility as quickly as possible. They were stored in a cooler (-20°C) until they were examined. Each product of the soil weighed 500 g. Only the consumable areas of the example were selected and washed fundamentally with faucet water and deionized water to kill any dirt and soil particles [8]. The examples were then cut into small pieces with a hardened steel blade after being reasonably dried in the air. To obtain a consistent dry weight, the test pieces were dried separately in an electric broiler at 80°C for 48 hours. After that, a mortar and pestle made of earthenware was used to crush each of the three dried examples. After passing through a 2 mm nylon wire lattice, the powdered samples were kept at room temperature before being absorbed into a polyethylene zipped pack.

The examples were first washed with water that had been de-ionized. They were then cut into small pieces to ensure uniformity at that point. Then, 6.0 mL of conc. and 1.0 g of each sample. Channel paper was used to separate the processed examples, and deionized water in a 10 ml volumetric carafe was used to acclimate each example's volume. Finally, the models were investigated keeping a rule supported technique. Because of these benefits for medicine, its widespread use has increased recently, which has important financial consequences. However, given the unpredictable effects of pesticides, compound composts, and other synthetic substances, such as heavy metals, on health, consumers today could scarcely be blamed for being skeptical of soil-based products.
