    "description": "<p>Health implications for the population due to consuming contaminated crops have been a great concern worldwide. This study aimed to measure the levels of potential toxic elements in lentils and their growing soil in Dawunt Woreda, Ethiopia. Accordingly, 15 soil samples along with the lentil samples were collected to measure the level of potential toxic elements, including chromium (Cr),manganese(Mn),iron(Fe),lead(Pb),cadmium(Cd),copper(Cu),and cobalt(Co),by using an inductively coupled plasma<br>\noptical emission spectrometer and for assessing the potential ecological and human health risk. *e wet digestion method using<br>\naquaregia (HCl/HNO33:1)was employed for soil and lentil sample preparation. The mean concentrations of Fe, Mn, Co, Cu, Cd,<br>\nPb, and Cr in the lentil sample were 60.4,9.68,0.75,5.7,0.25,0.9,and1.15mg/kg, respectively. In soil, the mean concentrations of<br>\nFe, Mn, Co, Cu, Cd, Pb, and Cr were 649,19.9,3.32,40.0,15.2,1.83,and 69.1mg/kg, respectively. All of the potential toxic metals<br>\nin agricultural soil and lentil samples were found to be below the reference level set by the World Health Organization, except Cd,<br>\nin the soil samples. Five single metal and three cumulative pollution index parameters were employed for the data and results<br>\nshowed that Fe,Cu,and Cr moderately pollute the soil and are highly contaminated by Cd. The cumulative pollution indices also<br>\nconfirmed that the extent of soil pollution varied from highly contaminated to moderate contamination. The possible health risks<br>\nat various exposure routes have also been estimated. The single-metal and cumulative-metals health risks (cancer and non-cancer)<br>\nof adults and children due to chronic exposure to soil and consumption of lentils were estimated using the health quotient and<br>\nhealth index values as per the United States Environmental Protection Agency guidelines. Thus, the results revealed no significant<br>\nadverse health risks (cancer and non cancer) for adults and children. Therefore, the inhabitants in the study area have no<br>\nsignificant health impacts due to either the consumption of lentil crops or exposure to agricultural soil particles.</p>",
