Anthropogenic activities such as industry are primary sources of heavy metals and other elements, which can contaminate the surrounding environment. One of the most significant problems is soil and air pollution, which is harmful to humans and animals because it accumulates hazardous metals in plant tissue when growing in contaminated environments. This study identified and evaluated the magnitude of heavy metal contamination in leaves of plant samples at 22 locations, which consist of radii of 0.5-1; 3; and 5 KM from the industrial site in Gresik, East Java. The level of elements in the plant has been determined using Total X-Ray Fluorescence. An estimation of human health risks from consuming the plants was also conducted. The analysis result of the element content in plant samples was in the following order: Pb < Cu < Zn < Mn < Fe. The range of concentrations for each element in the samples was obtained and compared with the permissible levels set by the Food and Agricultural Organization (FAO) and World Health Organization (WHO) standards. The results obtained from this analysis revealed that Mn, Fe, Cu, Zn, and Pb are in general accordance with the recommended standard, and the hazard quotient (HQ) was lower than 1 for a crop, indicating no appreciable health risk due to the consumption of these samples in the study area.
