Heavy metal contaminated soil, water, and vegetables in northeastern Iran: potential health risk factors.

Purpose: This study was designed to measure the concentrations of heavy (Pb, Cu, Fe, Ni, and Zn) metals in water, soil, and frequently edible leafy vegetables in the Iranian population and assessed the carcinogenic and non-carcinogenic health risk in consumers.

Methods: The samples of soil, water, and vegetables were collected from forms near the Tehran-Mashhad highway in Neyshabur, Iran. The content of heavy metals in the samples was analyzed using Atomic Absorption Spectrophotometry.

Development a new index for littered waste assessment in different environments: A study on coastal and urban areas of northern Iran (Caspian Sea).

The coastal pollution has been evaluated using indexes like Clean Coast Index (CCI) in many countries. In this study, several coasts and urban areas in northern of Iran along the Caspian Sea, were assessed in terms of number and composition of litters. Furthermore, Clean Environment Index (CEI) was used for the first time to interpret the results.
