Their toxicity depends on several factors including the dose, route of exposure, and chemical species, as well as the age, gender, genetcs, and nutritonal status of exposed individuals. In this research, we tried assessing some pointed heavy metals such as nickel, arsenic, lead, zinc, and cadmium which were prepared and analyzed in chicken liver, thigh, and breast muscles in Lahijan city. Heavy metal concentratons are associated with the use of inductvely coupled plasma atomic emission spectroscopy (ICP-OES). The accessed results expressed the higher rates of heavy metals studied in chicken in some cases compare as world regulaton standards. Also, the highest amount of heavy metals was in liver tssue. Keywords: Food safety; Heavy metals; Chicken; Risk assessment Introducton With the development of human societes and the change in the human lifestyle, it has caused many problems for the environment [1-6]. Plastcs, industrial efuents and sewage have polluted the water and caused many problems for vegetaton, animals, and humans [7-24]. The extncton of many animal and plant species is part of this human negligence. These issues cause new diseases and threaten human health. Nutriton is a key part of human health. Protein products are an essental dietary requirement. Among protein products, chicken is one of the most widely consumed foods due to its easy availability and high nutritonal value, so the health of the meat consumed is very important. One of the most important chemical contaminants is heavy metals, causing irreparable damage [25]. If excessive amounts of heavy metals are received through food, due to their accumulatve propertes, high stability and toxic efects can pose a serious threat to human health [26-42]. Because these compounds are not metabolized in the body, they can be stored in body tssues such as muscles and bones. Heavy metals have the potental to cause diseases such as mental retardaton, hearing impairment, immune system dysfuncton, brain diseases, blindness, muscle weakness and cancer [27,28-41]. Heavy metals enter the food chain through natural and unnatural pathways. Natural pathways such as mineral erosion, wind, river, groundwater, and volcanic actvity. Also, unnatural pathways such as industrial and domestc sewage, pestcides, mines, factory waste, fuel combuston, metal platng and chemical industries. Therefore, there are diferent ways to contaminate chicken meat, such as contaminaton of diet, water, air and soil. In this study, the concentratons of heavy metals such as nickel, arsenic, lead, zinc, and cadmium in chicken liver, thigh, and breast muscles in Lahijan city (north of Iran) were investgated using inductvely coupled plasma atomic emission spectroscopy (ICP-OES).
