Abstract
Background and Objective: The trend of developments in the health system and medical education and other related sciences, including environmental health, is a global challenge. In this research educational content of environmental health and its revision were studied from the point of view of students and graduates.
Materials and Methods: The present study was a cross-sectional descriptive study. In this research, through two checklists, the opinions of environmental health students and graduates regarding the necessity of revising the educational content of the field according to the requirements of the time and considering the future situation were investigated with the participation of 441 people. Data analysis was performed using SPSS-22 software.
Results: According to the results, 73.7 percent of participants believed that the educational content of environmental health in Iran has fundamental differences from developed countries. 81.7 percent believed that the educational content provided to environmental health students is not proportional to their duties. Meantime, 91.4 percent of the graduates of environmental health believe that the expected capabilities included in the educational curricula of different degrees of environmental health should be revised. 88.4 percent believed that it is necessary to revise the educational content of this field considering the "change in executive and practical functions of environmental health during the past years".
Conclusion: The overwhelming majority of graduates of the field emphasized the need to revise the educational content of the environmental health field, taking into account the requirements of the time. It is necessary to redefine the field of environmental health in the country according to the changing situation and the emergence of new indicators.

Abstract
Background and Objective: Given the crucial role of milk and its products in human diets, it is imperative to implement effective measures to ensure the safety of milk by minimizing the presence of hazardous pollutants. This study aims to assess the concentration and potential risks associated with lead in raw milk produced in Tehran province.
Materials and Methods: This cross-sectional descriptive study involved the collection of raw milk samples from 24 diverse livestock farms in Tehran province during the winter season of 1401. The samples were analyzed for lead contamination using flame atomic absorption spectrometry. Statistical tests were applied to compare the results with international standards, and subsequent risk assessment was conducted based on the average amounts.
Results: The study revealed that none of the samples exceeded the permissible limit for lead. The mean and standard deviation of lead concentration in the samples was 7 ± 5.8 (ppb), well below the international standard. There was no significant variation in lead levels among the tested livestock farms. The Hazard Quotient (HQ) values for both children and adults were calculated to be less than 1.
Conclusion: The concentration of lead in all samples remained below the permissible limits set by Codex and the Iran Standards Organization, indicating no non-carcinogenic risks associated with milk consumption in terms of lead contamination, as suggested by the calculated HQ values.
