Context: Noise is considered one of the most pervasive and harmful agents in crowded cities. The aim of this study was to determine the exposure rate to noise POLLUTION of residents on the main streets of Zahedan city in southeastern Iran and the knowledge and attitudes of these residents concerning noise.Evidence Acquisition: Noise was measured for three consecutive weeks in the October-November areas of the city in 31 test locations, using a CEL-440 Classic sound level meter and analyzer during the noisiest hours of the day (07:00 to 22:00). Using a validated questionnaire, data were collected from 400 subjects to estimate their knowledge’s and attitudes about noise POLLUTION.Results: The average noise level in the main city streets during the day was 75 ± 2.96 d B. The mean age of participants was 31.9 ± 11 years. Approximately 82.3% of the subjects tested reported that street noise POLLUTION was too high, and 48% suggested that the best way to decrease city noise POLLUTION was to enhance people’s knowledge of the problem. Furthermore, 65.8% of the subjects stated that street noise is a cause of stress. There was a significant association between noise levels and subjects’ sleepiness (P<0.05). In addition, noise POLLUTION in Zahedan city streets was found to be higher than standard levels.Conclusions: It was concluded that appropriate traffic management and a health promotion program are essential for increasing the residents’ understanding about how to improve the current noise POLLUTION situation.

Soil POLLUTION has increasing risks for human health and environment. Heavy elements are considered among the most important pollutants in the environment, which have been highly concerned in the last few decades. The accumulation of heavy elements in the soil, especially in agricultural fields, is gradual and the concentration of heavy elements can reach a level that threatens human food security. Every year, thousands of tons of these elements, which are caused by urban, industrial, and agricultural activities, enter the soil. The study of different researchers inside the country shows that the intensification of industrial activities, on one hand, and the non-compliance of environmental issues and standards by some of the industrial owners, on the other hand, has caused environmental POLLUTION in some areas of the country. Soil is one of the important components of earth's bio-travel and plays an important role in the health of humans and animals. Soil not only plays an important role in the production of food and clothing, but also has a significant effect on maintaining the environmental quality. Therefore, soil contamination by chemicals is one of the most important biological issues. In the last few decades, with the progress of industry, the amount of toxic elements in the soil has been increased. Municipal and industrial effluents, solid wastes from various urban, industrial and agricultural activities, various fertilizers, and chemical poisons are important sources of soil POLLUTION with toxic elements.

Air POLLUTION is the fourth leading cause of premature death after hypertension, smoking and malnutrition and is the second leading cause of death from non-communicable diseases after smoking (1-3). Increased air POLLUTION can increase the vulnerability of the respiratory system, and poor air quality is a serious risk for acute and chronic respiratory diseases and cardiovascular disease. Also Exposure to air POLLUTION causes underlying diseases such as high blood pressure, diabetes, cardiovascular and respiratory diseases, and as a result these underlying diseases increase the vulnerability to Coronavirus disease 2019 (4). People with the underlying disease and living in contaminated areas are at higher risk for coronary heart disease, and studies show that air POLLUTION is a contributing factor to diseases such as the flu and covid-19. Airborne particles increase Coronavirus disease 2019 mortality by up to 6%, ozone up to 7% and nitrogen dioxide up to 15%. When different dust particles increase in the air and the virus spreads in the air,For example, The virus has more chance to spread to other people when talking, coughing and sneezing(5).
