The present study was designed to determine the levels of heavy metals (Cu, Pb, Ni, Cr, Zn, Mn, Cd, and Co), Mn, and As in Iranian-grown rice and imported rice consumed in Neyshabur City. For this research, 90 samples from 30 different brands widely consumed in this city were collected. The content of heavy metals and the health risks associated with their use were then studied.

The findings of the GC-MS analysis revealed the presence of nicotine, its derivatives, and several other toxic chemicals that are hazardous to human health. Furthermore, the content of 34 elements in four brands of snuff consumed in Neyshabur City was determined by ICP-OES analysis (with five repetitions).

This study aimed to determine and analyze heavy metal pollution in the street dust of Neyshabur city of Iran. In this regard, the concentration of ten heavy metals, including Al, Fe, Mn, Zn, Cu, Cr, Ni, Pb, Co, and Cd, was measured at 60 street dust samples. The samples from Neyshabur city in three zones were collected, including high traffic, low traffic, and rural.

The risk of newly emerging diseases is constantly present in a world where changes occur significantly in climatic, commercial, and ecological conditions, in addition to the development of biomedical investigations in new situations. An epidemic respiratory disease instigated by a new coronavirus was initially identified in and has resulted in the current global dissemination. This viral strain and its related disease has been termed "SARS-CoV-2" and "coronavirus disease 2019" (abbreviated "COVID-19" or "2019-nCoV"), respectively, which is transmitted simply between individuals.

The present research is an attempt to assess the pollution status of heavy metals including As, Cd, Cr, Ni, and Pb using various indices like contamination factor (CF), pollution index (I), and geo-accumulation index (I). In total, 60 surface soil samples were collected from four area (north, south, east, and west) in Khayyam industrial zone from depths of 10-20 cm.

Heavy metals attract a great deal of attention nowadays due to their potential accumulation in living creatures and transference in the food chain. Sediments of water reservoirs are considered to be a source of accumulation of these metals that develop in response to human activities and soil erosion. This study collected 180 samples of the surface sediments of water reservoir 1 at Chahnimeh in Sistan.

In the present study, 180 sediment samples were collected from the Chahnimeh 1 reservoir to investigate the concentration of metal and sequential extraction. Five geochemical phases (exchangeable fraction, carbonate fraction, Fe/Mn oxide fraction, organic fraction and residual fraction) for the determination of the speciation of heavy metals (Zn, Fe, Cd, Pb, Mn, Ni) as proposed by Tessier was applied to sediments collected from Chahnimeh 1. Results were obtained for nickel and cadmium, as over 40 % of metal was present in the exchangeable phase and bound to carbonate.
