Hospitals are working to create innovation in patient care throughout the world while maintaining high quality standards. Since in implementing this innovation, hospitals have an impact on the natural environment, hospital managers are constantly developing management plans to conserve energy and dispose medical waste properly to reduce the damage to patients, surrounding communities, and the natural environment. Therefore, this study evaluated the important and effective indicators in order to target the measures in the field of hospital environmental management.

This cross-sectional analysis was designed and implemented in 2018 and 2019 in Trita subspecialty hospital in the west of Tehran. To implement this study, ISO 14001 standard was used and ISO 14031 standard was applied to monitor it.

According to the findings, 18 important and basic indicators were defined in the field of environmental performance for the hospital and the relevant indicators were measured. Correction and improvement of indicators was clearly observed in 2018 and 2019. Most of the corrective actions and the most noticeable changes were related to waste.

The use of environmental assessment models along with managerial support for corrective action can protect the environment in the long run and improve public health. Moreover, proper management of the hospital waste can reduce the costs.

This research was aimed to investigate the potential of four halophytes from the Urmia Lacke including Salsola dendroides, Salsola nitraria, Salsola iberica and Halocnemum strobilaceum as soli phytodesalination. For this purpose, soil samples were collected from two soil depths of 0-15 and 15-30 cm inside the ecological patches as well as around it. Our results clearly showed that the studied halophytes could reduce the amount of Na+, Ca2+, and Mg2+ significantly in the first soil depth (p<0.01). However, in the second depth, less affected by the root of species, there were no significant differences in the amounts of these cations in the soil of inside and outside the patches. The absorption of Mg2+, Cl-, Ca2+, Na+ and K+ by underground and aboveground biomass was also investigated. The results of mean comparisons showed that Salsola nitraria and Halocnemum strobilaceum accumulated the highest concentration of magnesium and chlorine in each gram of dry weight biomass. Also, the studied species showed no significant difference in SAR. The amount of these elements were compared in the roots of two species having the highest salt accumulation in aboveground biomass, and the species accumulating lower levels of these elements in roots was introduced. Overall, Halocnemum. strobilaceum showed the highest potential in absorbing salt through roots (soli phytodesalination) as compared to the rest of the species and its cultivation could be recommended for soil improvement and forage production in saline lands.
