Abstract Background and Objective Outsourcing services to the private sector can be a step towards achieving the goals of community health promotion, job creation, better access to health services, and improving the quality of health […]
Abstract Biofilm formation and antibiotic resistance are the most important ways in which water bacteria such as Pseudomonas aeruginosa are protected against antibacterial agents. The aim of this study was to develop a rapid and […]
Abstract Background Antibiotic-resistant bacteria (ARB) usually enter water sources in different ways, such as via municipal and hospital wastewaters. Because conventional technologies used to treat water inefficient in removing these contaminants (especially antibiotic-resistant genes; ARGs), […]
Abstract Abstract Background and purpose: Identification of risk in hospital waste management have a major role in reducing the cost of surplus and preventing the spread of diseases. In this quantitative analysis, we aimed at […]
Abstract Bottled water is one of the sources of drinking water in many arid and semi-arid countries, including Iran. The greatest concern is the health effects of exposure to excessive nitrate concentrations in drinking water […]
Background Edible coatings are useful method that applied to preserve postharvest quality of production. The coatings can extend the shelf life of products and inhibit microbial growth. Chitosan based coatings are one of the best […]
Abstract Exposure to endotoxin occurs environmentally and occupationally. There are several differences between them in terms of the variety and severity of health outcomes, possible exposed groups and type and route of exposure. Occupational exposures […]
Abstract Novel graphene oxide (GO)-based adsorbent embedded with epichlorohydrin (ECH) as a coupling agent and dimethylamine (DMA) as a ligand (GO-ECH-DMA) were prepared and employed for endotoxin removal from aqueous solutions. The physicochemical properties of […]
Abstract Climate change is a continuous phenomenon that in some conditions it may lead to drought which substantially affects drinking water resources. Also, there may be other associated impacts, such as seawater interruption, water quality […]
Abstract We investigated the removal efficiency of humic acid from aqueous solutions by cotton coated with graphene oxide. This research has been conducted as batch on an experimental scale. A self-arrangement approach was introduced in […]
