Today, most parts of different nanotechnologies are growing and developing without any special rules and regulations. This could result in undesirable changes in the environment and affect workers in indoor and outdoor workplaces. Carbon-based nanoparticles, such as fullerenes, nanotubes, the oxides of metals such as iron and titanium, and natural inorganic compounds, including asbestos and quartz, can have biological effects on the environment and human health. The risk assessment of such nanoparticles requires evaluation of their mobility, reactivity, environmental toxicity, and stability. With the increasing use of nanoparticles for commercial and industrial purposes, the debate becomes whether the numerous benefits of nanoparticles can overcome the economic costs, environmental impacts, and unknown risks resulting from their use. To date, few studies have been conducted on the toxic and environmental effects that result from direct and indirect exposure to nanoparticles, and there are no clear standards to determine their effects. Lack of technical information in this regard has provided an appropriate context for supporters and opponents of nanoparticles to present contradictory and ill-considered results. Such an uncertain atmosphere has caused increased concerns about the effects of nanoparticles. Therefore, adequate studies to determine the exact, real risks of the use of nanoparticles are required. The information resulting from these studies can be useful in minimizing the environmental hazards that could arise from the use of nanoparticles. Thus, this paper briefly explains the classification of environmental nanoparticles and how to deal with their formation, diffusion, environmental fate and impacts, and our exposure to them.

The worldwide spread of COVID-19 as an emerging, rapidly evolving situation, and the dramatic need of urgent medicine or vaccine, has rapidly brought new hypotheses for pathophysiology and potential medicinal agents to the fore. It is crucial that the research community provide a way to publish this research in a timely manner.
To contribute to this important public health discussion, the Electronic Physician Journal is excited to announce a fast-track procedure to help researchers publish their articles on COVID-19 related subjects that fall under the broad definition of public health, internal medicine, and pharmacology. We are especially welcome to all hypotheses about the pathological basis of the COVID-19 infection and the possible characteristics of potential medicine and vaccine. Submit your manuscript here
The 6th World Conference on Research Integrity (WCRI) is to be held on June 2-5, 2019 in Hong Kong.
The WCRI is the largest and most significant international conference on research integrity. Since the first conference in Lisbon in 2007, it has given researchers, teachers, funding agencies, government officials, journal editors, senior administrators, and research students opportunities to share experiences and to discuss and promote integrity in research.
