  Due to the increase in human activities, the destructive impact on the environment is not limited to a particular region of the world. Including the destructive impacts are entering non-native plant species around the world that during the 200 years ago with the spread of agriculture, increase the exchange of goods, increased human activities as well as increasing environmental destruction, it's increasing. Although only a limited number of non-native species can be invasive, the negative effects of these species on natural and crop communities, human and animal health, and the changing ecosystem characteristics are so high that the research process is constantly expanding in this regard. One of the damages, which has received considerable attention in recent years, is the problem of the introduction of non-native (invasive) plant species into natural ecosystems, but not all non-native species are harmful. Sometimes non-native species are well absorbed by the ecosystem and positioned like native species. But invasive species are species that are not native ecosystems, and their entry causes economic, environmental or human health damage. In this study, the ecological risk assessment of aggressive plants will be provided and suitable strategies for controlling entry and risk reduction will be presented. Manuscript profile

  Environmental risk assessment is a further step of environmental impact assessment and analyze different aspects of risk, while understanding the Environmental impact zone, the environmental sensitivity of the area affected by special environmental values as well as analysis and risk assessment district is considered. To accomplish this study first by using of field investigation the activities which leads to risk in construction of Caspian port water front were identified and in order to extract the significant risks the specialists questioner (Delphi) was used. Finally among the identified risks, 10 environmental risks were chosen for prioritizing.After identifying the risks, indicators such as probability, severity of risk and the sensibility of the environment were selected as prioritizing criteria. AHP method and ECPRO 2000 software, for determining the risk probability, for determination the severity of risk scores and the reference texts for determining the values of sensitivity were applied. After determining the indicators, the TOPSIS software was used to risk prioritizing. The results of prioritizing studied risk showed that the highest risk is related to increased turbidity, deformation of substrate and water pollution are with weights 0.938, 0.898 and 0.662 respectively.

  EcoRA, which is aimed at appraising a wide range of undesirable impacts on ecosystems exposed to a possible eco-environmental hazard, has been highly recommended for environmental decision-making. In this paper reviews the development history of ecological risk assessment (EcoRA) and presents a perspective for EcoRA and management. In addition, regional EcoRA needs to make further efforts, especially in theoretical study, uncertainty analysis, integrated use of GIS software and comprehensive risk assessment at regional scale in the future work.

  In this research, in order to investigate the scope of the effect of two types of fire, Flash Fire and Jet Fire, and to determine the individual and collective risk related to the gas tanks of South Pars refineries, the quantitative risk assessment method was used using PHAST software. To obtain reproducibility for the inlet and outlet valve flange leakage scenario, all connections in the path were examined separately for each scenario and their reproducibility was calculated. The results related to the gas tanks of South Pars refineries showed that among the leaks, the leakage related to the inlet valve flange and the outlet valve flange, according to their location (close to the car parking lot and vehicle traffic road as well as the traffic route) people and buildings around it) is more important. The individual risk contour diagram is the result of the combination of two scenarios, inlet valve and outlet valve, which shows the amount of deaths per year within the specified limits. This means that the collective risk of the area under investigation is high. Considering the conditions in the South Pars Refinery in terms of regional weather conditions, wind speed and direction, prevailing wind direction, the location of the buildings in the station and its population distribution, we come to the conclusion that in the event of a leakage incident, the consequences It is in the form of release of flammable gas and two possible types of fire, Jet Fire and Flash Fire.
