  The aim of this study was to compare the content of two commonly used poisons in Guilan province in order to increase the crops, especially rice, in water used by residents of Gilan in spring. For this purpose, 20 wells were selected in the villages of Guilan. The extraction process was carried out using liquid and N-hexane-dichloromethane (1: 1) phases for analysis. The extraction product was injected into a gas chromatograph with an electron capture detector (GC-ECD) for measurement. The sampling and measurement process was carried out. Quantitative measurements were carried out using external standard methods. The studies carried out confirmed that in the study chapter, the study of the content of Hinosan and Butachlor pesticides is not more than standard and more acceptable, but due to their toxicity and their long-term effects on creatures Consumers, especially humans, it be used continuous monitoring of their amount in water by residents.

  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

  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.
