The aim of this research is to measure the quality of environmental health of recreational and natural sports swimming pools with a risk management approach in Gilan Province. The study was descriptive - cross-sectional, and three selected sites were sampled. Microbial parameters, temperature and PH were measured. Microbial tests were carried out according to national standards in the laboratory. It was used to analyze data from standard tables related to pollutants and compare them to existing data. SPSS software was used to analyze data from experiments. Two William fine quantitative methods and the risk assessment table technique were used to assess risk. The results showed that the burden of microbial contamination in the Anzali swamp was higher than other sites. In other words, the most polluted sites in Gilan Province were the Anzali wetland, the Kiasar wetland and, at the end, the eyeglass wetland, respectively. Also, the average number of total cliform and cliform, respectively 375 and 109 MPN in 100 ml of samples, and Enterococcus of the rivers 7/17 CFU in 100 ml of samples were observed. The average pH was 89/7, which is within the standard range. On the other hand, the average water temperature measured in these natural swimming pools is 4/25 degrees Celsius, which is within the standard range. It was found that the type of risk "outstanding", the level of aspect "ultimate" and the control required were "appropriate control action and the necessity of corrective action".

The environment of the seas is one of the global concerns, the effects and consequences of which cannot be hidden in the political, economic,and security fields of the coastal countries or all the governments of the world.This is because today most of the countries of the world benefit directly or indirectly from the benefits of the seas.Based on this, the concern of the present research is to be able to address the responsibility of the coastal states in protecting the environment of the seas by relying on the principle of participation.The question of the current research is,what are the solutions to make the coastal states responsible for the area of the marine environment?In line with this question,the findings of the present research have shown that making the coastal states responsible requires creating a balance between the economic interests of the states and environmental groups.Also,relying on scientific and research findings concerning the opinion of experts,the principles of international maritime law,and also modeling some regional treaties such as European maritime laws or restrictions imposed by the Australian government,is a suitable support for Identifying the rights and duties of coastal states. Also,the participation of the coastal states automatically and with their supervision is not a solution. This is because the coastal states have interests in marine resources, and in return, the role of non-governmental organizations, civil society, and free media should be taken into account to identify the environmental problems of the seas and also provide solutions from them citing cases of pollution, the contribution of each government and The amount of responsibility of that government is specific. In the current research, due to the critical nature of the topics, the theoretical framework of problem-solving, which originates from critical theory, was used. Also, the research method is descriptive and analytical using library tools.

Exploiting the bed and subbed of the seas which are outside the governments’ sovereignty is always discussed since the countries severely need to these resources and the technological progress makes it possible to exploit these areas. Present study aims to respond this question that how resources of bed and subbed of the seas outside governments’ sovereignty are exploit based on law perspective, and how can analyze juridical attitude in this issue. In law perspective, according to the 1982 Convention on the Law of the Seas, these areas are the common heritage of humanity and International Seabed Authority is responsible in this field. In Islamic jurisprudence, exploitation of properties which do not belong to a specific person and freely are in access the public is named Anfal. But the bed and subbed of the seas are not included in any of the territories such as Dar al-Harb defined by the jurists, because no government have the right to claim sovereignty over these areas, and Dar al-Kofr is not in charge of these areas either. It is necessary to act based on international treaties and customary in such a situation. It means that Dar al-Islam is committed to act in accordance with existing international treaties and customary. Even if Dar al-Islam has not accepted any treaties regarding the bed and subbed of the seas, it is committed to implement international regulations based on international customary since international customary has known the bed and subbed of the seas outside the governments’ sovereignty as the common heritage of humanity.

The purpose of this study is to determine the number of tourists permitted for the mountainous areas of northern Shahroud. The research method is analytical -survey. Initially, by registering ground points, the study was precisely determined. The area of ​​the study area is 430 hectares. Standard relationships were used to identify zones and recreation classes. A researcher -made questionnaire and 384 questionnaires were used to measure management restrictions. The results showed that the study area has two types of extensive and intensive recreation and 6 classes. The study site scored 2.22 out of 5 based on user and local community votes. Therefore; the region has 44.4% of the minimum capabilities required to achieve the desired goals. Also, the capacity of the physical, real and effective carrying capacity is 2859500, 632235 and 278183, respectively. In general, determining the carrying capacity is one of the important managerial and legal parameters in the protection of natural ecosystems.
