Abstract:
Ocean-scale monitoring of pollution is challenging. Seabirds are useful indicators because they travel over a broad foraging range. Nevertheless, this coarse spatial resolution is not fine enough to discriminate pollution in a finer scale. Previous studies have demonstrated that pollution levels are higher in the Sea of Japan and South and East China Seas than the Northen Pacific Ocean. To test these findings in a wide-ranging animal, we tracked streaked shearwaters (Calonectris leucomelas) from four islands in Japan using global positioning system (GPS) and measured persistent organic pollutants (POPs) in the oil of their preen glands. The POPs did not change during 6 to 21 days when birds from Awashima were foraging only in the Sea of Japan, while it increased when they crossed to the Pacific through the Tsugaru Strait and foraged along the eastern coast of Hokkaido where industrial cities occur. These results indicate that POPs in the oil reflect relatively short-term exposure. Concentrations of POPs displayed greater variation among regions. Total polychlorinated biphenyls were highest in birds foraging in a small area of the semiclosed Seto Inland Sea surrounded by urbanized coast, p,p′-dichlorodiphenyltrichloroethane (DDT) was highest in birds foraging in the East China Sea, and total hexachlorocyclohexanes were highest in birds foraging in the Sea of Japan. All were lowest in birds foraging in the Pacific. This distribution of POPs concentration partly agrees with previous findings based on mussels, fish, and seawater and possibly reflects the mobility and emission sources of each type of POP. These results highlight the importance of information on the foraging area of highly mobile top predators to make them more effective monitors of regional marine pollution.Keywords:

Water pollution is a universal problem; this vital matter essential to the life of all living things has become rare where drought is the only truth despite rising rates of precipitate compared with recent years. Our study is precisely to support the conformity of effluents discharged in the Bay of Arzew with the standard Algerian and study the impact of organic pollution on surface water, to protect the environment where the final recipient is presented in our case by the sea .This bay is considered as a vulnerable area where the potential disasters can cause great maritime pollution. There are many vulnerable sites, which could cause serious pollution’s problem by oil spills. The bay of Arzew presents probably the most polluted marine environment of the Mediterranean. For this purpose several samples are taken and a range of analysis is performed, such as chemical oxygen demand (COD), biological oxygen demand (BOD), oil content (HC) .The main objective of this work is determining the source of pollution and the more intense process of treating the pollution before being evacuated to the sea.

Checking and monitoring water quality pollution is an important thing to do. In general, tourist areas are more susceptible to water pollution. The Peukan Bada subdistrict area has Ujung Pancu beach with a length of ± 2 km and is a marine area that plays an important role for the surrounding community. The development of human activities that occur around coastal areas will have an impact on water pollution. The aim of this research is to determine the level of pollution that occurs in the waters of Ujung Pancu Beach using the Pollution Index method based on physicochemical measurements. Water quality values are measured based on water quality standards for marine tourism purposes in the Minister of Environment Decree No. 22 of 2021. Based on the results of the analysis carried out, the result was that the level of pollution obtained was moderate pollution. The average value obtained at high tide is around 8.09 and at low tide around 8.47. Overall, the water quality parameters of Ujung Pancu beach need to be considered so that they are maintained so that they do not have a negative impact on tourist visits and marine tourism activities.

The environment condition of rural area in Wuyang County,Henan Province was investigated by questionnaire.The results showed that,non-point pollution and point pollution are coexistence,industrial pollution and living pollution,new pollution and old pollution are interlaced,degradation of ecological resources become serious gradually.According to the investigation results,rural environmental protection autonomy system should be promoted.

ABSTRACT During the past five years, the Soviet Union has made particular efforts to develop regulations and procedures for the prevention and cleanup of pollution of the marine environment from shipping. This paper briefly discusses the governmental organization relative to environmental regulation and enforcement, and marine pollution response practice and equipment. The information presented was obtained through a Joint U.S.-U.S.S.R. Project on Prevention and Cleanup of Pollution of the Marine Environment from Shipping, the first meeting of which took place in May 1973.

The oil pollution caused by ship transport mainly includes two categories the first is the pollution caused by normal navigation, eg: cabin bilge water, oil tanker ballast water, washing water and so on. The second category is due to shipping accidents, eg: oil spill. Among all types of marine pollution, oil pollution should be said that the most serious. Because oil is difficult to volatile, making the oil on the sea to form a terrible oil film, resulting in a series of serious consequences. Oil as the basis of industry, it can’t be replaced for industry, the oil bring us a lot of convenience in production and life, but also brought the significant pollution to the environment, especially the marine environment, and now, oil Pollution has become one of the most important causes of marine pollution
