우리나라에 해양경찰(이하 해경)이 있다는 것은 많은 사람이 알고 있지만, 해경의 주요업무 중 하나가 해양오염관리라는 사실은 국민 일부만이 알고 있는 것 같다. 선박사고로 발생하는 기름 및 위험유해물질(HNS)의 유출시 오염 방제작업, 태풍 또는 홍수로 발생되는 해안쓰레기 정화활동, 해양배출 폐기물 관리 등 다양한 해양환경 업무를 통하여 국민모두가 해양환경의 중요성을 다시 한번 인식할 수 있는 기회가 되었으면 한다.

The environmental problems caused by food waste have been a steady social issue, and the severity of the problem emerged as the 2013 London Convention banned the marine emissions of waste water. The government implemented measures related to food waste, but prior studies showed that it lacked continuity and lacked strategies for each area of occurrence, and emphasized that citizens' participation is important to implement effective reduction policies. Therefore, this study proposed a food waste disposal machine through user experience analysis as a way to induce civic participation. To this end, the design development direction was outlined in this study after the pre-research and user survey stages through FGI and user journey maps. Based on this, the proposed treatment machine facilitates the frequent discharge of waste and simplifies the process of food waste in the home. In addition, the moment of direct contact between the user and waste is only the point at which the waste is released to the handler, thereby minimizing the negative experience the user has experienced.

선박으로부터 발생하는 해양사고는 귀중한 인명과 재산은 물론 사고 선박으로 부터 배출된 유류와 폐기물 등의 유해물질은 주변어장을 황폐화시킬 뿐만 아니라 해양생물을 멸종시키는 해양오염원이 되고 있다. 해상에서 발생하는 해양사고는 항행중 태풍이나 폭풍 등을 만나 선박이 침몰하거나 전복되는 불가항력적인 자연 재해와 선박의 구조와 설비 등의 선체 결함에 의한 요인도 있으나, 최근의 해양사고는 그 선박을 조종하고 관리하는 승무원의 항해 부주의나 직무태만, 항해정보의 부정확과 운항기술의 미숙등 인적과실에 의해 발생하는 선박해양사고가 대부분을 차지하고 있다.

Due to floating marine debris, seabed litters, dead shellfishes and polluted sediments, etc. , which are mainly caused by fishery activities in a large scale around the coastline, expansion of industrialized areas from economic development and drastic increase of free time by the improved standard of living, Korean coast is believed to be cast beyond the self purification of marine ecosystem. Seabed litters, if not remedied in a timely manner, will eventually lead to the overall disorder of benthic ecosystem. Thus, in order to prevent marine ecosystem from being thrown into confusion by seabed litters and to restore ocean environments, it is reasonable to investigate the current status of the seabed litters by carrying out an extensive examination on them and to equip ourselves for marine debris with an systemized tool that provides supports to the building process of an efficient methodology of litters disposal through managing related data appropriately. As an primary step to this goal, a systematic method of investigation is presented in this paper. With this methodology, the present state of the seabed titters is properly understood for the specified list of ports.

2013년 1월부터 국민의 건강을 보호하고 쾌적한 수질 및 수생태계 환경을 유지하기 위한 환경기준 항목이 추가되며, "어린이용품 환경유해인자 사용제한 등에 관한 규정"의 시행으로 유해 어린이용품의 관리가 강화된다. 또한 자동차의 배출 가스 수시점검을 효율적으로 추진하기 위해 배출가스 원격측정제도가 시행되며, 음식물류 폐기물의 재활용 과정에서 발생되는 음폐수에 대한 해양배출이 전면 금지된다. 2013년부터 달라지거나 새롭게 시행되는 환경행정 내용을 정리하였으니 업무에 참고하시기 바랍니다.

The effect of sediments in a waste dumping area on marine organisms was evaluated using sediment toxicity tests with a benthic amphipod (Monocorophium acherusicum) and bioluminescent bacterium (Vibrio fischeri) in accordance with the Korean Standard Method for Marine Wastes (KSMMW). Nine sites in the East Sea-Byeong, East Sea-Jeong, and Yellow Sea-Byeong areas were sampled from 2016 to 2019. The test results showed that the relative average survival rate (benthic amphipods) and relative luminescence inhibition rate (luminescent bacteria) were below 30%, which were judged to be "non-toxic." However, in the t-test, a total of 12 benthic amphipod samples (6, 1, 1, and 4 in 2016, 2017, 2018, and 2019, respectively) were significantly different (p<0.05) from the control samples. To identify the source of toxicity on benthic amphipods, a simple linear regression analysis was performed between the levels of eight heavy metals (Cr, As, Ni, Cd, Cu, Pb, Zn, and Hg) in sediments and the relative average survival rate. The results indicated that Cr had the highest contribution to the toxicity of benthic amphipods (p = 0.000, R2 = 0.355). In addition, Cr was detected at the highest concentration at the DB-85 station and exceeded the Marine Environment Standards every year. Although the sediments were determined as "not toxic" according to the ecotoxicity criteria of the KSMMW, the results of the statistical significance tests and toxicity identification evaluation indicated that the toxic effect was not acceptable. Therefore, revising the criteria for determining the toxic effect by deriving a reference value through quantitative risk assessment using species sensitivity distribution curves is necessary in the future.

For the remediation and restoration of contaminated sediment at the West Sea-Byeong dumping site, dredged materials was dumped in 2013, 2014, 2016, and 2017. The physicochemical properties and benthic fauna in surface sediments of the capping area (5 stations) and natural recovery area (2 stations) were analyzed annually from 2014 to 2020 to evaluate the capping effect of the dredged materials. The natural recovery area had a finer sediment with a mean particle size of 5.91-7.64 Φ, while the sediment in the capping area consisted of coarse-grained particles with a mean particle size of 1.47-3.01 Φ owing to the capping effect of dredged materials. Considering that the contents of organic matters (COD, TOC, and TN) and heavy metals in the capping area are approximately 50 % lower (p<0.05) than that in the natural recovery area, it is judged that there is a capping effect of dredged materials. As a result of analyzing macrobenthic assemblages, the number of species and ecological indices of the capping area were significantly lower than that of the natural recovery area (p<0.05). The number of species and ecological indices at the capping area were increased for the first four years after the capping in 2013 and 2014 and then tended to decrease thereafter. It is presumed that opportunistic species, which have rapid growth and short lifetime, appeared dominantly during the initial phase of capping, and the additory capping in 2016 and 2017 caused re-disturbance in the habitat environment. In the natural recovery and capping areas, Azti's Marine Biotic Index (AMBI) was evaluated as a fine healthy status because it maintained the level of 2^nd grades (Good), whereas Benthic Pollution Index (BPI) remained at the 1^st and 2^nd grade. Therefore, capping of dredged materials for remediation of contaminated sediment in the dumping site has the effect of reducing the pollution level. However, in terms of the benthic ecosystem, it is recommended that the recovery trend should be monitored long-term. Additionally, it is necessary to introduce an adaptive management strategy when expanding the project to remediate the contaminated sediment at the dumping area in the future.
