A | During a training exercise in the ocean on Sunday, a lifeguard from Long Island, who was playing a victim, was attacked by a shark, the local media reported.,The lifeguard reportedly fought the animal off with his bare hands. During his scary encounter with the 4- to 5-foot-long (1.2-1.5 m) shark, Smith Point Beach lifeguard Zack Gallo was bit in the chest and right hand, Suffolk County Executive Steve Bellone reportedly stated at a news conference.,"He was playing the role of a victim, and in the midst of that, actually became a victim when this shark bite occurred,” the official noted.,Bellone reportedly claimed that Gallo defeated the shark by "punching down" on it. According to the report, the lifeguard's hand injuries "occurred as he was beating off the shark," and after that interaction ended.",The lifeguard reportedly was "bleeding significantly" when other guards who were already in the water for the exercise raced to aid him, but the victim surprisingly managed to get out of the water unaided.,After being bandaged, the injured lifeguard was brought to a nearby hospital.,“Fortunately, he is doing well,’’ the official said. “He’s in very good spirits at Southside Hospital … getting some stitches.",The attack caused the beach to be closed. Later, the same shark may have been spotted by police using a drone to monitor the ocean, according to the report, but the authorities could not determine if it was the same shark or not.,Even more to the news about sharks getting dangerously close is that Cupsogue, a second beach east of Smith Point, was also reportedly closed on Sunday "due to dangerous marine activity.",On July 1, a 57-year-old swimmer in the area of Jones Beach in Nassau County experienced a "possible shark bite," the police said. This incident prompted the authorities to increase beach patrols ahead of Fourth of July.,Shark attacks on Long Island are "very rare," but recently they have reportedly become more frequent. More shark sightings have occurred in the last two years than in the prior ten years combined.,Two Women Killed in Shark Attack Off Egypt's Red Sea CoastYesterday, 13:00 GMT。
B | 讯 8月13日，国务院新闻办公室举行“开局起步‘十五五’”系列主题新闻发布会。
C | 生态环境部副部长、国家核安全局局长董保同在会上介绍，“十五五”时期，生态环境部将进一步聚焦监测和执法两个生态环境监管重要领域，更大力度推进数智化转型，大幅提升监管质效。 生态环境监测方面。
D | “十四五”时期，监测数智化转型取得了实质进展，主要是降本增效防风险。现在确定的“十五五”工作目标，就是到2030年，国家生态环境监测网重点业务领域人工参与度下降70%、效率提升5倍以上。具体说，就是在大气、水等重点领域全面实施数智化升级工程，推进国控站点仪器设备的智能化更新改造。比如在大气方面，将加大人工智能预测模型应用，升级空气质量预报平台，到2030年，全国72小时PM2.5超标天预报准确率提高到80%以上。在水方面，将新建一批自动采样站，组建海洋无人船编队，改变现有人工监测为主的模式。
E | 在固废、新污染物等新兴领域，将加快新技术、新模式的应用。比如在固废方面，将利用米级、亚米级卫星开展常态化遥感监测，精准锁定固废违法堆放点位。
F | 在新污染物方面，依靠现有地表水、海洋监测站点，同步采样送样，以较低成本实现多介质、多指标监测的协同增效。 环境执法方面。将应对生态环境执法面临的新挑战，构建从问题发现、预警到处置的全流程智慧执法体系，把污染源自动监控数据，包括卫星遥感数据、热点网络信息等整合，利用人工智能和大数据分析，精准发现问题线索，大幅度减少低效率的现场检查。同时，搭建智慧执法指挥平台，系统整合现有污染源分布、执法力量、环境质量，还有一些共享数据与线索处置信息，支撑跨区域、跨部门、跨领域执法。通过数智赋能，推动执法由“粗放监管”向“精准治理”、从“被动应付”向“主动防控”转变，提高执法准确性，有效缓解基层执法人员不足的矛盾，同时减少对企业的干扰和负担。版权申明：凡注有“”或电头为“”的稿件，均为独家版权所有，未经许可不得转载或镜像；授权转载必须注明来源为“”，并保留“”的电头。 。
