#玫瑰盐在我国仅限工业用途#【[话筒]转发提醒！#部分玫瑰盐检出多种重金属#】近年来，一种号 称"纯天然无污染、富含矿物质"的粉红色"玫瑰盐"走红网络，成为不少消费者眼中的"高端食盐"。然 而，近日有网络平台视频显示，测评的5款玫瑰盐，检测出了铅、砷、铬等重金属。"玫瑰盐"又称"喜马 拉雅盐"，因含有铁、镁等矿物质而呈现粉红色。记者注意到，多地市场监管部门曾发文提醒，在我 国，"玫瑰盐"仅限工业用途，不符合食用盐食品安全标准，不得作为食用盐流通使用。专家表示，根据 我国相关标准，食用盐需满足"色白、味咸、无异味"等条件，"玫瑰盐"单就"色度"一项就不符合我国标 准。此外，"玫瑰盐"作为天然岩盐，若未经严格提纯，可能含铅、砷、铬等，存在潜在的重金属污染。 对于绝大多数人而言，经济、安全的普通食盐就能满足日常需求。 转自：北京头条 ...

Core Viewpoint - The article discusses the decline in blood lead levels among children in China and emphasizes the importance of screening, detection, and treatment methods for lead and other heavy metal pollution, as well as preventive measures for institutions and individuals [1][4]. Summary by Sections Blood Lead Levels and Health Impact - Normal blood lead levels in humans are generally below 50μg/L. Lead enters the body primarily through the digestive system (70%-80%), followed by inhalation and skin contact. Accumulation in the brain can lead to irreversible cognitive decline in children [2]. Treatment and Detection - Lead removal typically occurs through gastrointestinal excretion, and some patients may require chelating agents to expedite this process. Even after treatment, lead stored in bones can gradually re-enter the bloodstream [3][4]. Screening Guidelines - The 2006 "Guidelines for the Prevention of High Lead Levels and Lead Poisoning in Children" indicates that most children have low blood lead levels, thus universal screening is unnecessary, except in areas with industrial lead pollution [4][5]. Monitoring and Emergency Response - Institutions should conduct soil checks in agricultural areas and ensure compliance with safety standards in schools. Environmental monitoring by local authorities is crucial to detect significant fluctuations in heavy metal levels [7][8]. Individual Prevention Measures - Individuals, especially those at high risk, should maintain personal hygiene, ensure food safety, and use safe materials for children's utensils. Regular monitoring is advised for those potentially exposed to lead [9][10].

Core Viewpoint - The article discusses the trends and preventive measures regarding lead and heavy metal poisoning, particularly focusing on children's health and the effectiveness of existing guidelines and monitoring systems in China [2][5]. Group 1: Trends in Heavy Metal Poisoning - Over the past decade, heavy metal poisoning incidents globally have primarily resulted from environmental pollution (soil, water, air) and resource recovery pollution (e.g., batteries) [1][5]. - In China, children's blood lead levels have generally shown a downward trend, especially since the ban on leaded gasoline in 2000, leading to better control of lead in soil, water, and air [2][5]. Group 2: Diagnosis and Treatment - Normal blood lead levels in humans are generally below 50 μg/L, with lead entering the body primarily through the digestive tract (70%-80%), respiratory tract, and skin [2][3]. - The treatment for lead poisoning typically involves gastrointestinal excretion, and in cases of high blood lead levels, chelating agents may be used to expedite this process [3][4]. - The guidelines from the National Health Department indicate that routine screening for lead poisoning in children is unnecessary, except in areas suspected of industrial lead pollution [3][4]. Group 3: Monitoring and Prevention - Institutions should conduct regular monitoring of agricultural soil for heavy metal contamination before use, and educational facilities must adhere to safety standards in materials used for construction and equipment [6][7]. - Public health prevention efforts should focus on controlling pollution sources and ensuring thorough investigations of any poisoning incidents to identify the source of contamination [5][6]. - Individuals, especially those at higher risk, should maintain personal hygiene, ensure food safety, and use safe materials for children's dining and drinking [6][7].
