游客捡盐块带回家留作纪念？盐湖景区回应：不建议！

近日，一名网友发帖称自己从青海察尔汗盐湖景区捡拾盐块带回家留作纪念，有人称盐块存在放射性，引发关注。

A recent social media post showing a tourist collecting salt crystals from Qarhan Salt Lake in Qinghai province as a souvenir has triggered public alarm after some users raised the possibility of radioactivity. The scenic area has since responded, urging visitors not to remove the salt — not because of radiation, but due to health risks and environmental pressure.

8月2日，察尔汗盐湖景区工作人员称确有部分游客捡拾小盐块，但景区不建议游客携带，日后恐会出现误食情况。“没有提纯过的盐块，里面可能会有轻微的毒素。”

Staff at the Qarhan Salt Lake site confirmed on Sunday that while picking up small salt pieces is not uncommon, the practice is strongly discouraged. "Unrefined salt may contain trace toxins," a representative said, adding that accidental ingestion remains a real concern.

2日，记者咨询海西州文旅部门，工作人员称对能否捡拾等具体要求暂不清楚，但同样不建议游客捡拾。“景区内的盐存在矿物质，可能会超标，不能直接吃需要加工。”工作人员还指出，景区内的盐生长较为缓慢，现在景区客流量大，如果每个人都装一点，景区恐怕吃不消。

Local cultural and tourism authorities echoed the warning, noting that the salt's mineral content can exceed safe levels for direct consumption and must undergo industrial processing before it is fit to eat. Beyond health hazards, officials pointed to sustainability: the salt forms slowly over time, and with the site drawing large crowds, even small amounts taken by each visitor could accumulate into a significant loss for the landscape.

盐湖游玩指南

天然“盐湖盐”看似洁白，但与市面上所售的达到国家食盐食用标准的精制“湖盐”并不相同，不能直接食用。

湖盐的提炼过程主要分为两个步骤：湖水晒盐和精制盐。

• 湖水晒盐是指将盐湖中的盐水引入盐田，经过太阳的照射和水的蒸发，使湖水中的盐分浓度逐渐增加，形成结晶的盐。游客带走的天然“盐湖盐”就是这种盐，又叫做粗盐，含有一定的杂质和水分，有些杂质可能对身体有害（比如磷酸盐等有害化学物质，贸然食用将会对人体造成不可逆转的伤害），还需要进一步精制。

• 精制盐是指将粗盐进行洗涤、干燥、碾磨、筛分等工艺，去除杂质和水分，提高盐的纯度和质量，使之符合食用标准。这种盐叫做细盐，是我们常见的食用盐。

Although the natural salt crystals appear clean and white, they are not the same as commercial table salt. The crude salt collected by tourists contains impurities and potentially harmful compounds — such as phosphates — that require refining (washing, drying, and sieving) to meet national food‑grade standards.
