有不少笙的演奏者和初学者,常常担心笙内的铜制簧片和笙斗中的绿锈有毒,对人体有害,而不能安心地学习吹奏。为此,我求教了理化方面的专家并查阅了有关资料,所得的结论是:这种顾虑是多余的。铜制品表面形成的绿锈,在化学中称为“碱式碳酸铜”。据有关文献介绍,科学家们曾对各种各样的铜化合物作了科学实验,证明铜的毒性与其他金属相此,是非常微弱的。具体到笙来说,笙咀上的气道是向下倾斜的,积水存于笙斗内,一般不会进入口中。即使偶而进入体内,因铜锈不能在水中溶解,也会被排除体外,而不会引起中毒。过去的许多民间吹笙艺人,年过七旬,
There are many Sheng performers and beginners, often worried about Sheng within the copper reed and Sheng Bu in the green rust toxic, harmful to the human body, but can not feel comfortable learning to play. For this reason, I consulted with experts in the field of physics and chemistry and consulted the relevant data. The conclusion I have reached is: This kind of concern is superfluous. The rust formed on the surface of copper products is called “basic copper carbonate” in chemistry. According to the literature, scientists have conducted scientific experiments on a wide range of copper compounds, demonstrating that copper toxicity is very weak compared to other metals. Specific to the Sheng, Sheng Tsui airway is downward sloping, water is stored in the Sheng bucket, the general will not enter the mouth. Even occasionally into the body, due to copper rust can not be dissolved in water, will be ruled out in vitro, and will not cause poisoning. In the past many folk blowing artists, over seventy years,
