代谢
微囊藻毒素极其稳定,能够抵抗在大多数自然水体中发现的常见化学分解,如水解或氧化。这些毒素在高温(40°C或104°F)以及在非常低的(<1)或高的(>9)pH值下会缓慢分解。在pH为1和40°C的条件下,毒素降解一半所需的时间(半衰期)为3周;在典型的环境条件下,半衰期为10周。
Microcystins are extremely stable and resist common chemical breakdown such as hydrolysis or oxidation under conditions found in most natural water bodies. These toxins can break down slowly at high temperature (40 °C or 104 o F ) at either very low (<1) or high (>9) pH. The half-life, the time it takes for one-half of the toxin to degrade, at pH 1 and 40 oC is 3 weeks; at typical ambient conditions half-life is 10 weeks.
