We examined the effects of chlorine on oocyst viability, under the conditions of controlled pH and elevated calcium concentrations required for most community swimming pools. We found that fecal material may alter the Ct values (chlorine concentration in mg/L, multiplied by time in minutes) needed to disinfect swimming pools or other recreational water for Cryptosporidium parvum.
我们在大多数社区游泳池所需的受控pH值和升高的钙浓度条件下,研究了氯对卵囊活力的影响。我们发现,粪便物质可能会改变对游泳池或其他用于隐孢子虫消毒的娱乐用水进行消毒所需的Ct值(氯浓度,单位为mg/L,乘以时间,单位为分钟)。
