However, she adds, "We were surprised to see that some of the workers who were exposed to dispersants and did not report having symptoms while they were working on the cleanup reported having them when they enrolled in the study." Sandler explains that people may be better at reporting how they feel in the moment than recalling how they felt in the past, but it is also possible that the association between dispersant exposure and current symptoms is due in part to people overreporting their symptoms.
However, although DAC is rarely used as a dispersant agent, an investigation found that the carboxylic group-containing agent is a good dispersant for deflocculated alumina suspensions [11], and when a metal oxide is dispersed in water, the pH condition of the dispersant agent should be adjusted (pH < pH isoelectric point - 2 or pH > pH isoelectric point+ 2) [12] as YSZ has an isoelectric point at pH 6-8 [13, 14].
