On average, the SSC in winter is 2 times than that in summer; and the SSC in spring tide is 2.96 times than that in neap tide.(2) The correlation coefficient of the daily tidal range and SSC at a tide circle is 0.86, and it goes up to 0.96 and 0.93 with one day and two days lag of SSC. This reflects that there has a hysteresis of one or two days of SSC to the tidal range.

Then, in 1979, a well-designed study by pediatrician and psychiatrist Herbert Needleman resolved the dispute by establishing a direct correlation between the lead content of a child's teeth and bad classroom behavior. Twelve years later follow-up studies on these children found that those who had the highest lead levels in their teeth as children continued to have school problems through their last year of high school including more school failures, reading disabilities, and lower class standing.
