We compared rates of reported health symptoms among surfers in urban North Orange County (NOC) and rural Santa Cruz County (SCC), California, during 2 winters (1998 and 1999) to determine whether symptoms were associated with exposure to urban runoff. NOC participants reported almost twice as many symptoms as SCC participants during the 1998 winter. In both study years, risk increased across symptom categories by an average of 10% for each 2.5 hours of weekly water exposure. Our findings suggest that discharging untreated urban runoff onto public beaches can pose health risks.
我们比较了加利福尼亚州北奥兰治县(NOC)市区和圣克鲁斯县(SCC)农村地区冲浪者在两个冬季(1998年和1999年)报告的健康症状发生率,以确定这些症状是否与接触城市径流有关。在1998年冬季,NOC的参与者报告的症状数量几乎是SCC参与者的两倍。在两个研究年份中,每周每接触2.5小时水,各类症状的风险平均增加10%。我们的研究结果表明,将未经处理的城市径流排放到公共海滩上可能会带来健康风险。
