【摘要】:正據(jù)外媒報(bào)道,研究發(fā)現(xiàn)雨后沿海水域諾如病毒、致病菌含量較高,人體受感染的風(fēng)險(xiǎn)加大。這項(xiàng)研究分析了654名沖浪者兩年間的健康數(shù)據(jù)。根據(jù)這項(xiàng)研究,加利福尼亞州的沖浪者受感染,主要是諾如病毒引起的腹瀉嘔吐。專家分析稱,諾如病毒是典型的未經(jīng)處理的污水污染造成的。大雨經(jīng)常導(dǎo)致污水處理廠超載,污水處理廠將未經(jīng)處理的廢水排入附近的河流或海中,對(duì)水中運(yùn)動(dòng)者構(gòu)成健康風(fēng)險(xiǎn)。研究發(fā)現(xiàn),大雨后三天內(nèi)去海中沖浪者平均1000人有30人生病。相比之下這些日子
[Abstract]:According to foreign media reports, the study found that the coastal waters after the rain Norovirus, high levels of pathogenic bacteria, increased risk of human infection. The study analysed health data from 654 surfers over two years. According to the study, surfers in California are infected, mainly from diarrhea and vomiting caused by Norovirus. Experts say Norovirus is caused by typical untreated sewage contamination. Heavy rains often lead to overloading of sewage treatment plants, which drain untreated wastewater into nearby rivers or seas, posing a health risk to water sports. The study found that an average of 1000 surfers fell ill in three days after heavy rain. Compared with these days,
