Red tides increase off China coast 中国沿海赤潮增多

The number of red tides increasing

赤潮光临次数增多 

Untreated sewage being pumped into the sea off the east coast of China is causing potentially dangerous red tides in the waters around Shanghai.

The local branch of the state oceanography bureau says the number of red tides being reported each year is increasing.

It blames the dumping of untreated household sewage.

The Shanghai Daily newspaper said the local government was monitoring the situation and is expected to spend more on sewage disposal facilities in the next few years. Red tides, a bloom of bacteria that gives a red tint to coastal waters, produces toxins that kill fish and contaminate crustaceans.

由于未经处理的污水被注入中国东部沿海，上海周围水域不断出现存在潜在危险的赤潮。

上海市海洋局说每年赤潮的次数都在增加。

它对未经处理的家庭污水流入大海提出了谴责。

上海日报说地方政府正在监控这一形势，有望近几年在污水处理设施上追加投资。赤潮是由一些细菌引起的，它们快速繁殖，将沿海水域染成红色，同时产生杀死鱼类和污染甲壳类生物的毒素。
