All this comes as China grapples with a mounting water shortage. Across the country, millions of tons of raw sewage, industrial waste and fertilizer runoff have turned lakes into algae-covered cesspools. According to official statistics, more than half of China''s major waterways are so polluted that fish are dying or water is unsafe for drinking or irrigation. More than 300 million people -- almost one-quarter of the population -- lack access to clean drinking water, the government says.

所有这些问题都是在中国水资源日益短缺的大背景下出现的在全国许多地方,大量未经处理的污水、工业废水以及含有化肥残留的农田用水把众多湖泊变成了污水池,大片水面被藻类所覆盖从官方的统计数字看,中国一半以上主要河流的污染程度已经严重到了鱼虾绝迹或河水已无法供饮用和灌溉之用的程度

Alkylbenzene, normal alkanes and alkylcyclohexane on the pyrolysates of P. Boryanum at 300℃ had uniform distribution and the relative content of them was similar, indicating that they originated from same precursors. Fatty acids, alcohol and ketone in algal cell are the possible precursors. For example, the precursor of relatively abundant C〓 alkylbenzene and alkylbenzene with C〓 side chain perhaps related with palmitic acid. N-alkylnaphthalene in pyrolysates at 300℃ probably derived from alkylation of cleavage products of aromatic steranes and terpanes.
