The contaminants affect the soil’s ecological structure and function，leading to decreased soil productivity, lower crop yield（產(chǎn)量），and lower quality of agricultural products-

It also leads to worse water quality in rural areas.

Less than 9 per cent of drinkable water passed checks for bacteria in243 rural water supply stations across the county.

Another survey, which took samples of drinking water and groundwater an 69 small towns。 in Beijing, Tianjin and Hebei Province of North，China, showed that more than half of the water contains too much nitrate（硝酸鹽），which may cause diabetes（糖尿�。゛nd damage the kidney.
