Safe Drinking Water Act Latino and African American populations are at higher risk of exposure to drinking water contaminants. Contaminants found in the drinking water of such communities include nitrates, coliform, and lead, which have been linked to cancer, reproductive health problems, gastrointestinal illness, and other health problems. One study found that levels of contaminants in the drinking water of two Nebraska Native American reservations were significantly higher than regional contaminant levels. Another study found that Latino residents in Tucson, Arizona, had higher than average levels of contaminants in their drinking water, which were linked to higher rates of cancer and neurological disorders among
Crop tolerance to seawater obtained half the normal yield per acre, i.e. half of the average yield per acre at national level. The experiment was conducted at Bodega Bay, North of San Francisco, in a laboratory on the Pacific Ocean. A team led by Liu Shiping, a professor of agriculture at Yangzhou University, created rice varieties that can be grown in salt water, and achieve yields of 6,5 to 9,3 tons per hectare. Crop tolerance to seawater Crop tolerance to seawater is the ability of an agricultural crop to withstand the high salinity induced by irrigation with seawater, or a mixture of fresh water
