Snowmelt is known to cause peak concentrations of pollutants, which may adversely affect receiving water quality. High concentrations of metals and suspended solids in snow have been reported, whereas studies on organic pollutants are rare. This study aims at investigating the occurrence of anthropogenic organic compounds in urban snow in Gothenburg (Sweden). The most frequently detected organi...

BACKGROUND Access to potable water is grossly inadequate in Douala-Cameroon. The situation is worse in slum areas, compelling inhabitants to obtain water from sources of doubtful quality. This has contributed to frequent outbreaks of water-borne diseases particularly cholera, which results in severe morbidity and mortality. Shallow wells are a major source of water in these areas. We analyzed t...

to investigate the effects of regulated deficit irrigation (rdi) on the growth, yield and quality of ‘yali’ pears, field experiments for c (fully watered control), ew [early withholding of irrigation, water stress from pullulation to 25 days after flower bloom (dafb)], mw (mid-growth withholding of irrigation, water stress from 25 dafb to 80 dafb), and lw (late withholding of irrigation, water ...
