<prompt> All the following assess the water-quality-criteria for water pollution are all EXCEPT:Solid particlesDissolved oxygenDissolved chlorideDissolved nitrogen  <response>: Dissolved nitrogen: Ref: 629-30-Park 20thCHEMICAL CRITERIA FOR WATER - QUALITYa Nitrites - should be zero in potable waters, their presence indicates pollution of RECENT origins.b Nitrates - There presence indicates one OLD contamination, Nitrates in water should not exceed 1 mgLc DISSOLVED OXYGEN - This should not be less than 5 mgLd Free and saline ammonia - This is an excellent indicator of sewage contamination of RECENT origin.Free and saline aminonia should not exceed 0.05 mgL in drinking watere Chloride - The standard prescribed for chloride is 200 mgL, The maximum level is 600 mgLf Hardness - The total hardness should not exceed 0.1 mgLg Albuminoid ammonia - In potable water should not exceed 0.1 mgLh Oxygen absorbed - The oxygen absorbed at 37degC in 3 hours should not be more than 1 mgL Water with concentration of total dissolved solids below 1000 mglitre is usually acceptable to the consumers 1200 mgL unpalatable
