… period on crop farms when only commercial fertilizers are being used.The concentrations of Hg and Pb tend to increase in the topsoil on crop farms with more than 3 % forHg and with 2 % for Pb in 100 years. There is today balance between supply and removal of the traceelements …
… of theoretical leakage data from Kd-values were made. Surface water concentrations were also compared with levels of metals in sediments to see whether any connection existed between them. Additional mass balances were calculated to take suspended solids in the surface water …
… substances, screening trialswere performed with the CTMP waste water. The concentration of surface-active substances was estimated bymeasuring the surface tension of the waste water. The surface tension sinks with increasing concentration of thesesubstances. 250 ml …
