The La.ga. River in Ma.a.sia.ha. been experiencing a.thropogenic input from urba., rura. a.d industria. a.tivities for ma.y yea.s. Sewa.e conta.ina.ion, possibly origina.ing from the grea.er tha. three million inha.ita.ts of the La.ga. River Ba.in, were exa.ined. Sediment sa.ples from 22 sta.ions （SL01-SL22） a.ong the La.ga.
