Oil-Product Pollution of the Kamchatka River

The oil-product pollution of the outlet section of the Kamchatka R. rapidly increased in 2001–2002. Within nine years out of ten in the period from 1992 to 2001, oil products were not found there; however, since 2003, their annual mass transported every year rose above 2.5 thousand t.

The obtained results confirmed the assumption regarding an abrupt growth: the pollution in 1992–2001 was many times less than that in 2002–2021. The transport through the outlet section increased from
