kiintoaineksen

Kiintoaineksen is a Finnish term that translates to "solid matter" or "suspended solids" in English. It refers to any particulate matter that is dispersed within a fluid, typically water or air. In environmental science and engineering, kiintoaineksen is a crucial parameter for assessing water quality. High levels of suspended solids can reduce light penetration in water bodies, affecting aquatic plant life and the visibility for organisms that rely on sight. It can also clog the gills of fish and smother benthic habitats.

The presence of kiintoaineksen can originate from various sources. Natural sources include soil erosion, volcanic ash, and organic debris from decaying plant and animal matter. Anthropogenic sources are often significant and include sediment runoff from construction sites, agricultural fields, and unpaved roads. Industrial discharges, sewage treatment plant effluent, and dredging operations can also contribute substantial amounts of suspended solids to waterways.

Measuring kiintoaineksen is usually done by filtering a known volume of water through a pre-weighed filter and then drying and weighing the retained solid matter. The result is typically expressed in milligrams per liter (mg/L). Understanding the concentration and composition of kiintoaineksen is vital for managing water resources, designing wastewater treatment systems, and monitoring the impact of human activities on aquatic ecosystems.
