Abstract
Saw mill is basic to the manufacture of wood products and is therefore considered very relevant as it is almost impossible to avoid the use of wood or its products in any given household. Although the development of this industry brings great gain, providing employment, sources of livelihood and products which gives comfort, it is yet associated with environmental pollution. The aim of this review is thus to establish the influence of waste generated from the saw mill on the environment and surface water quality in particular, using the Nigerian situation as a case study for other developing nations. Studies have shown that pollution from inappropriate storage and disposal of saw mill waste is not only physical but chemical as well. The manufacture of wood, especially those meant for external use or where they may be subjected to harsh artificial or natural conditions such as weather often requires its treatment with chemicals for preservation. These chemicals may be toxic or possess sufficient capacity to interfere with health or the aquatic biota when exposed. A review of previous studies on the impact of saw mill waste discharges on water quality has shown that surface water qualities especially is compromised when exposed to these waste.
