狭义的木材工业或木材加工工业(不包括造纸、纸浆工业)的公害问题,被公害大的造纸、纸浆工业所掩盖着,人们关心甚少。即使将公害局限于水质污染方面,近来认为水的自然净化能力正在接近其界限。那怕从狭义的木材工业所排出的废水数量小得不能与造纸、纸浆工业的废水相比较,也不能够说从木材工业排出的污染物质的负荷对水质就没有大的影响了。关于与木材工业有关的水质污染问题,
There is little public concern about the problem of pollution in the narrow wood industry or in the wood processing industry (excluding the papermaking and pulp industries) that is overshadowed by the paper-making and pulp industries with large pollution levels. Even if pollution is limited to water pollution, it has recently been assumed that the natural purification capacity of water is approaching its limits. Even if the quantity of waste water discharged from the narrow wood industry is too small to be compared with that of the paper industry or the pulp industry, it can not be said that the load of pollutants discharged from the wood industry has no significant impact on the quality of water. Regarding the water pollution related to the wood industry,
