天然水是不含酚类化合物的。由于某些工业废水,如石油化工、合成纤维、合成树脂、以及其他化学工业部门排放的污水,会引起酚污染水源。利用这些超标排放的污水灌溉农田,会污染土壤和作物。因此,全国污水灌溉会议提出对酚的污染进行研究。酚有毒性,具有特殊的刺激性气味。经常摄入的酚量超过人体解毒能力时,人就会慢性中毒,发生呕吐、腹泻、食欲不振,头疼头晕、精神不安等症状。因此,研究酚污染水体、土壤以及作物对酚的吸收、转移、分布、累积的规律是很有必要的。
Natural water is free of phenolic compounds. Wastewater from some industrial wastewaters, such as petrochemicals, synthetic fibers, synthetic resins, and other chemical industries, can cause sources of phenol pollution. Irrigation of farmland with these excessive discharge of sewage pollutes the soil and crops. Therefore, the National Sewage Irrigation Conference put forward a study on the pollution of phenol. Phenol is toxic and has a special irritating odor. Frequent intake of phenol exceeds the body’s ability to detoxify, people will be chronic poisoning, vomiting, diarrhea, loss of appetite, headache, dizziness, restlessness and other symptoms. Therefore, it is necessary to study the law of phenolic absorption, transfer, distribution and accumulation in phenol polluted water, soil and crops.
