Abstract

This study was conducted to investigate the effects of spent engine oil and industrial effluent on the soil and Dioscorea bulbifera plant. Spent engine oil (SEO) was added to the buckets filled with 15 kg of loamy soil at different volumes of 0 , 75 , 225, and 375mL. Another bucket was filled with 15 kg of industrial effluent (IE). The results showed that SEO in soil has highly significant (p ≤ 0.05) effects on some of the soil's physicochemical properties. Industrial effluent (IE) had the highest nitrogen content (0.89%) while the lowest was in 75 mL15kg-1 (0.72%). pH was higher in control (4.29) and the lowest was at 375 mL15kg-1 (4.89). The chlorophyll content range was 274.06 mg g-1 (IE) – 349.60 mg g-1 (control). Also, bulbils from IE had the least fresh and dry weight (20.21 g and 14.73 g, respectively). The bioaccumulation factor (BAF) of all heavy metals examined was less than 1, except for copper. Heavy metal uptake order by the bulbil is Cu > Fe > Zn > Pb. Considering the detrimental effects of SEO and IE pollution on soil and plants, it has become necessary for the government to have a policy that will prevent indiscriminate disposal of waste.

废机油和工业废水引起土壤和空气中重金属含量的变化

研究了废机油和工业废水对土壤和黄薯蓣植物的影响。将废机油(SEO)添加到装满15公斤不同体积的壤土的桶中，分别为0,75,225和375mL。另一个桶装满了15公斤工业废水(IE)。结果表明，土壤中的SEO对土壤的部分理化性质有极显著(p≤0.05)的影响。工业废水(IE)含氮量最高(0.89%)，最低为75 ml - 15kg-1(0.72%)。对照pH较高(4.29)，最低为375 mL15kg-1(4.89)。叶绿素含量范围为274.06 mg g-1 (IE) ~ 349.60 mg g-1(对照)。IE的鲜重和干重最少，分别为20.21 g和14.73 g。除铜外，其余重金属的生物积累因子(BAF)均小于1。鳞茎对重金属的吸收顺序为Cu > Fe > Zn > Pb。考虑到SEO和IE污染对土壤和植物的有害影响，政府有必要制定防止随意处置废物的政策。
