在雨季和旱季，在河边和附近的一口井中进行了一项研究，以评估烟草废物处理对路边的影响。尼古丁浓度存在显着的季节性变化，旱季高于雨季（p<0.05）。然而，无论季节如何，在垃圾场附近观察到的尼古丁含量最高，而在上游和井水中没有或仅获得微量尼古丁。磷酸盐、硫酸盐和浊度浓度存在季节差异，旱季高于雨季（p<0.05）。然而，硫酸盐浓度的季节变化趋势与磷酸盐相反，雨季高于旱季。在雨季，各采样点的浓度变化显着（p<0.05），靠近垃圾场的点最高，其次是上游，下游最低。当局必须执行受控烟草废物处置的立法，以避免对环境造成有害影响。
A study was carried out in a strip of a river and in a nearby well in the rainy and dry seasons to assess the impact of tobacco waste disposal on the roadsides. There were significant seasonal variations in the concentration of nicotine being higher (p<0.05) in the dry season than in the wet season. Regardless of season however, nicotine was observed in highest amounts close to the dumpsite and none or just trace amounts were obtained upstream and in the well water. There were seasonal differences in the concentration of phosphate, sulphate and turbidity, being higher (p<0.05) in the dry season than in the rainy season. However, the concentration of sulphate followed an opposite seasonal trend to that of phosphate, being higher in the rainy season than in the dry season. In the rainy season, the concentrations varied significantly (p<0.05) across the sample points, being highest at point close to the dumpsite followed by the value upstream and the least was obtained downstream. The authorities must enforce the legislation of controlled tobacco waste disposal to avoid harmful environment effects.
