Rain samples were collected from Warri and Port Harcourt, two major oil-producing cities of Nigeria in April-June, July-August, and September-October 2005 and 2006. Awka, a "non-oil" city was used as control. Samples were collected from three points, using clean plastic basins fastened to a table, 2 m above ground level and 115 m away from tall buildings and trees. Water samples were filtered and acidity determined using digital pH meter. The results show that the rain samples were acidic. The pH values for the 2 years under study show that the rainfall in Warri was more acidic than that of Port Harcourt. Oil exploration and other anthropogenic sources may be responsible for the acid rain in the Niger Delta region of Nigeria.
2005年和2006年的4月至6月、7月至8月以及9月至10月期间，从尼日利亚两个主要产油城市瓦里和哈科特港采集了雨水样本。以“非产油”城市阿库作为对照。样本从三个点采集，使用固定在离地2米高的桌子上的干净塑料盆，且距离高楼和树木115米远。对水样进行过滤，并使用数字pH计测定酸度。结果表明，雨水样本呈酸性。所研究的这两年的pH值表明，瓦里的降雨比哈科特港的降雨酸性更强。石油勘探和其他人为来源可能是尼日利亚尼日尔三角洲地区酸雨的成因。
