Abstract
The Ibobo coal mine is an abandoned mine located in the middle belt of Nigeria and lies in the Ajali Formation within the Anambra Basin. The adjoining rivers and streams in this community serve as sources of water for human consumption and plant use. The study was conducted in January 2016 at the peak of the dry season. Major and trace elements were measured in the water samples collected and subjected to the following analysis; conductometry and electro-analytical techniques for physical parameters; titrimetry and spectrophotometry for anions; and flame atomic absorption spectrophotometry for the cations. Further study was carried out to evaluate the cytotoxic effects of the water samples from plants and other living organisms using the root meristems of Allium cepa (onion). This study revealed that the average concentrations of Iron (0.344mg/L), Lead (0.024 mg/L) and Cadmium (0.004 mg/L) are higher than the maximum permissible limits of Standard Organisation of Nigeria (SON) and World Health Organisation (WHO) guidelines for domestic and drinking water qualities. Water from the streams should, therefore, be discouraged for both domestic and agricultural purposes through public health awareness program.

Highlights
The role of water in living things is significant
3.1 Temperature and pH of Water The temperature of the water samples collected at the time of collection is on an average of 30.68oc, while the PH values of the water samples around the mine exhibited an average acidity value of 5.66
Electrical Conductivity (EC) and Total Dissolved Solids (TDS) Lowest electrical conductivity (EC) and total dissolved solids (TDS) values of 0.00μs/cm and 8mg/L respectively were recorded at Ibobo stream-1 while Ukpolo upstream indicates the highest values at 0.33 μs/cm and 237mg/L respectively (Table 1)
Summary
The role of water in living things is significant. It cuts across all sphere of living things such as human consumption, as well as plant and animal life. The Ibobo community which is the focal locality of the study area is located on longitude 7o 57ʹ 22.53ʺ E and latitude 7o 33ʹ 6.75ʺ N. It is situated within Mamu Formation of Anambra sedimentary basin in Central Nigeria This study aims at evaluating the physicochemical parameters of surface water around the abandoned coal mine and examining its effects on plants genetic system using Allium cepa as the test organism
