Preliminary Study

Field investigation, trace elements geochemistry, borehole and groundwater data were employed to determine the level of contamination or pollution of heavy and trace elements in abandoned quarrying, agricultural sites and its adjourning communities which are leads and other parts of Boki Local Government Area which have massive basement rocks as prospects for quarry establishment. This preliminary study on geosphere-biosphere becomes useful in medical geology as rock-soil-water-human interactions, and relationships are important and obvious. The mining pits depths range from 30.5 m to 50.0 m, while the boreholes depths is 41.0 m to 45.0 m and the thickness of regolith soil weathered Feralsols soil and less weathered Acrisols soil, varies from  22.0 m to 35.0 m in places. The Geochemical data obtained indicates Ba, Th, Ce, Zn, Zr are high in all rocks while Cr and Ni are generally low. In the water samples, some borehole values for the faecal pollution are high and indicates the water is contaminated, CaCO₃, Mg are high, while NO₂, F are low, when compared with established data from WHO standards, they indicates anomalies. The high Ba contents in a previous laboratory animals study shows it can cause nephropathy, but not carcinogenic or genotoxic. The identified boreholes water that are contaminated should be disinfected before use. For a sustainable quarry development in the area, there should be an Environmental Impact Assessment (EIA) with a clear baseline data, reclamation, remedial and rehabilitation procedures before abandonment at the end of the life of the quarries.

This study assessed the influence of teacher’s characteristics and other related factors in the implementation of Environmental Education curriculum in secondary schools in Cross River State, Nigeria. Two research designs were used, survey inferential and Expost facto research design. The study is located in the department of Environmental Education, University of Calabar, Nigeria. Two research questions converted into two hypotheses were formulated for the study.  A sample of three hundred (300) respondents were selected using the multistage random sampling technique comprising of twenty five (25) lecturers and two hundred and seventy five (275) postgraduate and final year undergraduate students in the department of Environmental Education, University of Calabar. Data was collected using a structured questionnaire, the instrument administration was done by the researchers and same were collected 100%. Pearson Product Moment Correlation Analysis and regression analysis were used to test the hypotheses at 0.05 significance level and 298 and 290 degrees of freedom respectively. The result shows that teacher’s characteristics do significantly influence Environmental Education curriculum implementation in secondary schools. The regression analysis also shows that 6 factors listed impedes the implementation of Environmental Education curriculum, while four were not significant factors influencing Environmental Education curriculum in secondary schools. It was however recommended that teachers with competence in pedagogic knowledge of Environmental Education with classroom management skill should be employed to drive the process, while arrangement should be put in place to make Environmental Education a subject for students to offer and write in final senior secondary school examination among other.
