Abstract The chemical and radiological risks associated with uranium in the well, tap/borehole and river/creek waters within three communities that host Ogoniland oilfields was here assessed and measured with gamma ray spectroscopy. The results obtained were used to evaluate chemical and radiological risk over lifetime ingestion by the inhabitants in the area. The activity concentrations of uranium in the water supply sources were found to range from 2.42±0.45 to 12.77±1.12Bq/l. The uranium mass concentration was found to range from 97.52±18.13 to 514.71±45.14µg/l. These uranium mass concentration values of the three water supply sources was found to be over 5 times higher than the recommended international permissible limits. The radiological risks for cancer mortality and morbidity risks were found to be lower than permissible standard which respectively ranged from 9.08x10 -5 to 4.79x10 -4 and 1.39x10 -4 to 7.34x10 -4 . However, the chemical toxicity which was estimated using lifetime average daily dose (LADD) and hazard quotient (HQ) was found to vary respectively from 2.67 to 14.09µg/kg/day and 4.45 to 23.48. The LADD values exceeded the acceptable reference dose level of 0.6µg/kg/day and the international threshold daily intake value of 1.0µg/kg/day. The HQ was greater than unity implying significant potential risk of uranium in water due to chemical toxicity. Human risk arising from ingestion of uranium in water was therefore attributed to the chemical toxicity of uranium as heavy metal rather than radiological risks. Ion-exchange pre-treatment and reverse osmosis treatment technique should therefore be adopted to the three water supply sources in order to reduce and remove uranium as heavy metal before consumption.

Abstract Background: It has been reported that antioxidant rich spices and vitamins provide protection against oxidative stress in malaria infection. This study examined the antimalarial role of vitamins A and E and aqueous extract of Aframomum sceptrum on oxidative stress caused by the parasite Plasmodium berghei in malaria induced mice. Method: Thirty mice (twenty surviving parasitized mice and ten normal mice) were used for the study. They were divided into 6 groups of 5 mice each as follows: group 1: normal control, group 2: parasitized control, group 3: parasitized mice given 60mg/kg body weight vitamin A, group 4: parasitized mice given 100mg/kg body weight vitamin E, group 5: parasitized mice given 50 mg/kg body weight A. sceptrum extract and group 6: normal+ tween 80. Biochemical analyses determined the blood glutathione (GSH), aspartate aminotransferase (AST), alanine aminotransferase (ALT), albumin and total protein in the serum. Data were analysed using SPSS. Results: The results showed that there were significant (p< 0.05) decreases in blood GSH, albumin total protein and increase in AST and ALT in serum of the parasitized control mice when compared to normal control. Treatment with 100 mg/kg, body weight of vitamin E, 50mg/kg body weight with vitamin A and aqueous extract of A. sceptrum resulted in significant (p< 0.05) increase in blood GSH, albumin, total protein and decrease AST and ALT in serum of the parasitized mice when compared to parasitized control mice. Conclusion: Vitamins A and E might have anti-malaria properties and aqueous extract of A. sceptrum might contain anti-malaria agents that help to reduce some of oxidative stress effects of malaria infection. This study has provided useful context on the global burden of malaria infection and the use of Vitamins E and A. and Aframomum Sceptrum to improve malaria treatment policy.

Abstract The advancement of science has been beneficial to humanity since it has allowed them to get a greater understanding of their environment and the activities they engage in. Additionally, technological improvement and scientific progress have sparked revolutions in a number of industries, including medicine, agriculture, education, information technology, and many others. When considering any kind of advancement in the modern world, science and technology must be taken into consideration. Science fundamentally is the systematic study of the structure and behaviour of the natural and physical world through observations and experiments. Technology (which is basically derived from the Greek work ‘technologia’) is an art, skill, or ability, which is used to create and develop products and acquire knowledge. Scientists used their knowledge to develop technology and then used technology to develop science; so, because of this reason science and technology are an integrated term in today’s world.
