The local refining of crude oil has become a lucrative but disturbing business in the Niger Delta region of Nigeria. Deep inside the forest of the Niger Delta camps are built and used for the local refining of crude oil. The economic benefits this brings to the refiners are clear, however the host communities are severely hit by the activities of the 'local crude oil refiners'. Farmlands have been destroyed and fishing settlements evacuated as a result of pollution of the rivers and estuaries, with loss of lives and properties. This research investigates the impact of the activities of the local refiners on their host communities' farmlands, rivers and estuaries. A quantitative research method was adopted in this study through the administration of questionnaires to local stakeholders (chiefs, the youth, farmers, traders, fishermen/fisherwomen and residents of affected communities). Quantitative data was collected from three communities in the Niger Delta with local refineries and the data was analysed using descriptive and inferential (Chi Square and Correlation) methods. The study demonstrates the high impact of the activities of the refiners on farmlands and fishing areas of the host communities and makes recommendations to all stakeholders in the upstream and downstream sectors of the petroleum industry. In addition, recommendations are made to the Nigerian government, on ways to address the impact of local refining on host communities.

Environmental consequences of petroleum mulch application are crucial in regions prone to wind erosion and desertification. This study aimed to assess the long-term effects of petroleum mulching on soil polycyclic aromatic hydrocarbon (PAH) concentrations and the associated human and ecological risk indices. These indices include incremental lifetime cancer risk (ILCR), hazard index (HI), toxic equivalent concentration (TEQ), toxic unit (TU), and risk quotient (RQ) in soil samples from Khuzestan province, Iran.

Interfacial solar evaporator generation (ISVG) is a new, cost-effective, and eco-friendly emerging method for water desalination. Two main criteria for evaluating ISVG performance are evaporation rate () and solar-to-vapor conversion efficiency (η). The main challenge of the previously presented models for the estimation of and η in 2D systems is that in most cases the calculated values are beyond the theoretical limits, > 1.

(), known for its aromatic leaves and rhizomes, is extensively used in traditional medicine to treat digestive issues, inflammation, pain, anxiety, and stress. The petroleum ether extract of isolates specific bioactive compounds using petroleum ether, a nonpolar solvent effective in dissolving nonpolar plant compounds. This extract potentially offers antimicrobial, anti-inflammatory, and analgesic benefits.
