Abstract

Ubiquitous Computing means network connectivity everywhere, linking devices and systems as tiny as adrawing pin and as large as a worldwide product distribution chain. This paper explores issues arising withimplementing Ubiquitous computing, and gives examples of success stories where researchers leveragedUbiquitous computing effectively. The paper further enumerates certain key issues and factors that affectthe implementation of Ubiquitous computing, and finally provides insights towards how to seamlesslyachieve the adoption of this new era approach to computing.

Abstract

The use of pesticides in agriculture can lead to the accumulation of residues in food commodities, posing potential health risks. The levels of organochlorine pesticide residues in selected vegetables (sorrel, spinach, okra, lettuce and sesame) consumed in Yola, Adamawa State, Nigeria were assessed. Vegetable samples were collected, extracted using the QuEChERS method and analysed by gas chromatography-mass spectrometry (GC-MS). Health risk assessment was conducted by estimating the estimated daily intake (EDI), hazard quotient (HQ), hazard index (HI) and lifetime cancer risk (LCR). Organochlorine pesticides, including lindane, aldrin, endosulfan and DDT, were detected in varying concentrations across vegetable samples. Spinach exhibited the highest levels, exceeding European Union Maximum Residue Levels for α-lindane (1.555 mg/kg), β-lindane (1.718 mg/kg), δ-lindane (1.556 mg/kg), aldrin (1.990 mg/kg), endosulfan I (1.960 mg/kg) and endosulfan II (5.209 mg/kg). The HI was 5.56, indicating potential non-carcinogenic health risks. Spinach posed a high cancer risk for α-lindane, β-lindane and p,p'-DDT. Organochlorine pesticide residues in vegetables consumed in Yola exceeded regulatory limits, with spinach posing the highest health risks. Effective monitoring, sustainable agricultural practices and strengthened regulatory frameworks are crucial to safeguard food safety and public health. Thus, consumption of vegetables in Yola should be done with caution.
