Meteorological conditions and air pollutants are recognised as important for human health, with mortality and morbidity of certain diseases linked to abrupt climate change or air pollutant concentration. Environmental factors have been identified in the literature as risk factors for chronic diseases such as ischemic heart disease. However, there is no likelihood evaluation of disease occurrence probability due to environmental factors. The susceptible group was defined as people aged 51-90 years who were free of ischemic heart disease between 1996 and 2002. A risk information system was built using a Bayesian conditional logistic regression model based on a case-crossover design and applied to data from three databases in Taiwan: air quality variables from the Environmental Protection Administration.

Contamination of soil with potentially toxic elements (PTEs) is gaining attention around the world due to its obvious toxicity and risks to local residents. Soil PTE distribution, source, and environmental risk assessments are thus the first steps toward high-efficiency pollutant degradation and sustainable utilisation. The current study assessed the environmental risk of As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn in Al-Ahsa soils in eastern Saudi Arabia using a variety of contamination indicators and multivariate methods. 30 surface soil samples were collected from palm fields irrigated with groundwater and treated sewage water for analysis. From 1985 to 2021, Landsat images of Al-Ahsa showed an increase in total vegetative area and residential area, but a decrease in bare land area.

The preparation of Iron (III) and Aluminum (III) adsorbents by impregnating two solvents namely, tri-octylamine (TOA) upon Polyurethane foam (PU) and charcoal (C) (charcoal) The relevant factors affecting solvents impregnation process including, solvents concentration, shaking time, volume/mass ratio, impregnation temperature and type of diluents were studied. Also, the adsorption characterization of the prepared adsorbents has studied. The optimum conditions affecting adsorption of Iron (III) and Aluminum (III) at pH of 3, temperature of 25°C for 1h and m/v ratio 10 g/L were the best conditions to remove Iron (III) and Aluminum (III). crude phosphoric acid (WPPA) used as a case study and showed a decrease in Iron and Aluminum from 8500 mg/L and 4234 mg/L to 5117 mg/L and 2012 mg/L.
