The increasing use of electronic cigarettes has raised concerns regarding the potential environmental impact of e-cigarette refill liquids and their release into aquatic ecosystems. Despite their growing consumption worldwide, information concerning their ecotoxicological effects on aquatic vertebrates remains limited. In the present study, the acute toxicity of an electronic cigarette refill liquid was evaluated using different aquatic vertebrate models, including fish eggs ( Danio rer...

This review article summarizes and analyzes modern approaches to the ex-tractive spectrophotometric determination of copper(II) ions in natural wa-ters, ores, environmental, and industrial samples. The quantitative determi-nation of Cu(II) ions is of great importance for scientific and medical re-search, as well as for environmental monitoring. In recent years, numerous methods have been developed to ensure high accuracy, rapid analysis, and high sensitivity in their determination. Particular at...

Methylmercury (MeHg) is an extremely dangerous and toxic organometallic compound that has been found to be persistent and recurrent in various compositions of the environment and is highly suspected to cause dangerous problems in ecosystems and public health owing to the accumulative and magnifying effects that it may cause in the food chain. Soil, one of the essential components for both the storage and partial release of MeHg, is a critical medium through which this compound moves within the e...

The hydroxyapatite crystallization method (HAP) was employed as a phosphorus recovery technology to investigate the effects of different calcium sources on phosphorus removal and recovery from phosphorus-containing wastewater. The results indicate that when CaCl2 was used as the sole calcium source, NaOH was required to be added during the reaction to maintain an alkaline environment, resulting in a PO43--P removal efficiency exceeding 80%. When CaO was used as the sole calcium source, PO43--P r...

Waste is usually produced from man’s activities and Nigeria is ranked among the top producers of waste globally, which is mostly from food and agriculture. This study evaluates the suitability of several agricultural wastes (sugarcane bagasse, coconut husk, groundnut shell, sawdust, palm kernel shell and corncobs) a composite blend (equal weight fraction of sugarcane bagasse, coconut husk, groundnut shell, sawdust, palm kernel shell and corncobs agricultural waste biomass were blended), and conv...

This study was undertaken to assess the ecological and human health risk assessment of soil samples from the vicinity of dumpsites in residential and selected Industrial layouts in Benue State. The physicochemical parameters of the samples, namely, pH, electrical conductivity, , , hardness, and particle size for soil samples were investigated. Heavy metal concentrations were analyzed using AAS. SEM images of industrial waste soils show a regular assemblage of particles. The XRD resul...

This study quantified the activity concentrations of natural radionuclides 238U, 232Th, and 40K in soils from the Lumoru Dumpsite, Bungoma County, Kenya, using a NaI (Tl) gamma spectrometer. The mean concentrations were 7 ± 0.4 Bq/kg for 238U, 57 ± 2.0 Bq/kg for 232Th, and 25 ± 1.3 Bq/kg for 40K. From these values, the absorbed dose rate was estimated at 39 ± 3.4 nGy/h, the outdoor annual effective dose equivalent at 0.09 ± 0.01 m...

The environmental concerns about microplastics are growing among scientists, policymakers, and the public. Plastic particles smaller than 5 mm are known as microplastics, and they come from a variety of primary sources, including personal care products and industrial abrasives. Additionally, they come from secondary sources like the degradation of larger plastics. A growing number of these particles have been found in soil, aquatic systems, and even atmospheric samples, highlighting the urgent n...

A growing concern among the global population is the presence of Micro-plastics (MPs) and Nanoplastics (NPs) within various environmental compartments due to their pervasive, persistent presence. Through atmospheric, aquatic, terrestrial, and biological pathways, these particles enter and traverse ecosystems as a result of fragmentation of larger plastics and primary sources such as industrial abrasives and cosmetics. Since they are widely distributed, their presence in soil, freshwater, marine ...
