Assessment of occupational exposure to diesel particulate matter through evaluation of 1-nitropyrene and 1-aminopyrene in surface coal miners, India.

DPM (diesel particulate matter) is ubiquitously present in the mining environment and is known for mutagenicity and carcinogenicity to humans. However, its health effects in surface coal mines are not well studied, particularly in India. In this study, DPM exposure and corresponding exposure biomarkers were investigated in four different surface coal mines in Central India.

Environmental prevalence, fate, impacts, and mitigation of microplastics-a critical review on present understanding and future research scope.

Microplastics are considered to be ubiquitous and widespread emerging contaminants. They are persistent in the nature and pose considerable harm to the environment. Their omnipresence is documented in almost all aquatic habitats, several atmospheric and terrestrial environments, and also in human consumables.

Remediation of different nitroaromatic pollutants by a promising agent of Cupriavidus sp. strain a3.

Nitrobenzene, nitrotoluenes and nitrobenzoic acid are toxic and mutagenic. Their removal from the environment is necessary to avoid health and environmental damage. In this study, Cupriavidus strain a3 was found to utilize 2-nitrotoluene (2NT), 3-nitrotoluene (3NT), 4-nitrotoluene (4NT), nitrobenzene (NB) and 2-nitrobenzoic acid (2NBA) as carbon and nitrogen source, resulting in their detoxification.

Adsorption of an emerging contaminant (primidone) onto activated carbon: kinetic, equilibrium, thermodynamic, and optimization studies.

The current study addresses the removal of an emerging environmental contaminant (primidone) in batch adsorption experiments using commercial-grade powdered activated charcoal (PAC). The experiments for the removal of primidone were performed to identify the effect of various adsorption parameters. The second-order rate expression best represented the adsorption kinetics data.

Role of fluoride induced epigenetic alterations in the development of skeletal fluorosis.

Fluoride is an essential trace element required for proper bone and tooth development. Systemic high exposure to fluoride through environmental exposure (drinking water and food) may result in toxicity causing a disorder called fluorosis. In the present study, we investigated the alteration in DNA methylation profile with chronic exposure (30 days) to fluoride (8 mg/l) and its relevance in the development of fluorosis.
