Anthropogenic dust pollution influences leaf and root morpho-anatomical traits by altering the metabolism and biochemical properties of indigenous vegetation.

The current investigation analyzed the impact of dust pollution from the stone crushing industry in the Kirana Hills of Sargodha on plant communities, with a focus on seasonal variations in plant metabolism, structure, and heavy metal accumulation at different study sites. The results revealed that heavy metal concentrations were notably higher at extreme dust sites, particularly during the winter season, indicating a significant impact of dust pollution on the environment. Soil analysis revealed distinct compositions across different sites and seasons, highlighting the variability in environmental conditions.

Determination of heavy metals and morphoanatomical characteristics of the monocots Aristida mutabilis and Cenchrus ciliaris in the dust-contaminated stone crushing industry of Sargodha, Pakistan.

The current investigation analyzed the population dynamics of vegetation in the severely dust-polluted environment of the stone crushing industry in the Kirana Hills of Sargodha. Data pertaining to dust levels, soil composition, and vegetation characteristics were systematically collected from all the study sites throughout the year to explore the seasonal fluctuations in the plant community structure and the underlying determinants of these variations. Heavy metal analysis revealed increased concentrations of all heavy metals at the most heavily dust-polluted sites, particularly during the winter season.

Micro-morphological response of some native dicotyledonous species to particulate pollutants emitted from stone crushing activities.

Stone crushing processes release particulates and associated noxious substances in our surroundings that are continuously destructing environmental conditions and ecosystem health. Morpho-anatomical changes in some medicinally important native species (Aerva javanica, Calotropis procera, Digera muricata, Euphorbia prostrata, Euploca strigosa, and Peganum harmala) exposed to heavy dust pollution were evaluated. These species selected on the basis of their ubiquitous distribution in the area.
