Testing key tenets of pyro-ecophysiology: Indicators of drought response in relation to shoot flammability.

Premise: Relationships between flammability and drought tolerance influence vegetation dynamics during fires. A goal of the emerging subdiscipline of pyro-ecophysiology is to identify ecophysiological traits that determine live fuel flammability, but empirical studies of these relationships are rare. Furthermore, drought tolerance has been suggested as a surrogate for low flammability when choosing species to plant near houses in fire-prone areas, but this hypothesis has not been tested.

Archival indicator of metal pollution in a tropical monsoon coastal region: Impact on environment and human health.

Ample sediment and bivalves from six distinct sites along Bangladesh's southern coast were employed to assess the pervasiveness of heavy metal contamination and probabilistic human health implications. For the first time, the extent and spatial distributions of seven metals (Fe, Zn, Pb, Cr, Ni, Mg, and Cd) were determined, together with the associated risk to human and ecological health, from sediment deposition stations and bivalve dwelling sites along the coast. Fe (680.

Unmasking heavy metal contamination: Tracing, risk estimating and source fingerprinting from coastal sediments of the Payra River in Bangladesh.

The Payra River, cicual for fish breeding, feeding and nursery in coastal Bangladesh, faces heavy contamination from industrial activities, agricultural runoff and poor waste management. This study used ICP-MS to assess metal contamination levels, risk status and potential sources in river sediment. The findings showed that the mean concentrations (mg/kg) of metals followed the decreasing order: Mn (434.

Abundance, distribution and composition of microplastics in sediment and fish species from an Urban River of Bangladesh.

Microplastics (MPs) are a growing concern due to its ubiquitous presence and exceptional stability. We examined the abundance, dispersion, and attributes of MPs in the sediment and fish species of the Turag River in Bangladesh, which separated the industrial city Gazipur from the Mega-city Dhaka. Collected samples were digested and the chemical structure was identified using ATR-FTIR spectroscopy.
