Bromoform (CHBr3) contributes to stratospheric ozone depletion but is not regulated under the Montreal Protocol due to its short lifetime and large natural sources. Here, we show that anthropogenic sources contribute significantly to the amount of CHBr3 transported into the Northern Hemisphere (NH) extratropical stratosphere. We present a new CHBr3 emission inventory comprised of natural and anthropogenic sources, with the latter estimated from ship ballast, power plant cooling and desalination plant brine water. Including anthropogenic sources in the new inventory increases CHBr3 emissions by up to 31.5% globally and 70.5% in the NH. In consequence, atmospheric CHBr3 is also significantly higher, especially over the NH extratropics during boreal winter. Here anthropogenic sources enhance bromine at the tropopause by 0.9 ppt Br, thus doubling natural CHBr3 abundances. For some latitudes, tropopause bromine increases by 2.4 ppt Br suggesting significant contributions of anthropogenic CHBr3 to the NH lowermost stratosphere.

“…Additionally, more active species were required for the extra pollutant molecules, but it was anticipated that the amount of free radicals produced would remain constant for a given catalytic dose, sunlight intensity, and time duration of sunlight irradiation. 50 Additionally, a portion of the active radicals produced during the breakdown of the ES and EBT metabolites may be consumed. As a result, there were not enough active radicals in the specific reaction mixture to effectively destroy a lot of contaminants.…”

Water pollution stemming from textile dyes, particularly methylene blue (MB), represents a formidable challenge to both the environment and human well-being. In response to this pressing issue, scientists have redirected their focus toward eco-friendly nanocatalysts as a viable remediation strategy. Nanocatalysts crafted from precious metals like platinum, palladium, and gold have indisputably demonstrated their efficacy in combatting water pollution. Nonetheless, their restricted availability and substantial costs have spurred investigations into non-precious metal-based nanocatalysts. Research outcomes have revealed that non-noble metal (FeNi)-based nanocatalysts, synthesized using natural reductants, exhibit highly promising performance in degrading methylene blue. These alternatives not only deliver impressive efficiency but also incur lower production expenses compared to their noble metal counterparts. The ecological benefits inherent in these nanocatalysts offer a sustainable means of mitigating water pollution attributed to textile dyes. Through detailed synthesis experiments, precipitation-assisted method demonstrated a slightly superior yield of 69.11% with catalytic activity of 16260 μmol MB/gNiFe.
