“…As an example, for the 2012-2013 field season, Lombard et al (2021) identified that drought in the conterminous United States increased the number of individuals exposed to elevated arsenic from 2.7 million to 4.1 million people (Lombard et al, 2021). Supporting this, Aribam et al (2021) found a strong correlation between climate change and groundwater arsenic seasonal variation.…”

View full text Add to dashboard Cite

The editorial focuses on four major themes contextualized in a virtual GeoHealth workshop that occurred from June 14 to 16, 2021. Topics in that workshop included drinking water and chronic chemical exposure, environmental injustice, public health and drinking water policy, and the fate, transport, and human impact of aqueous contaminants in the context of climate change. The intent of the workshop was to further define the field of GeoHealth . This workshop emphasized on chemical toxicants that drive human health. The major calls for action emerged from the workshop include enhancing community engagement, advocating for equity and justice, and training the next generation.

“…Once again, the increasing human population and excessive abstraction of groundwater for irrigation, domestic usage, and human consumption have caused a decline in groundwater quality. According to Aribam et al [47], there is a strong correlation between seasonal variations in groundwater levels of arsenic and climate change, in addition to how changing the climatic pattern affects the world's water supply.…”

In this study, climate change and human impacts on water quality in five major urban areas of Pakistan, including Karachi, Lahore, Peshawar, Abbottabad, and Gilgit, were determined. Secondary data on various physical, chemical, and bacteriological water quality parameters were taken from published papers, reports, and theses. Surface and groundwater were the major sources of drinking water in these cities. The physicochemical parameters were total turbidity, pH, dissolved solids (TDS), sulphates, chlorides, calcium, sodium, HCO3, potassium, magnesium, nitrates, fluorides, arsenic, and hardness. The bacteriological parameters were total coliform, total faecal coliform, and total plate counts. The data revealed that pH, TDS, fluoride, chloride, HCO3, sodium, and hardness were above the limits in Karachi. MCB Market, Goth Ibrahim, and Malir Town were the main contaminated areas in Karachi. In Lahore, arsenic was found above the limits in all sampling locations. Turbidity, pH, HCO3, calcium, magnesium, and hardness were found above the limits in Peshawar. In Gilgit city, all physicochemical parameters were found within the limits except turbidity, which was 10 NTU in Nomal valley. Nitrates were higher in the water sources in Abbottabad. Bacterial contamination was found in the water of all five cities. Most of the studies revealed that this contamination could be human-induced. The improper disposal of solid waste, sewage, and animal waste and the excessive use of fertilisers deteriorate the quality of the water. Precipitation, a rise in temperature, and seasonal variation are climate variables that affect water quality and are responsible for major outbreaks of waterborne diseases. There is an urgent need for regular analysis, proper management, and proper treatment of drinking water before it is supplied to the local community in these cities.

Removal of toxic metals from aqueous phase using cacao pod husk biochar in the era of green chemistry

2022

Cacao pod husk biochar was used as an adsorbent for the adsorption of toxic metals from aqueous phase. Cacao pod husk signifies a readily available source of eco-friendly and low-cost adsorbent in Sub-Saharan Africa that has scarcely been paid attention to. The experiment was conducted in a monosystem to determine how cacao pod husk biochar can efficiently adsorb lead (Pb2+), mercury (Hg2+) and cadmium (Cd2+) from aqueous phase. The experiment was conducted with 100 mL of varied toxic metal concentrations of the aqueous phase with a contact time of 60 min and a constant rotary speed of 14.8 U/min. The removal efficiency of cacao pod husk biochar for Pb2+, Hg2+ and Cd2+ ranged from 99.20 to 99.94%, 99.97 to 99.99%, and 99.85 to 99.99%, respectively. Freundlich adsorption isotherm was favourable for the adsorption of toxic metals onto the cacao pod husk biochar. The toxic metals had a stronger binding affinity to the cacao pod husk biochar. Hence, cacao pod husk was efficient for toxic metals elimination.
