“…The samples collected from near the Sutlej River had higher EC and TDS values compared to samples collected far from River Sutlej. This trend countered that reported in a previous study conducted in southern Punjab (Malana and Khosa 2011). A Piper plot of the major elements separated the groundwater types (Fig.…”

“…The highest As concentration was observed in the sample DW17 (tube well having depth of 52 m), whereas the lowest As concentration was observed in DW19 (hand pump having depth of 21 m). The As concentrations in Dur Pur were much lower than those found by studies conducted in East Punjab (Farooq et al 2007) and Muzaffargarh (Nickson et al 2005), but higher than those revealed in a previous study conducted in Dera Ghazi Khan (Malana and Khosa 2011). The results of the current study showed that the As concentration was higher in the regions located near to the Sutlej River compared to the areas located far from it.…”

“…Those samples taken from the Dur Pur area located far from the river had lower F − concentrations. The fluoride concentrations in the study area were much higher than those found in previous studies conducted in Sialkot (Ullah et al 2009), Dera Ghazi Khan (Malana and Khosa 2011), and North Jordan (Rukah and Alsokhny 2004).…”

“…In Pakistan, As and F − affected areas include Jamshoro, Sindh (Baig et al 2009a), Manchar Lake, Sindh (Arain et al 2008(Arain et al , 2009, Lahore and Kasur, Punjab (Farooqi et al 2007a, b), Muzaffargarh, Punjab (Nickson et al 2005), Dera Ghazi Khan, Punjab (Malana and Khosa 2011) and Tharparkar, Sindh (Brahman et al 2013a, b). In 2004, more than 40 people died in Hyderabad City from ingesting water contaminated with high levels of As and other toxic metals (Arain et al 2008).…”

The present study discusses elevated groundwater arsenic (As) and fluoride (F(-)) concentrations in Mailsi, Punjab, Pakistan, and links these elevated concentrations to health risks for the local residents. The results indicate that groundwater samples of two areas of Mailsi, Punjab were severely contaminated with As (5.9-507 ppb) and F(-) (5.5-29.6 ppm), as these values exceeded the permissible limits of World Health Organization (10 ppb for As and 1.5 ppm for F(-)). The groundwater samples were categorized by redox state. The major process controlling the As levels in groundwater was the adsorption of As onto PO4 (3-) at high pH. High alkalinity and low Ca(2+) and Mg(2+) concentrations promoted the higher F(-) and As concentrations in the groundwater. A positive correlation was observed between F(-) and As concentrations (r = 0.37; n = 52) and other major ions found in the groundwater of the studied area. The mineral saturation indices calculated by PHREEQC 2.1 suggested that a majority of samples were oversaturated with calcite and fluorite, leading to the dissolution of fluoride minerals at alkaline pH. Local inhabitants exhibited arsenicosis and fluorosis after exposure to environmental concentration doses of As and F(-). Estimated daily intake (EDI) and target hazard quotient (THQ) highlighted the risk factors borne by local residents. Multivariate statistical analysis further revealed that both geologic origins and anthropogenic activities contributed to As and F(-) contamination in the groundwater. We propose that pollutants originate, in part, from coal combusted at brick factories, and agricultural activities. Once generated, these pollutants were mobilized by the alkaline nature of the groundwater.

“…The presence of heavy metals in water sources is the result of industrial discharges especially those dealing with mining, manufacturing and processing tasks [84]. Heavy metals pose health hazards to man and aquatic life when exceed allowable limit in water [85]. The concentrations of heavy metals even if below these limits, have potential for long term contamination on account of their accumulative nature in biological systems [86].…”

A great deal of environmental concerns, oil price hike, and rapid oil consumption with finite nature of oil reserves in addition to consumer demand is driving research into renewable, biodegradable, inexpensive, and abundantly available biopolymers in material chemistry. Poultry feathers consist of keratin protein with several amino acids especially cysteine as a major component. Keratin is an original raw material that has great potential to be used in the development of novel fibrous composite materials. Being very effective biopolymer, keratin possesses numerous functional properties, bioactivities, and chemical applications in material chemistry, for example, keratin based gels, films, nano/micro-particles, and beads are of paramount importance. Modified keratin also serves as a biosorbent for removing toxic metal ions from water resources on account of exceptionally important role of functional groups for keratin-metal binding. This review focuses on the recent advances of keratin in material chemistry including its significant role as biosorbent in green chemistry.

Environmental pollution has increased many folds in recent years and in some places has reached levels that are toxic to living things. Among pollutant types, toxic heavy metals and metalloids are among the chemicals that pose the highest threat to biological systems (Jjemba 2004). Unlike organic pollutants, which are biodegradable, heavy metals are not degraded into less hazardous end products (Gupta et al. 2001). Low concentrations of some heavy metals are essential for life, but some of them like Hg, As, Pb and Cd are biologically non-essential and very toxic to living organisms. Even the essential metals may become toxic if they are present at a concentration above the permissible level (Puttaiah and Kiran 2008). For example, exposure to Zn and Fe oxides produce gastric disorder and vomiting, irritation of the skin and mucous membranes. Intake of Ni, Cr, Pb, Cd and Cu causes heart problems, leukemia and cancer, while Co and Mg can cause anemia and hypertension (Drasch et al. 2006). Similarly, various studies indicated that overexposure to heavy metals in air can cause cardiovascular disorders (Miller et al. 2007; Schwartz 2001), asthma (Wiwatanadate and Liwsrisakun 2011), bronchitis/emphysema (Pope 2000), and other respiratory diseases (Dominici et al. 2006).
