“…Phosphate-modified biochar and biochar produced from feedstocks that are rich in P such as animal carcass may remarkably reduce Cd and Pb bioavailability or bioaccessibility by forming stable precipitates [e.g., Cd 3 (PO 4 ) 2 , Cd 5 (PO 4 ) 3 Cl; Pb 5 (PO 4 ) 3 Cl, Pb 5 (PO 4 ) 3 OH, Pb 3 (PO 4 ) 2 ] (Chen et al 2019b;Deng et al 2019c;Penido et al 2019). Kastury et al (2019) also found that phosphaterich biochar (bone meal biochar) was effective in reducing the exposure risk of Pb to mice, which provides an effective remediation strategy to mitigate the exposure risk of heavy metals to animals (Kastury et al 2019). Iron (Fe) oxidesloaded biochars are still widely used in heavy metal remediation in 2019.…”

Biochar, derived from thermal pyrolysis of biomass, has been regarded as a low-cost, sustainable and beneficial material and widely applied in agriculture, environment and energy during the last two decades. To elucidate the research status timely and future trends in biochar field, CiteSpace is used to systematically analyze the related literature retrieved from the Web of Science core collection in 2019. Based on the keywords clustering analysis, it was found that "biochar production", "organic pollutants removal", "heavy metals immobilization", "bioremediation" were the main hotspots in research covering biochar. "Bioremediation" is an emerging topic and deserves extensive attention due to its highly effective and environmentally friendly treatment of pollutants. Improving the phytoremediation effect, immobilizing functional microorganisms on biochar, and using microorganisms as raw materials to produce biochar were the common methods of biochar-assisted bioremediation. While studies focused on "soil quality and plant growth" and "biochar and global climate change" decreased, investigations concentrated in the toxicity of biochar to soil biota and ruminants are sustainably growing. Research on direct and catalytic thermal pyrolysis of green waste (mainly microalgae) for biofuels (bio-oil, biodiesel, syngas, etc.) and biochar production is increasing. Converting municipal wastes (e.g., sewage sludge, fallen leaves) into biochar through pyrolysis was a suitable treatment for municipal waste and became a popular topic in recent time. Moreover, the biochar produced from these municipal wastes exhibited excellent performance in the removal of pollutants from wastewater and soil. This review may help to identify future directions in biochar research and applications.

“…Pb exposure can affect human health in various ways such as neurological disorders in children, malfunction of kidneys, cardiovascular problems, genotoxicity, and disruption of stress mechanisms which can cause neurotoxicity [ 56 , 57 ]. Incidental ingestion and inhalation of soil/dust particles are considered major sources of Pb exposure in human beings [ 57 ]. The heavy concentration of Pb in road dust samples of both cities indicates traffic as a major source of pollution.…”

The aim of this study is to identify and investigate levels of toxic heavy metals in PM2.5 fractioned road dust to better understand the associated inhalation risk and potential health impacts. To achieve this aim, concentrations of seven traffic generated heavy metals (Cu, Pb, Zn, Cd, Ni, Sb, and Cr) were determined in the PM2.5 fraction of road dust samples from four different locations (offices, residential, hospital, and school) in two cities (Karachi and Shikarpur) of Pakistan using ICP-MS. The average concentration values of heavy metals in Karachi were as follows: 332.9 mg/kg Cu, 426.6 mg/kg Pb, 4254.4 mg/kg Zn, 62.3 mg/kg Cd, 389.7 mg/kg Ni, 70.4 mg/kg Sb, 148.1 mg/kg Cr, whereas the average concentration values of heavy metals in Shikarpur were 245.8 mg/kg Cu, 538.4 mg/kg Pb, 8351.0 mg/kg Zn, 57.6 mg/kg Cd, 131.7 mg/kg Ni, 314.5 mg/kg Sb, 346.6 mg/kg Cr. The pollution level was assessed through two pollution indices enrichment factor (EF) and geoaccumulation index (Igeo). These indices showed moderate to extreme level pollution in studied areas of both cities. The health risk assessment through inhalation contact was conducted according to the United States Environmental Protection Agency’s (USEPA) model for children and adults. Both non-cancerous and cancerous risks were characterised in the road dust samples for each location. As yet, there is not a single study on the concentrations of heavy metals in PM2.5 fractions of road dust in Karachi and Shikarpur, findings of this research will facilitate researchers for further investigations in current field.

“…The samples were digested using a block digester (A.I. Scientific AIM500) by slowly ramping up the temperature to a maximum of 170 °C until the organs were dissolved and the samples dried to near evaporation (~ 1-2 mL) 55 . The samples were made up to 10 mL using MilliQ water, vortexed thoroughly to mix, syringe filtered (0.45 µm) to separate the dissolved metal(loid)s and stored at 4 °C Figure 1.…”

Naturally occurring metals and metalloids [metal(loid)s] are essential for the physiological functioning of wildlife; however, environmental contamination by metal(loid) and plastic pollutants is a health hazard. Metal(loid)s may interact with plastic in the environment and there is mixed evidence about whether plastic ingested by wildlife affects metal(loid) absorption/assimilation and concentration in the body. We examined ingested plastic and liver concentration of eleven metal(loid)s in two seabird species: fairy (Pachyptila turtur) and slender-billed prions (P. belcheri). We found significant relationships between ingested plastic and the concentrations of aluminium (Al), manganese (Mn), iron (Fe), cobalt (Co), copper (Cu) and zinc (Zn) in the liver of prions. We investigated whether the pattern of significant relationships reflected plastic-metal(loid) associations predicted in the scientific literature, including by transfer of metals from ingested plastics or malnutrition due to dietary dilution by plastics in the gut. We found some support for both associations, suggesting that ingested plastic may be connected with dietary dilution / lack of essential nutrients, especially iron, and potential transfer of zinc. We did not find a relationship between plastic and non-essential metal(loid)s, including lead. The effect of plastic was minor compared to that of dietary exposure to metal(oid)s, and small plastic loads (< 3 items) had no discernible link with metal(loid)s. This new evidence shows a relationship between plastic ingestion and liver metal(loid) concentrations in free-living wildlife.
