“…Considering the inter-annual variations of As and Hg concentrations in the study area (Table 1), the differences observed in our study were within this variation range (Huo, 2011). Moreover, the concentrations in our study were not higher than other areas in China (such as the Yellow Sea) or in other parts of the world, such as the Black Sea (Guo, 2011;Lan et al, 2014;Bat et al, 2017). The As concentrations in our study approached the standard of Grade I (<20 mg/g), and the Hg concentrations approached Grade II (<0.05 mg/g) according to the marine sediment quality guidelines established by the P. R. China (GB 18668-2002).…”

“…Holothuroids are deposit-feeders and live in close association with sediment, and feeds mainly detrital particles and associated microorganisms (WoRMS Editorial Board, 2018). Many studies 2017; indicated that heavy metals including Hg tend to accumulate in sediment. It is surprising that H. arenicola, H. pardalis, H. verrucosa and H. atra, which are benthic species and are associated with sediment, did not show the high levels of Hg.…”

Nowadays metal bioaccumulation in holothuroids is increasing and is a cause of worry owing to toxicity. In the present study the concentrations of mercury (Hg) were measured in holothuroids (Holothuria (Thymiosycia) arenicola Semper, 1868, Holothuria (Lessonothuria) pardalis Selenka, 1867, Holothuria (Lessonothuria) verrucosa Selenka, 1867 and Holothuria (Halodeima) atra Jaeger, 1833) collected during different seasons (pre-monsoon, monsoon, and post-monsoon) in 2015 at Buleji and Sunehri coasts of Karachi, Pakistan. Hg concentrations of tentacles were higher than those in muscle, tentacle and gut tissues of the pre-monsoon, monsoon and post-monsoon. The lowest Hg concentrations were found in muscle tissues at all seasons in Buleji and Sunehri coasts. The mean levels in the muscle tissues were 0.018 mg/kg dry wt. for H. arenicola, 0.024 mg/kg dry wt. for H. verrucosa, 0.026 mg/kg dry wt. for H. pardalis and 0.036 mg/kg dry wt. for H. Atra. The results indicate that according to the European Union legislation the Hg amounts in all tissues of holothurians is much lower than permitted levels. In terms of Estimated Weekly Intakes, this current work also proved that there was no likely health hazard to consumers on account of intake of sea cucumbers under the current consumption rate in Buleji and Sunehri coasts of Karachi, Arabian Sea.

The emergence of technology to produce nanoparticles (1 nm – 100 nm in size) has drawn significant researchers’ interests. Nanoparticles can boost the antimicrobial, catalytic, optical, and electrical conductivity properties, which cannot be achieved by their corresponding bulk. Among other noble metal nanoparticles, silver nanoparticles (AgNPs) have attained a special emphasis in the industry due to their superior physical, chemical, and biological properties, closely linked to their shapes, sizes, and morphologies. Proper knowledge of these NPs is essential to maximise the potential of biosynthesised AgNPs in various applications while mitigating risks to humans and the environment. This paper aims to critically review the global consumption of AgNPs and compare the AgNPs synthesis between conventional methods (physical and chemical) and current trend method (biological). Related work, advantages, and drawbacks are also highlighted. Pertinently, this review extensively discusses the current application of AgNPs in various fields. Lastly, the challenges and prospects of biosynthesised AgNPs, including application safety, oxidation, and stability, commercialisation, and sustainability of resources towards a green environment, were discussed.
