“…The LoD value is 12.74 ± 1.91 ppm, which meets the requirements of occupational exposure limits recommended by the American Conference of Governmental Industrial Hygienists (ACGIH)for the detection of Cl in VOCs. 27 In particular, compared to the conventional detection methods based on the atomic spectra of Cl (discussed in Section 3.1), the proposed method provides technical support for the fast determination of Cl in the air environment.…”

“…The PAHs influence on human health is determined chiefly by the time and method of exposure, the level of PAHs encountered, and the PAHs' relative toxicity (Dahlstrom & Bloomhuff, 2014). The short-term PAHS effects on human health include eye irritation, qualm, vomiting, diarrhea, disorientation, and skin irritation and inflammation (Unwin et al, 2006).…”

Polycyclic aromatic hydrocarbons (PAHs) are prevalent environmental pollutants produced by incomplete combustion of biomass including fossil fuels, wood, and coal. The majority of PAHs in the environment emits from anthropogenic activities, while some are released from naturally occurring phenomena, such as volcanic activities. Consequently, PAHs concentration is significantly higher in industrialized and urban areas than in rural areas. Human exposure to PAHs results in many health problems, depending on the PAH concentration type, time and method of exposure, and individual health status. The PAHs readily transport between soil, water, and the atmosphere. Four main processes involved in PAH transportation are volatilization, absorption, leaching, and erosion. However, many factors affect PAHs‘ transportation, including PAHs‘ molecular weight, vapor pressure, soil matrix, climate condition, and topography. Various remediation techniques have experimented in order to PAHs remove from the natural environment. Bioremediation, in particular, is an optimistic way that can be done by bacteria, fungi, and alga.

“…Although these coatings served the purpose of improved anti-galling properties but the fluorine present in them act as a biotransformation precursor i.e. it results in the metabolism imbalance in human body and sometime can result in trauma as during austere conditions fluoro-polymers gets degrade and releases hydrofluoric acids [77,172].…”

A review: advancements in fluoro-based polymers for aggrandizing anti-galling and wear resistant characteristics

Galling is the surface phenomenon which involves adhesion of local contact points and creation of protrusions on the juxtaposition of surfaces owing to high friction, inappropriate tribological loading, starved lubrication and high contact pressure (~ 1000 kPa). All these factors result in severe plastic deformation varying from 8000 to 10,000 µε (ε-strain) and diffusion of materials into one another, which consequently results in fatigue wear, surface roughness, tribocorrosion and seizing up of critical parts. The aim of the review is to analyze and summarizes the issue of galling, concurrently it also deals with the novel and economical mitigation method i.e. use of fluorine based coatings e.g. PTFE, owing to their lowest friction coefficient from 0.02 to 0.2 among other solids, high stiffness, high thermal stability and non-adherent characteristics that augments the mechanical and tribological properties and concurrently protect against hostile environments that eventually upsurges the life of components.
